如何将字符串转换为对象数组？

Question

我有以下字符串："[['ABB','ACC','ADD'],['FGG','FHH','FJJJ'],['MNN','MOO','MPP']]"我想将它转换为对象数组[['ABB','ACC','ADD'],['FGG','FHH','FJJJ'],['MNN','MOO','MPP']]我尝试了很多事情，但我做不到        function nextQuess() {        var ffa = JSON.stringify("<%- hola %>");  // from ejs variable "[['ABB','ACC','ADD'],['FGG','FHH','FJJJ'],['MNN','MOO','MPP']]"        // var ff = JSON.parse([ffa])        // console.log('hello', ff);        console.log("Hello", ffa);    } 

Answer 1

您需要替换'为"然后解析

 '(.*?)'(?=(,|\])

'(.*?)'- 匹配 ' 后跟任何零更多时间（懒惰模式）（捕获组 1）

(?=(,|\]))- 匹配必须后跟,或]

let str = "[['ABB','ACC','ADD'],['FGG','FHH','FJJJ'],['MNN','MOO','MPP']]"

let replacedString = str.replace(/'(.*?)'(?=(,|\]))/g, "\"$1\"")

let final = JSON.parse(replacedString)

console.log(final)

Answer 2

使用JSON.stringify(json)然后JSON.parse()

let jsonString = JSON.stringify([['ABB','ACC','ADD'],['FGG','FHH','FJJJ'],['MNN','MOO','MPP']]);

let array = JSON.parse(jsonString);

console.log(array);

或者你也可以试试eval()方法

let jsonArray = eval([['ABB','ACC','ADD'],['FGG','FHH','FJJJ'],['MNN','MOO','MPP']]);

console.log(jsonArray);
