Javascript-重復字符
[英]Javascript - Repeated Characters
問題描述
我正在嘗試創建一個程序來重復輸入的單詞（包含字符）的次數，我嘗試了幾種不起作用的方法，到目前為止，這是工作。
<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>
我想要重復打個招呼的例子是...
Enter a word: Hello
Hello
Hello
Hello
Hello
Hello

只需添加以下內容：
for(var i = 0, repeat = word.length; i < repeat; i++) {
console.log(word);
}

嘗試下面的代碼來重復帶有字符數的單詞。
<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>

<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>

用 javascript 中的重復字符替換 function 返回字符串
