JavaScript的;从其他帧中访问框架集框架 [英] Javascript; Accessing frameset frames from within other frames

问题描述

我有一个使用框架集的系统，在框架集框架内有一些调用，如;

I have a system in place which uses a frameset, within the frameset frames there are some calls like;

top.frame1.location = "newlocation"; 

和

top.frame2.afunction(); 

但是我正在更新系统，现在框架集位于iframe内部，显然所有的top.frame.whatever调用不再起作用。现在我正试图找到一个不涉及改变顶部的解决方案。在大量运行各种功能的页面中。

However I am updating the system, and now the frameset resides inside an iframe, so obviously all of the top.frame.whatever calls no longer work. Now I'm trying to find a solution which doesn't involve changing the "top." in the ton of pages that run various functions.

我在最顶层的网页上尝试过这样的事情;

I've tried in the top most page doing something like this;

frame1 = $('#containerframe').contents().find('#frame1');

但这似乎不起作用，它只是说top.frame1.document在尝试时是未定义的访问该文件。

But that doesn't seem to work, it just says top.frame1.document is undefined when trying to access the document.

任何建议都会很酷：）

推荐答案

您使用jQuery集覆盖了 top.frame1 中的值，该jQuery集与默认值（这是一个窗口对象）不是同一个对象，这就是为什么你是得到未定义错误 - jQuery集没有 文档属性。

You are overwriting the value in top.frame1 with a jQuery set, which is NOT the same object as the default (which is a window object) which is why you are getting the "undefined" error - a jQuery set doesn't have a document property.

如果你想修改这个而不用更改你对top.frame1的所有引用，那么你有几个选择。假设 #containerframe 是你的iframe，我认为这样可行

If you want to fix this without changing all your references to top.frame1, then you have a couple choices. Assuming #containerframe is your iframe, I think this will work

在你父母的页面中

frame1 = self.frames.containerframe.frames.frame1;

编辑

frames 收集 name 属性，所以请确保你的iframe看起来像这样

EDIT

The frames collection works off of name attributes, so make sure your iframe looks like this

<iframe id="containerframe" name="containerframe" />
