Upgrading from 1.8 -> 1.9 "issues"

Hi Allan,

To begin, i wanna to thank you for your really great job for datatables =)

I wanna upgrade from 1.8 to 1.9, and i have noticed that the "highlight search function" found in this forum is broken (without any error in the javascript console).

The code here:

// HIGHLIGHT FCT
jQuery.fn.dataTableExt.oApi.fnSearchHighlighting = function(oSettings) {
    // Initialize regex cache
    oSettings.oPreviousSearch.oSearchCaches = {}
    oSettings.fnRowCallback = function( nRow, aData, iDisplayIndex, iDisplayIndexFull) {
        // Initialize search string array
        var searchStrings = [];
        var oApi = this.oApi;
        var cache = oSettings.oPreviousSearch.oSearchCaches;
        // Global search string
        // If there is a global search string, add it to the search string array
        if (oSettings.oPreviousSearch.sSearch) {
            searchStrings.push(oSettings.oPreviousSearch.sSearch);
        }
        // Individual column search option object
        // If there are individual column search strings, add them to the search string array
        if ((oSettings.aoPreSearchCols) && (oSettings.aoPreSearchCols.length > 0)) {
            for (i in oSettings.aoPreSearchCols) {
                if (oSettings.aoPreSearchCols[i].sSearch) {
                searchStrings.push(oSettings.aoPreSearchCols[i].sSearch);
                }
            }
        }
        // Create the regex built from one or more search string and cache as necessary
        if (searchStrings.length > 0) {
            var sSregex = searchStrings.join("|");
            if (!cache[sSregex]) {
                // This regex will avoid in HTML matches
                cache[sSregex] = new RegExp("("+sSregex+")(?!([^<]+)?>)", 'i');
            }
            var regex = cache[sSregex];
        }
        // Loop through the rows/fields for matches
        $('td', nRow).each( function(i) {
            // Take into account that ColVis may be in use
            var j = oApi._fnVisibleToColumnIndex( oSettings,i);
            // Only try to highlight if the cell is not empty or null
            if (aData[j]) {
                // If there is a search string try to match
                if ((typeof sSregex !== 'undefined') && (sSregex)) {
                    this.innerHTML = aData[j].replace( regex, function(matched) {
                        return "<span class='filterMatches'>"+matched+"</span>";
                    });
                }
                // Otherwise reset to a clean string
                else {
                    this.innerHTML = aData[j];
                }
            }
        });
        return nRow;
    };
    return this;
}

An idea?

Thanks a lot!
