vue 的全选组件封装你知道多少
效果
封装的组件
<template>
<el-form-item :label="label">
<el-checkbox :indeterminate="isIndeterminateBool" v-model="checkAll"
@change="handleCheckAllChange">全选
</el-checkbox>
<el-checkbox-group v-model="checkList" @change="handleCheckedCitiesChange">
<el-checkbox :label="key" v-for="(item,key) in this.channelList"
:key="key">{{ item }}
</el-checkbox>
</el-checkbox-group>
</el-form-item>
</template>
<script>
import {channelList} from "@/utils/app-channel";
export default {
name: "Index",
data() {
return {
//渠道列表 全部渠道
channelList: channelList,
// checkbox 的不确定状态，一般用于实现全选的效果
isIndeterminateBool: true,
//全选默认不勾选
checkAll: false,
data: this.checkList,
}
},
computed: {
checkList: {
get: function () {
return (this.item[this.formDBName] || '').split("|").filter(str => (!!str));
},
set: function (newValue) {
this.item[this.formDBName] = newValue.join("|");
}
}
},
props: {
//表单名称
label: {
type: String,
required: true
},
//当前选中项
item: {
type: Object,
required: true
},
formDBName: {
type: String,
required: true
}
},
methods: {
getArrayCheckList() {
return (this.item[this.formDBName] || '').split("|").filter(str => (!!str));
},
//将数据返回给父组件
setChooseData(data) {
this.$emit("choose-data", this.formDBName, data)
},
//value 代表选中还是未选中 ture false两个取值
handleCheckAllChange(value) {
const chooseChannel = Object.keys(this.channelList)
this.checkList = value ? chooseChannel : [];
this.isIndeterminateBool = false;
this.checkAll = value;
const formData = this.checkList.join("|");
this.setChooseData(formData)
},
//选中后计算全选
handleCheckedCitiesChange(value) {
const chooseChannel = Object.keys(this.channelList);
let checkedCount = value.length;
this.checkAll = checkedCount === chooseChannel.length;
this.isIndeterminateBool = checkedCount > 0 && checkedCount < chooseChannel.length;
const formData = value.join("|");
this.setChooseData(formData)
},
},
mounted() {
// .split("|").filter(str => (!!str && typeof (str) == 'string'))
}
}
</script>
<style scoped>
</style>
渠道列表
//
export const channelList = {
"anguo": "安果",
"baidu": "百度",
"huawei": "华为",
"samsung": "三星",
"oppo": "OPPO",
"sanliuling": "360",
"meizu": "魅族",
"vivo": "VIVO",
"wandoujia": "豌豆荚",
"xiaomi": "小米",
"yyb": "应用宝",
"yyh": "应用汇",
};
父组件使用
<el-card shadow="hover">
<multiple-choice :item="item" label="渠道/广告开关"
form-d-b-name="channel" @choose-data="onCheckResult"></multiple-choice>
</el-card>
item[channle] 是存入字符串的以|分割的数据
比如
baidu|anguo|yyb
这样
onCheckResult
onCheckResult(dbName, res) {
this.item[dbName] = res;
}
