Is there a case insensitive jQuery :contains selector?

Question

Is there a case insensitive version of the :contains jQuery selector or should I do the work manually by looping over all elements and comparing their .text() to my string?<

Answer 1

Refer below to use ":contains" to find text ignoring its case sensitivity from an HTML code,

 $.expr[":"].contains = $.expr.createPseudo(function(arg) {
            return function( elem ) {
                return $(elem).text().toUpperCase().indexOf(arg.toUpperCase()) >= 0;
            };
        });
        $("#searchTextBox").keypress(function() {
          if($("#searchTextBox").val().length > 0){
            $(".rows").css("display","none");
            var userSerarchField = $("#searchTextBox").val();
            $(".rows:contains('"+ userSerarchField +"')").css("display","block");
          } else {
            $(".rows").css("display","block");
          }              
        });
