神思者 ·上个小节我们用Swagger测试了后端返回的分页数据，这节课咱们应该把分页数据显示到前端页面。违纪罚款页面以表格为主，所以排版布局较为传统，跟用户管理、部门管理页面类似。
一、熟悉前端页面
打开amect.vue文件，还是老规矩，看视图层标签之前，咱们先来看看模型层都定义了哪些变量。
data: function() {
return {
dataForm: {
name: null,
deptId: null,
typeId: null,
status: null,
date: null
},
deptList: [],
amectTypeList: [],
dataList: [],
pageIndex: 1,
pageSize: 10,
totalCount: 0,
dataListLoading: false,
dataListSelections: [],
dataRule: {
name: [{ required: false, pattern: '^[\u4e00-\u9fa5]{1,10}$', message: '姓名格式错误' }]
},
addOrUpdateVisible: false,
payVisible: false
};
},
视图层里面的查询条件较多，部门列表、违纪类型列表的数据，都是要通过Ajax查询出来的，所以建议大家可以看看loadDeptList()和loadAmectTypeList()函数。
<el-form :inline="true" :model="dataForm" :rules="dataRule" ref="dataForm">
<el-form-item prop="name">
<el-input
v-model="dataForm.name"
placeholder="姓名"
size="medium"
class="input"
clearable="clearable"
/>
</el-form-item>
<el-form-item>
<el-select
v-model="dataForm.deptId"
class="input"
placeholder="部门"
size="medium"
clearable="clearable"
>
<el-option v-for="one in deptList" :label="one.deptName" :value="one.id" />
</el-select>
</el-form-item>
<el-form-item>
<el-select
v-model="dataForm.typeId"
class="input"
placeholder="罚款类型"
size="medium"
clearable="clearable"
>
<el-option v-for="one in amectTypeList" :label="one.type" :value="one.id" />
</el-select>
</el-form-item>
<el-form-item>
<el-date-picker
v-model="dataForm.date"
type="daterange"
range-separator="~"
start-placeholder="开始日期"
end-placeholder="结束日期"
size="medium"
></el-date-picker>
</el-form-item>
<el-form-item>
<el-select
v-model="dataForm.status"
class="input"
placeholder="状态"
size="medium"
clearable="clearable"
>
<el-option label="未缴纳" value="1" />
<el-option label="已缴纳" value="2" />
</el-select>
</el-form-item>
<el-form-item>
<el-button size="medium" type="primary" @click="searchHandle()">查询</el-button>
<el-button
size="medium"
type="primary"
:disabled="!isAuth(['ROOT', 'AMECT:INSERT'])"
@click="addHandle()"
>
新增
</el-button>
<el-button
size="medium"
type="danger"
:disabled="!isAuth(['ROOT', 'AMECT:DELETE'])"
@click="deleteHandle()"
>
批量删除
</el-button>
<el-button
size="medium"
type="warning"
:disabled="!isAuth(['ROOT', 'AMECT:SELECT'])"
@click="reportHandle()"
>
查看报告
</el-button>
</el-form-item>
</el-form>
页面表格内容也不复杂，而且折叠面板的内容，我们直接把tb_amect数据表中的reason字段值写上去就可以了，不需要展开的时候发送Ajax请求。
<el-table
:data="dataList"
border
v-loading="dataListLoading"
@selection-change="selectionChangeHandle"
cell-style="padding: 4px 0"
style="width: 100%;"
size="medium"
>
<el-table-column
type="selection"
:selectable="selectable"
header-align="center"
align="center"
width="50"
/>
<el-table-column width="40px" prop="reason" header-align="center" align="center" type="expand">
<template #default="scope">
罚款原因：{{ scope.row.reason }}
</template>
</el-table-column>
<el-table-column type="index" header-align="center" align="center" width="100" label="序号">
<template #default="scope">
<span>{{ (pageIndex - 1) * pageSize + scope.$index + 1 }}</span>
</template>
</el-table-column>
<el-table-column prop="type" header-align="center" align="center" label="罚款类型" />
<el-table-column prop="name" header-align="center" align="center" label="当事人" />
<el-table-column prop="deptName" header-align="center" align="center" label="所属部门" />
<el-table-column header-align="center" align="center" label="罚款金额">
<template #default="scope">
<span>{{ scope.row.amount }}元</span>
</template>
</el-table-column>
<el-table-column prop="status" header-align="center" align="center" label="状态" />
<el-table-column prop="createTime" header-align="center" align="center" label="日期时间" />
<el-table-column fixed="right" header-align="center" align="center" width="150" label="操作">
<template #default="scope">
<el-button
type="text"
size="medium"
:disabled="!(isAuth(['ROOT', 'AMECT:UPDATE']) && scope.row.status != '已缴纳')"
@click="updateHandle(scope.row.id)"
>
修改
</el-button>
<el-button
type="text"
size="medium"
:disabled="!(isAuth(['ROOT', 'AMECT:DELETE']) && scope.row.status != '已缴纳')"
@click="deleteHandle(scope.row.id)"
>
删除
</el-button>
<el-button
type="text"
size="medium"
:disabled="!(scope.row.mine == 'true' && scope.row.status == '未缴纳')"
@click="payHandle(scope.row.id)"
>
交款
</el-button>
</template>
</el-table-column>
</el-table>
二、加载页面数据
大家看好了，这才是你要写的代码，我们在amect.vue页面中，声明加载罚款记录的封装方法。
loadDataList: function() {
let that = this;
that.dataListLoading = true;
let data = {
name: that.dataForm.name,
deptId: that.dataForm.deptId,
typeId: that.dataForm.typeId,
status: that.dataForm.status,
page: that.pageIndex,
length: that.pageSize
};
if (that.dataForm.date != null && that.dataForm.date.length == 2) {
let startDate = that.dataForm.date[0];
let endDate = that.dataForm.date[1];
data.startDate = dayjs(startDate).format('YYYY-MM-DD');
data.endDate = dayjs(endDate).format('YYYY-MM-DD');
}
that.$http('amect/searchAmectByPage', 'POST', data, true, function(resp) {
let page = resp.page;
for (let one of page.list) {
if (one.status == 1) {
one.status = '未缴纳';
} else if (one.status == 2) {
one.status = '已缴纳';
}
}
that.dataList = page.list;
that.totalCount = page.totalCount;
that.dataListLoading = false;
});
},
然后在本页面的生命周期函数create()中调用loadDataList()，实现进入页面就在表格中加载无条件查询的第一页会议室记录。
created: function() {
……
this.loadDataList();
}
为分页控件设置翻页和改变显示记录数量的回调函数。
<el-pagination
@size-change="sizeChangeHandle"
@current-change="currentChangeHandle"
:current-page="pageIndex"
:page-sizes="[10, 20, 50]"
:page-size="pageSize"
:total="totalCount"
layout="total, sizes, prev, pager, next, jumper"
></el-pagination>
sizeChangeHandle: function(val) {
this.pageSize = val;
this.pageIndex = 1;
this.loadDataList();
},
currentChangeHandle: function(val) {
this.pageIndex = val;
this.loadDataList();
},
三、有条件查询数据
我们声明查询按钮点击事件对应的回调函数，写完这个函数大家就可以运行前后端项目，测试一下数据的查询和分页效果。
searchHandle: function() {
this.$refs['dataForm'].validate(valid => {
if (valid) {
this.$refs['dataForm'].clearValidate();
if (this.dataForm.name == '') {
this.dataForm.name = null;
}
if (this.pageIndex != 1) {
this.pageIndex = 1;
}
this.loadDataList();
} else {
return false;
}
});
},
