Effect.
Encapsulated component
Select all {{item}} import {channelList} from "@ / utils/app-channel" Export default {name: "Index", data () {return {/ / Channel list all channels channelList: channelList, / / uncertain status of checkbox Generally used to achieve the effect of all selection isIndeterminateBool: true, / / check all defaults: 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: {/ / form name label: {type: String, required: true}, / / currently selected item: {type: Object, required: true}, formDBName: {type: String, required: true}} Methods: {getArrayCheckList () {return (this.item [this.formDBName] | |') .split ("|") .filter (str = > (!! str) }, / / return the data to the parent component setChooseData (data) {this.$emit ("choose-data", this.formDBName, data)}, / / value represents whether the two values of ture false, handleCheckAllChange (value) {const chooseChannel = Object.keys (this.channelList) this.checkList = value, are selected or not selected?

Channel list
/ export const channelList = {"anguo": "an Guo", "baidu": "Baidu", "huawei": "Huawei", "samsung": "Samsung", "oppo": "OPPO", "sanliuling": "sanliuling", "meizu": "Meizu", "vivo": "VIVO", "wandoujia": "Pea pod", "xiaomi": "Xiaomi" "yyb": "YingYongBao", "yyh": "Application Exchange",}
Parent component use
Item [channle] is stored in a string to | split the data.
such as
Baidu | anguo | yyb
