Hi Jey

For array filter in the javascript use this concept it may help you

var FiveplusArray=Arr1 .filter(Compare)

function Compare(element, index, array) {
for (i=0;i<Arr2.length;i++)
{
if(element != Arr2[i])
return (element)
}
}

Hi Jey

You can use this phototype function for filter its will work in IE7 also. i think it will helpfull for you

Array.prototype.filterArray = function(fun /*, thisp*/)
{
var len = this.length;
if (typeof fun != "function")
throw new TypeError();

var res = new Array();
var thisp = arguments[1];
for (var i = 0; i < len; i++)
{
if (i in this)
{
var val = this[i]; // in case fun mutates this
if (fun.call(thisp, val, i, this))
res.push(val);
}
}

return res;
};

Filter=Arr1.filterArray (Compare)

Hi,
Thanks it is really works fine.

is there any predefined functions to filter other than create this prototype functions?
