调用方法:Vue.set( target, key, value ) target:要更改的数据源(可以是对象或者数组) key:要更改的具体数据 value :重新赋的值
具体用法
js代码:
//设置初始状态和值
let j = { id: 0, "progressTime": "", "progressContent": "", "isSet": true, "_temporary": true };
_this.tableInFormData = []
//将对象加入到数组
this.tableInFormData.push(j);
//项目将isSet变为true 从而v-if来判断输入框可以使用
_this.$set(_this.tableInFormData[index],"isSet",true)
下面放html代码:
<el-table-column label="时间" width="300" :show-overflow-tooltip="true"> <template slot-scope="scope" > <span v-if="scope.row.isSet"> <el-date-picker v-model="form2.progressTime" type="datetime" :picker-options="pickerBeginDateBefore" format="yyyy-MM-dd HH:mm:ss" value-format="yyyy-MM-dd HH:mm:ss" placeholder="选择日期"> <!--:disabled="true">--> </el-date-picker> </span> <span v-else>{{changeTimeToDate(scope.row.ProgressTime) }}</span> </template> </el-table-column> <el-table-column prop="ProgressContent" label="处置进展" :show-overflow-tooltip="true"> <template slot-scope="scope"> <span v-if="scope.row.isSet"> <el-input size="small" v-model="form2.progressContent" placeholder="请输入内容" ></el-input> </span> <span v-else>{{(scope.row.ProgressContent) }}</span> </template> </el-table-column>
