自动完成焦点无法正常工作

Question

I have an autocomplete input box. I want to display "x" link when I start to write something into input box. But it doesn't work. I don't know what is the mistake. Here are my codes and jsfiddle below.

 <style>
 .icon-removeSearchItem{
   position: absolute;
   margin-left: -16px;
   display:none;
 }
</style>

 <link rel="stylesheet" href="//code.jquery.com/ui/1.11.4/themes/smoothness/jquery-ui.css">
 <script src="//code.jquery.com/ui/1.11.4/jquery-ui.js"></script>
 <script>
  $(function() {
    var availableTags = [
    "ActionScript",
    "AppleScript",
    "Asp",
    "Ruby",
    "Scala",
    "Scheme"
  ];
  $( "#tags" ).autocomplete({
    source: availableTags
  });
});
</script>

<script>
$( document ).ready(function() {
   $('input').focus(function(){
   if(this.value==this.defaultValue)this.value='';
   var value = $(this).val();
   if($('input').val().trim().length > 0 && value != "Add Comment"){
       $(".icon-removeSearchItem").show();
   }
  });
});
</script>

您的问题尚不清楚。如果您说要显示搜索值的限制数量，则可以使用以下代码：-$（“ #search”）.autocomplete（{来源：tags.slice（0，limit ），
