Cordova Storage使用

1.设置html按钮标签

<button id="set">设置storage</button>
<button id='get'>获取storage</button>
<button id='remove'>删除单个storage</button>
<button id='getByKey'>索引获取storage</button>
<button id='length'>获取长度</button>
<button id="clear">清空storage</button>

2. localStorage.setItem(key,value) 存储storage

document.getElementById('set').onclick=function(){
    localStorage.setItem('name','xxx');
    localStorage.setItem('age',18);
}

3.localStorage.getItem(key) 读取storage

document.getElementById('get').onclick=function(){
    alert(localStorage.getItem('name')+localStorage.getItem('age'));
}

4.localstorage.removeItem(key) 根据key删除storage

document.getElementById('remove').onclick=function(){
    // 指定单个删除
    localStorage.removeItem('name');
}

5.localStorage.key(index) 获取索引的key值

document.getElementById('getByKey').onclick=function(){
    // key是根据字母顺序的 字母越小排越前
    alert(localStorage.key(0))
}

6. localstorage.length 获取

document.getElementById('length').onclick=function(){
    alert(localStorage.length);
}

7.localstorage.clear() 清空storage

document.getElementById('clear').onclick=function(){
    // 全部删除
    localStorage.clear();
}
