How to write case insensitive Javascript search

Question

Example:

I have string "Waheed" so when try to search with small letters as "waheed" the results are not coming but when I search case it is working fine.. so how can I make it not case sensitive..? The table data is coming from php loop so iIcan not change it to lower or uppercase..! And this is my Javascript code:

$("#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();       
});

Don't see this as a duplicate... OP is not looking for a jQuery answer - not tagged. — rasmeister, Mar 10 '17 at 13:45
Could you make split the string and make the first letter caps — LiverpoolOwen, Mar 10 '17 at 13:47
Some people may write their name first letter as small so i can not do that @LiverpoolCoder — Mr world wide, Mar 10 '17 at 13:49
@AbdulWaheed I think you may need to use a RegExp and use the `i` flag. — evolutionxbox, Mar 10 '17 at 13:50
@rasmeister OP is trying to use jQuery Contains and the suggested duplicate shows how to make it work. Seems fine to me. — JLRishe, Mar 10 '17 at 13:50
the value variable will be filled from textbox right? and where are you comparing it in your code? — DevelopmentIsMyPassion, Mar 10 '17 at 14:04

$("#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.charAt(0).toUpperCase() + value.slice(1) +'")').parent('tr').show();       
});

maybe try something like this

There is a chance of getting the first letter as small as well @Liverpool – Mr world wide Mar 10 '17 at 14:02
This will make the first letter always capitalised – LiverpoolOwen Mar 10 '17 at 14:03
