效果图：
点击新增后跳转到新增页面
新增：
// 新增 / 修改
addOrUpdateHandle (id) {
this.$router.push({
name: 'backUseinfo',
params: {
id: id,
disable: false
}
})
// this.addOrUpdateVisible = true
// this.$nextTick(() => {
// this.$refs.addOrUpdate.init(id)
// })
},这里是在router中新增了路由
一点击新增就路由跳转到了一个新的页面
效果图如下，点击保存之后，要把这张表里所有的信息都弄到跳转之前的那个表里去。
上部分是需要填写的表单
下部分是一个表格需要填写
表单部分

</div>
</el-form>表格部分（我简写了，这个表分为两部分，一部分是购买记录表，一部分是使用去向表）
如何在表格里合并单元格呢，在<el-table-column>里嵌套<el-table-column>即可
<el-table
:data="dataForm.details"
@selection-change="selectionChangeHandle"
:default-sort="{ prop: 'date', order: 'descending' }"
>
<el-table-column type="selection" width="55"> </el-table-column>
<el-table-column
prop="id"
align="center"
label="农药购买记录"
width="150"
>
<el-table-column align="center" type="index" width="50">
</el-table-column>
<el-table-column
prop="purchaseDate"
align="center"
label="日期"
width="140"
>
<template slot-scope="scope">
<el-date-picker
v-model="scope.row.purchaseDate"
type="date"
placeholder="日期"
:disabled="disabled"
style="width: 100%"
format="MM-dd"
value-format="yyyy-MM-dd HH:mm:ss"
>
</el-date-picker>
</template>
</el-table-column>
</el-table-column>
<el-table-column
prop="name"
align="center"
label="农药使用去向记录"
width="180"
>
<el-table-column
prop="medicationDate"
align="center"
label="用药日期"
width="180"
>
<template slot-scope="scope">
<el-date-picker
v-model="scope.row.medicationDate"
type="date"
placeholder="播种日期"
:disabled="disabled"
style="width: 100%"
format="MM-dd"
value-format="yyyy-MM-dd HH:mm:ss"
>
</el-date-picker>
</template>
</el-table-column>
</el-table-column>
</el-table>data声明部分
data () {
return {
isnewone: false,
disabled: false,
visible: false,
dataForm: {
id: 0,
farmerId: '',
dateyear: '',
taskId: ''
},
detail: {
id: '',
purchaseDate: '',
pdNo: '',
commonName: '',
purchaseAmount: '',
purchaseCost: '',
packagings: '',
packingSpecification: '',
medicationDate: '',
cropId: '',
controlObject: '',
medicationArea: '',
totalDosage: '',
},
}
},然后我们来看新增记录addOneLine方法
一开始底部的数据其实应该是无数据的，点击新增，会有一条数据
addOneLine () {
let data = this.dataForm
// data.details.push(JSON.parse(JSON.stringify(this.detail)))
let details = this.dataForm.details
data.details.push(JSON.parse(JSON.stringify(this.detail)))
},但是这里需要设定的是只要一进入这个页面，就需要看到一行新增待填数据
所以这里写一个init方法
init (id, disabled) {
this.disabled = disabled
this.dataForm.id = id || ''
this.visible = true
this.$nextTick(() => {
this.$refs['dataForm'].resetFields()
//判断是修改还是新增
if (this.dataForm.id) {
this.$http({
url: `/pesticide/useinfo/info/${this.dataForm.id}`,
method: 'get'
}).then(({ data }) => {
if (data && data.code === 0) {
this.dataForm = data.useinfo
// console.log(data.useinfo);
// console.log(this.dataForm, 5555555555555555);
}
})
} else {
//如果是新增就 插入一条空数据（dataForm.details [detail]）
//插入一条空数据怎么写呢
//
// this.dataForm = this.dataForm.details [this.detail]
// <template slot-scope="scope">
// {
{(scope.row.id)}}
// </template>
// debugger
let data = JSON.parse(JSON.stringify(this.dataForm))
let details = []
details.push(JSON.parse(JSON.stringify(this.detail)))
details = details.map(item => {
// 由于农药中文输入框的value改成整条数据，所以初始化时commonName也应该是一个对象
return { ...item, commonName: { commonName: item.commonName, pdNo: item.pdNo } }
})
data.details = details
this.dataForm = data
// this.dataForm.details = []
// this.dataForm.details.push(JSON.parse(JSON.stringify(this.detail)))
// console.log(this.dataForm);
}
})
},然后点击填写数据点击保存
// 表单提交
dataFormSubmit () {
this.$refs['dataForm']
.validate((valid) => {
console.log(valid, 1111111111111111111);
if (valid) {
let details = this.dataForm.details
this.$http({
url: `/pesticide/useinfo/${!this.dataForm.id ? 'save' : 'update'}`,
method: 'post',
data: this.dataForm
}).then(({ data }) => {
if (data && data.code === 0) {
this.$message({
message: '操作成功',
type: 'success',
duration: 1500
})
this.visible = false
this.$emit('refreshDataList')
}
})
}
})
},批量删除功能
//删除
deleteHandle () {
// if (rows) {
// rows.forEach((row) => {
// this.$refs.multipleTable.toggleRowSelection(row);
// });
// } else {
// this.$refs.multipleTable.clearSelection();
// }
//首先获取到对象（要删除的对象）
//在获取到整个table里面的数据
//判断是否相等 是的话就删除
let finalData = JSON.parse(JSON.stringify(this.dataForm.details));
let delIds = [];
this.dataListSelections.forEach((item) => {
this.dataForm.details.forEach((tableDataItem, i) => {
// console.log(item == tableDataItem);
if (item == tableDataItem) {
// delete finalData[i];
delIds.push(i);
}
});
});
function sortNumber (a, b) {
//升序
return a - b;
}
delIds.sort(sortNumber);
let delNum = 0;
for (let i = 0; i < delIds.length; i++) {
finalData.splice(delIds[i] - delNum, 1);
delNum++;
}
// delIds.forEach((item) => {
// i = i - 1;
// });
this.dataForm.details = finalData;
},删除单行：
<el-table-column
fixed="right"
header-align="center"
align="center"
width="150"
label="操作"
>
<template slot-scope="scope">
<button @click="addXiaoGou(scope.row)" :disabled="disabled">
添加
</button>
<button
@click="deleteItem(scope.$index, scope.row)"
:disabled="disabled"
type="danger"
>
删除
</button>
</template>
</el-table-column>
//单独删除
deleteItem (index, row) {
console.log(index);
this.$confirm('确定对所选项进行[删除]操作?', '提示', {
confirmButtonText: '确定',
cancelButtonText: '取消',
type: 'warning'
}).then(() => {
this.dataForm.details.splice(index, 1)
// this.dataForm.details.splice(index, 1)
})
},
使用到的是js中的splice()方法
语法：
arr.splice(index,1)，arr是数组
