localStorage的使用

localStorage缓存基本使用
1.存值

// 三种方法
localStorage.setItem('name','value')
localStorage.name = 'value';
localStorage['name'] = 'value';

2.取值

localStorage.getItem('name')
localStorage['name']
localStorage.name

3.重新赋值

localStorage.setItem('name','value2')
localStorage.name = 'value2';
localStorage['name'] = 'value2';

4.删除一个存储

localStorage.removeItem('name');

5.清除所有存储

localStorage.clear()

6.获取所有值

for(let key in localStorage)
{console.log(localStorage[key])}
