引用JS
内部JS
直接写在html文件里, 用script标签包住
例子:
html
<!DOCTYPE html>
<html lang="zh_CN">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>在内部引入js弹窗警告框</title>
</head>
<body>
<script>
alert("Hello World")
</script>
</body>
</html>外部JS
代码写在以.js后缀的文件里, 通过script标签引入到html页面中
例子:
html
<!DOCTYPE html>
<html lang="zh_CN">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>在外部引入js弹窗警告框</title>
</head>
<body>
<script src="script.js"></script>
</body>
</html>js
alert("Hello World")内联JS
代码写在标签内部(了解即可, 后面Vue框架才是重点)
例子:
html
<!DOCTYPE html>
<html lang="zh_CN">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>在内联引入js弹窗警告框</title>
</head>
<body>
<button onclick="alert('可能吗¿')">点击月薪过亿</button>
</body>
</html>
