Answer 1

This add on have better feature for highlighting search text. if you have created datatable in a dialog , then on dialog reopen you need to reinitialize datatable.

In DatatableHighlighter.js

jQuery.fn.dataTableExt.oApi.fnSearchHighlighting = function(oSettings) {
    // Initialize regex cache
    oSettings.oPreviousSearch.oSearchCaches = {};

    oSettings.oApi._fnCallbackReg( oSettings, 'aoRowCallback', 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

     //   searchTxt=($('#filter_input input[type="text"]')?$('#filter_input input[type="text"]').val():"");
        var searchTxt = $('input[type="search"]').val();
        // console.log("txt" + searchTxt);
        if ((oSettings.aoPreSearchCols) && (oSettings.aoPreSearchCols.length > 0)) {
            for (var i in oSettings.aoPreSearchCols) {
                if (oSettings.aoPreSearchCols[i].sSearch) {
                searchStrings.push(searchTxt);
                }
            }
        }
        // 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]) {
                var regRules = "("
                ,   regRulesSplit = sSregex.split(' ');

                regRules += "("+ sSregex +")";
                for(var i=0; i)", 'ig');
                //cache[sSregex] = new RegExp(regRules+"", 'ig');
            }
            var regex = cache[sSregex];
        }

        // Loop through the rows/fields for matches
        jQuery('td', nRow).each( function(i) {

            // Take into account that ColVis may be in use
            var j = oApi._fnVisibleToColumnIndex( oSettings,i);

            if (aData) {
                // If there is a search string try to match
                if ((typeof sSregex !== 'undefined') && (sSregex)) {
                    //For removing previous added 
                    var element = $(this);//convert string to JQuery element
                    element.find("span").each(function(index) {
                        var text = $(this).text();//get span content
                        $(this).replaceWith(text);//replace all span with just content
                    }).remove();
                    var newString = element.html();//get back new string

                    this.innerHTML = newString.replace( regex, function(matched) {

                        return ""+matched+"";
                    });
                }
                // Otherwise reset to a clean string
                else {
                    //For removing previous added 
                    var element = $(this);//convert string to JQuery element
                    element.find("span").each(function(index) {
                        var text = $(this).text();//get span content
                        $(this).replaceWith(text);//replace all span with just content
                    }).remove();
                    var newString = element.html();
                    this.innerHTML = newString;//$(this).html()//$(this).text();
                }
            }
        });
        return nRow;
    }, 'row-highlight');
    return this;
};

and call it like this ....

$("#button").click(function() {
                  dTable = $('#infoTable').dataTable({"bPaginate": false,"bInfo" : false,"bFilter": true,"bSort":false, "autoWidth": false,"destroy": true,
              "columnDefs": [
                               { "width": "35%", "targets": 0 },
                               { "width": "65%", "targets": 1 }
                             ]});
          $(".dataTables_filter input[type='search']").val('');
          $("span[class='filterMatches']").contents().unwrap();
          dTable.fnSearchHighlighting();
          $("span[class='filterMatches']").contents().unwrap();


        $("#AboutDialog").dialog('open');

    });
