一个字符串对象如何转为指定的字符串

Question

//后端给了一个中文的key value很头疼，请问如何转换呢
"{"种类":"黑丝","价格":"100"}" => "黑丝,100"

Answer 1

let values = [];

JSON.parse('{"种类":"黑丝","价格":"100"}', (k, v) => {
    k && values.push(v);
});
values.join(',');

也可以通过正则：

const matches = '{"种类":"黑丝","价格":"100"}'.matchAll(/(?<=:")[^"]+/g);

for (let match of matches) {
    console.log(match);
    // ["黑丝", index: 7, input: "{"种类":"黑丝","价格":"100"}", groups: undefined]
    // ["100", index: 17, input: "{"种类":"黑丝","价格":"100"}", groups: undefined]
}
