window.location.href，window.location.replace和window.location.assign之间的区别 [英] Difference between window.location.href, window.location.replace and window.location.assign

问题描述

1. window.location.href =http://example.com有什么区别？ ;


2. window.location.replace（http://example.com）;


3. window.location.assign（http://example.com）;

1. window.location.href="http://example.com";
2. window.location.replace("http://example.com");
3. window.location.assign("http://example.com");

我在许多论坛上看到， window.location.assign（）只是替换当前的会话历史记录，因此返回按钮的浏览器不起作用。但是，我无法再现这一点。

I read in many forums that window.location.assign() just replaces the current session history and hence back button of browser will not function. However, I am not able to reproduce this.

function fnSetVariable() {
    //window.location.href = "http://example.com";
    window.location.replace("http://example.com");
    //window.location.assign("http://example.com");
}

<a onmouseover="fnSetVariable();" 
   href="PageCachingByParam.aspx?id=12" >
   CLICK 
</a>

推荐答案

这些做同样的事情：

window.location.assign(url);
window.location = url;
window.location.href = url;

他们只需导航到新的URL。另一方面，替换方法导航到URL，而不向历史记录添加新记录。

They simply navigate to the new URL. The replace method on the other hand navigates to the URL without adding a new record to the history.

所以，你在这些形式中阅读的内容是不正确的。 分配方法会在历史记录中添加新记录。

So, what you have read in those many forms is not correct. The assign method does add a new record to the history.
