1. 數組
<!doctype html>
<html lang="zh">
<head>
<meta charset="UTF-8">
<meta name="viewport"
content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Document</title>
<script src="../js/vue2.6.11.js"></script>
<style type="text/css">
.red {
color: red;
}
.size {
font-size: 20px;
}
</style>
</head>
<body>
<div id="app">
<label :class="['red', 'size']">滅絕植物：鄂西商陸</label>
</div>
<script>
var vm = new Vue({
el: '#app'
});
</script>
</body>
</html>
2. 變量,數據綁定的方式
<!doctype html>
<html lang="zh">
<head>
<meta charset="UTF-8">
<meta name="viewport"
content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Document</title>
<script src="../js/vue2.6.11.js"></script>
<style type="text/css">
.setRed {
color: red;
}
.fstyle {
font-style: italic;
}
</style>
</head>
<body>
<div id="app">
<div :class="mystyle">滅絕植物：鄂西商陸</div>
</div>
<script>
var vm = new Vue({
el: '#app',
data:{
mystyle:{setRed:true,fstyle:true}
}
});
</script>
</body>
</html>
3. 三元表達式
<!doctype html>
<html lang="zh">
<head>
<meta charset="UTF-8">
<meta name="viewport"
content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Document</title>
<script src="../js/vue2.6.11.js"></script>
<style type="text/css">
.setRed {
color: red;
}
.fstyle {
font-style: italic;
}
.active {
font-size: 20px;
}
</style>
</head>
<body>
<div id="app">
<div :class="['setRed','fstyle',flag?'active':'']">滅絕植物：鄂西商陸</div>
</div>
<script>
var vm = new Vue({
el: '#app',
data:{
flag:true,
mystyle:{setRed:true,fstyle:true}
}
});
</script>
</body>
</html>
4. 對象替代三元表達式，提高可讀性
<!doctype html>
<html lang="zh">
<head>
<meta charset="UTF-8">
<meta name="viewport"
content="width=device-width, user-scalable=no, initial-scale=1.0, maximum-scale=1.0, minimum-scale=1.0">
<meta http-equiv="X-UA-Compatible" content="ie=edge">
<title>Document</title>
<script src="../js/vue2.6.11.js"></script>
<style type="text/css">
.setRed {
color: red;
}
.fstyle {
font-style: italic;
}
.active {
font-size: 20px;
}
</style>
</head>
<body>
<div id="app">
<div :class="['setRed','fstyle',{'active':flag}]">滅絕植物：鄂西商陸</div>
</div>
<script>
var vm = new Vue({
el: '#app',
data:{
flag:true,
mystyle:{setRed:true,fstyle:true}
}
});
</script>
</body>
</html>
