实现效果如图
数据格式如下:
pps: [{"code":"6","createTime":"2018-09-07 00:00:00","des":"可选择居住情况","id":"6","key":"liveType","multi":false,"name":"居住情况","no":1,"status":1,"updateTime":"2018-09-07 00:00:00","usages":["condition"],"values":[{"code":"6.1","createTime":"2018-09-07 00:00:00","id":"601","name":"纯老人家庭","no":1,"propertyId":"6","status":1,"updateTime":"2018-09-27 16:53:57"},{"code":"6.3","createTime":"2018-09-07 00:00:00","id":"603","name":"独居老人","no":3,"propertyId":"6","status":1,"updateTime":"2018-09-27 16:54:06"}]},{"code":"f","createTime":"2018-09-07 00:00:00","des":"老人经济状况","id":"15","multi":true,"name":"经济状况","no":2,"status":1,"updateTime":"2018-09-07 00:00:00","usages":["condition"],"values":[{"code":"f.1","createTime":"2018-09-29 14:18:30","id":"1501","name":"低保","no":1,"propertyId":"15","status":1,"updateTime":"2018-09-29 14:18:30"},{"code":"f.2","createTime":"2018-09-29 14:18:36","id":"1502","name":"低收入","no":2,"propertyId":"15","status":1,"updateTime":"2018-09-29 14:18:36"}]}]
核心代码如下:
数据请求并初始化
API.property.listByUsage(this.usage).then(res => { console.log(‘got properties‘, res.data) // const data = res.data.data var pps = res.data.data if (this.multi) { for (var i = 0; i < pps.length; i++) { var propCode = pps[i].code if (!this.result[propCode]) { this.$set(this.result, propCode, []) this.$set(this.checkAll, propCode, false) // this.result[propCode] = [] } } } this.pps = pps console.log(‘pps:‘, JSON.stringify(this.pps)) })
数据加工方法如下:
cheakLength(code) { for (var i = 0; i < this.pps.length; i++) { if (this.pps[i].code === code) { if (this.result[code].length === this.pps[i].values.length) { this.checkAll[code] = true } else { this.checkAll[code] = false } } } }, handleCheckAllChangeProps(code) { var ppsValues = [] for (var i = 0; i < this.pps.length; i++) { if (this.pps[i].code === code) { this.pps[i].values for (var j = 0; j < this.pps[i].values.length; j++) { ppsValues.push(this.pps[i].values[j].code) } this.result[code] = this.checkAll[code] ? ppsValues : [] } } }, handleCheckAllChange(val) { const streetValue = [] for (var i = 0; i < this.streetsList.length; i++) { streetValue.push(this.streetsList[i].value) } this.streets = val ? streetValue : [] this.streetIsIndeterminate = false },
数据渲染pug格式参考el-checkbox 全选:
.col-12.py-2.df-row-as-jsta .d-inline-block.label.mr-3.text-right 所属街道: el-checkbox(:indeterminate="streetIsIndeterminate", v-model="streetCheckAll", @change="handleCheckAllChange") 全选 el-checkbox-group.ml-4(v-model="streets") el-checkbox(v-for="item in streetsList", :key="item.value", :label="item.value", :value="item.value") {{ item.name}} .col-12.py-2.df-row-as-jsta(v-for=‘prop in pps‘ :key="prop.code") .d-inline-block.label.mr-3.text-right {{ prop.name }}: el-checkbox.mr-3(v-model="checkAll[prop.code]" @change="handleCheckAllChangeProps(prop.code)") 全部 el-checkbox-group.d-inline-block.d-flex.flex-row.flex-wrap(v-model="result[prop.code]", @change="cheakLength(prop.code)") el-checkbox(v-for="item in prop.values" :key="item.code" :label="item.code") {{ item.name}}
粗体为核心代码
