vue 样式绑定

绑定HTML Class

内联：
<div class="static"
  v-bind:class="{ active: isActive, 'text-danger': hasError }"></div>
定义对象：
<div v-bind:class="classObject"></div>
定义数组
<div v-bind:class="[activeClass, errorClass]"></div>
<div v-bind:class="[isActive ? activeClass : '', errorClass]"></div>
<div v-bind:class="[{ active: isActive }, errorClass]"></div>


// 变量定义
data: {
  isActive: true,
  error: null,
  activeClass: 'active',
  errorClass: 'text-danger'
},

1、计算属性

computed: {
  classObject: function () {
    return {
      active: this.isActive && !this.error,
      'text-danger': this.error && this.error.type === 'fatal'
    }
  }
}

2、绑定对象

data: {
  classObject: {
    active: true,
    'text-danger': false
  }
}

绑定HTML Style

属性
<div v-bind:style="{ color: activeColor, fontSize: fontSize + 'px' }"></div>
对象
<div v-bind:style="styleObject"></div>
数组
<div v-bind:style="[baseStyles, overridingStyles]"></div>


// 变量定义
data: {
  activeColor: 'red',
  fontSize: 30,
  styleObject: {
    color: 'red',
    fontSize: '13px'
  }
}
