React Data Grid Multiselect过滤器对齐问题

标签: javascript css reactjs react-data-grid

当我们在React Data Grid中选择多个过滤器选项时,列标题会变得混乱。 有没有办法解决此问题,以便所选的筛选器选项显示在a中的一行上方 下拉列表而不是添加到列标题。随着新的过滤器键添加到列表中,列标题大小也在增长。

```

import React from 'react';

var ExecutionEnvironment = require('exenv');

if (ExecutionEnvironment.canUseDOM) {
  var ReactDataGrid = require('react-data-grid');
  var { Toolbar, Filters: { NumericFilter, AutoCompleteFilter, MultiSelectFilter, SingleSelectFilter }, Data: { Selectors } } = require('react-data-grid-addons');
}

export default class ReactGrid extends React.Component {
  constructor(props, context) {
    const { Toolbar, Filters: { NumericFilter, AutoCompleteFilter, MultiSelectFilter, SingleSelectFilter }, Data: { Selectors } } = require('react-data-grid-addons');
    super(props, context);

    this._columns = [
      {
        key: 'prd_family_name',
        name: 'Product Family Name',
        width: 190,
        filterable: true,
        filterRenderer: MultiSelectFilter,
        sortable: true
      },
      {
        key: 'prd_family_mkt',
        name: 'Market',
        width: 70,
        filterable: true,
        filterRenderer: AutoCompleteFilter,
        sortable: true
      }
    ];
    console.log(`gridvalue${this.props.gridValues}`);
    this.state = { filters: {} };
  }

  componentWillReceiveProps(nextProps) {
    this.setState({ rows: nextProps.gridValues });
  }

  getRandomDate = (start, end) => new Date(start.getTime() + Math.random() * (end.getTime() - start.getTime())).toLocaleDateString();

  rowGetter = index => Selectors.getRows(this.state)[index];

  rowsCount = () => Selectors.getRows(this.state).length;

  handleFilterChange = (filter) => {
    const newFilters = Object.assign({}, this.state.filters);
    if (filter.filterTerm) {
      newFilters[filter.column.key] = filter;
    } else {
      delete newFilters[filter.column.key];
    }
    this.setState({ filters: newFilters });
  };

  getValidFilterValues = (columnId) => {
    const values = this.state.rows.map(r => r[columnId]);
    return values.filter((item, i, a) => i === a.indexOf(item));
  };

  handleOnClearFilters = () => {
    this.setState({ filters: {} });
  };

  handleGridSort = (sortColumn, sortDirection) => {
    const comparer = (a, b) => {
      if (sortDirection === 'ASC') {
        return (a[sortColumn] > b[sortColumn]) ? 1 : -1;
      } else if (sortDirection === 'DESC') {
        return (a[sortColumn] < b[sortColumn]) ? 1 : -1;
      }
    };

    const rows = sortDirection === 'NONE' ? this.state.originalRows.slice(0) : this.state.rows.sort(comparer);

    this.setState({ rows });
  };

  render() {
    return (
      <ReactDataGrid
        enableCellSelect
        columns={this._columns}
        rowGetter={this.rowGetter}
        rowsCount={this.rowsCount()}
        onGridSort={this.handleGridSort}
        minHeight={450}
        toolbar={<Toolbar enableFilter />}
        onAddFilter={this.handleFilterChange}
        getValidFilterValues={this.getValidFilterValues}
        onClearFilters={this.handleOnClearFilters}
      />);
  }
}

```

以上代码用于渲染数据网格。

我看到了完全相同的问题。我已经对一堆CSS进行了排序,当你将鼠标移过时,它会破坏过滤器中的过滤器选择。

Filter on mouse over

当鼠标移出时,它会回到水平布局并且溢出被剪裁。不是100%完美,但似乎对我来说做得很好。

您需要调整CSS中的一些值以使用您的字体/大小,但这应该是微不足道的。
