vue.js封装switch开关组件的操作

我的项目本来用的element,但是switch开关不符合设计要求,于是自己封装了一个switch组件,并且实现了switch开关的双向数据绑定

<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(32px, 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

};

},

props: {

value: {

type: Boolean,

default: true

},

speed: {

type: Number,

default: 100

},

labelChecked: {

type: String,

default: "启用"

},

labelUnchecked: {

type: String,

default: "停用"

},

colorChecked: {

type: String,

default: "#11CED2"

},

colorUnchecked: {

type: String,

default: "#E6EAF1"

}

},

watch: {

value: function(val) {

this.value = val;

}

},

methods: {

toggle(event) {

this.toggled = !this.toggled;

this.$emit("update:value", this.toggled);

this.$emit("change", event);

}

}

};

</script>

<style lang="scss" scoped>

.switch {

display: inline-block;

position: relative;

overflow: hidden;

vertical-align: middle;

user-select: none;

font-size: 10px;

cursor: pointer;

.switch-input {

display: none;

}

.switch-label {

position: absolute;

top: 0;

font-weight: 600;

color: white;

z-index: 2;

&.label-left {

left: 10px;

line-height: 20px;

border-top-left-radius: 2px;

border-bottom-left-radius: 2px;

color: #b5bdc8;

}

&.label-right {

right: 10px;

line-height: 20px;

border-top-right-radius: 2px;

border-bottom-right-radius: 2px;

}

}

.switch-core {

display: block;

position: relative;

box-sizing: border-box;

outline: 0;

margin: 0;

transition: border-color 0.3s, background-color 0.3s;

user-select: none;

width: 46px;

height: 20px;

border-radius: 4px;

line-height: 20px;

.switch-button {

width: 8px;

height: 16px;

display: block;

position: absolute;

overflow: hidden;

top: 2;

left: 2;

z-index: 3;

transform: translate3d(0, 0, 0);

background-color: rgba(255, 255, 255, 1);

border-radius: 4px;

margin-top: 2px;

margin-left: 2px;

}

}

}

</style>

调用开关组件

<toggle-switch

v-model="value"

:value.sync="value"

@change="switchChange"

>

</toggle-switch>

组件实现了switch开关的双向数据绑定,在父组件的methods中写一个@change事件

switchChange() {

console.log("switch值改变");

},

补充知识:vue 监控el-switch控件值的变化

我要的效果是根据系统消息的推送范围决定推送人标签的显示,如下图两种情况:

——选择全站推送

——选择个人推送

——页面定义的data对象

el-switch标签控件的代码, v-model="entity.pushRange"绑定的是推送范围字段

<el-form-item label="推送范围:" :label-width="formLabelWidth" prop="pushRange">

<el-switch

v-model="entity.pushRange"

active-color="#13ce66"

inactive-color="#ff4949"

active-text="全站"

inactive-text="个人"

@change="parens2($event)">

</el-switch>

</el-form-item>

下面的推送人id文本框,v-if=“FalgpushId”用来控制该文本框的显示,等于false时隐藏,true时显示(默认值为初始化时定义的FalgpushId = false,所以隐藏掉了)

<!-- 推送人id -->

<el-form-item label="推送人ID:" :label-width="formLabelWidth" prop="pushId" v-if="FalgpushId">

<el-input v-model="entity.pushId" :disabled="disabled" clearable></el-input>

</el-form-item>

methods中的方法,通过$event写法来监控该控件值的变化

methods:{

//该方法传入推送范围值,根据判断,决定是否展示其下面的推送人ID文本框

parens2(value){

let self = this ;

if(value == false){

//el-switch控件为 个人推送时,value为false

self.FalgpushId = true; //推送人id文本框显示

self.entity.pushRange = false;

}else if(value == true){

//el-switch控件为 true 全站推送,value为true

self.FalgpushId = false; //推送人id文本框隐藏

self.entity.pushRange = true;

}

},

}
