When I was preparing the interview questions, I encountered a page refresh, so I sorted it out and searched online. There were about eight methods. However, when I tested it, I encountered several problems. I would like to share with you:

First prepare a test page:

<!--html代码--> 
<h1 id="test">页面刷新</h1>
<button onclick="fresh()">刷新</button

Copy after login

//script
var h1 = document.getElementById(&#39;test&#39;);
function test(){
     h1.style.color = "red";
     h1.innerText = "我变化了";
}
setInterval(test, 1000);

Copy after login

Preparation work is completed, start the page refresh method:

Five methods that can be used normally:

 //第一种方法
function fresh(){
       window.location.reload();//强迫浏览器刷新当前页面，默认参数为false，表示从客户端缓存里取当前页。如果指定为true,则以GET方式从服务端取最新的页面,相当于客户端点击F5。
}

Copy after login

 //第二种方法
 function fresh(){
      history.go(0);
}

Copy after login

 //第三种方法
 function fresh(){
       location = location;
 }

Copy after login

 //第四种方法
 function fresh(){
       location.assign(location);//assign()方法加载一个新的文档。
 }

Copy after login

 //第五种方法
 function fresh(){
     location.replace(location);//通过指定URL替换当前缓存在历史里（客户端）的项目，所以使用replace方法之后，不能通过“前进”和“后退”来访问已经被替换的URL。
 }

Copy after login

2. Two methods that can only be executed in IE:

 //第六种方法
 function fresh(){
       document.execCommand(&#39;Refresh&#39;);//是只有IE提供的方法，叫浏览器方法。
 }

Copy after login

 //第七种方法
 function fresh(){
       window.navigate(location);//只在ie可以执行，不适用于火狐等其他浏览器。
 }

Copy after login

3. It is easy to find online, but Personally I think this is the wrong method:

 //错误方法
 function fresh(){
       document.URL=location.href;//错误用法，document.URL只能读不能写
 }

Copy after login

But there is also an alternative method:

//第八种方法
//window.location.href和document.location.href可以被赋值，然后跳转到其它页面
//一个窗口下只有一个window.location.href，但是可能有多个document.URL、document.location.href
function fresh(){
      document.location.href = location.href;
      //可以使用，document表示的是一个文档对象   
}

Copy after login

 //第九种方法（与第八种方法是一类）
 function fresh(){
      window.location.href = location.href;//可以使用，window表示的是一个窗口对象
 }

Copy after login
