• JQuery实现radio、select、checkbox禁用


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

       <!-- radio的禁用 -->

        var input = $("#appDIV").find("input:radio");
       input.attr("disabled","disabled");
       input.each(function(){
         if($(this).val()==2){
            $(this).attr("checked",true);
         }   
       });

       <!-- checkbox的禁用 -->
       var checkbox = $("#ce").find("input:checkbox");
       checkbox.attr("disabled","disabled");
        checkbox.each(function(){
         if($(this).val()=="Monthly"){
            $(this).attr("checked",true);
         }   
       });

       <!-- select的禁用方法一 -->
       $("#selectItem option:disabled").css('color', '#CCC');
       $('#selectItem').change(function(){
        if(this[this.selectedIndex].disabled){
         this.selectedIndex = this.s||0;
        }else{
         this.s = this.selectedIndex||0;
        }
       });

       <!-- select的禁用方法二 -->

       $("#selectItem").attr("disabled","disabled");

    });

    //以上方法都可以实现

     $(this).find("select,:radio,:checkbox").attr("disabled", "disabled");         这样也可以直接实现!

    </script>

    <body>
    <div id="appDIV">
        <input type="radio" value="1"/>1
        <input type="radio" value="2"/>2
        <input type="radio" value="3"/>3
    </div>
    <div id="sel">
       <select id="selectItem">
        <option value="1" disabled="disabled">Flowers</option>
        <option value="2" disabled="disabled">Gardens</option>
        <option value="3" selected>Trees</option>
       </select>
    </div>
    <div id="ce">
        <input type="checkbox" name="newsletter" value="Daily" />Dairy
        <input type="checkbox" name="newsletter" value="Weekly" />Weekly
        <input type="checkbox" name="newsletter" value="Monthly" />Monthly
    </div>
    </body>
