为什么我正在加载的图像丢失了？ [重复]

Question

我有一个实际上是排行榜的代码。我有3个问题需要修改代码，这是第一个（我将为每个代码创建单独的问题）。

第一个问题：我无法弄清楚为什么imgDiamonds丢失了，我只能在最终输出上看到一个黑点而不是Diamonds.png以及如何修复它。

结果如下：

在这里更清楚的是加载图像配置文件的代码的示例行，并且t工作正常：

profile1.img = "https://randomuser.me/api/portraits/men/12.jpg";

这是导致问题的缺失图像：

profile1.imgDiamonds = "Diamonds.png";

这是代码：

JS

// this is the array that will hold all the profile objects
let profiles = [];

let profile1 = {};
profile1.name = "Jim Bob";
profile1.job = "Doctor";
profile1.points = 1500;
profile1.img = "https://randomuser.me/api/portraits/men/12.jpg";
profile1.imgDiamonds = "Diamonds.png";
profiles.push(profile1);

let profile2 = {};
profile2.name = "Jane tanha";
profile2.job = "Dentist";
profile2.points = 2000;
profile2.img = "https://randomuser.me/api/portraits/women/22.jpg";
profile2.imgDiamonds = "Diamonds.png";
profiles.push(profile2);

let profile3 = {};
profile3.name = "Mike Jones";
profile3.job = "Medic";
profile3.points = 4000;
profile3.img = "https://randomuser.me/api/portraits/men/22.jpg";
profile3.imgDiamonds = "Diamonds.png";
profiles.push(profile3);

let profile4 = {};
profile4.name = "Sally Peterson";
profile4.job = "Agriculture";
profile4.points = 1900;
profile4.img = "https://randomuser.me/api/portraits/women/24.jpg";
profile4.imgDiamonds = "Diamonds.png";
profiles.push(profile4);

let profile5 = {};
profile5.name = "Sally Peterson";
profile5.job = "Pumper";
profile5.points = 1100;
profile5.img = "https://randomuser.me/api/portraits/women/24.jpg";
profile5.imgDiamonds = "Diamonds.png";
profiles.push(profile5);

let profile6 = {};
profile6.name = "Sally Peterson";
profile6.job = "Mother";
profile6.points = 1400;
profile6.img = "https://randomuser.me/api/portraits/women/24.jpg";
profile6.imgDiamonds = "Diamonds.png";
profiles.push(profile6);

let profile7 = {};
profile7.name = "Sally Peterson";
profile7.job = "Nurse";
profile7.points = 1400;
profile7.img = "https://randomuser.me/api/portraits/women/24.jpg";
profile7.imgDiamonds = "Diamonds.png";
profiles.push(profile7);

let profile8 = {};
profile8.name = "Sally Peterson";
profile8.job = "Taxi Diver";
profile8.points = 1400;
profile8.img = "https://randomuser.me/api/portraits/women/24.jpg";
profile8.imgDiamonds = "Diamonds.png";
profiles.push(profile8);

let profile9 = {};
profile9.name = "Sally Peterson";
profile9.job = "High School Student";
profile9.points = 1400;
profile9.img = "https://randomuser.me/api/portraits/women/24.jpg";
profile9.imgDiamonds = "Diamonds.png";
profiles.push(profile9);

let profile10 = {};
profile10.name = "Sally Peterson";
profile10.job = "Student";
profile10.points = 1500;
profile10.img = "https://randomuser.me/api/portraits/women/24.jpg";
profile10.imgDiamonds = "Diamonds.png";
profiles.push(profile10);

// sort the array by points
// b - a will make highest first, swap them so a - b to make lowest first
profiles.sort(function(a, b) {
  return b.points - a.points;
})


let count = 1;
profiles.forEach(function(entry) {
let profilesDiv = document.getElementsByClassName('profiles')[Math.floor((count-1)/5)];

  let img = document.createElement('img');
  img.className = "profilePic";
  img.src = entry.img;

  let imgDiamonds = document.createElement('imgDiamonds');
  imgDiamonds.className = "profileDia";
  imgDiamonds.src = entry.imgDiamonds;


  let profile = document.createElement('div');
  profile.className = "profile";
  profile.innerHTML = "<div class='name'>" + entry.name + "</div>";


  let job = document.createElement('span');
  job.className = "job";
  job.textContent = entry.job;
  profile.appendChild(job);
  profile.prepend(img);
  profile.prepend(imgDiamonds);


  let points = document.createElement('span');
  points.className = "points";
  points.textContent = entry.points;
  profile.appendChild(points);
  profile.prepend(img);
  profile.prepend(imgDiamonds);

  var span = document.createElement("span");
  span.textContent = count + '. ';
  span.className = "count";
  profile.prepend(span);
  profilesDiv.appendChild(profile);
  count++;

});

Answer 1

问题是这条线：

let imgDiamonds = document.createElement('imgDiamonds');

imgDiamonds不是HTML属性。这应该做的伎俩：

let imgDiamonds = document.createElement('img');

还要相应地编辑你的css：

.profile img.profilePic {
  position: absolute;
  margin: -50px 70px 50px 90px;
  background: #2f293d;
  border: 1px solid #2f293d;
  padding: 4px;
  border-radius: 50%;
  box-shadow: .2rem .2rem 1rem rgba(0, 0, 0, .5);
}

.profile img.profileDia {
  position: absolute;
  margin: -50px 70px 50px 90px;
  background: #2f293d;
  border: 1px solid #2f293d;
  padding: 4px;
  box-shadow: .2rem .2rem 1rem rgba(0, 0, 0, .5);
}

Answer 2

let imgDiamonds = document.createElement('imgDiamonds');

应该是let imgDiamonds = document.createElement('img');

你的Object属性声明也可以更好地阅读（恕我直言）。这个 ：

let profile1 = {};
profile1.name = "Jim Bob";
profile1.job = "Doctor";
profile1.points = 1500;
profile1.img = "https://randomuser.me/api/portraits/men/12.jpg";
profile1.imgDiamonds = "Diamonds.png";
profiles.push(profile1);

（对我来说）会更好地阅读：

let profile1 = {
  name: "Jim Bob",
  job: "Doctor",
  points: 1500,
  img: "https://randomuser.me/api/portraits/men/12.jpg",
  imgDiamonds: "Diamonds.png"
}

profiles.push(profile1);
