    storage.setItem("c",3);
}

var a=storage.a;
//第二种方法读取
var b=storage["b"];
//第三种方法读取
var c=storage.getItem("c");

//采用setItem()方法存储
sessionStorage.setItem('testKey','这是一个测试的value值'); // 存入一个值
//通过属性方式存储　　
sessionStorage['testKey'] = '这是一个测试的value值';

sessionStorage.getItem('testKey'); // => 返回testKey对应的值
sessionStorage['testKey']; // => 这是一个测试的value值

var userEntity = {
    name: 'tom',
    age: 22
};

sessionStorage也可存储Json对象：存储时，通过JSON.stringify()将对象转换为文本格式；读取时，通过JSON.parse()将文本转换回对象。
// 存储值：将对象转换为Json字符串
sessionStorage.setItem('user', JSON.stringify(userEntity));
 
// 取值时：把获取到的Json字符串转换回对象
var userJsonStr = sessionStorage.getItem('user');
userEntity = JSON.parse(userJsonStr);
console.log(userEntity.name); // => tom
