我需要循环一个 javascript 对象数组
这是我的对象响应:

我想做这样的事情:
var dataStr = JSON.stringify(response);
var dataPrs = JSON.parse(dataStr);
var dataList = JSON.stringify(dataPrs.items);
dataStr = JSON.stringify(dataList);
dataPrs = JSON.parse(dataStr);
dataListPrs.forEach( console.log(dataPrs.htmlLink) );
最佳答案
您不需要每次都执行 JSON.stringify 和 JSON.parse。
仅当您要将 Javascript 对象转换为 JSON 字符串时才需要 JSON.stringify
和 JSON.parse 仅当您要将 JSON 字符串转换为 Javascript 对象并希望使用 key 访问其值时。
所以，您需要的是:

const items = data.items
items.forEach(x => console.log(x.htmlLink))关于javascript:对象数组循环，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/55938445/
