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" 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-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()
}
}
},
