從數組中獲取最高3個數字？

Question

下面的代碼返回數組中最大的數字。我試圖弄清楚如何從數組中獲得前3個數字，並且一直無法弄清楚。

我也想弄清楚如何列出相應的作業與他們的分數。目前H1的「你的最高分數」只顯示數字，並沒有通過工作（或var名稱的最高數字）。

有關如何完成此任何想法？

謝謝！

HTML：

<div> 
    <h3> Job 95- <span id="score95"> </span> </h3> 
    <h3> Job 96- <span id="score96"> </span> </h3> 
    <h3> Job 97- <span id="score97"> </span> </h3> 
    <h3> Job 98- <span id="score98"> </span> </h3> 
    <h3> Job 99- <span id="score99"> </span> </h3> 
    <h3> Job 100- <span id="score100"> </span> </h3> 
    <h1> Your highest score was: <span id="highest"></span></h1> 
</div> 

JS

var job95 = 100; 
var job96 = 100; 
var job97 = 100; 
var job98 = 100; 
var job99 = 100; 
var job100 = 100; 

$("#no15").click(function() { 
    console.log('clicked15') 
    job95 += 10; 
    job96 += 20; 
    job97 += 30; 
    job98 += 40; 
    job99 += 50; 
    job100 += 60; 
    $('#score95').html(job95); 
    $('#score96').html(job96); 
    $('#score97').html(job97); 
    $('#score98').html(job98); 
    $('#score99').html(job99); 
    $('#score100').html(job100); 

    var numArray = [job95,job96, job97, job98, job99,job100] 
    $('#highest').html(Math.max.apply(Math,numArray)); 
});

排序從最低到最高，然後切片。例如：

var arr = [1, 3, 2, 1, 5, 6, 3]; 
 
//Sort the array from lowest to highest 
 
//Thanks to Charlietfl, I forgot to sort it numerically 
 
arr.sort(function(a, b) { 
 
    return a - b; 
 
}); 
 
//Get the highest 3 
 
var top3Arr = arr.slice(-3); 
 
console.log(top3Arr) 
 

 

 
//This is an array, so if you want each number individually just access the array 
 

 
var highest = top3Arr[2]; 
 
var secondHighest = top3Arr[1]; 
 
var thirdHighest = top3Arr[0];
