Vue+EleMentUI实现el-table-colum表格select下拉框可编辑

说明：

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

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" clearablev-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.dataif (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 = rowif(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.supplierIdreturn}}},

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 : 0const res = await this.$http({url: `/purchase/purchasesinboundorder/update`,method: 'post',data: this.$http.adornData(row)});let data = res.dataif (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-focus

directives: {// 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()}}},
