HTML5本地存储& jQuery：删除以某个单词开头的localstorage键 [英] HTML5 Localstorage & jQuery: Delete localstorage keys starting with a certain word

问题描述

我有两个应用程序与localstorage一起工作，我想知道如何删除所有以note-和todo-开头的密钥。我知道localstorage.clear（）清除了所有内容，但那不是我的目标。

以下是本地存储中的示例：

我想用一个按钮删除所有的todo- *点击和所有的笔记 - *与其他按钮点击使用jquery。

非常感谢

解决方案

（key）{
if（/ ^ todo- | ^ note - /。test（（key））{
$> $ $ $ $ $ $ $ $ b $ forEach key））{
localStorage.removeItem（key）;
}
}）;

I have 2 apps working together with localstorage and I was wondering how can I delete all the keys which start with note- and todo- . I know localstorage.clear() clears everything but thats not my aim.

Here is an example of what I have in my localstorage:

Where I want to delete all the todo-* with a button click and all note-* with other button click using jquery.

Thanks alot

解决方案

Object.keys(localStorage)
      .forEach(function(key){
           if (/^todo-|^note-/.test(key)) {
               localStorage.removeItem(key);
           }
       });
