Question

我正在尝试创建一个程序来重复输入的单词，因为它有多个字符，我尝试了几种不同的方法，这是迄今为止的工作。

<html>
<head>
<title>Repeat Word</title>
<script type="text/javascript">
//Program: Repeat Word
//Purpose: Repeat word for as many times as it has characters
//Date last modified: 4/11/12 
var word = "";

word = prompt("Enter the word you would like repeated?")


</script>
</head>
<body>
</form>
</body>
</html>

我希望它重复打招呼的一个例子是......

Enter a word: Hello

Hello

Hello

Hello

Hello

Hello

Answer 1

只需添加以下内容：

for(var i = 0, repeat = word.length; i < repeat; i++) {
    console.log(word);
}

Answer 2

var word = "Hello";
var letters = word.length;
for(var i = 0; i < letters; i++){
    document.write(word + '<br />');
}

Answer 3

尝试以下代码重复带有字符数的字词。

<html>
<head>
<title>Repeat Word</title>
<script type="text/javascript">
//Program: Repeat Word
//Purpose: Repeat word for as many times as it has characters
//Date last modified: 4/11/12 
var word = "";

word = prompt("Enter the word you would like repeated?")
for(var i=0;i<word.length;i++)
{
 document.write(word+"<br />");
}

</script>
</head>
<body>
</form>
</body>
</html>

Answer 4

<body>
     <script type="text/javascript">
           var repeat = prompt("Enter the word you would like repeated");
           for(var i=0;i<=repeat.length;i=i+1) {
                document.write(repeat + "<br />");
           }
     </script>
</body>
