Why Some Sites not opening in Pop Window?_问答_开发者

I have an html page. On that page I want to open popup window. I have a link on which I have to click & open new pop up. But, it is not a new browser window. It is AJAX based popup.

I do have used Queness popup & YUI dialog popup.

Now, in that window I want to show an iframe which will display page related to link I have clicked. But, for security point of view, iFrame is not showing that page on popup window, but the control of the page transfers to that page & page gets redirected to that page.

How to make popup steady to show that window ?

Here, I am showing YUI dialog code :

<h1>Dialog Quickstart Example</h1>

<div class="exampleIntro">
    <p>The Dialog Control is designed to allow you to retrieve information from the user and make use of that information within the page &mdash; whether interally to the page or by sending the information to the server via form post or XMLHttpRequest.  This example shows how to do the latter.  Click the button to show the Dialog instance and its form fields; fill out the form; submit the form.  Dialog will automatically use the YUI Connection Manager to send the data via XMLHttpRequest to the server and will then echo that data back to you on the page.</p>

This is dialog.html page. But,while loading it, it will transfer to http://stackoverflow.com. You can change this url from src property of iframe.

You can only do an XMLHTTP request to a page in the same domain. The browser doesn't allow cross domain requests.

To do a cross domain request you need a server page in your domain that can work as a proxy and do the request for you.

Plenty of page authors do not wish their sites to be displayed in frames on other people's sites and take steps to avoid it.

You need to bite the bullet, accept their wishes, and stop trying to frame third party content without permission.
