JS浏览器对象-History对象

 

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>uvi</title>
     <link rel="stylesheet" href="style.css" type="text/css">
</head>
<body>
   <button id="btn" onclick="goceshi()">按钮</buton>
   <script>
      function goceshi(){
          history.back();
      }
   </script>
   
</body>
</html>

 

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>uvi</title>
     <link rel="stylesheet" href="style.css" type="text/css">
</head>
<body>
   <a href="index9.html">跳转到index.html页面</a>
   <button id="btn" onclick="">按钮</button>
   <script>
      function goindex9(){
          history.forward();
      }
   </script>
</body>
</html>

 

下面的例子演示：点击ceshi.html的链接跳转到index10.html登陆页面，然后输入正确的用户名（"hello"）后又返回到之前的页面ceshi.html

                       即利用了history.go(-1)

ceshi.html

 1 <!DOCTYPE html>
 2 <html>
 3 <head>
 4 <meta charset="UTF-8">
 5 <title>uvi</title>
 6      <link rel="stylesheet" href="style.css" type="text/css">
 7 </head>
 8 <body>
 9    <a href="index10.html">跳转到index.html页面</a>
10    
11 </body>
12 </html>

 

index10.html

 1 <!DOCTYPE html>
 2 <html>
 3 <head>
 4 <meta charset="UTF-8">
 5 <title>uvi</title>
 6      <link rel="stylesheet" href="style.css" type="text/css">
 7 </head>
 8 <body>
 9    <form>
10    <input type="text" id="username">
11    </form>
12    <button id="btn" onclick="safe()">按钮</button>
13    <script>
14       function safe(){
15           var name = document.getElementById("username").value;
16           alert(username);
17           if(name=="hello"){
18               history.go(-1);//回到之前的界面
19           }else{
20               alert("输入错误");
21           }
22       }
23    </script>
24    
25 </body>
26 </html>
