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);

    }

您需要替换'为"然后解析&nbsp;'(.*?)'(?=(,|\])'(.*?)'- 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)

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);
