Split Problem Internet Explorer

After an earlier question relating to this error.

Error: unable to get value of the property ‘split’: object is null or undefined

An answer was offered to add the following code:

/* Cross-Browser Split 1.0.1

var cbSplit;

// avoid running twice, which would break `cbSplit._nativeSplit`'s reference to the native `split`
if (!cbSplit) {

cbSplit = function (str, separator, limit) {
    // if `separator` is not a regex, use the native `split`
    if (Object.prototype.toString.call(separator) !== "[object RegExp]") {
        return cbSplit._nativeSplit.call(str, separator, limit);
    }

    var output = [],
        lastLastIndex = 0,
        flags = (separator.ignoreCase ? "i" : "") +
                (separator.multiline  ? "m" : "") +
                (separator.sticky     ? "y" : ""),
        separator = RegExp(separator.source, flags + "g"), // make `global` and avoid `lastIndex` issues by working with a copy
        separator2, match, lastIndex, lastLength;

    str = str + ""; // type conversion
    if (!cbSplit._compliantExecNpcg) {
        separator2 = RegExp("^" + separator.source + "$(?!\\s)", flags); // doesn't need /g or /y, but they don't hurt
    }

    /* behavior for `limit`: if it's...
    - `undefined`: no limit.
    - `NaN` or zero: return an empty array.
    - a 开发者_StackOverflow社区positive number: use `Math.floor(limit)`.
    - a negative number: no limit.
    - other: type-convert, then use the above rules. */
    if (limit === undefined || +limit < 0) {
        limit = Infinity;
    } else {
        limit = Math.floor(+limit);
        if (!limit) {
            return [];
        }
    }

    while (match = separator.exec(str)) {
        lastIndex = match.index + match[0].length; // `separator.lastIndex` is not reliable cross-browser

        if (lastIndex > lastLastIndex) {
            output.push(str.slice(lastLastIndex, match.index));

            // fix browsers whose `exec` methods don't consistently return `undefined` for nonparticipating capturing groups
            if (!cbSplit._compliantExecNpcg && match.length > 1) {
                match[0].replace(separator2, function () {
                    for (var i = 1; i < arguments.length - 2; i++) {
                        if (arguments[i] === undefined) {
                            match[i] = undefined;
                        }
                    }
                });
            }

            if (match.length > 1 && match.index < str.length) {
                Array.prototype.push.apply(output, match.slice(1));
            }

            lastLength = match[0].length;
            lastLastIndex = lastIndex;

            if (output.length >= limit) {
                break;
            }
        }

        if (separator.lastIndex === match.index) {
            separator.lastIndex++; // avoid an infinite loop
        }
    }

    if (lastLastIndex === str.length) {
        if (lastLength || !separator.test("")) {
            output.push("");
        }

        output.push(str.slice(lastLastIndex));
    }

    return output.length > limit ? output.slice(0, limit) : output;
};

cbSplit._compliantExecNpcg = /()??/.exec("")[1] === undefined; // NPCG: nonparticipating capturing group
cbSplit._nativeSplit = String.prototype.split;

} // end `if (!cbSplit)`

// for convenience...
String.prototype.split = function (separator, limit) {
    return cbSplit(this, separator, limit);
};

After trialling the code above and deleting caches it was found to do nothing...can anyone help at all, kind regards in advance.

Thanks EdoDodo for the above code but can you offer any further help as I am almost tearing my hair out and it did not work in the end, one point to note, the linked in button on the home page (if commented out) makes that site work for the home page and the error goes away but I really want the linked in buttons for each post excerpt on the home page.

site is:

www.mobileinquirer.com

Firefox shows me a script error on line 913 in this part of your script:

<script type="text/javascript">
    // <![CDATA[
        var disqus_shortname = 'mobileinquirer';
        var disqus_domain = 'disqus.com';
        (function () {
            var nodes = document.getElementsByTagName('span');
            for (var i = 0, url; i < nodes.length; i++) {
                if (nodes[i].className.indexOf('dsq-postid') != -1) {
                    nodes[i].parentNode.setAttribute('data-disqus-identifier', nodes[i].getAttribute('rel'));
                    url = nodes[i].parentNode.href.split('#', 1);
                    if (url.length == 1) url = url[0];
                    else url = url[1]
                    nodes[i].parentNode.href = url + '#disqus_thread';
                }
            }
            var s = document.createElement('script'); s.async = true;
            s.type = 'text/javascript';
            s.src = 'http://' + disqus_domain + '/forums/' + disqus_shortname + '/count.js';
            (document.getElementsByTagName('HEAD')[0] || document.getElementsByTagName('BODY')[0]).appendChild(s);
        }());
    //]]>
    </script>

The specific error is on this line:

url = nodes[i].parentNode.href.split('#', 1);

and it's because parentNode does not have an href. This error has nothing to do with the split function. The code is trying to obtain the value of the href attribute on the parentNode, but there is no href attribute so that resolves to undefined so the call to split fails. It has nothing to do with the split function. The issue is that your markup is apparently wrong and what I think is disqus code is expecting an tag around a tag, but it isn't finding that.

If you look at line 664-665 in the mobilinquirer.com HTML source, you will find this sequence at that line and then several times following:

<p><span
class="dsq-postid">8 Comments</span></p>

This code causes the error. The <span class="dsq-postid"> tag must have an <a href="xxx"> tag as it's parent or you will get this error. I see this same problem several problems in your HTML.

This problem has NOTHING to do with the split function. To make this error go away, you need to fix your HTML so that it is what the disqus code is expecting or remove the offending disqus code (which you don't seem to need) or both.
