十分钟就能写好一个switch组件，它不香吗

之前看过许多许多组件都喜欢使用input来编写swich组件，实际不需要那么复杂，用自定义v-model也可以完美解决，还可以减少DOM结构。switch组件就是一个圆角矩形和一个小圆球一左一右配合就能简单实现。好的废话不多说。直接效果图。自定义的功能大家随意增加即可！写法上不一定好，仅供大家参考！

<template>

  <div>
    <span :class="[value?'switch-content active':'switch-content',disabled?'disabled':'']" @click="handleSwitch()">
      <span v-if="showText" :class="[value?'switch-text active':'switch-text']">{{ value ? '开' : '关' }}</span><span
        :class="[value?'switch-bar active':'switch-bar']">
      <span v-if="loading">
      <i :class="[loading?`loading`:'']">
      </i>
    </span>
    </span>
    </span>
  </div>

</template>

<script>
export default {
  name: "index",
  model: {
    prop: 'switchValue',
    event: 'change'
  },
  props: {
    switchValue: {
      type: Boolean
    },
    disabled: {
      type: Boolean
    },
    loading: {
      type: Boolean

    },
    showText: {
      type: Boolean
    }
  },
  data() {
    return {
      value: this.switchValue
    }
  },
  watch: {
    switchValue(val) {
      this.value = val;
    }

  },
  methods: {
    handleSwitch() {

      if (this.disabled) {
        return
      }
      this.value = !this.value
      this.$emit('change', this.value)


    }
  }
}
</script>
