Javascript 区分大小写过滤器

Question

我正在使用下面的脚本来过滤表格中的结果。唯一的问题是它区分大小写。我将如何让它不区分大小写？

<script>
 $(document).ready(function() {

      $("#searchInput").keyup(function(){
    //hide all the rows
          $("#fbody").find("tr").hide();

    //split the current value of searchInput
          var data = this.value.split(" ");
    //create a jquery object of the rows
          var jo = $("#fbody").find("tr");

    //Recusively filter the jquery object to get results.
          $.each(data, function(i, v){
              jo = jo.filter("*:contains('"+v+"')");
          });
        //show the rows that match.
          jo.show();
     //Removes the placeholder text  

      }).focus(function(){
          this.value="";
          $(this).css({"color":"black"});
          $(this).unbind('focus');
      }).css({"color":"#C0C0C0"});

  });

</script>

http://jsfiddle.net/baeXs/和 http://css-tricks.com/snippets/jquery/make-jquery-contains-case-insensitive/会帮你的

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