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>
