Question

我正在尝试遵循此页面示例： https://ant.design/components/table/

精确的蚂蚁过滤样品

我有一列，我只知道它的两个可能值。我可以在调试器中看到执行了handlechange事件，但是在过滤器中单击“确定”后，该表并未得到应有的过滤

我最好的猜测是我在OnFilter事件中遗漏了一些东西

import React, { Component } from 'react';
import {  Table, Tag, Button} from 'antd';

            sortedInfo: null,
        };
        this.handleChange= this.handleChange.bind(this);
        this.clearFilters= this.clearFilters.bind(this);

    }

Answer 1

您需要在fetchData函数中执行handleChange函数。将过滤器参数添加到ajax请求。就是这样：

  handleTableChange = (pagination, filters, sorter) => {
    const pager = { ...this.state.pagination };
    pager.current = pagination.current;
    this.setState({
      pagination: pager,
    });
    this.fetch({
      results: pagination.pageSize,
      page: pagination.current,
      sortField: sorter.field,
      sortOrder: sorter.order,
      ...filters,
    });
  }

Answer 2

在您的SiteType列中，您错误地将filteredValue属性设置为filteredInfo.name。但是过滤器不在name列上，而是在SiteType列上。

将此行更改为：

filteredValue: filteredInfo.name || null,

收件人：

filteredValue: filteredInfo.SiteType || null,

应该没事的。

Antd过滤无法正常工作，客户端代码已执行，但没有过滤快乐
