如何使用javascript传递值到iFrame？ [英] How can I pass value to iFrame with javascript?

问题描述

我在我的页面和onClick事件中打开一个iFrame尝试向iframe的文本框发送一个值

I opened an iFrame in my page and onClick event try to send a value to the textbox of the iframe

这是我的javascript代码

This is my javascript code

<script type="text/javascript">
    function TextToFrame()
    {   
     var frame = frames['frame1'];
     frame.document.getElementById("u").value = "wallace";
    }
</script>

IFrame加载页面，但是当我单击按钮时，它不发送任何值。
它刷新主页和iFrame

IFrame loads the page but when I click the Button , it doesn't send any value. It refreshes the main page and iFrame

<asp:Button ID="Button1" runat="server" OnClientClick="TextToFrame();" Text="Send Value" />  

<IFRAME id="frame1" name="frame1" src="http://tweakers.net/my.tnet/login?location=http%3A%2F%2Ftweakers.net%2F" width=500px height=500px  runat="server">

我做错了什么？
任何帮助感谢

What am I doing wrong? any help appreciated

推荐答案

我不认为你可以修改来自不同域的iframe中的HTML。您可以将iframe来源更改为以下内容：

I don't think you can modify the HTML in an iframe from a different domain. You might be able to change the iframe source to something like:

http://tweakers.net/my.tnet/login?u=wallace

但网站应该给你这样的选项。

but the site should give you an option like that.
