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 "
>
<div
class="switch-button"
:style="{
transition: `transform ${speed}ms`,
transform: toggled "
></div>
</div>
<span class="switch-label label-right" v-if="toggled" v-html="labelChecked">
</span>
<span class="switch-label label-left" v-html="labelUnchecked" v-else>
</span>
</label>
</template>
<script>
export default {
name: "ToggleSwitch",
data() {
return {
toggled: this.value
};
},
props: {
value: {
type: Boolean,
default: true
},
speed: {
type: Number,
default: 100
},
labelChecked: {
type: String,
default: "启用"
},
labelUnchecked: {
type: String,
default: "停用"
},
colorChecked: {
type: String,
default: "#11CED2"
},
colorUnchecked: {
type: String,
default: "#E6EAF1"
}
},
watch: {
value: function(val) {
this.value = val;
}
},
methods: {
toggle(event) {
this.toggled = !this.toggled;
this.$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;
}
},
}
以上这篇vue.js封装switch开关组件的操作就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持。
