使用JS解析JSON foreach，显示HTML列表 [英] Parse JSON foreach with JS, shows HTML list

问题描述

我目前正在尝试使用JavaScript解析JSON.我的问题是我希望输出看起来像这样:

I am currently trying to parse a JSON with JavaScript. My issue is that I'd like the output to look like this:

<li>AppName1</li>
<li>AppName2</li>
<!-- and so on... -->

但是，它只是行不通，我也不知道该如何实现.这是从JSON响应反序列化的对象:

However it just does not work and I don't know how to achieve that. This is the object deserialized from the JSON response:

{
  "data": [{
    "AppId": 1,
    "AppName": "AppName1",
    "AppSize": "2.1"
  }, {
    "AppId": 2,
    "AppName": "AppName2",
    "AppSize": ""
  }]
}

这是我的.js文件:

var xmlhttp = new XMLHttpRequest();
xmlhttp.onreadystatechange = function() {
  if (this.readyState == 4 && this.status == 200) {
    var myObj = JSON.parse(this.responseText);
    document.getElementById("test").innerHTML = myObj.AppName;
  }
};
xmlhttp.open("GET", "json.json", true);
xmlhttp.send();

这是在我的HTML文件中

This is in my HTML file

<p id="test"></p>

任何帮助将不胜感激，因为我似乎一点也不了解.非常感谢！

Any help would be appreciated as I really cannot seem to understand this a single bit. Thank you so much!

推荐答案

首先请注意，您只能将li元素用作<ul>或<ol>的子级，因此需要更改p元素.

Firstly note that you can only have li elements as children of <ul> or <ol>, so the p element needs to be changed.

AppName属性是data中对象的一部分，因此您将需要遍历它们:

The AppName property is part of the objects within data, so you will need to either loop through them:

myObj.data.forEach(function(o) {
   document.getElementById("test").innerHTML += '<li>' + o.AppName + '</li>';
}

或按索引分别访问它们:

Or access them, individually by index:

document.getElementById("test").innerHTML = '<li>' + myObj.data[0].AppName + '</li>'; // first item only

var myObj = {
  "data": [{
    "AppId": 3,
    "AppName": "AnimojiStudio",
    "AppSlug": "animojistudio",
    "AppIcon": "https:\/\/img.lmdinteractive.pro\/icons\/animojistudio.png",
    "AppUrl": "https:\/\/ipa.lmdinteractive.pro\/ipa\/appstore\/animojistudio.ipa",
    "AppVersion": "1.2.2",
    "AppSize": "2.1"
  }, {
    "AppId": 2,
    "AppName": "Cute Cut Pro",
    "AppSlug": "cute-cut-pro",
    "AppIcon": "http:\/\/is2.mzstatic.com\/image\/thumb\/Purple118\/v4\/03\/70\/69\/03706968-2399-a1d8-e7c4-12897394ead9\/source\/512x512bb.jpg",
    "AppUrl": "https:\/\/ipa.lmdinteractive.pro\/ipa\/appstore\/cutecutpro.ipa",
    "AppVersion": "",
    "AppSize": ""
  }]
}

document.getElementById("test").innerHTML = '<li>' + myObj.data[0].AppName + '</li>';

<ul id="test"><li>
