浏览器后退作用于嵌套的iframe页面本身之前 - 有没有办法避免呢？ [英] browser back acts on nested iframe before the page itself - is there a way to avoid it?

问题描述

我有一些Ajax和JavaScript的大量装载动态数据的页面。

I have a page with dynamic data loaded by some ajax and lots of javascript.

页包含一个列表，用户可以选择和每个所选择的值加载新数据到页。

the page contains a list from which the user can choose and each selected value loads new data to the page.

其中的一个数据项是提供给一个iframe的URL。

One of these data items is a url provided to an iframe.

我用 jQuery的烧烤：后退按钮和放大器;查询库来模拟浏览器回的行为。

I use jQuery BBQ: Back Button & Query Library to simulate the browser-back behavior.

一切运作良好，除了当我点击后退按钮，第一次的iframe可以追溯到它的previous位置，然后我需要回去再次单击使页面回去的事实。

All works well besides the fact that when i click the back button for the first time the iframe goes back to its previous location and then I need to click back again to make the page go back.

有没有一种方法来禁用的iframe的背面行为？

Is there a way to disable the iframe's back behavior?

推荐答案

我已经找到了答案，我的问题想这可能是对别人有用的在那里。

I've found the answer to my problem guess it could be useful for others out there.

该问题是与我分配了新的URL到我的iframe的方式，我用jQuery的所以它看起来是这样的：

The problem was with the way i assigned new URLs to my Iframe, i used Jquery so it looked something like that:

$('#myIFrame').attr('src',newUrl);

当以这种方式指定的URL它增加了一个新条目访问的URL来回到浏览器的列表。
这是不是所需的行为，因此一些谷歌上搜索，我发现，你可以不将其加入了背列表指定一​​个新的URL的iframe对象之后，它看起来就像是：

When assigning the URL in that manner it adds a new entry to the browser's list of visited URLs to go back to.
That wasn't the desired behavior, so after some googling i found that you can assign a new URL to an Iframe object without adding it to the 'back-list', it looks like that:

var frame = $('#myIFrame')[0];  
frame.contentWindow.location.replace(newUrl);

这样我后退按钮行为完全符合预期。

This way my back button behave exactly as expected.

顺便说一句，我得到了我的回答从<一个href="http://www.ozzu.com/programming-forum/ignoring-iframes-with-javascript-history-t67189.html">here.
