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);

我的输出应该是: 您输入的是:阿尔法 您输入的是: 布拉沃 您输入的是:查理 您输入: 达美航空 您输入:回声

但我得到:

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 您输入了:Alpha、Bravo、Charlie、Delta、Echo

我添加了代码来帮助解决我的问题。 FireFox Web 控制台没有显示任何错误，如果出现错误，则不会有任何输出。这段代码有什么问题？

您只需要在迭代器中访问 stringIn 的索引即可。

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);
