iframe重新加载缓存问题 [英] iframe reload caching issue

问题描述

我在iFrame中执行以下代码：

I am executing the following code in an iFrame:

window.frames[0].location.reload();

重新加载页面，然而，看起来像 SOMETIMES 数据是缓存。我找到了它正在重新加载的URL的来源。我想做的是在URL上附加一个随机数，这样当它重新加载时它是唯一的并且会阻止缓存。

It reloads the page, however, it looks like SOMETIMES the data is cached. I found the source of the URL that it is reloading. What I would like to do is append a random number to the URL so that when it reloads it is unique and will prevent caching.

我怎么能用上面这个码？

How would I do that with the above code?

更新：

我修改了我正在尝试的代码将href设置为我构建的新URL字符串。但是，看起来当我在设置它之后打印出location.href（上面一行）时，我仍然得到旧的location.href。

I have modified the code where I'm attempting to set the href to a new URL string that I built. However, it looks like when I print out the location.href after setting it (the line above), I'm still getting the old location.href.

            window.frames[0].location.href = newIfURL;
            console.log(window.frames[0].location.href);
            window.frames[0].location.href();

我这样做了吗？

推荐答案

类似于：

var fl = window.frames[0].location;
var href = fl.protocol + '//' + fl.host + fl.pathname + '?random=' + Math.random() + fl.hash;
window.frames[0].location.href = href;

当然，如果你需要保留搜索参数，那么你需要添加一些逻辑确定如何添加随机参数。

Of course, if you need to preserve "search" parameters, then you will need to add some logic to determine how to add the random parameter.
