将压缩的json数据存储在本地存储中

由于localStorage功能似乎仅限于处理字符串键/值对,您可以做的是使用lz-string库对json对象进行字符串化并压缩它,然后将其存储在localStorage中

用法

// sample json object
var jsonobj = {'sample': 'This is supposed to be ling string', 'score': 'another long string which is going to be compressed'}

// compress string before storing in localStorage    
localStorage.setItem('mystring', LZString.compress(JSON.stringify(jsonobj)));

// decompress localStorage item stored
var string = LZString.decompress(localStorage.getItem('mystring'))

// parse it to JSON object
JSON.parse(string);
