IntelliJ IDEA 2016.3 Help

Running and Debugging JavaScript

This feature is supported in the Ultimate edition only.

In this section:

To run a file with injected JavaScript from IntelliJ IDEA

No run configuration is required for launching applications with injected JavaScript from IntelliJ IDEA. You just open the HTML page with the reference to the required script in the browser and that's it.

  1. In the editor, open the HTML file with the JavaScript reference. This HTML file does not necessarily have to be the one that implements the starting page of the application.
  2. Do one of the following:
    • Choose View | Preview file in on the main menu or press Alt+F2. Then select the desired browser from the pop-up menu.
    • Hover your mouse pointer over the code to show the browser icons bar: /help/img/idea/2016.3/browserIcons.png Click the icon that indicates the desired browser.

To debug JavaScript code, perform these general steps:

  1. Configure the JavaScript debugger.
  2. Configure and set breakpoints in the JavaScript code as required.
  3. Initiate a debugging session.
  4. If you are using Chrome or Dartium, install and configure the JetBrains Chrome Extension. For details, see Using JetBrains Chrome Extension.
  5. Step through the program, stop and resume program execution, examine it when suspended, etc.
