Question

I know the files property is read only. but why could not assign this property to another variable? it works in firefox, but not ie.

My code is:

    var element=document.getElementById("fileinput");
    var files=document.getElementById("fileinput").files;
    alert(element);    //here can output HTTPInputElement
    alert(files);      //but here is always undefined in ie;

I do not know why the four line always give me undefined in ie.
How can I get the filelist object from input|files as variable in ie?

Answer 1

IE9 and below don’t have a files property because they only accept one file at a time.

IE: input type="file" multiple

IE10 is supposed to add actual support, I have not tested it yet.
