v-bind：style样式绑定

一、直接添加样式属性

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Vue 测试实例 - 菜鸟教程(runoob.com)</title>
<script src="https://cdn.bootcss.com/vue/2.2.2/vue.min.js"></script>
</head>
<body>
<div id="app">
    <div v-bind:style="{ color: activeColor, fontSize: fontSize + 'px',background:'red' }">内联样式</div>
</div>

<script>
new Vue({
  el: '#app',
  data: {
    activeColor: 'green',
    fontSize: 30
  }
})
</script>
</body>
</html>

二、绑定到样式对象

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Vue 测试实例 - 菜鸟教程(runoob.com)</title>
<script src="https://cdn.bootcss.com/vue/2.2.2/vue.min.js"></script>
</head>
<body>
<div id="app">
  <div v-bind:style="styleObject">绑定样式对象</div>
</div>

<script>
new Vue({
  el: '#app',
  data: {
    styleObject: {
      color: 'green',
      fontSize: '30px',
      background:'red'
    }
  }
})
</script>
</body>
</html>

三、多样式绑定

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Vue 测试实例 - 菜鸟教程(runoob.com)</title>
<script src="https://cdn.bootcss.com/vue/2.2.2/vue.min.js"></script>
</head>
<body>
<div id="app">
  <div v-bind:style="[baseStyles, overridingStyles]">多样式绑定</div>
</div>

<script>
new Vue({
  el: '#app',
  data: {
    baseStyles: {
      color: 'green',
      fontSize: '30px',
      background:'red'
    },
    overridingStyles: {
      'font-weight': 'bold'
    }
  }
})
</script>
</body>
</html>
