一 用对象的方法绑定class
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>class与style绑定</title>
<meta name="viewport" content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" />
<script src="../js/vue.js" type="text/javascript" charset="utf-8"></script>
</head>
<body>
<div class="test">
<div class="otherClass" :class="{'class1':name1,'class2':name2}">我是文字</div> <!--法一:用对象的方式实现-->
</div>
<script type="text/javascript">
var myVue = new Vue({
el:".test",
data: {
name1: true,
name2: false,
}
})
</script>
</body>
</html>
最后实现效果
关于使用对象绑定class,还可以用另外一种写法:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>class与style绑定</title>
<meta name="viewport" content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" />
<script src="../js/vue.js" type="text/javascript" charset="utf-8"></script>
</head>
<body>
<div class="test">
<div class="test" :class="classObj">我是文字</div> <!--法一:用对象的方式实现-->
</div>
<script type="text/javascript">
var myVue = new Vue({
el:".test",
data: {
classObj: {
name1: false,
name2: true
}
}
})
</script>
</body>
</html>
最后的实现效果是:
二 用数组的方法绑定class
很简单,举个栗子:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>class与style绑定</title>
<meta name="viewport" content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" />
<script src="../js/vue.js" type="text/javascript" charset="utf-8"></script>
</head>
<body>
<div class="test">
<div class="otherClass" :class="[class1,class2]">我是文字</div> <!--法二:用数组的方式实现-->
</div>
<script type="text/javascript">
var myVue = new Vue({
el:".test",
data: {
class1: 'name1',
class2: 'name2',
}
})
</script>
</body>
</html>
实现效果:
其实在数组中还可以用判断是否显示这个类名,举个例子:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>class与style绑定</title>
<meta name="viewport" content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" />
<script src="../js/vue.js" type="text/javascript" charset="utf-8"></script>
</head>
<body>
<div class="test">
<div class="otherClass" :class="[class1,isShow? class2:'']">我是文字</div> <!--法二:用数组的方式实现-->
</div>
<script type="text/javascript">
var myVue = new Vue({
el:".test",
data: {
class1: 'name1',
class2: 'name2',
isShow: false
}
})
</script>
</body>
</html>
实现效果是:
三 用数组和对象混合的方法绑定class
举个例子:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>class与style绑定</title>
<meta name="viewport" content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" />
<script src="../js/vue.js" type="text/javascript" charset="utf-8"></script>
</head>
<body>
<div class="test">
<div class="otherClass" :class="[class1,{class2: isShow}]">我是文字</div> <!--法二:用数组的方式实现-->
</div>
<script type="text/javascript">
var myVue = new Vue({
el:".test",
data: {
class1: 'name1',
class2: 'name2',
isShow: true
}
})
</script>
</body>
</html>
实现的效果:
四 用对象的方式实现style绑定
举个例子:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>class与style绑定</title>
<meta name="viewport" content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" />
<script src="../js/vue.js" type="text/javascript" charset="utf-8"></script>
</head>
<body>
<div class="test">
<div class="otherClass" :style="{color: yanse, kuan + 'px' }">我是文字</div> <!--法一:用对象的方式实现-->
</div>
<script type="text/javascript">
var myVue = new Vue({
el:".test",
data: {
yanse: 'red',
kuan: 100,
}
})
</script>
</body>
</html>
实现效果如下:
其实也可以写为第二种方式:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>class与style绑定</title>
<meta name="viewport" content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" />
<script src="../js/vue.js" type="text/javascript" charset="utf-8"></script>
</head>
<body>
<div class="test">
<div class="otherClass" :style="styleObj">我是文字</div> <!--法一:用对象的方式实现-->
</div>
<script type="text/javascript">
var myVue = new Vue({
el:".test",
data: {
styleObj: {
color: 'pink',
'200px',
}
}
})
</script>
</body>
</html>
实现结果是:
五 用数组和对象混合的方式实现style绑定
举个例子:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>class与style绑定</title>
<meta name="viewport" content="width=device-width,initial-scale=1,minimum-scale=1,maximum-scale=1,user-scalable=no" />
<script src="../js/vue.js" type="text/javascript" charset="utf-8"></script>
</head>
<body>
<div class="test">
<div class="otherClass" :style="[styleObjectA,styleObjectB]">我是文字</div> <!--法一:用数组和对象的方式实现-->
</div>
<script type="text/javascript">
var myVue = new Vue({
el:".test",
data: {
styleObjectA: {
color: 'red',
'100px',
},
styleObjectB: {
top: '20px'
}
}
})
</script>
</body>
</html>
实现效果:
