How to set breakpoints in inline Javascript in Google Chrome?

Are you talking about code within <script> tags, or in the HTML tag attributes, like this?

<a href="#" onclick="alert('this is inline JS');return false;">Click</a>

Either way, the debugger keyword like this will work:

<a href="#" onclick="debugger; alert('this is inline JS');return false;">Click</a>

N.B. Chrome won’t pause at debuggers if the dev tools are not open.


You can also set property breakpoints in JS files and <script> tags:

  1. Click the Sources tab
  2. Click the Show Navigator icon and select the a file
  3. Double-click the a line number in the left-hand margin. A corresponding row is added to the Breakpoints panel (4).
