iframe: How can we change iframe src from inside iframe itself?
提问by user3137239
I know there are question have been asked around resembling to this one, but still I am not getting proper concept of this. I am currently loading an iframe through javascript in following manner:
我知道有人问过类似这个的问题，但我仍然没有得到正确的概念。我目前正在以下列方式通过 javascript 加载 iframe：
jQuery('.out-div-login').html("<iframe id='parent' frameBorder='0' width='320' height='500' src='"+_url+"'></iframe>");
Which is working fine. (its cross domain). After loading my application inside given iframe, I want to come back to original state where .out-div-loginwas loading iframe into parent html.
From outside of iframe I can do this by accessing iframe using its idattribute, but not from the inside. Is there any way I can reload the iframe by giving its src again ? or by above code but from inside the iframe ? Thanks.
Update
I have tried below code without any success as of now:
哪个工作正常。（它的跨域）。在给定的 iframe 中加载我的应用程序后，我想回到.out-div-login将 iframe 加载到父 html 的原始状态。
从 iframe 外部，我可以通过使用 iframe 的id属性访问 iframe 来做到这一点，但不能从内部访问。有什么办法可以通过再次提供它的 src 来重新加载 iframe 吗？或者通过上面的代码但是从 iframe 内部？谢谢。
更新
我已经尝试了以下代码，但目前没有任何成功：
var ifr = $('iframe[id="parent"]');
from one of js file inside iframewith id parent. when I do console.log(ifr)it gives in firebug something like this Object[]instead of <iframe id="parent">
来自其中一个iframeid的 js 文件parent。当我这样做时，console.log(ifr)它会给萤火虫这样的东西Object[]而不是<iframe id="parent">

You should use location.hrefinside the iframe. That should work. set location.href in the iframe to your new location.
您应该location.href在 iframe 内使用。那应该有效。将 iframe 中的 location.href 设置为您的新位置。

The url query string (?xxx) should also be kept in the new url, so the whole solution should be:
url查询字符串（？xxx）也应该保留在新的url中，所以整个解决方案应该是：
location.href = "new_link_url" + location.search;
