我已经编写了一个JavaScript警告消息代码,在1和2两个代码中,它首先显示警示信息再显示HTML内容。我该怎么做才能先运行HTML内容然后再运行JavaScript代码?
代码1:
<!DOCTYPE html>
<html>
<head>
<title>Hello, World !</title>
</head>
<body>
<h1>I am learning JavaScript.</h1>
<div id="Content">
<p>This is a paragraph tag. Here the content of html.</p>
</div>
<script src="text.js"></script>
</body>
</html>
代码 2
<!DOCTYPE html>
<html>
<head>
<title>Hello, World !</title>
</head>
<body>
<h1>I am learning JavaScript.</h1>
<div id="Content">
<p>This is a paragraph tag. Here the content of html.</p>
</div>
<script>
alert(" This is alert message.");
</script>
</body>
</html>
