search case insensitive letters in textbox

Question

I am trying to search the contents using jquery. Search option working fine. But, I have faced some case insensitive problem here. My full codes on jsfiddle. if i put senthil in my search it didn't show the result. Because, I have Senthil (Uppercase S) in my content. How do I find Uppercase letters in jquery?

JsFiddle

$('#search').on('input', function(){
                var text = $(this).val();
                $('.subjects a').show();    
                $('.subjects a:not(:contains(' + text + '))').hide();
                $('.subjects a span').show();
            });

You can use a custom expression for contains like this:

$.expr[":"].contains = $.expr.createPseudo(function(arg) {
    return function( elem ) {
        return $(elem).text().toUpperCase().indexOf(arg.toUpperCase()) >= 0;
    };
});

Add this code to your JS code

$.expr[":"].contains = $.expr.createPseudo(function(arg) {
    return function( elem ) {
        return $(elem).text().toUpperCase().indexOf(arg.toUpperCase()) >= 0;
    };
});
