Acrobat Javascript Samples Scripts
This tutorial shows you how to work with the JavaScript features in Acrobat X. See what acrobzt all-new Acrobat DC can do javascfipt you. In previous versions of Acrobat this was called Batch Processing, and there is a treasure trove of information on creating and using Actions in articles and videos on this site.
There is also an Actions Exchangeoffering all kinds of fancy Actions roxio creator pro 2012 created by users — that can be downloaded. The "commands" that make up an Action are, for the most part, the standard operations on the regular menu items and tools in Acrobatsuch as deleting a page or applying security. Anyone who is downlkad familiar with Addobe will know these commands are fairly static. They are set tutorila to perform a specific activity, such as deleting page five of a PDF.
There is no way to set up the page-delete command tree be more flexible, больше на странице example, to delete the second-to-last page, for which the specific page number will change with the document length. To create an Action where the operational parameters are flexible requires scripting, and fortunately, the Actions Command Palette includes a command that runs JavaScript Figure 1.
It is worth the time to examine the scripts in these actions. It is simply not possible to get the kind of advance functionality /19535.txt in these Actions any other way. This article will explore the rules and techniques for writing such scripts. Figure 1 — The Execute JavaScript command provides the only way to apply automatic, non-interactive flexibility to an Action.
There are some big advantages to /15284.txt a script in an Action, as well as a number of serious limitations. It's important to understand both sides in order to write efficient, error-free scripts. In addition, as we'll see, to get the most out of an Action Script, a little creativity is needed to work around some of the limitations. Most of the scripting used in downloax Action is very straightforward, and is written in exactly the same way as the code placed in a folder-level trusted function.
For example, here is a single line of code that places the file name along the bottom edge of downloas pages in the PDF using the watermark function. The script is simple, but it makes a custom change to the PDF that could not be done with any of the other Action Commands. If the document has an existing watermark, frfe new footer text is added to that watermark, so the code does not destroy anything already on the PDF.
Notice that event. In this code, the " this " keyword could also have been used, but using the official, and explicit reference to the document object is a much better practice. Saving to a custom file name: Prk Actions Dialog provides several options for saving the files operated on, including посетить страницу источник for renaming kavascript files with prefixes and postfixes.
However, these additions to the file name привожу ссылку static. A script rfee the only way to provide a flexible, custom-file-name option. For example, here is a short script that appends the current date to the file name and saves it into a subfolder of the original file.
It seems like there is a lot to this script, but it is really just a simple set of text manipulations to build the destination file name and frfe. Building a report file This technique is very useful for analyzing documents.
The code in that example is very complex. A simplified version will be presented here. For this example, a script will be created that reports the number of pages for each document run through the Action. It was stated earlier that there is no way for the script to know whether a document is the first or last in the process, so a method is needed that does not depend on detecting the beginning or end of the Action process.
To deal with this issue, the script will use the report document itself. If no report document is open, then one will adobe acrobat x pro javascript tutorial free download opened.
If it is open, then the script ttutorial add information to it. In this example, it is assumed there is a generic report document, available in a known location. It is also assumed that the report document contains a list field where the collected data will be placed. Here's the script:.
The document object for the report doc is stored in the global object. The first line detects the existence of the doc object by testing a property of that object. If the document was never opened, or if the user closed the report doc from a previous run, then the JavaScript engine will throw an exception and the catch block will open adobe acrobat x pro javascript tutorial free download initialize the report document.
This is just one method. The report doc could have been detected in a different way. For example, the open report doc is also listed in the app.
The location of the report document is completely arbitrary; it could be placed anywhere that is convenient. In the Adobe acrobat x pro javascript tutorial free download Comment Summary Action, the report document is created at runtime using the app. Adobe acrobat x pro javascript tutorial free download also could have been done using the Report object. The important bit is to have an open PDF document to act as a repository for the collected data.
It's also a good idea to include fields on the report doc for displaying the time and date of the Action run, and maybe even the user name. Once the report document is open, data will be added to it every time the Action is run. To create a clean report document, this file should be saved to a new location and closed. The save action can be продолжить чтение to the startup code in the catch block, for addobe saving to the folder of the first document.
This javascriipt the best place to put an automatic save. There is no easy way узнать больше здесь know when the last document is processed, so the save, if it is added to the code, has to happen when the document is first opened.
Getting user input at the acrobay of the process For some actions it is necessary to ask the user for input parameters in order to run the Action. If the same parameters tutorlal be used for all documents processed, then this should happen adobe acrobat x pro javascript tutorial free download once, at the beginning of the process.
The challenge, of course, is detecting the beginning of acrobah process. The answer to this challenge is provided by the previous example that uses a report document. The report document can be used as a kind of marker to determine the state of the process.
If the report document is not open, then the Action has just started and the script displays a popup or custom dialog for collecting data. If the report document is fres open, adobe acrobat x pro javascript tutorial free download the script proceeds with the business logic of the Action.
This technique works nicely, but it is a bit awkward because the report tutoriao still open when the Action jaavascript complete. If the user wants to run the Action with adobe acrobat x pro javascript tutorial free download parameters, they must close the report document.
Unfortunately, there aren't any other less-awkward solutions. Here's a short demo script that shortens the number of pages in a PDF to the number of pages specified by the user. The business logic for this script is only two lines of code, i. Everything else is javascrript. The script starts off by testing for both the existence of the report doc and the global. If either adobe acrobat x pro javascript tutorial free download not exist, then the report document is opened and the user is asked to enter the page length used to truncate the PDFs.
The code setup guarantees the user will only be asked to enter this information at the beginning of the Action execution. This is where things get interesting. The response box is displayed inside a while loop. This is a simple technique for ensuring the user enters a valid value, in this case, a number.
The loop will continue to display the response box until the tutodial either enters a valid number javazcript cancels the Action altogether. This second bit is handled by an alert box that is only displayed if the data entered by the user is adobe acrobat x pro javascript tutorial free download. The user is asked if they want to continue the process. If they answer "yes," then the response box is displayed so downolad can enter another number.
If they acroba "no", then event. The code in that Action is much more complex than what is shown here, but the technique is the same. In a working script, the popup messages should be more verbose and information about the process should be written to the report document. Try Acrobat DC. Learn how to edit PDF. Get started.

Adobe acrobat x pro javascript tutorial free download
Javascrpt Console Window is the best of the bunch. The other tools are very useful and have much better performance and stability in Acrobat XI than in previous versions. However, the Console Window remains many adobe acrobat x pro javascript tutorial free download faster and easier to use than the other tools, as well as being error free.
The Console Window is a tutprial and somewhat generic tool. It is the default location where JavaScript error messages are displayed as well as being an entry window for testing and debugging Acrobat JavaScript code. It can also be used to execute code snippets to automate tasks in Acrobat and to analyze documents. It does not do everything needed to debug code, but it does provide a quick and easy way to perform most of the code development tasks you'll ever need to do. In this article, we'll cover setting eownload and using this essential tool.
Note: Special instructions for using the Console Window with Reader are provided at the end of the article. If this is adobe acrobat x pro javascript tutorial free download first time using the Console Window, you will need to enable and configure it from Acrobat's Preferences settings. /27178.txt on your platform, use one of the following methods to open the Preferences dialog Figure 1.
In Preferences, select the JavaScript panel. These are the two most important preference javaecript. In fact, both of these settings may already be checked. JavaScript is turned on by default, and Acrobat will automatically ask you if you want to turn on the Console Window if you attempt to use it. It is not a good idea to check Enable JavaScript debugger after Acrobat is restarted, except in two downlod. First, you can enable it temporarily in order to change the "Exception" options.
I prefer the options as they are shown in Figure 1, but uncheck this option before exiting the preferences. The reason for not enabling the debugger is because it has a significant negative impact on Acrobat performance, and can even cause Acrobat to crash. So the only reason you would actually turn on the debugger is if you needed to use the debugging tools.
If you don't already know how to use software debugging tools, you are much better off sticking to the Console Window. A very useful feature is the external JavaScript editor, since the default Acrobat editor is very basic. A good JavaScript editor will have advanced features that make code manipulation and navigation easier when you are editing document code.
You won't be using the JavaScript editor with adobe acrobat x pro javascript tutorial free download Console Window, but this group of settings has an interesting effect on it. The Acrobat editor font and size settings are the same settings used in the Console Window. You can see in Figure 1 that I have chosen to use an external editor. This selection disables the Acrobat editor and grays out the font and size settings.
However, these are still the settings used by the Console Window. If you want to change them you'll need to temporarily enable the Acrobat editor to modify the settings, then reselect the external editor.
In order for por settings to take affect you'll need to close and reopen the Console Window. After these preferences have been set Figure 1you're ready to start using the Console Window.
The shortcut key can be a coreldraw suite 12 license key 2018 jeuxvideo tricky on the Macintosh because there are slight differences between the keyboards on laptop and desktop systems. So the keyboard shortcut is not always valid, but the tool button will always work. The tool panels are a new feature introduced in Acrobat X, so displaying the Console in earlier versions is slightly different.
The Shortcut key is the same, but instead of a tool button, these earlier versions use a menu item. The Console Window section of the Debugger is in the bottom portion of the dialog, in the area labeled View. In Figure 3, the View pull-down selection list is set to Console, meaning the Console Window is being shown.
This area is also used to show the Script window for displaying runtime code when the debugger tools are enabled. In the figure, the Console is being shown immediately after Acrobat was started.
The status messages are odwnload by code built-into Acrobat and loaded on startup. Each line represents a JavaScript module loaded adobw Acrobat. If there were any problems with these modules, or any others that Acrobat loads, error messages would also be adobbe here. Normally, we're not javascgipt in these adobs messages.
So if you would like to try out some of the code presented here as examples, then clear the window by pressing the button that looks like a garbage can in the lower right corner of the window. Now we have a clean work area and are set up and ready to start using the Console Window. JavaScript code can be executed directly from the Console Window. This ability is a huge time saver since it provides a fast and easy way to test out code before it's placed into a scripting location where it will be more difficult to debug.
To run the code, make sure the cursor is on the same tutlrial as the text. You can place it anywhere on the line as long as nothing is selected. Either of the two following actions will cause Acrobat to run the code. Acrobat always attempts to convert the result of an execution into text so that it can be displayed. Sometimes the result of an operation is not as clean or obvious as a number.
Let's try something that doesn't have such a well-defined adobe acrobat x pro javascript tutorial free download. Enter the following line in the Console Window and run it:.
This calculation has an obvious mathematical error, but Acrobat JavaScript doesn't display an error adobe acrobat x pro javascript tutorial free download. Instead, as shown in Figure 5it displays the word "Infinity. It is much easier to find this kind of issue by executing individual lines in the Console Window where you can see the adohe immediately, than it is to debug it нажмите чтобы увидеть больше a field-calculation script.
The next line of example code is something that might be used in a real script. It assigns a simple addition adobe acrobat x pro javascript tutorial free download a variable named 'sum'.
As shown in Figure adobe acrobat x pro javascript tutorial free download, the return value from this line of перейти на страницу is "undefined.
The calculation is executed and applied to the declared variable, sum. However, the first and primary operation on the line is the variable declaration, so this is the operation that returns a value to the Console Window. Unfortunately, variable declarations do not return a value. To overcome this javasccript issue, the Console widow displays "undefined. Anything that doesn't exist to the JavaScript environment is "undefined. This action executes just the selected text. This technique of selecting parts of the code for execution is also useful for executing multiple lines of code.
So far we've talked about executing code in adobe acrobat x pro javascript tutorial free download Console Window for testing and debugging, but there is no reason to restrict our usage to this limited theme. Immediate Mode means that anything entered into this window is executed directly by the JavaScript engine. We can use adobe acrobat x pro javascript tutorial free download anytime we want tutrial execute code for any purpose.
Two uses for the Console Window besides code testing that immediately come to mind are automation and analysis. There are several functions in Acrobat for manipulating and for acquiring information from PDFs and Acrobat. For operations with a user interface button or menu item, the main advantage of using Верно!
microsoft office 2013 portable cracked free download попки!)) is greater flexibility, since JavaScript functions typically provide more options than the user interface equivalent. For example, suppose you wanted to know the exact border color of a text field so you could use the same color in another location. Assuming the current document has a field with the correct name on it, the following code displays the raw color value in the Console Window:.
The result of this operation is a color array. Remember, Acrobat attempts to convert all results into text. Arrays are converted to text by converting each individual array element into a text string, so the result would look something like the following line when it is displayed in the Console Window.
This is an example of document analysis with JavaScript. We've just found out something that would have taken us just a little more effort to find out using the Acrobat property dialogs, and the information is in a very usable format. We can easily copy and paste this adobe acrobat x pro javascript tutorial free download to accomplish some other purpose, for adobe acrobat x pro javascript tutorial free download applying the color to another field with this line of code:.
Suppose a document needs to be checked for branding purposes, i. The following code uses a simple loop to display this color info in the Console Window for manual inspection:. Because of the loop, this code cannot be executed one line at a time. It has to be done all at once.
Notice that in the loop there is a function called console. It's in the fourth line. This function pri text to the Console Window and it will be discussed in the next section.
Here's an example of a function that does not have an easy equivalent on the regular Acrobat menus and toolbars. Enter the following line into the Console Window and run it:. Acrobat will create a new, blank PDF document. This is perfect for trying out new ideas before applying them to a working document. The results of this operation are shown in Figure 7 below.
Note that yet again, the result is something different. The result shown in Figure 7 tells us the type of object created. This result is only useful in letting us know the function worked. If app. Both of these situations would have been displayed in the Console Window.
The path property is exactly what you might think it should be.
