chrome.storage.local.set 使用可变键名 [英] chrome.storage.local.set using a variable key name

问题描述

在 Google Chrome 扩展程序中，我想使用 chrome.storage.local(相对于localStorage)因为:

In a Google Chrome Extension, I want to use chrome.storage.local (as opposed to localStorage) because:

1. 使用键值对，值可以是任何对象(而不是仅字符串)
2. 使用 setter storage.set 更改数据模型可以触发事件侦听器

1. With key-value pairs, the value can be any object (as opposed to string only)
2. Changes to the data model using setter storage.set can trigger an event listener

使用storage.set，我如何获得可变键名?

Using storage.set, how can I have a variable key name?

注意:如果我不使用setter，我可以做storage[v1]，但是对对象的更改不会触发事件监听器.

Note: If I don't use the setter, I can do storage[v1], but changes to the object won't trigger the event listener.

var storage = chrome.storage.local;
var v1 = 'k1';

storage.set({v1:'s1'});

storage.get(v1,function(result){
    console.log(v1,result);
    //console output = k1 {}
});
storage.get('v1',function(result){
    console.log(result);
    //console output = {v1:'s1'}
});

推荐答案

这是您要找的吗?

var storage = chrome.storage.local;

var v1 = 'k1';

var obj= {};

obj[v1] = 's1';

storage.set(obj);

storage.get(v1,function(result){
  console.log(v1,result);
  //console output = k1 {v1:'s1'}
});

storage.get('v1',function(result){
  console.log(result);
  //console output = {v1:'s1'}
})
