当iframe完成加载外部网站时启用计时器控制 [英] Enable timer control when iframe finishes loading external website

问题描述

在使用C＃的asp.net中，我使用以下代码在按钮点击时将外部网站加载到iframe：

protected void GridView2_RowCommand（object sender，GridViewCommandEventArgs e）

In asp.net with C#, I am loading an external website into an iframe on button click using the following code:
protected void GridView2_RowCommand(object sender, GridViewCommandEventArgs e)

taskpage.Attributes["src"] = "somedynamicurlfromdatabase"; 
taskpage.Visible = true;

我希望启用Asp.net计时器控件当iframe中的网站加载完成时。

注意：按钮，iframe和计时器都在更新面板中。我正在使用Visual Web Developer 2010 Express



我尝试过：



i试图调用iframe并检查其属性但找不到任何解决方案。

I want an Asp.net timer control to be enabled when the website loading in iframe completes.
Note:the button, iframe and timer are in update panel. i am using Visual Web Developer 2010 Express

What I have tried:

i have tried to call the iframe and checked through its properties but could not find any solution.

这是一个例子。



1.将计时器包装在更新面板中

2.不要在元素级别禁用计时器

Here is an example.

1. Wrap the timer in the updatepanel
2. Don't disable the timer at element level

<asp:UpdatePanel ID="UpdatePanel1" runat="server">
        <ContentTemplate>
            <asp:Timer ID="Timer1" runat="server" OnTick="Timer1_Tick" Enabled="true" Interval="10"></asp:Timer>
            <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
        </ContentTemplate>
    </asp:UpdatePanel>

    <iframe id="taskpage" src="http://www.c-sharpcorner.com/blogs/start-stop-asp-net-timer-control-using-javascript1" >
        <p>Your browser does not support iframes.</p>
    </iframe>

3.在页面加载时，停止计时器

4.加载iframe后，启动计时器。您需要测试代码以检测iframe是否完全加载以实现跨浏览器兼容性

3. on page load, stop the timer
4. Once the iframe is loaded, start the timer. You need to test out the code to detect if iframe loaded completely for cross browser compatibility

<script>

（< span class =code-sdkkeyword> document ）。ready（ function （）{
// 停止时间
var timer =

(document).ready(function () { //stop the time var timer =
