H5的storage(sessionstorage&localStorage)简单存储删除
众所周知，H5的storage有sessionstorage&localStorage，其中他们的共同特点是API相同
下面直接上代码，storage中的存储与删除:
<!DOCTYPE html> <html> <head lang="en"> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>H5的storage</title> </head> <body> <input type="button" onclick="setItems()" value="存值" /> <input type="button" onclick="getItems()" value="取值" /> <input type="button" onclick="deleteItem()" value="删除" /> </body> <script src="js/jquery.min.js"></script> <script> //localStorage存值永久有效 function setItems(){ var user = {}; user.name = "Adam Li"; user.age = 25; user.home = "China"; localStorage.setItem("userinfo",JSON.stringify(user)); } //localStorage取值 function getItems(){ var data = JSON.parse(localStorage.getItem("userinfo")); console.log("name:"+data.name+" age:"+data.age+" home:"+data.home); } //localStorage删除指定键对应的值 function deleteItem(){ localStorage.removeItem("userinfo"); console.log(localStorage.getItem("userinfo")); } </script> </html>
