这篇文章主要介绍了Vue切换div显示隐藏,多选，单选代码解析,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下
切换div显示隐藏
1）单个item下的部分dom结构，显示或隐藏切换，不会修改其它同级dom的显示/隐藏
template dom结构
<div class="list-item" v-for="(list,index) in jobList">
<p class="job-name">{{list.jobName}}</p>
<p class="job-info">
<el-checkbox v-model="list.checked" @change="checkOne(index)"></el-checkbox>
<span class="info">{{list.locationDesc}} {{list.minDegreeDesc}}及以上 {{list.minExp}}年以上 {{list.jobMinSalary}}-{{list.jobMaxSalary}}</span>
<span class="time">发布时间：{{list.refreshTime}}</span>
<span class="desc" @click="toggle(index)">查看职位描述
<i class="up" v-if = "list.show"></i>
<i class="down" v-if = "!list.show"></i>
</span>
</p>
<div class="desc-info" v-if = "list.show">
{{list.jobDesc}}
</div>
</div>
script js
<script>
import api from '@/axios/api'
export default {
name: 'jobImport',
data(){
return{
companyName:'',
checkedAll:false,
isShow: true,
checkedNum:0,
num:'-1',
jobList:[
{name:"销售总监1"},
{name:"销售总监2"},
{name:"销售总监3"},
{name:"销售总监4"},
{name:"销售总监5"},
{name:"销售总监6"},
{name:"销售总监7"}
],}
},
mounted() {
for(let key in this.jobList){
this.jobList[key].checked = false;
this.jobList[key].show = false;
}
},
methods:{
toggle(index){
this.jobList[index].show = !this.jobList[index].show;
this.jobList.splice(index,1,this.jobList[index]); //当你利用索引直接设置一个项时,Vue 不能检测变动的数组,你可以使用 splice()解决
}
}
}
less 样式
.list-item{
padding-top:20px;
.job-name{
font-size:16px;
color:#333333;
font-weight: 800;
}
.job-info{
margin-top: 12px;
padding-bottom:20px;
border-bottom: 1px dashed #eeeeee;
font-size:14px;
color:#333333;
.info{
margin-left: 10px;
}
.time{
margin-left: 130px;
}
}
.desc{
float: right;
color:#ff6500;
cursor: pointer;
.up{
display: inline-block;
margin-left: 12px;
vertical-align: middle;
width: 11px;
height: 6px;
background: url("../img/icon_up.png") no-repeat;
}
.down{
display: inline-block;
margin-left: 12px;
vertical-align: middle;
width: 11px;
height: 6px;
background: url("../img/icon_down.png") no-repeat;
}
}
.desc-info{
padding: 12px;
background: #f8f9fb;
}
}
2）单个item，显示或隐藏切换，会修改其它同级dom的显示/隐藏。利用vue的计算属性computed 单选，单击选中，选中后，再点击无法取消
template dom结构
choosed 选中样式
span{
display: inline-block;
padding-left:10px;
padding-right: 10px;
margin-bottom: 10px;
margin-left: 5px;
margin-right: 5px;
min-width:44px;
height:26px;
text-align: center;
line-height: 26px;
color:#333;
font-size:14px;
cursor: pointer;
&.choosed{
background:#ff6500;
border-radius:2px;
color: #fff;
}
}
<div class="right hotcity-box">
<span v-for="(city,index) in city" @click="handleChoose(index)" :class="{'choosed':cityNum == index}">{{city.cityName}}</span> </div>
script js
export default {
name: 'search',
data(){
cityIndexNum:0,
city:[
{"cityName": '北京', "value": '1'},
{"cityName": '上海', "value": '2'},
{"cityName": '广州', "value": '3'},
{"cityName": '深圳', "value": '4'},
{"cityName": '天津', "value": '5'}
]
},
methods:{
handleChoose(index){
this.cityIndexNum = index;
}
},
computed:{
cityNum(){
return this.cityIndexNum;
}
}
}
2）单个item，显示或隐藏切换，会修改其它同级dom的显示/隐藏。 多选，单击选中，选中后，再点击，取消选中
template dom结构
<div class="right more">
<span v-for="(item, index) in exptIndustry" @click="handleChoose($event,index)" :class="{'choosed':item.ischeck}">{{item.fullName}}</span>
</div>
js
data(){
return {
industryIndexNum:0,
exptIndustry: [
{
"simpleName": "互联网1",
"fullName": "互联网1",
"value": "1",
"defaultName": "互联网1"
},
{
"simpleName": "互联网2",
"fullName": "互联网3",
"value": "2",
"defaultName": "互联网3"
}
]
}
},
methods:{
handleChoose(e,index){ //再次点击，取消选中状态
if (e.target.className.indexOf("choosed") == -1) {
e.target.className = "choosed"; //切换按钮样式
} else {
e.target.className = "";//切换按钮样式
}
if(index==-1){
this.industryDataInit();
}else{
let check = this.exptIndustry[index].ischeck;
this.exptIndustry[index].ischeck = !check;
console.log(this.exptIndustry[index].ischeck)
}
}
}
