IFrame和父窗口 [英] IFrame and Parent window

问题描述

iframe可以在父页面上安装cookie或会话吗？如何在不使用Ajax的情况下在iframe中获取iframe的值？我试图将id值从iframe传递到父页面，然后提交它。

Can an iframe install a cookie or session on the parent page? How do i get value in an iframe to the parent page without using Ajax? I am trying to pass an Id value from the iframe to the parent page and then submit it.

推荐答案

在iframe中，您可以使用 parent.document 。如果你的父窗口中有一个输入字段并想在不使用AJAX的情况下在其上设置一个值，你应该只需使用JavaScript就可以执行以下操作：

From within your iframe, you can reference the parent document using parent.document. If you had an input field in your parent window and wanted to set a value on it without using AJAX, you should simply be able to do the following using JavaScript:

parent.document.getElementById('myInputId').value = 'some value';
parent.document.getElementById('yourFormId').submit();

您也可以在父页面中调用函数：

You can call functions in your parent page as well:

parent.someFunction();

我不确定从子框架操纵父级的cookie，但是你的帖子看起来您需要做的就是存储并提交一个值。只用PHP就无法做到这一点。

I'm not sure about manipulating a parent's cookie(s) from a child frame, but your post it seems like all you need to do is store and submit a value. You won't be able to do it with just PHP.
