element多个相同的select不允许重复选择
<template>
<div class="com_searchAndpageBoxPadding">

</script><style lang="scss" src="@/assets/css/card.scss"></style>动态循环出的多个select 不能重复选择相同的数据
先看效果图
代码如下：
<template>
<div class="program" v-for="(parItem,index) in parArr" :key="parItem.guid">
<Select v-model="parItem.id" @on-change="onChangeProgram">
<Option v-for="(subItem,idx) in programList" :key="subItem.id" :data-index='idx'
v-show="parItem.id == subItem.id || !selectIdsArr.includes(subItem.id)"
:value="subItem.id> {{subItem.name}}</Option>
</Select>
</div>
</template><script>
export default {
data() {
return {
parArr:[{guid:'ddddd',id:null,},{guid:'eeeee',id:null,},{guid:'ffff',id:null,}],
selectIdsArr:[],
programList:[{
"id":1,
"name":"选项1"
},{
"id":2,
"name":"选项2"
},{
"id":3,
"name":"选项3"
}],
}
},
methods: {
onChangeProgram() {
this.selectIdsArr = [];
for (const item of this.parArr) {
if (item.id) {
this.selectIdsArr.push(item.id);
}
}
},
},
}
</script>以上为个人经验，希望能给大家一个参考，也希望大家多多支持编程网。
