stop script debug error dialogs occur in ie8 ?

Question

I get this,

clicking 'no' means the page displays flawlessly.

it's refering to this part of jquery1.4.2.js:

// Get the Nth element in the matched element set OR
// Get the whole matched element set as a clean array
get: function( num ) {
    return num == null ?

        // Return a 'clean' array
        this.toArray() :

        // Return just the object
        ( num < 0 ? this.slice(num)[ 0 ] : this[ num ] );
},

I assume i'm calling something in the wrong context somewhere in one of my js files (which would be a real mission to find).

Will standard IE8 users get this error?

(i imagine ms make it pretty difficult to reinstall ie!)

my javascript:

var IE = /*@cc_on!@*/false;

Answer 1

They'll get a little yellow icon in the bottom, or else they'll see exactly what you see, depending on the way the browser is set up. I suspect that, in some way, your page is not without flaw. You should be able to use the developer tools to check a stack trace and figure out where in your code the error is happening. Alternatively, you can bracket code with try/catch blocks and seek out the error that way.

[edit] Here's what the browser shows, in the lower left corner:

Double-clicking on that brings up the same error dialog you see.
