IntelliJ IDEA 12.1.0 Web Help

Some features described here are available in Ultimate edition only.

At the IntelliJ IDEA level, debugging of JavaScript injections is supported through the JavaScript Debugger bundled plugin, which is by default enabled. If not, activate it in the Plugins page of the Settings dialog box.

Debugging of JavaScript code is supported in the Firefox and Google Chrome browsers by means of browser-specific JetBrains extensions. No special steps are required from your side to install or enable these extensions. IntelliJ IDEA does it for when you initiate a debugging session for the first time.

During a debugging session, IntelliJ IDEA considers any injected JavaScript code in a Web page opened in the browser as subject for debugging. This means that you cannot use the same instance of a browser for browsing and for debugging simultaneously. For Google Chrome you can solve this problem by configuring IntelliJ IDEA to use a separate Chrome user profile for debugging.

In this section:

To configure settings required for debugging JavaScript code
  1. Open the Project Settings dialog box, click Debugger and select JavaScript.
  2. On the Debugger. JavaScript page that opens specify:
    • In the Value tooltip delay (ms) field, specify the time period between pointing at an object and displaying the object's value in a tooltip.
    • Whether to display DOM properties in a tab or not.
    • Whether to display function values in a tab or not. If you want the function values to be shown only for user-defined functions, select the Show only user-defined functions. (Otherwise, the function values will be shown for all function.)
    • Whether you want object node properties to be shown. If so, specify the properties. Use add and delete to manage the list of properties.
    • Whether you want the debugger to skip certain scripts. If so, specify URLs for the corresponding scripts. Use add and delete to manage the list of script URLs.
