.net后台的函数怎么调用JS里的变量值啊?
后台有一个函数,我想把js里的变量值传过来,怎么传阿?
代码如下:JS代码:
function openDiv3(id)
    {
        var txt_ID=id.id;
        sWidth=document.body.offsetWidth;
        sHeight=screen.height;
        
        var bgObj=document.getElementById('divBG3');
        bgObj.style.filter="progid:DXImageTransform.Microsoft.Alpha(style=2,opacity=25,finishOpacity=75";
        bgObj.style.opacity="0.5";
        bgObj.style.width = sWidth;
        bgObj.style.height = sHeight;
        bgObj.style.display="inline";
        
        var bgObjCtrl = document.getElementById('divCtrl3');
        bgObjCtrl.style.width = sWidth;
        bgObjCtrl.style.display="inline";
        document.all("objb4").disabled=true;
        
    }
txt_ID就是我要的变量
后台有一个函数 getinfo 我怎么得到txt_ID的值呢?

那你把这个值 放在隐藏域中!
   把隐藏域 加个RUNAT= SERVER 不就可以取到了吗?
