Thanks dion.alexander,
much of the blow code referenced from cdtj posts.
I have achieved my objective as below.
1. added a Eventlister
window.addEventListener('load', customerOrganisation, false);
window.attachEvent('onload', customerOrganisation);
2. function defination
function customerOrganisation() {
jq("[class=detailro]").each(function (index) {
var thisvar = jq("td[pdmqa='customer.organization.name']");
if (typeof(thisvar) !== "undefined") {
var customorg = (jq(thisvar).text());
if (typeof(customorg) !== "undefined") {
customorg.trim();
if (customorg.toLowerCase().indexOf("infocrossing") > -1) {
jq(thisvar).css('background-color', 'yellow');
}}}
});
}
Thank you.
