This is weird, The following line of javascript:

alert("test");

gives the following error in chrome:

Uncaught TypeError: Property 'alert' of object [object DOMWindow] is not a function

It also breaks when using a prompt. Oddly it works in firefox. Any ideas?

  • I am not able to replicate this error when placing this command alone in a document and viewing it in Chrome. Do you have any other scripts loading on the page? – Chris Baker Feb 14 '11 at 19:38

    Love the fact some many people jump down the poster's throat about being a bad developer. Show some love on VD [and hopefully not a VD.] :) End result was some other developer's poorly written plug-in that caused the bug. You can go rip that developer[s] a new one. lol – epascarello Feb 14 '11 at 20:26

    If you set a variable name to "alert" you can have this problem as well. var alert = $('
    Nope
    '); alert('Message'); // Error     – BigToach Nov 01 '12 at 20:35

Do you have a another pop up blocker plug-in installed on Chrome? If you do, disable/remove it and see if the error goes away.

  • Good call. That was it. I installed better popup blocker for chromium cause last week and added an exception and it worked! Thanks! – Frank Conry Feb 14 '11 at 20:16

Is your Javascript enabled in the Chrome options? Other thing is any other js library included which might change default js behaviour?

As epascarello said its because of popup blocker plugin and I faced this problem with my localhost websites and prompt method.
So i fixed it by adding my localhost url to popup blocker's whitelist: http://localhost
