所以，我试图编写一个 do-while 循环语句来打印循环语句，但我的浏览器没有打印我的文本。我如何编辑我的代码来执行此操作？
<!DOCTYPE html>
<html>
<head>
<title>9. Looping Statements in Javascript</title>
</head>
<body>
<h1>9. Looping Statements in Javascript</h1>
<div id="playlist"></div>
<div id="someResult"></div>
<script>
var playlist = [];
playlist[0] = "Willy Wesly";
playlist[1] = "Childish Gambino";
playlist[2] = "Chance The Rapper";
playlist[3] = "Travi$ Scott";
playlist[4] = "Yeezy";
// while
/*
var i = 0;
while (i < playlist.length) {
var element = document.createElement('div');
element.innerHTML = "Now Playing: " + playlist[i];
i++;
document.body.appendChild(element);
}
*/
// do - while
var someResult = false;
do {
var element = document.createElement('div');
element.innerHTML = 'Will print AT LEAST once!';
}
while(someResult);
</script>
</body>
</html>
最佳答案
您需要将元素添加到文档正文。
var someResult = false;
do {
var element = document.createElement('div');
element.innerHTML = 'Will print AT LEAST once!';
//You need to add it to the body for it to show on the page
document.body.appendChild( element );
}
while(someResult);
