efficient way to parse table to array object in IE

im having table with more than 1k rows and more than 7 columns, trying to parse into array object, i tried using jquery

$(tableSearch).each(function () {
    $('tr', $(this)).each(function (key, tr) {
     开发者_开发问答   var self = this;
        var obj = new Object();
        var rowPos = 0;
        $('td', tr).each(function (rowPos) {
            obj[_self.colModel[rowPos].name] = $(this).html();
        });
        obj['Key'] = 'Rec-' + key;
    });
});

in FF it takes 300 milli seconds, but in IE its taking 60 seconds :(

as u can compare its around 200 times slower.

is there any way to get performance in IE. i tried raw javascript methods also still in IE efficiency is not achieved.

help me!!!!!!!.. how can i get similar performance in all browsers.

THANKS in Advance

i got the solution IE can be faster if we implemented this way

table = document.getElementById("myGrid");
    for (i = 0; i < table.rows.length; i += 1) {
       var rowData = new Array();
       row = table.rows[i];
       for (j = 0; j < row.cells.length; j += 1) {
           cell = row.cells[j];
           rowData[j] = cell.innerHtml
       }
       obj.push(rowData);
    }

Note: disable debug mode if ur using any debugger.

then IE seems to be reasonable but cant be faster than FF or safari
