页面更改后 Javascript 代码不执行

Question

这个问题已经有答案了:

Is there a way to have an onload callback after changing window.location.href? (3 个回答)

已关闭 5 年前。

所以，我正在尝试运行这段代码

document.location = "https://stackoverflow.com/questions/ask";
document.onload = function(){document.getElementById("title").value="My question";};

但事实证明我的函数没有运行该函数。您可以通过执行以下操作来观察这一点

document.location = "https://stackoverflow.com/questions/ask";
document.onload = function(){document.getElementById("title").value="My question";alert('Hi');};

我的问题是，我做错了什么？为什么函数不运行？

No, you cannot do it the way you want. Loading a new page closes the current document and starts loading a new document. Any code in your current document will no longer be active when the new page starts to load. - Source: Answer by jfriend00
