jquery 选中

<TD style="WHITE-SPACE: nowrap"><INPUT id=tveen3CheckBox title=区间1 type=checkbox name=tveen3CheckBox><A id=tveet3 class=tvee_0 href="javascript:SelectTreeNode(this, '132','0','区间1')">区间1</A></TD>       function SelectTreeNode(obj,nid,deph,nodename)
    {
//如何将该A 标签平级的checkbox勾选上，下面这种方式不行啊
        $(obj.parentElement).find(':checkbox').checked=true;
      
    }

解决方案 »

  1.   

    这个里面只截取了一个，有N个，怎么能传ID
      

  2.   

    $(obj).parent().find("input [type=checkBox]")
      

  3.   


    function SelectTreeNode(obj,nid,deph,nodename)
      {
    //如何将该A 标签平级的checkbox勾选上，下面这种方式不行啊
        $(obj).parent().find(':checkbox').attr("checked",true);
      }
      

  4.   

    $(obj).prev()[0].checked=true;
    试试
      

  5.   

    $(this).prev("input[type=checkbox]").attr("checked")OR$(this).parent("td").find("inpu[type=checkbx]").attr("checked")
      

  6.   

    function SelectTreeNode(obj,nid,deph,nodename)
      {
    //如何将该A 标签平级的checkbox勾选上，下面这种方式不行啊
        $(obj).parent().find(':checkbox').attr("checked","checked");
      }
      

  7.   

    都不可以的，上面的方法我在一个测试的html都试了，$(obj).prev()都找不到对象，$(obj).parent("td")都找不到<html >

  8.   

    function SelectTreeNode(that)
            {
           var c= $(that).siblings("input");
           c.attr("checked",!c.attr("checked"));
            return false;
            }
