分享关于弹出子页面参照的问题？
我在项目中使用了较多的父页面弹出子页面，选择值后返回刷新父页面.查了不少资料，都是用JS控制，现在的问题是我的子页面全部是treeview,gridview之类的从数据库提取的动态提取的数据，在JS中如何访问这些服务器端的控件取得选择的值呢？还有其他方法没？TKS

不懂的可以参考DHTML

<script type="text/javascript">
<!--
function selectCode()
{
var s=document.getElementById("TextBox1").value;
window.returnValue=s;
window.close();
}
-->
</script>
s就是返回值了
在父页面这样调用:
var returnvalue = window.showModalDialog(url,window);
alert(returnvalue);//returnvalue 就是s了
window.returnValue还可以值数组
var returnvalue = window.showModalDialog(url,window)
这里的returnvalue 就是数组通过returnvalue[0] returnvalue[1]...来获取值

dt.rows(i).cells(j)
一般都是这样,有问题去查dhmtl

直接点，子页面这个方法如何改下
<script type="text/javascript">
<!--
function selectCode()
{
var s=document.getElementById("TextBox1").value;
window.returnValue=s;
window.close();
}
-->
</script>

没太明白你要取的什么值啊？
知道了id或name不就行了吗，GridVeiw的话设个模板列把这一行要用到的值都绑定在这列你添加的控件value上，用name取对应的值就行了。
treeview也差不多

右键查看一下生成的html代码，就可以知道生成的Treeview或Gridview的Dom结构了
再去用js操作就快捷了
