使用Javascript在帧之间传递数据 [英] Passing data between frames with Javascript

问题描述

我在 http://ryanmalin.co.uk/frames/

如果按添加，它会将左边框架中的表格数据粘贴到右边框架中。

If you press "add" it will paste the form data from the left frame into the right frame.

当我将右框架URL更改为另一个域的URL时，Firebug会抛出错误，但它不起作用。显示的错误是：

When I change the right frames URL to that of another domain Firebug throws an error and it doesn't work. The error shown is:

错误：访问属性'document'的权限被拒绝

Error: Permission denied to access property 'document'

是否可以使用frames / javascript将数据从我的域中的一个预先填写的表单复制到另一个域上的表单？

Is it possible to copy data from one pre-filled form on my domain to a form on another domain using frames/javascript?

我认为这是一种内置于浏览器或网站的反垃圾邮件措施，但如果可能的话，我需要绕过它。为了通过我的包裹递送公司发送客户订单，我一直在两个浏览器标签之间逐个复制每个地址字段 - 现在订单正在增加我需要加快这个过程，但是快递还没有办法发送所有的日子一次订购详细信息。

I believe it is an anti-spam measure built into browsers or websites but if possible I need to get around it. To send customer orders through my parcel delivery company I have been copying over each address field one by one between two browser tabs - now that orders are increasing I need to speed this process up, however the courier doesn't yet have a way of sending all of the days order details at once.

我可以编写获取左框架订单详细信息所需的PHP但不想浪费时间，如果不可能我做了什么。

I can write the PHP needed to grab the order details for the left frame but don't want to waste time if its impossible to do what Im after.

非常感谢：）

推荐答案

有关帧间安全性如何工作的说明，请参阅同源策略。简而言之，出于安全原因，在不同域上的帧之间允许的通信很少。你不能在不同域的帧之间进行任何直接的Javascript调用。

See the "Same Origin Policy" for a description of how inter frame security works. In a nutshell, there is very little communication allowed between frames on a different domain for security reasons. You cannot make any direct Javascript calls between frames on different domains.

HTML5有一个新的消息传递系统，可以安全地在不同的协作帧之间传递数据（而不是直接的JS调用）域。请参见此处和这里描述了HTML5消息传递的工作原理。

HTML5 has a new messaging system that can safely communicate data (not direct JS calls) between cooperating frames in different domains. See here and here for a description of how the HTML5 messaging works.
