解读mpvue官方文档的Class 与 Style 绑定及不支持语法

<template>
  <div>
      <div :class="career">测试</div>
  </div>
</template>

.career{
 background: red;
}

<template>
  <div>
      <div :class="computedClassObject">测试</div>
  </div>
</template>

computed: {
        computedClassObject () {
            return 'career'//重点：只需要在computed 方法生成 class的字符串
        }
    },

<style>
.career{
 background: red;
}
</style>

<template>
  <div>
      <div :style="styleObj">测试</div>
  </div>
</template>

data () {
    return {
        styleObj: {
            type: Object,
            default: function () {
                return {
                    background: 'black',
                    color: "yellow"
                }
            }
        }
    }
  },
