A javascript function that returns the item with the max length in an string array

Note that stritems in our case is a single string, containing other strings separated with comas.

function FindMaxItemLength(stritems)
{
var itemsArray=new Array()
itemsArray=stritems.split(",")

var i=0;
var j=0;
var val1='';
var val2='';
var ret_len = 0;

for (i=0;i {
val1=itemsArray[i];
for (j=0;j {
val2=itemsArray[j];
if (val2.length > val1.length)
{
ret_len = val2.length;
}
}
}

return ret_len;
}
