最近在开发一个流动性能，表单外面有单选框抉择，并且能够勾销抉择，在网上找到了办法并总结了一下，我参考的是这位前辈的代码。上面是我的代码：
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title> 应用 element-ui 中的 el-radio（单选框）组件实现选中和勾销选中性能 </title>
<!-- 引入 element-ui 的款式，-->
<link rel="stylesheet" href="https://unpkg.com/element-ui/lib/theme-chalk/index.css">
<script src="https://cdn.bootcss.com/vue/2.5.16/vue.min.js"></script>
<!-- 引入 element 的组件库 -->
<script src="https://unpkg.com/element-ui/lib/index.js"></script>
<style>
* {
margin: 0;
padding: 0;
}
</style>
</head>
<body>
<div id="app">
<el-button type="primary" @click="isShow = true"> 请抉择优惠活动 </el-button>
<el-dialog title="请抉择优惠活动" :close-on-click-modal="false" :visible.sync="isShow" width="731px">
<div class="model-body">
<el-form ref="form" :model="activityInfo" label-width="80px" label-position="top">
<el-form-item label="流动 1">
<el-radio-group v-model="activityInfo.radio1" :key="radioKey1">
<el-radio v-for="item in moneyOffList" :key="item.id" :label="item.id"
@click.native.prevent="changeRadio(item.id, 1)">{{item.activityName}}</el-radio>
</el-radio-group>
</el-form-item>
<el-form-item label="流动 2">
<el-radio-group v-model="activityInfo.radio2" :key="radioKey2">
<el-radio v-for="item in buyPurchaseList" :key="item.id" :label="item.id"
@click.native.prevent="changeRadio(item.id, 2)">{{item.activityName}}
</el-radio>
</el-radio-group>
</el-form-item>
<el-form-item label="流动 3">
<el-radio-group v-model="activityInfo.radio3" :key="radioKey3">
<el-radio v-for="item in couponList" :key="item.id" :label="item.id"
@click.native.prevent="changeRadio(item.id, 3)">{{item.activityName}}</el-radio>
</el-radio-group>
</el-form-item>
</el-form>
</div>
<div slot="footer" class="footer">
<!-- 办法返回一个数组, 对象中属性名的汇合 -->
<span class="left1"> 已选 {{Object.keys(activityInfo).length}} 个流动 </span>
<el-button class="cancel-style" size="small" @click="isShow = false"> 取 消 </el-button>
<el-button type="primary" @click="confirmActivit"> 确 认 </el-button>
</div>
</el-dialog>
</div>
<script>
new Vue({
el: '#app',
data() {
return {
// 显示或暗藏弹层
isShow: false,
// form 表单
activityInfo: {},
// 流动 1
moneyOffList: [],
// 流动 2
buyPurchaseList: [],
// 流动 3
couponList: [],
// 管制单选框点击选中和勾销
radioKey1: false,
// 管制单选框点击选中和勾销
radioKey2: false,
// 管制单选框点击选中和勾销
radioKey3: false,
// 模仿后端返回的数据
activityList: [
{
"activityName": "测试 1",
"marketingType": "1",
"id": "1564166823610396674",
"activityType": "5",
},
{
"activityName": "测试 2",
"marketingType": "1",
"id": "1564190540612743169",
"activityType": "5",

{
"activityName": "测试 3",
"marketingType": "2",

"activityType": "4",
},
{
"activityName": "测试 4",
"marketingType": "2",
"id": "1564201347171319810",
"activityType": "4",
},
{
"activityName": "测试 5",
"marketingType": "2",
"id": "1566712633057349634",
"activityType": "3",
},
{
"activityName": "测试 6",
"marketingType": "2",
"id": "1567399000281288706",
"activityType": "3",
},
],
}
},
mounted() {},
watch: {
isShow: {handler(newName, oldName) {if (newName) {
// 辨别各种流动类型
this.activityList.forEach(item => {if (item.marketingType == 1 && (item.activityType == '1' || item.activityType == '2' || item.activityType == '5')) {this.moneyOffList.push(item)
} else if (item.marketingType = 2 && item.activityType == '4') {this.buyPurchaseList.push(item)
} else if (item.marketingType = 2 && item.activityType == '3') {this.couponList.push(item)
}
});
} else {
// 敞开弹层之后初始化
this.moneyOffList = [];
this.buyPurchaseList = [];
this.couponList = [];
this.activityInfo = {};}
},
}
},
methods: {
// 点击单选框操作
changeRadio(val, number) {
// 如果未选中则单选框高亮，否则单选框勾销选中
this.activityInfo['radio' + number] = this.activityInfo['radio' + number] == val ? '' : val;
this['radioKey' + number] = !this['radioKey' + number];
// 去掉空值, 删除对象中的某一个属性和属性值
if (!this.activityInfo['radio' + number]) {delete this.activityInfo['radio' + number]
}
},
// 点击确定发送申请
confirmActivit() {
// Object.values, 获取对象中的属性值, 返回一个数组
let activityIds = Object.values(this.activityInfo);
// js 中的数组去掉空值 (点击单选框的时候曾经做了空值解决，这一步能够不要)
activityIds = activityIds.filter(function (s) {return s && s.trim();
});
console.log(activityIds, '传给后端的参数');
}
}
})
</script>
</body>
</html>通过这个需要我学到了单选框勾销选中的办法，学习了 vue 对对象中的属性动静赋值，学习了 Object.keys() 办法和 Object.values() 办法。
