js遍历连接、文本框、表格

遍历所有链接,并设置为不可见.
 var a = document.getElementsByTagName("A");  
        for(var i=0;i<a.length;i++)  
        {  
            if(a[i].name.indexOf('IDView') != -1)
                a[i].style.display = 'none';
        }

遍历所有文本框.

var list=document.getElementsByTagName("input");

for(var i=0;i<list.length && list[i];i++)
{
      //判断是否为文本框
      if(list[i].type=="text")  
      {
         for(var j=0;j<86;j++)
             {
                 if(list[i].id == JsDispatch.value[0][j])
                 {
                   list[i].value = JsDispatch.value[1][j];
                 }
             }
      }
}
遍历表格,DataGrid,GridView

 function getPreTicket()
    {
        var _table = document.getElementById("gvTicketList"); //获取表格gvTicketList为GivView控件名;
        var _trs = _table.all.tags('tr');//获取所有行;
        for(var i=0;i < _trs.length ; i++)
        {
            if(_trs[i].id.indexOf(__currentTicketID)!=-1) //当前行,是否有绑定表的主键,
            {
                i--;//切换到上行
                if(_trs[i]!=null && _trs[i].id!="")
                {
                    var _s1 ="gvTicketList";
                    BindData( _trs[i].id.substring(_s1.length+1) );//把这一个行ID传给其它函数
                }
                else
                {
                    alert("This is the first record of the current page!");
                    document.getElementById("aPreTicket").style.disbaled =true;
                    break;
                }
            }
        }
 }
