解析花括号内的内容

首先，您给的返回格式应该是一个 JSON。 所以我认为您给的这个例子不完整，并不符合JSON 格式，具体可以去 bejson.com 网站做一下格式校验。 补全之后的样子应该是:

{ "result": { "imageurl": "http://example.com", "data": [{ "id": 101, "name": "", "type": "Dynamic", "seeall": false, "vertical": false, "list": [] }, { "id": "8_121", "name": "Weekly Top 20", "type": "songs", "seeall": true, "vertical": false, "section_id": "26", "list": [{ "id": "1801_1800323_7", "title": "Se\u00f1orita", "artist": "Shawn Mendes,Camila Cabello", "subtitle": "Shawn Mendes", "image": "1801/1800323/1800323_1564237811_200x200.jpg", "type": "songs", "albumid": "1800323" }, { "id": "1696_1695386_1", "title": "On My Way", "artist": "Alan Walker,Sabrina Carpenter,Farruko", "subtitle": "On My Way", "image": "1696/1695386/1695386_1552085406_200x200.jpg", "type": "songs", "albumid": "1695386" }, { "id": "1840_1839953_1", "title": "Memories", "artist": "Maroon 5", "subtitle": "Memories", "image": "1840/1839953/1839953_1569036611_200x200.jpg", "type": "songs", "albumid": "1839953" }, { "id": "1889_1888580_1", "title": "Ahimsa", "artist": "U2,A.R Rahman", "subtitle": "Ahimsa", "image": "1889/1888580/1888580_1574289013_200x200.jpg", "type": "songs", "albumid": "1888580" }, { "id": "1712_1711742_1", "title": "Sugar & Brownies", "artist": "Dharia", "subtitle": "Sugar & Brownies", "image": "1712/1711742/1711742_1553572206_200x200.jpg", "type": "songs", "albumid": "1711742" }, { "id": "1787_1786076_1", "title": "Beautiful People (feat.

把上面这个 JSON 字符串传递到前端就很容易了: let jret = JSON.parse('xxxx'); //xxx 就是你的返回内容 然后就很容易了: let dataArr = jret["result"]["data"]; 就拿到 data 数组了 dataArr[0]["id"] 就拿到第一个的 id 了
