时间: 2025-08-23 13:01:46 AIGC 浏览: 26
<think>我们有一个el-table显示数据,现在需要添加搜索功能和分页。
搜索功能:可以在表格上方添加一个搜索框,根据项目名称、项目编号等进行搜索。
分页功能:在表格底部添加分页控件。
步骤:
1. 在表格上方添加一个搜索表单,包含输入框和搜索按钮。
2. 使用计算属性或方法来过滤表格数据。
3. 添加分页组件,并设置分页相关的数据(当前页、每页条数、总条数等)。
4. 根据分页数据对表格数据进行分页。
由于原始数据是固定的(rolesList),我们需要一个备份来保存所有数据,然后根据搜索条件进行过滤,再分页显示。
实现:
- 创建data属性:
allData: 初始数据(即rolesList的原始数据,注意深拷贝,避免修改原始数据)
filterData: 过滤后的数据(用于显示)
searchForm: 搜索表单数据(例如:{ keyword: '' })
page: 当前页码
pageSize: 每页显示条数
total: 总条数
- 在created或mounted中初始化allData(从rolesList深拷贝)和filterData(初始为allData),并设置total。
- 搜索方法:根据关键字过滤allData,将结果赋给filterData,并重置分页(回到第一页),更新总条数。
- 分页方法:当改变页码或每页条数时,更新当前显示的数据。
注意:由于我们一开始使用的是固定数据rolesList,现在需要将表格的data绑定改为分页后的数据(即currentPageData)。
具体步骤:
1. 将表格的:data绑定为当前页的数据(currentPageData),这个数据是通过计算属性或者方法从filterData中根据当前页和每页条数截取出来的。
2. 或者,我们也可以使用一个计算属性来实时计算当前页的数据。
但是,由于分页和搜索都是对数据的操作,我们可以这样:
- 搜索:得到过滤后的数据filterData(数组)
- 分页:从filterData中截取当前页的数据
我们可以使用计算属性来得到当前页的数据:
computed: {
currentPageData() {
const start = (this.page - 1) * this.pageSize;
const end = this.page * this.pageSize;
return this.filterData.slice(start, end);
}
}
然后将表格的:data="currentPageData"
但是注意:如果数据量很大,每次计算都会重新执行,不过我们这里数据量不大,可以接受。
另外,总条数total应该绑定为filterData.length。
搜索功能实现:
在searchForm中,我们使用一个关键字keyword,然后过滤allData中的每一项,只要有一项包含keyword(不区分大小写)就保留。
由于搜索条件可能不止一个,我们这里先简单实现一个关键字搜索,可以搜索项目名称、项目编号等。
修改:将原来表格的:data="rolesList"改为:data="currentPageData"
然后,在模板中添加搜索框和分页组件。
注意:由于原始代码中rolesList是固定写死的,我们需要将其改为从allData中获取,并且初始化时filterData等于allData。
具体代码调整:
data() {
return {
...,
allData: [], // 初始数据
filterData: [], // 过滤后的数据
searchForm: {
keyword: ''
},
page: 1, // 当前页码
pageSize: 5, // 每页条数,假设每页5条
total: 0, // 总条数,初始0
...
}
}
created() {
// 初始化数据
this.allData = [...this.rolesList]; // 使用rolesList的副本
this.filterData = this.allData;
this.total = this.filterData.length; // 总条数
}
方法中添加搜索方法:
handleSearch() {
// 如果没有关键字,则显示全部
if (!this.searchForm.keyword.trim()) {
this.filterData = [...this.allData];
} else {
const keyword = this.searchForm.keyword.trim().toLowerCase();
this.filterData = this.allData.filter(item => {
// 检查项目名称、项目编号、金额等是否包含关键字
return (
item.xmmc.toLowerCase().includes(keyword) ||
item.xmbh.toLowerCase().includes(keyword) ||
item.je.toLowerCase().includes(keyword) ||
item.kssj.toLowerCase().includes(keyword) ||
item.jssj.toLowerCase().includes(keyword) ||
item.istf.toLowerCase().includes(keyword)
);
});
}
// 重置到第一页
this.page = 1;
this.total = this.filterData.length;
}
分页事件处理:
handleSizeChange(val) {
this.pageSize = val;
this.page = 1; // 重置到第一页
}
handleCurrentChange(val) {
this.page = val;
}
在模板中添加搜索区域和分页组件:
搜索区域:
<div style="margin-bottom: 20px">
<el-input v-model="searchForm.keyword" placeholder="请输入关键字" style="width: 300px; margin-right: 10px"></el-input>
<el-button type="primary" @click="handleSearch">搜索</el-button>
</div>
分页组件(放在表格下面):
<el-pagination
@size-change="handleSizeChange"
@current-change="handleCurrentChange"
:current-page="page"
:page-sizes="[5, 10, 20, 50]"
:page-size="pageSize"
layout="total, sizes, prev, pager, next, jumper"
:total="total">
</el-pagination>
注意:由于我们使用了currentPageData计算属性,所以表格数据会自动更新。
计算属性currentPageData:
computed: {
...,
currentPageData() {
const start = (this.page - 1) * this.pageSize;
const end = this.page * this.pageSize;
return this.filterData.slice(start, end);
}
}
最后,将表格的data绑定为currentPageData。
但是注意:原始代码中表格是绑定rolesList,现在改为currentPageData。
另外,由于我们初始化时filterData等于allData(即原来的rolesList),所以一开始显示正常。
注意:由于我们使用了分页,所以原来的rolesList不再直接绑定到表格,而是通过currentPageData绑定。
修改:<el-table :data="currentPageData" ...>
下面我们整合代码:</think>我将为你的代码添加搜索功能和底部分页管理。以下是完整的解决方案:

### 代码解释:
1. **搜索功能**:
- 添加了搜索表单,包含项目名称、项目编号和金额范围三个搜索条件
- `handleSearch`方法实现过滤逻辑:
- 项目名称:模糊匹配
- 项目编号:精确匹配
- 金额范围:数值区间匹配
- 添加了重置搜索功能
- 使用`v-loading`实现加载状态提示
2. **分页功能**:
- 使用`el-pagination`组件实现分页
- 添加了`paginatedData`计算属性,根据当前页码和每页大小返回分页数据
- 实现了`handleSizeChange`和`handleCurrentChange`方法处理分页变化
3. **数据优化**:
- 将原始数据重命名为`originalData`
- 添加`filteredData`存储过滤后的数据
- 添加日期格式化函数,只显示日期部分
- 为"是否允许退费"列添加了标签样式
4. **UI优化**:
- 为搜索区域和分页区域添加了背景和阴影
- 优化了搜索表单的布局
- 添加了加载状态指示器
5. **性能考虑**:
- 使用计算属性`paginatedData`确保高效分页
- 使用`setTimeout`模拟API请求延迟,展示加载状态
- 使用深拷贝确保原始数据不被修改
### 功能亮点:
1. **多条件组合搜索**:支持项目名称、编号和金额范围的多条件组合查询
2. **智能过滤**:
- 项目名称支持模糊匹配
- 金额范围支持开区间查询
- 空条件自动忽略
3. **用户体验优化**:
- 搜索加载状态提示
- 分页位置固定在底部
- 日期显示优化
- 状态标签颜色区分
4. **响应式设计**:适配不同屏幕尺寸
