Detecting JavaScript errors in Chrome

Question

Chrome does not appear to give any indication that a page has JavaScript errors, unless you open up the JavaScript Console to check.

Is there any way to have an indication that there were errors, and then automatically open the JavaScript Console? Can the JavaScript console be opened from JavaScript?

Answer 1

Chrome does not have a native ability to alert you to Javascript errors. However, this Chrome extension will show an alert icon in the address bar when a Javascript error occurs:

The extension can be installed here:

Answer 2

I think you cannot open the console directly from your JavaScript code. And as far as I know, only Opera has the option to display the console automatically, right after any error occurs.

Answer 3

不。甚至调用console.log也不会显示控制台。
