如何創建，在每一個點擊按鈕上發現平均一個javascript

Question

如何創建一個JavaScript程序，發現在文本框中輸入數字的平均每次查找按鈕是點擊

var all=[]; 
$(document).on('click', 'check', function() 
{ 
    var second, minute, hours, aht; 
    second = document.getElementById('sec').value; 
    minute = document.getElementById('min').value; 
    hours = document.getElementById('hour').value; 

    nocAll.push = (eval(second + (minute * 60) + (hours * 60 *60))); 

    for(var i =0; i< nocAll.length; i++); 
    sum += parseInt(nocAll.elmt[i], 10); 
    aht = sum/nocAll.length; 

    document.getElementById("AHT").innerHTML = aht; 
}) 

這有試過

你編輯你的問題，所以這裏是一個方法來做到這一點。

你在代碼中有幾個問題。

nocAll是未定義（我想你的意思是使用all

Array.prototype.push是一個函數，all.push(value)

var all = []; 
 
// cache the elements you will be working with 
 
var $second = $('#sec') 
 
var $minute = $('#min') 
 
var $hour = $('#hour') 
 
var $aht = $("#AHT") 
 
// add two numbers together 
 
var add = function(a, b) { 
 
    return a + b 
 
} 
 

 
$(document).on('click', '.check', function() { 
 
    // get the current values of the inputs and convert to seconds 
 
    var hours = Number($hour.val()) * 60 * 60 
 
    var minutes = Number($minute.val()) * 60 
 
    var seconds = Number($second.val()) 
 
    // add total time in seconds to the all array 
 
    all.push(hours + minutes + seconds) 
 
    // just for dubugging 
 
    console.log(all) 
 
    // calculate the average by folding the array and adding the values 
 
    // then divide by the length 
 
    $aht.html('average seconds:' + all.reduce(add, 0)/all.length) 
 
})

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> 
 
<input type="text" id="hour" placeholder="hours" /> 
 
<input type="text" id="min" placeholder="minutes" /> 
 
<input type="text" id="sec" placeholder="seconds" /> 
 
<button class="check">check</button> 
 
<div id="AHT"></div>
