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. When something goes wrong, this error-handling system usually displays some helpful message sometimes in the Console Window, so this is the first place to look when things aren't working.
In addition, you can create your own status and error messages to display here. As an example, let's execute something that will cause an error. Enter and run the following line of code in the Console Window:.
This line of code instructs Acrobat to open a file xx. Acrobat responds by generating an error, which is displayed by the Console Window, shown in Figure 8. This message is critical to understanding why the code failed, especially if the function call is buried in several lines of code inside another script. Always check the Console Window first when something goes wrong. Note that the second message on the line indicates a security error.
For our purposes, this is an erroneous and unhelpful message. There was no real security error, and while it may then seem that Adobe is deliberately trying to either terrify or confuse us, there is a reason the message is being displayed.
In fact, the message is not related to the JavaScript engine at all. It is the result of the Acrobat security model, which was made much more robust in versions 9, X, and XI by adding a security layer.
This layer blocks operations that don't fit with Acrobat's sense of rightness. JavaScript operations or errors that relate to external resources on the web or local file system tend to spook this security layer, which then throws out miscellaneous security errors. If you work with Acrobat JavaScript for any length of time, you'll find all sorts of operations that have nothing to do with security, but nonetheless generate security errors.
We can also create our own messages for display in the Console Window. This object provides a few functions for manipulating and accessing the Console Window, but for our purposes here the console. This function displays a single line of text on the next available line in the Console Window.
The following line of code displays the words "Hello Acrobat. You can also search for this author in PubMed Google Scholar. JavaScript is difficult to learn and this book explains it in simple steps at a beginner to intermediate level that a reader can later use to work in their own projects.
