files.length is undefined in Internet Explorer

Question

I'm using

$(upload_button).bind('change', function(event) 
{
    var files = this.files;
    alert(typeof(files));
    if(typeof(files)!='undefined')
    {


    }
});

in my code with jQuery which is working fine in Firefox and Chrome but not in IE8(i.e., IE returns undefined for files.length, whereas others returns the value). So do anybody know how to resolve this?

I suspect that `input` is not a good choice as variable identifier in IE... :) but maybe it's just me and I'm getting too old and suspicious — Fabrizio Calderan, Sep 26 '12 at 11:18
Which version of IE? IE6/7/8? `files` property doesn't work or `this`? — Ram, Sep 26 '12 at 11:18
Okay, what's the rest of the code (up to, and including, the `});` closing the `bind()` method)? And what part isn't working? — David Thomas, Sep 26 '12 at 11:18
why do you create `var file;`? You don't end the function correctly. How is `upload_button` referenced? — Niklas, Sep 26 '12 at 11:19
Could you give more details on which par do you have problem? — Anton Baksheiev, Sep 26 '12 at 11:24
what is upload_button? what line raises the error? what the error raised? — Fabrizio Calderan, Sep 26 '12 at 11:24

From jQuery API. change event will not work with button as I am assuming upload_button is button.

That's because Internet Explorer, even IE9 does not support HTML5 File API and therefore it returns undefined value for files property.

So is there any hack available for that? – Stranger Sep 26 '12 at 11:32

@Udhay I don't know, maybe IE10. http://msdn.microsoft.com/en-us/library/ie/hh772931(v=vs.85).aspx – Ram Sep 26 '12 at 11:51
