作者:webqingyou
这篇文章主要为大家详细介绍了JS+Vue实现三级全选单选,文中示例代码介绍的非常详细,具有一定的参考价值,感兴趣的小伙伴们可以参考一下
本文实例为大家分享了JS+Vue实现三级全选单选的具体代码,供大家参考,具体内容如下
HTML
<div class="demand-class"> <div class="demand-class-title">需求分类</div> <div class="demand-check"> <input class="collect-top-checked" type="checkbox" v-model="demandChecked" @change="handledemandChecked" />全选 </div> <div class="package-type package-type2" v-for="(itns, itds) in classiFications" :key="itns.id" > <div class="package-type-title upgrading-title"> <input class="collect-top-checked" type="checkbox" v-model="ficationsCheck[itds]" @change="handleFicationsCheck(itds)" />{{ itns.name }} <div class="title-bor"></div> </div> <div class="package-type-content"> <div v-for="cd in itns.children" :key="cd.id" class="package-type-list" > <input class="collect-top-checked" type="checkbox" :value="cd.id" @change="handlechildrenCheck(itds, cd.id)" v-model="childrenCheck" /> <div>{{ cd.name }}</div> </div> </div> </div> </div>
js
data () { classiFications: [], //需求分类 接口给的集合 demandChecked: false, // 需求分类全选 ficationsCheck: [], //一级分类的单个全选 childrenCheck: [], //二级分类的全选 demandCheckedShow: false, //二级全选不触发接口 } methods: { // 需求分类全选 handledemandChecked() { if (this.demandChecked) { this.classiFications.forEach((it, is) => { this.ficationsCheck[is] = true; this.handleFicationsCheck(is); }); } else { this.classiFications.forEach((it, is) => { this.ficationsCheck[is] = false; this.handleFicationsCheck(is); }); } }, //一级分类所选 async handleFicationsCheck(id) { this.demandCheckedShow = true; let tmp = this.classiFications[id].childrenIds; //当前选择的id子集合 let tmpAdd = this.childrenCheck; //当前选择的id子集合 if (this.ficationsCheck[id]) { tmp.forEach((item) => { for (let i = 0; i < tmp.length; i++) { if (tmpAdd.indexOf(item) === -1) { this.childrenCheck.push(item); } } }); } else { tmp.forEach((item) => { for (let i = 0; i < tmp.length; i++) { if (tmpAdd.indexOf(item) !== -1) { this.childrenCheck.splice(this.childrenCheck.indexOf(item), 1); } } }); } // this.handleType(); this.currentPage = 0; await this.initSolutionAllPage(); this.demandCheckedShow = false; }, //二级分类所选 handlechildrenCheck(ids, cd) { console.log(cd); let cont = 0; // let conts = 0; let tmp = this.classiFications[ids].childrenIds; //当前选择的id子集合 let tmpAdd = this.childrenCheck; //当前选择的id子集合 if (this.ficationsCheck[ids]) { tmp.forEach((item) => { for (let i = 0; i < tmp.length; i++) { if (tmpAdd.indexOf(item) === -1) { this.ficationsCheck[ids] = false; } } }); } else { let tmpl = tmp.length === 1 ? 1 : tmp.length - 1; tmp.forEach((item) => { for (let i = 0; i < tmpl; i++) { if (tmpAdd.indexOf(item) !== -1) { // console.log(item); cont = cont + 1; } } }); if (cont === this.classiFications[ids].childrenIds.length) { this.ficationsCheck[ids] = true; } } // this.handleType(); if (!this.demandCheckedShow) { this.currentPage = 0; this.initSolutionAllPage(); } }, }
