Indexof operation not working in IE8 RRS feed

  • Question

  • HI all,

              Am using IE11, in Javascript am using Indexof() its working fine here, but its not working in IE8. Please find the code below. Request any one to fix it and alter this code and share it. Thanks in advance..

    function Form_onload() {

        var haystack_array = Xrm.Page.context.getUserRoles();
        var i = haystack_array.indexOf('af259ead-ca7d-e311-b157-0050568074ef'); // Working fine in IE11 not in IE 8

  • Hi Jerry,

    IndexOf() isn't supported by IE8. Use the following code to make it work

    if (!Array.prototype.indexOf)
        Array.prototype.indexOf = function (obj, start)
            for (var i = (start || 0), j = this.length; i < j; i++)
                 if (this[i] === obj) { return i; }
             return -1;

  • Hi Dynamotion,

    How to use this code for my assigned value haystack_array.

  • I believe once you add the above code, your existing line of code should work as is. The above code provided by DynaMotion defines an IndexOf function for an Array which is missing in IE 8 and therefore it  errors for you.

    You need to include the function in your script library as a separate function.

    Hope i have got this right

  • Hi Jerry,

    Just copy paste this snippet in your code file, and there's nothing else you need to do. You indexOf() line will start working in IE8.
