For循环发行JavaScript

Question

[

  // Define the variables
  var stringIn = [];
  var finalMessage = "Thanks for participating!";
  
  // Get input from user
  stringIn[0] = prompt("Enter the first string:");
  stringIn[1] = prompt("Enter the second string:");
  stringIn[2] = prompt("Enter the third string:");
  stringIn[3] = prompt("Enter the fourth string:");
  stringIn[4] = prompt("Enter the fifth string:");
  
  // For loop and display
  for(var myCounter = 0; myCounter < 5; myCounter++) {
    document.write("You entered: " + stringIn + "\n");
  }
  
  document.write("\n" + finalMessage);

我的输出应为：您输入了：Alpha您输入了：Bravo您输入了：Charlie您输入了：Delta您输入了：回声

但我得到：

您输入：Alpha，Bravo，Charlie，Delta，Echo您输入了：Alpha，Bravo，Charlie，Delta，Echo您输入了：Alpha，Bravo，Charlie，Delta，Echo您输入了：Alpha，Bravo，Charlie，Delta，Echo您输入了：Alpha，Bravo，Charlie，Delta，Echo

我已经添加了代码以帮助解决我的问题。 FireFox Web控制台不显示任何错误，如果出现错误，则不会有任何输出。此代码有什么问题？

Answer 1

您只需要在迭代器中访问stringIn的索引。

stringIn[myCounter]

  // Define the variables
  var stringIn = [];
  var finalMessage = "Thanks for participating!";
  
  // Get input from user
  stringIn[0] = prompt("Enter the first string:");
  stringIn[1] = prompt("Enter the second string:");
  stringIn[2] = prompt("Enter the third string:");
  stringIn[3] = prompt("Enter the fourth string:");
  stringIn[4] = prompt("Enter the fifth string:");
  
  // For loop and display
  for(var myCounter = 0; myCounter < 5; myCounter++) {
    document.write("You entered: " + stringIn[myCounter] + "\n");
  }
  
  document.write("\n" + finalMessage);

Answer 2

应该是

  for(var myCounter = 0; myCounter < 5; myCounter++) {
    document.write("You entered: " + stringIn[myCounter] + "\n");
  }
