輸入用戶inputed元素到數組在JavaScript

Question

我想知道到底是什麼我的代碼丟失或爲什麼它不會工作

<script> 
     var index = 0; 
     var name = []; 
     while (true) 
     {   
     var add = window.confirm("Would you like to enter an employee"); 
     if (add === true) 
     { 
     name[index] = prompt("Please enter and employee name"); 
     ++index; 
     } 
     else 
      break; 
     } 
     window.alert(name[0]); 

    </script> 

的window.alert只是看它是否被保存，我試着使用JS中的C++風格，我知道我應該做推式方法？但林不是很確定，所有它在警告框中說是未定義的，我不知道爲什麼，任何幫助將不勝感激，謝謝。我不知道什麼是什麼，什麼不允許在JavaScript中，我認爲增加的東西是相同的殭屍JS和C + +。

Answer 1

你需要有一個數組，推動要素，

var index = 0; 
var names = []; 
while (true) { 
    var add = window.confirm("Would you like to enter an employee"); 
    if (add === true) { 
    var newname = prompt("Please enter and employee name"); 
    names.push(newname); 
    ++index; 
    } else 
    break; 
} 
window.alert(names);

使用push到新的輸入添加到陣列像這樣：

var index = 0, employee; 
 
     var nameArr = []; 
 
     while (true) 
 
     {   
 
     var add = window.confirm("Would you like to enter an employee"); 
 
     if (add === true) 
 
     { 
 
     employee = prompt("Please enter and employee name"); 
 
     nameArr.push(employee); 
 
     ++index; 
 
     } 
 
     else 
 
      break; 
 
     } 
 
     window.alert(nameArr[0]); 
 
     console.log(nameArr);

遞歸

function addEmployee(arr) { 
 
     let name = arr ? arr : []; 
 
     let yes = confirm("Would you like to enter an employee"); 
 
     if (yes) { 
 
     let employee = prompt("Please enter and employee name"); 
 
      name.push(employee); 
 
      addEmployee(name); 
 
     } else { 
 
      alert(name); 
 
     } 
 
    }; 
 
    addEmployee();
