在源页面中获取iframe ID [英] Get iframe id in source page

问题描述

我有两个页面，一个是主页面，另一个是常见页面。在主页面中，我还有两个小部件和包含iframe的小部件，其中包含公共页面的源代码。所有具有相同公共页面的小部件，当我点击iframe的按钮时，它会转到按钮点击事件后面的公共页面代码。在那里我想要iframe的id，其中iframe初始化了常用页面中的按钮点击。我可以得到它吗？请帮忙。



我的尝试：



主页：

< div> 
< iframe id =widget1src =commonpage.aspx>< / iframe> 
< / div> 
 
< div> 
< iframe id =widget2src =commonpage.aspx>< / iframe> 
< / div> 

常用页面：

< form runat =server> 
< div> 
< p>测试页< / p> 
< asp：Button ID =Button1runat =serveronclick =Button1_ClickText =TestButton>< / asp：Button> 
< div> 
< form> 

代码落后：

 protected void Button1_Click（对象发件人，EventArgs e）
 {
 //这里我想要iframe ID。哪一个发起了事件
} 

解决方案

试试这个



在Common Page ASPX中：

编写一个javascript函数来获取Iframe ID并将其存储在隐藏字段中

  function  SetWidgetName（）{
  document  .getElementById（' <％= hdnWidgetName.ID％>'）。value =  window  .frameElement.id 
} 
 

< pre lang =ASP.NET> < asp：按钮 ID = Button1 OnClientClick = SetWidgetName（）; runat = 服务器 OnClick = Button1_Click 文字 = TestButton > < / asp：按钮 >
< asp：HiddenField ID = hdnWidgetName runat = server / >

代码背后：

 受保护 < span class =code-keyword> void  Button1_Click（ object  sender，EventArgs e）
 {
  string  widgetName = hdnWidgetName.Value;  //  获取iframe ID  
} 

Hi,
I have two pages, one is main page and another one is a common page. In the main page i have two more widgets and the widgets containing iframe with source of common page. all widgets having the same common page, when i click a button of iframe its went to common page code behind button click event. There I want the id of iframe, in which iframe initialized the button click in the common page.how can i get it? please help.

What I have tried:

main page:

<div>
    <iframe id="widget1" src="commonpage.aspx"></iframe>
</div>

<div>
<iframe id="widget2" src="commonpage.aspx"></iframe>
</div>

common page:

<form  runat="server">
  <div>
      <p>Test page</p>
      <asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="TestButton"></asp:Button>
  <div>
<form>

code behind:

protected void Button1_Click(object sender,EventArgs e)
{
           // here i want the iframe id. which one initiated the event
}

解决方案

Try this

In Common Page ASPX:
Write a javascript function to get the Iframe ID and store it in a hidden field as

function SetWidgetName() {
           document.getElementById('<%= hdnWidgetName.ID%>').value = window.frameElement.id
     }

<asp:Button ID="Button1"  OnClientClick="SetWidgetName();" runat="server" OnClick="Button1_Click" Text="TestButton"></asp:Button>
<asp:HiddenField ID="hdnWidgetName" runat="server"  />

Code behind:

protected void Button1_Click(object sender, EventArgs e)
      {
          string widgetName = hdnWidgetName.Value; // get the Iframe ID
      }
