如何向ie8添加Int32Array支持

Question

I'm using scrypt.js for password encryption, in IE8 (apparently IE9 also) gives:

Int32Array is undefined

I've Googled around, and this is just plain unsupported by ie8 and ie9, there should I suspect be some way to add Int32Array support to javascript in ie8 ? Any leads appreciated.

Answer 1

if(typeof(Int32Array) == "undefined")
{
    Int32Array = function(size)
    {
        if(size < 0 || Math.floor(size) != size) { throw "Invalid array length"; } 
        for(var index = 0; index < size; index++) { this[index] = 0; }
        this.length = size;
    };
    Int32Array.prototype = new Array();
}
