嵌套在gridview中checkbox实现单选、全选功能（js实现）

1.html

//实现单选功能
  <script type="text/javascript"> 

var ClickNum=0;//判断同一checkbox连续点击次数

   var PreCheckboxID="";//记录点击checkbox的ID

   //listId为控制checkbox的范围

   //SelectRadio是点击checkbox自己

function SignCheck(listId,SelectCheckBox)

{

   ///判断是否连击同一个checkbox

    if(PreCheckboxID==SelectCheckBox.id)

    {

        ClickNum = ClickNum + 1;

    }

    else

    {

        PreCheckboxID = SelectCheckBox.id;

        ClickNum = 0;

    }

    //找到控制范围

   var GridViewableSearchList=document .getElementById(listId);

   //找到控制范围下所有input

   var objs=GridViewableSearchList.getElementsByTagName("input");

   //找到控制范围下所有checkbox并都变为false

    for(var i = 0; i < objs.length; i++) 

    {

        if(objs[i].type.toLowerCase() == "checkbox" )

        objs[i].checked = false;

    }

    var SelectCheckBoxId=SelectCheckBox.id; 

    //如果连击次数为奇次checked为true偶次为false

    if(ClickNum%2!=1)

    {

       document.getElementById(SelectCheckBoxId).checked = true;

    }

    else

    {

        document.getElementById(SelectCheckBoxId).checked = false;

    }

}

//全选、全不选功能实现
function GetAllCheckBox(CheckAll)
{
var items=document.getElementsByTagName("input");
for(var i=0;i<items.length;i++)
{
if(items[i].type=="checkbox")
{

items[i].checked=CheckAll.checked;
}

}
}
    </script>
