问题描述

我的主要目标是:

转到我的应用程序,在新标签页面中打开链接,在新标签页中创建内容并发送活动到父母主要标签刷新。

我已经学会了2种不能完全满足我需要的技术:

I have learned 2 techniques that doesn't do exactly what I need:


  1. postMessage - 据我所知只在iframe而不是在标签上工作

  2. window.opener - 仅适用于窗口。 open(url)只打开新窗口而不是新标签。

如何使用子项将事件传递给父级标签?我很高兴在父母和孩子的javascript代码的具体示例。它应该适用于跨域(例如:www.mydomain.com和bills.mydomain.com)。

How can I pass an event from the child to the parent using tabs? I'd be happy for a specific example for javascript code in the parent and the child. It should work for cross-domain (for example: www.mydomain.com and bills.mydomain.com).

我缺少一个jQuery解决方案吗?

Is there a a jQuery solution I am missing?

推荐答案

以下适用于我的chrome,firefox,即(没有测试更多浏览器)

The following works for me in chrome, firefox, ie(didn't test more browsers)

假设3个文件


  1. www.mydomain.com/parent.html )包含带有链接的主要文档的页面

  2. bills.mydomain.com/child.html )将由链接

  3. www.mydomain.com/dispatcher.html )稍后解释

  1. (www.mydomain.com/parent.html)the page that contains the 'main'-document with the link
  2. (bills.mydomain.com/child.html)the page that will be opened by the link
  3. (www.mydomain.com/dispatcher.html)explained later

首先将所有3个文档的域属性设置为mydomain.com

at first set the domain-property of all 3 documents to mydomain.com

<script>
document.domain="mydomain.com";
</script>

创建一个隐藏的iframe,其名称属性为例如hiddenframe。还要创建一些稍后可能收到回复的函数。

in parent.html create a hidden iframe with a name-property of e.g. "hiddenframe". Also create some function that may later receive a response.

parent.html现在应该如下所示:

parent.html should now look like this:

<script>
document.domain="mydomain.com";
function fx(msg)//receives the response
{
  alert(msg)
}
</script>
<iframe name="hiddenframe" style="display:none"></iframe>
<a href="http://bills.mydomain.com/child.html" target="_blank">click</a>






在child.html中,您现在可以使用将文档加载到parent.html内隐藏的iframe中


In child.html you'll now be able to load a document into the hidden iframe inside parent.html

<script>
document.domain="mydomain.com";
window.open('http://www.mydomain.com/dispatcher.html','hiddenframe');
</script>

(面对使用 window.open时不要混淆()在这里,不会打开新窗口,页面将被加载到parent.html中的iframe中)

(don't be confused in face of the use of window.open() here, there will not open a new window, the page will be loaded into the iframe in parent.html)

在dispatcher.html中,您现在可以调用parent.html内的函数

In dispatcher.html you now may call the function inside parent.html

<script>
document.domain="mydomain.com";
parent.fx('you just got some response');
</script>






当你只需要重装时parent.html它有点容易。

再次在parent.html和child.html中设置document.domain-property(您不需要parent.html中的iframe和dispatcher.html)

Again set the document.domain-property in parent.html and child.html(you don't need the iframe in parent.html and the dispatcher.html)

在parent.html中还设置了窗口的name-property,例如

In parent.html also set the name-property of the window, e.g.

<script>
  window.name="parentTab";
</script>

在child.html中,您现在可以访问 parentTab -window(tab)

In child.html you now may access the parentTab-window(tab)

<script>
    document.domain="mydomain.com";
    window.open('http://www.mydomain.com/parent.html','parentTab');
</script>

...或者只是使用parentTarget作为子项中链接或表单的target-property。 html

...or simply use "parentTarget" as target-property of a link or form in child.html
