javascript 很简单的问题....在线等

哦  不能通过id="dlist1_ctl00_dlist2_ctl00_CheckBoxList1_0"和name="dlist1$ctl00$dlist2$ctl00$CheckBoxList1$0"来获取checkbox对象
只能通过<span 来回去<span里面的checkbox对象

解决方案 »

  1.   

    写个偷懒方法，哈注：span 后面必须是 checkbox，否则就要修改js了。

    }

        </script>
    </body>
    </html>
      

  2.   


    <html>
    <head>
    <title> new document </title>
    <script language="javascript">
    function Sel(){
    var obj=document.getElementsByTagName('input');
    for(var i=0;i<obj.length;i++){
    if(obj[i].type="checkbox"){
    obj[i].checked=true;
    }
    }
    }
    </script>
    </head>
    <body>
    <span>
    <input   type="checkbox"   name="table_name"> 
    <input   type="checkbox"   name="table_name"> 
    <input   type="checkbox"  name="table_name"> 
    <input   type="checkbox"   name="table_name"> 
    <INPUT TYPE="button" name="bt1" id="bt1" value="             selectAll            " onclick="Sel()">
    </span>
    </body>
    </html>
      

  3.   

    <script language="javascript" type="text/javascript" charset="utf-8">
    var checkboxs = document.getElementByTagName("input");
    for (var i=0;i<checkboxs.lenght;i++)
    {
    if (checkboxs[i].type.toLowerCase() == "checkbox") {checkboxs[i].checked = true;}
    } 
    </script>
      

  4.   

    因为一部分input的信息一定要写在SPAN里面,所以只能通过SPAN获取
