1. 绑定样式对象
语法示例
- 绑定对象
<div id="app">
<div v-bind:style="{ color: activeColor, fontSize: fontSize + 'px' }">xxxxxx</div>
</div>
- 在vue实例中定义样式
data: {
activeColor: 'green',
fontSize: 30
}
完整示例
- 代码
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>CROW-宋</title>
<script src="https://cdn.staticfile.org/vue/2.2.2/vue.min.js"></script>
</head>
<body>
<div id="app">
<div v-bind:style="{ color: activeColor, fontSize: fontSize + 'px' }">碧玉妆成一树高</div>
</div>
<script>
new Vue({
el: '#app',
data: {
activeColor: 'green',
fontSize: 30
}
})
</script>
</body>
</html>

2. 直接绑定样式对象
语法示例
- 绑定样式对象
<div v-bind:style="styleObject">xxxxx</div>
- vue实例中定义样式对象
data: {
styleObject: {
color: 'green',
fontSize: '30px'
}
}
完整示例
- 代码
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>CROW-宋</title>
<script src="https://cdn.staticfile.org/vue/2.2.2/vue.min.js"></script>
</head>
<body>
<div id="app">
<div v-bind:style="styleObject">碧玉妆成一树高</div>
</div>
<script>
new Vue({
el: '#app',
data: {
styleObject: {
color: 'green',
fontSize: '30px'
}
}
})
</script>
</body>
</html>
-
结果显示

3. 绑定多个样式对象
完整示例
<html>
<head>
<meta charset="utf-8">
<title>CROW-宋</title>
<script src="https://cdn.staticfile.org/vue/2.2.2/vue.min.js"></script>
</head>
<body>
<div id="app">
<div v-bind:style="[baseStyles, overridingStyles]">碧玉妆成一树高</div>
</div>
<script>
new Vue({
el: '#app',
data: {
baseStyles: {
color: 'green',
fontSize: '30px'
},
overridingStyles: {
'font-weight': 'bold'
}
}
})
</script>
</body>
</html>
-
结果显示

覆盖顺序
- 和vue实例中定义样式的顺序无关
- 和绑定的数组中成员顺序有关
如果如下修改，字将是绿色的：
<div v-bind:style="[overridingStyles,baseStyles]">碧玉妆成一树高</div>
