This script that I found on SO seems to be giving IE8 problems. What could the issue with it be?

function titleCase (str, glue){
    glue = (glue) ? glue : ['of', 'for', 'and'];
    return str.replace(/(\w)(\w*)/g, function(_, i, r){
        var j = i.toUpperCase() + (r !== null ? r : "");
        return (glue.indexOf(j.toLowerCase())<0)?j:j.toLowerCase();
    });
}

It says about the line return (glue.indexOf(j.toLowerCase())<0)?j:j.toLowerCase();

Error: Object doesn't support this property or method

Also, it seems to take issue with line 14 of jquery. Which is the very first line that isn't a comment (function( window, undefined ) {. But that is when I have it "showing all script errors", so maybe that's just a warning and not really something that's causing it actual problems.

What data do you give it? And what version of jQuery? – mplungjan Feb 06 '13 at 22:06
@mplungjan jquery 1.8.2. Data was just text...ooh..but it was `encodeURIComponent`'d. Would that cause an issue? Aside from that, it's just alphanumeric text. – 1252748 Feb 06 '13 at 22:10
Show some please. JSFiddle.net is where to do that – mplungjan Feb 06 '13 at 22:13
@mplungjan Even with the `encodeURIComponent` taken off it still fails. Here's a [jsbin](http://jsbin.com/inowoc/1/edit) Thanks! – 1252748 Feb 06 '13 at 22:19
@mplungjan and I use like this: `for (var c in address_obj){address_obj[c] = titleCase(address_obj[c]);}` – 1252748 Feb 06 '13 at 22:22

Use jquery 1.9 and [inarray](http://api.jquery.com/jQuery.inArray/) – mplungjan Feb 07 '13 at 05:21
@mplungjan cool, I'll try that. Why jquery 1.9? – 1252748 Feb 07 '13 at 22:09
To make sure you tried the latest – mplungjan Feb 07 '13 at 23:48
