在进行采购入库的过程中，有必要对表格中的一行进行快速编辑保存，节省时间，提高工作效率！，而不是每次编辑都要弹窗才可编辑 源码：https://gitee.com/charlinchenlin/store-pos

效果图：

1、在data定义supplier数组等元素data() { return { suppliers:[], //保存供应商数据 showInput: "", //用来判断是否显示哪个单元格 oldData: {}, //用来存修改前的数据 currentData: {}, //用来保存新的数据 } },2、为el-table表格单击和双击添加tableDbEdit事件<el-table :data="dataList" size="mini" v-loading="dataListLoading" @selection-change="selectionChangeHandle" style="width: 100%;" @cell-click="tableDbEdit" @cell-dblclick="tableDbEdit" height="320" :header-cell-style="{ background: '#fcfcfc', color: '#606266', height:'36px'}"> <el-table-column type="selection" header-align="center" align="center" width="50"> </el-table-column> ------ </el-table>

控制是否显示select下拉框

tableDbEdit(row, column, event) { this.showInput = column.property + row.inboundId; this.oldData[column.property] = row[column.property]; },3、为供应商列添加下拉框

如果showInput的值与当前的inboundId相同，则显示下拉选项，否则显示数据信息

<el-table-column prop="supplierName" header-align="center" align="center" label="供应商名称" width="150" show-overflow-tooltip> <template slot-scope="scope"> <el-select size="mini" @focus="getSuppliers()" @click="getSuppliers()" @change='blurInput(scope.row, "supplierName", scope.row.supplierName)' v-model="scope.row.supplierName" clearable v-if="showInput == `supplierName${scope.row.inboundId}`" placeholder="请选择"> <el-option v-for="item in suppliers" :key="item.supplierId" :label="item.supplierName" :value="item.supplierName"> </el-option> </el-select> <span v-else class="active-input">{{scope.row.supplierName}}</span> </template></el-table-column>

聚焦或单击时获取供应商数据

async getSuppliers() { const res = await this.$http({ url: `/product/supplier/getSupplies`, method: 'get', params: this.$http.adornParams() }) let data = res.data if (data && data.code === 0) { this.suppliers = data.data } },

触发change事件时给当前列赋值，并设置供应商信息

// 当input失去光标后进行的操作 async blurInput(row, name, value) { // 判断数据是否有所改变，如果数据有改变则调用修改接口 if (this.oldData[name] != value) { row[name] = value } this.showInput = "" this.currentData = row if(name === 'supplierName'){ this.setSuppliers(row) } },setSuppliers(row) { for (let index in this.suppliers) { let item = this.suppliers[index] if (row.supplierName === item.supplierName) { row.supplierId = item.supplierId return } } },4、保存当前列，成功后重新加载数据async saveHandle(row) { console.log("saveHandle row===", row) row.status = row.status ? 1 : 0 const res = await this.$http({ url: `/purchase/purchasesinboundorder/update`, method: 'post', data: this.$http.adornData(row) }); let data = res.data if (data && data.code !== 0) { row.status = !row.status; return this.$message.error('修改失败!'); } this.$message.success('更新成功！'); this.getDataList(); },5、定义v-focusdirectives: { // 通过自定义指令实现的表单自动获得光标的操作 focus: { inserted: function(el) { if (el.tagName.toLocaleLowerCase() == "input") { el.focus() } else { if (el.getElementsByTagName("input")) { el.getElementsByTagName("input")[0].focus() } } el.focus() } }, focusTextarea: { inserted: function(el) { if (el.tagName.toLocaleLowerCase() == "textarea") { el.focus() } else { if (el.getElementsByTagName("textarea")) { el.getElementsByTagName("textarea")[0].focus() } } el.focus() } } },
