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]
}
