I have a page which work like a navigation and a iframe in this page which show the content.
Now there are some situation when the inner page is directly shown in the browser. eg: if somebody types the inner page's url in the browser address bar, the page is displayed in the window.
I want to prevent this.
Better still, I would like to redirect to any other page.
: The window object that contains the frame. :包含框架的窗口对象。 If the the window is the top level window then window.parent refers the window itself. (It is never null.)
: The top level window object, even if the current window is the top level window object. :顶级窗口对象,即使当前窗口是顶级窗口对象。
: The current window object. :当前窗口对象。 (It is a synonym of window.)
So, I'd write my check like this:
if (window.top == window.self) {
window.location = "index.html";
}
Which would be identical to the slightly more ambiguous:
if (window.top == window) {
window.location = "index.html";
}
<script language="Javascript"><!--
if (top.location == self.location) {
top.location = "index.html" // must be viewed in main index
}
//--></script>
modified it from a situation where an an iframe decides to become the main frame.
