In this article, we'll cover setting up and using this essential tool. Special instructions for using the Console Window with Reader are provided at the end of the article. If this is your first time using the Console Window, you will need to enable and configure it from Acrobat's Preferences settings. Depending on your platform, use one of the following methods to open the Preferences dialog Figure 1.
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.
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 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.
Now we have a clean work area and are set up and ready to start using the Console Window.
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.
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.
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.
