PDFill PDF Editor can create document-level JavaScript actions that apply to the entire PDF document. Try it out by putting several in different locations in a PDF, a Document script, a Page Action, different JavaScript Field Actions, and so on. To script activities such as creating form fields and resizing pages it is necessary to know the dimensions of a document page. In PDF this can.

In most cases, Mouse Up is the preferred trigger. On Receive Focus media clips only. On Lose Focus media clips only. The JavaScript language was developed by Netscape Communications as a means to create interactive web pages more easily. Adobe has enhanced JavaScript so that you can easily integrate this level of interactivity into your PDF documents. You can invoke JavaScript code using actions associated with bookmarks, links, and pages.

The Set Document Actions command lets you create document-level JavaScript actions that apply to the entire document. The most common uses for JavaScript in forms are formatting data, calculating data, validating data, and assigning an action. Field-level scripts are associated with a specific form field or fields, such as a button.

This type of script is executed when an event occurs, such as a Mouse Up action. These and other JavaScript resources are located on the Adobe website. Applying actions and scripts to PDFs Search.

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 the settings to take affect you'll need to close and reopen the Console Window. After these preferences have been set Figure 1 , you're ready to start using the Console Window. The shortcut key can be a bit 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 displayed by code built-into Acrobat and loaded on startup. Each line represents a JavaScript module loaded by Acrobat. If there were any problems with these modules, or any others that Acrobat loads, error messages would also be displayed here. Normally, we're not interested in these initial 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 line 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 result. 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 message.

Instead, as shown in Figure 5 , it 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 results immediately, than it is to debug it from 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 to a variable named 'sum'. As shown in Figure 6, the return value from this line of code 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 small 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 the 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 it anytime we want to 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 JavaScript 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 information to accomplish some other purpose, for example 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 writes 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. It's the folder path of the current document. Since the current document was just created with app. The result will look something like this:. Of course, this information is easily available in the Document Properties dialog. The advantage to using the Console Window is to make this information available to copy to the system clipboard for use with another script in Acrobat or for something else.

Besides testing code, the Console Window has one other important role in debugging JavaScript.

It is the standard location for displaying status and error messages. The Acrobat JavaScript environment has a built-in error handling system.
