var Cutoffvalue = document.getElementById(cut).innerHTML;

var arr1 = Cutoffvalue.split("(");

var val1 = arr1[1];

var arr2 = val1.split(")");

var cutof = arr2[0];

var cutoffmark = parseFloat(cutof, 10);

// var lblElement = document.getElementbyId("lblmaxmark");

$('#ctl00_ContentPlaceHolder1_lblmaxmark').html('Max-Mark is ' + cutoffmark);

}

 

 

function pageLoad() {


$('.textbox1').parent('td').hover(
function() {
// var sorted = $(this).find("input[type='text']");
//
