How can I go to history.back() when page loads?
提问by sebastian
I have a PHP page that has an error, but if I go back, it works fine. I can't redirect because the page can be accessed from two different places.
我有一个有错误的 PHP 页面，但如果我返回，它工作正常。我无法重定向，因为可以从两个不同的地方访问该页面。

The problem with using the window's onload property is that you do not want the user to wait for the current page to load. Just put this code/HTML at the top of the page right after the opening <head>tag.
使用窗口的 onload 属性的问题是您不希望用户等待当前页面加载。只需将此代码/ HTML 放在页面顶部的开始<head>标记之后即可。
<script type="text/javascript">history.go(-1);</script>

You can use the window.historyobject, like this:
您可以使用window.historyobject，如下所示：
history.back();
//or:
history.go(-1);
