Question

Can some of you please tell me why a simple alert() isn’t working using jQuery 1.4 in Internet Explorer 7, when it’s working in all other browsers? It’s been driving me crazy now for the last half an hour..!

$(document).ready(function(){
    alert("wtf?");
})

This simple example doesn’t show an alert in IE7. See for yourself at http://jsfiddle.net/8HQdp/.

Answer 1

1. Ensure your console doesn’t show any errors and correct them if there are any.
2. Be sure you didn’t disable browser prompts on IE
3. Try using window.alert() – it’s possible (though improbable) that another alert() is conflicting with window‘s.

4. If you have console support, try console.log(alert); and see what it says. It should be something like:

   function alert() {
       [native code]
   }
