i have modified your js fiddle code now it working jsfiddle.net/rFGWZ/3406/

       $("#search").on("keyup", function() {
        var value = $(this).val();
       if(value!='') {
           $("table tbody tr").hide();
       }else{
           $("table tbody tr").show();
       }
         $('table tbody tr td:contains("'+value+'")').parent('tr').show(); 
       });

Basically your code is working but it is not picking up elements inside your tag try adding the following:

var id2 = $row.find("b:first").text();

and changing this:

if (id2.indexOf(value) !== 0) {

Then search based on the bold content and it should work

You could try it like this and search on each part individually:

$id = $row.find("td:first");
var id2 = $id.find("b:first").text();
var id3 = $id.find("p:first").text();
if (id2.indexOf(value) !== 0 && id3.indexOf(value) !== 0) {

Answer 3

$("#searchStudent").on("keyup", function() {
    var value = $(this).val();
    if(value!='') {
        $("table tbody tr").hide();
        }else{
        $("table tbody tr").show();
    }
    $('table tbody tr td:contains("'+value+'")').parent('tr').show(); 
});

I have resolved with this help.
