我无法在 JSON 中推送对象，但 console.log() 有效

Question

我无法在 JSON 中推送对象，但 console.log() 可以工作。 console.log() 显示添加了一个对象，但是没有出现json字符串？

 var results = [{ "id": 0, "name": "Green", "category": "project", "year": 2008, "description": "my description", "comments": [{ "rating": 5, "comment": "Perfect", "author": "Sandra", "date": "2012-10-16T17:57:28.556094Z" }, { "rating": 4, "comment": "Cool", "author": "Milena", "date": "2014-09-05T17:57:28.556094Z" }, { "rating": 3, "comment": "No bad", "author": "Milan", "date": "2015-02-13T17:57:28.556094Z" }, { "rating": 4, "comment": "Good job", "author": "Toma", "date": "2013-12-02T17:57:28.556094Z" }, { "rating": 2, "comment": "OK", "author": "Aleksandar", "date": "2011-12-02T17:57:28.556094Z" }] }]; document.getElementById('show').innerHTML = results[0].comments[1].author; document.getElementById("sendComment").onclick = function() { var hg = { "rating": 1, "comment": "Hello", "author": "X", "date": "2014-09" } results[0].comments.push(hg); console.log(results[0].comments); }

 <div id='show'></div> <button id='sendComment'>Send</button>

Answer 1

results[0].comments 是对象数组，而不是 JSON 字符串。 一切正常。 新对象被添加到数组中。
