对象不支持属性或方法“匹配”-jQuery / ie8

Question

I am using the following code to write on a cookie, it works pretty well on all browsers except ie8:

var x = $.cookie(printedcookie); //991_0|590_0|995_0|996_0|564_0
var y = $.cookie(cookie);  // 991~1.20~/assets/img1.jpg|564~1.50~/assets/img2.jpg|201~1.10~/assets/img3.jpg|999~1.20~/assets/img4.jpg

var needles = x.split('|')
var haystack = y.split('|');
var newArray = $(haystack).filter(function (value) {
    for (var ii=0; ii<needles.length; ii++) {
        var needle = needles[ii].split('_')[0];
        var needleRegex = new RegExp("^" + needle);
        if(value.match(needleRegex)) {
            return false;
        }
    }
    return true;
});
$.cookie(cookie,newArray.join('|'),{ path: '/' , domain:domain, expires:365 });

I am expecting the final output to be:

201~1.10~/assets/img3.jpg|999~1.20~/assets/img4.jpg

What I am trying to achieve is: check if the first part of each item in var x is contained in y. If so remove this value, together with the remaining bit.

Any help would much be appreciated

IE throws an error : Error: Object doesn't support property or method 'match'

Instead of .match() you should use other alternative functions like

contains(),

hasClass(),

etc .. according to your logic.
