vue.js开发之开关(switch)组件

最近开发组件的时候，自定义开发了开关(switch)组件，现将代码整理如下，方便日后复用。

toggle-switch.vue　　

<template>
	<label role="checkbox" :class="['switch', { toggled }]">
	    <input type="checkbox"
	           class="switch-input"
	           @change="toggle"/>
	    <div class="switch-core"
	         :style="{backgroundColor: toggled ? colorChecked  : colorUnchecked}">
	      <div class="switch-button"
	           :style="{transition: `transform ${speed}ms`,
	           transform: toggled ? null: `translate3d(34px, 0px, 0px)`}">
	      </div>
	    </div>
	    <span class="switch-label label-right"
	          v-if="toggled"
	          v-html="labelChecked">
	     </span>
	    <span class="switch-label label-left"
	          v-html="labelUnchecked" v-else>
	    </span>
	  </label>
</template>

<script>
	export default {
	    name: 'ToggleSwitch',
	    data () {
	      return {
	        toggled: this.value,
	        colorChecked: '#f55318',
	        colorUnchecked: '#25b9e9',
	        labelChecked: '开',
	        labelUnchecked: '关'
	      }
	    },
	    props: {
	      value: {
	        type: Boolean,
	        default: true
	      },
	      speed: {
	        type: Number,
	        default: 100
	      }
	    },
	    methods: {
	      toggle (event) {
	        this.toggled = !this.toggled
	        this.$emit('change', this.toggled)
	      }
	    }
	  }
</script>
