用JavaScript获取Asp.net服务器端控件CheckBoxList的选中值数组

通用版本（不依赖任何类库）

function  GetCheckBoxListValue(objID)
{
     var  v  =   new  Array();
     var  CheckBoxList  =  document.getElementById(objID);
     if (CheckBoxList.tagName  ==   " TABLE " )
    {
         for (i = 0 ;i < CheckBoxList.rows.length;i ++ )    
             for (j = 0 ;j < CheckBoxList.rows[i].cells.length;j ++ )
   if (CheckBoxList.rows[i].cells[j].childNodes[ 0 ])
                     if (CheckBoxList.rows[i].cells[j].childNodes[ 0 ].checked == true )
                        v.push(CheckBoxList.rows[i].cells[j].childNodes[ 1 ].innerText);
    }
     if (CheckBoxList.tagName  ==   " SPAN " )
    {
         for (i = 0 ;i < CheckBoxList.childNodes.length;i ++ )
             if (CheckBoxList.childNodes[i].tagName  ==   " INPUT " )
                 if (CheckBoxList.childNodes[i].checked == true )
                {
                    i ++ ;
                    v.push(CheckBoxList.childNodes[i].innerText);
                }            
    }
     return  v;
}

Asp.net Ajax  版本（依赖  Asp.net Ajax  类库支持）

function  GetCheckBoxListValue(objID)
{
     var  v  =   new  Array();
     var  CheckBoxList  =  $get(objID);
     if (CheckBoxList.tagName  ==   " TABLE " )
    {
         for (i = 0 ;i < CheckBoxList.rows.length;i ++ )    
             for (j = 0 ;j < CheckBoxList.rows[i].cells.length;j ++ )
                 if (CheckBoxList.rows[i].cells[j].childNodes[ 0 ])
                     if (CheckBoxList.rows[i].cells[j].childNodes[ 0 ].checked == true )
                         Array.add(v,CheckBoxList.rows[i].cells[j].childNodes[ 1 ].innerText);
    }
     if (CheckBoxList.tagName  ==   " SPAN " )
    {
         for (i = 0 ;i < CheckBoxList.childNodes.length;i ++ )
             if (CheckBoxList.childNodes[i].tagName  ==   " INPUT " )
                 if (CheckBoxList.childNodes[i].checked == true )
                {
                    i ++ ;
                    Array.add(v,CheckBoxList.childNodes[i].innerText);
                }            
    }
     return  v;
}
