JavaScript區分大小寫過濾器

Question

我正在使用下面的腳本來過濾表中的結果。 唯一的問題是它區分大小寫。 我將如何使其不區分大小寫？

<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/將幫助您

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

可以用filter()做這樣的事情：

 $.each(data, function (i, v) {
     v = v.toLowerCase();    
     jo.filter(function () {
         var txt = $(this).text().toLowerCase();
         return txt.indexOf(v) > -1;
     }).show();    
 })

Answer 3

$(document).ready(function() {

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

//split the current value of searchInput
      var data = this.value.toLowerCase().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.toLowerCase()+"')");
      });
    //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"});

});

我可能會更改過濾器：

      $.each(data, function(i, v) {
          jo = jo.filter(function() {
            return $(this).text().toLowerCase().indexOf(v.toLowerCase()) > -1;
          });
      });
