使用TreeView填充iframe src(asp.net，javascript) [英] populate iframe src using TreeView (asp.net, javascript)
问题描述
我的页面包含:
1-一个从数据库中获取数据的asp:treeview节点(item_Name，item_Id).
2- iframe，带有指向带有参数
的外部页面的链接
用户应选择一个项目(树节点)，以根据选定的节点值(item_id)动态填充iframe源(src).
iframe:
My page contains:
1- An asp:treeview nodes (item_Name,item_Id) getting data from database.
2- iframe with a link to an external page with a parameter
The user should select an item (tree node) to populate the iframe source(src) dynamically according to the selected node value (item_id).
the iframe:
<iframe id="myFrame" runat="server"
frameborder="0" marginwidth="0" marginheight="0" border="0" src="http://www.mynextwebsite.com/default.aspx" scrolling="yes" ></iframe>
我创建了javascript函数来更改iframe src链接.如下:
setframe()脚本:
I created javascript function to change the iframe src link .. as follows:
setframe() script:
function setFrameUrl(id){
newUrl = 'http://www.mynextwebsite.com/default.aspx?mykey='+ id
document.getElementById('myFrame').src = newUrl;}
在页面加载时将属性添加到treeview:
Attribute added to treeview at pageload :
treeView1.Attributes.Add("SelectedNodeChanged","return setFrameUrl('" +treeView1.ClientID + "')");
我的问题< iframe>不随选择而改变！
my problem the <iframe> not changing with a selection!
what is the best way to do it?
推荐答案
我认为您正在混淆dom元素事件和.net事件. SelectedNodeChanged是一个asp.net服务器端事件，您可以在回发期间进行处理.
看一下这篇文章: ASP.NET TreeView Control&客户浏览器 [
I think you''re confusing dom element events and .net events. SelectedNodeChanged is an asp.net server side event that you can handle when during a postback.
Have a look at this article: ASP.NET TreeView Control & the Client''s Browser[^]
