英文:
Parsing response returned by mediawiki api
问题
程序相当简单（这使我对它的每个方面都挣扎了很长时间，这更令人尴尬）；HTML表单从用户那里获取输入；使用该输入作为搜索查询来查询媒体维基API，并获得响应。
我已经让这一部分工作，我可以呈现媒体维基返回的整个JSON对象。
从这里，我可以访问“pages”键的值。
但这并不容易阅读，所以我需要找出如何分别索引每个键，将这些值存储在某个JS对象中，然后我可以以正常方式显示这些值。
但是这比我想象的更困难。以下是我尝试过的一些方法。关于如何解析这个JSON对象以及为什么下面的方法失败了，有什么想法吗？
未能成功的方法
这两者都导致了“良性失败”，其中this.answer / this.ans_spec未定义
这两者都会导致JS块失败并进入catch块

PS - Scroll down to the bold italic thing for my question; everything else is context
The program is pretty simple (which makes how long I've struggled with every aspect of it even more embarrassing) ; html form takes an input from the user; queries the media wiki api using that input as the search query, gets the response.
I've gotten this much to work, & I can render the whole Json object media wiki returns.
From here I can access the value for the "pages" key.
But this is not easily readable, so I need to figure out how to index each of the keys separately, store those values in some JS object, & then I can display things in a normal way.
However this is proving more difficult than I'd have thought. Below are a bunch of things I tried. Any ideas on both how to parse this Json object & why the below things failed?
Things that did not work
this.answer = data.pages.excerpt
this.answer = data.pages
this.ans_spec = this.answer.excerpt
Both of the above resulted in "benign failures" where this.answer / this.ans_spec were undefined
this.answer = JSON.parse(data.pages)
this.answer = data.pages
this.ans_spec = JSON.parse(this.answer)
These properly caused the JS block to fail & go to the catch block

得分: 1
data.pages是一个对象数组，所以您只需要遍历它：
for (const page of data.pages) {
console.log(page.id);
console.log(page.excerpt);
// ...等等
}
英文:
data.pages is an array of objects, so you just need to loop over it:
for (const page of data.pages) {
console.log(page.id);
console.log(page.excerpt);
// ...etc
}
