河北重大需求第八稿细节处理-灰度实现

第八稿在填报时需要实现填完一个空再继续填下一个空

主要就是对于灰度的调制

     <html>  
    <head>  
    <meta http-equiv="Content-Type" content="text/html; charset=gb2312">  
    <title>新建网页 1</title>  
    </head>  
    <body>  
    <form name="form0" onsubmit="if (this.txt.value=='预设值是灰色'){this.txt.value='';alert('txt.value='+this.txt.value);}">  
    txt:<input id="txt"  name="txt" type="text" value="预设值是灰色" style="color:#ddd" onfocus="if (this.value=='预设值是灰色')this.value=''" onblur="if (this.value=='')this.value='预设值是灰色'">  
    <input type="submit" value="OK"></form>  
    </body>  
      
    </html>

然后就是在function中设置动作就好

 <script type="text/javascript">

     $(function(){

            $('#cc').combobox({    

                 required:true,    

                 multiple:true,

                 disabled:true，

                    editable:flase

           });  

      });

</script>
