使用个人资料照片创建动态LeaderBoard

问题描述 投票:-1回答:1

我很难找到一种方法来创建一个下面的排行榜,它使用变量来保存Javascript上的用户点数,以便通过更改用户来响应这些点的更改等级...

这是我想要实现的目标:

Here is the picture

我只想使用Javascript变量手动填写用户的点数据...让我们说所有的数据来自一个包含这些数据的javascript数组。

就像是 :

   user_1 = Nilesh S;
   user_2 = Shristi_S; 

   user_1 points = 1710;
   user_2 points = 1710;

   etc...

显然,如果我将Nilesh S(user_1)指向1000,那么Nilesh S排名将是第10 ......

我现在取得的成就就是创建那些圆形个人资料图片:)

以下是代码:

使用Javascript:

var img = document.createElement("IMG");
  img.setAttribute("src", "img_pulpit.jpg");
  img.setAttribute("width", "300");
  img.setAttribute("height", "300");
  img.setAttribute("alt", "The Pulpit Rock");
  document.body.appendChild(img);

HTML:

<div id="IMG">
<script src="Script.js"></script>
<link rel="stylesheet" type="text/css" href="Style.css">
  [1]: https://i.stack.imgur.com/zXm4N.png

CSS:

img {
      background: #2f293d;

   border: 1px solid #2f293d;
   padding: 6px;
   border-radius: 50%;
   box-shadow: .6rem .5rem 1rem rgba(0, 0, 0, .5);

}

任何解决方案将不胜感激。

下面是一种快速而又脏的方法,可以在对象数组中创建一些虚拟数据,对其进行排序并将其添加到页面中。

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

let profile1 = {};
profile1.name = "Jim Bob";
profile1.points = 1500;
profiles.push(profile1);

let profile2 = {};
profile2.name = "Jane Smith";
profile2.points = 1600;
profiles.push(profile2);

let profile3 = {};
profile3.name = "Mike Jones";
profile3.points = 400;
profiles.push(profile3);

let profile4 = {};
profile4.name = "Sally Peterson";
profile4.points = 1900;
profiles.push(profile4);

// 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 profilesDiv = document.getElementsByClassName('profiles')[0];

profiles.forEach(function(entry) {
	let profile = document.createElement('div');
    profile.className = "profile";
    profile.textContent = entry.name + " -- " + entry.points;
	profilesDiv.appendChild(profile);
});
.profile {
  border: 2px solid #222222;
  padding: 5px;
  margin: 5px;
  width: 50%;
}
<div class="profiles">

</div>
