控件的disabled

    <script type="text/javascript">
        $(document).ready( function(){
            $("#btn1").click( function(){
                $("#txt1").attr("disabled","disabled");
            });
        });
    </script>这样可以让控件变为不可用，那怎么让它可用啊。

解决方案 »

  1.   

     $("#txt").attr("disabled","");
     $("#txt").removeAttr("disabled")
    都可以 。
      

  2.   

    $("#txt").attr("disabled","");
    $("#txt").removeAttr("disabled");
    都可以 。
      

  3.   

    $("#txt").attr("disabled","");
    $("#txt").removeAttr("disabled");
    都可以 。
      

  4.   

     $("#txt1").attr("disabled","");
    这样应该就可用了吧。
    或者你 $("#txt1").attr("disabled",false);
    也可用吧。
      

  5.   

    同ls
    只要把disabled设置为空或设置为false就行了。
    $("#txt1").attr("disabled","");

    我这边怎么没效果呢，老师。
      

  15.   

     $("txt1")
    =》
     $("#txt1")
      

  16.   

    顶下，用这个 $("txt1").attr("enabled","true");也行
