如何將字符串轉換為對象數組？

Question

我有以下字符串：

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

我想將它轉換為對象數組

[['ABB','ACC','ADD'],['FGG','FHH','FJJJ'],['MNN','MOO','MPP']]

我嘗試做很多事情，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

您需要將'替換為"然后解析

 '(.*?)'(?=(,|\])

• '(.*?)' - 匹配 ' 后跟任何零次（懶惰模式）（捕獲組 1）
• (?=(,|\\])) - 匹配后必須跟,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);

或者你也可以嘗試eval()方法

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