Filtering

Quick start

From version 2.0 revo-grid supports Filtering Plugin.
To enable Filtering just setup property filter to true.
By default there are sevaral types available:

• string
  • notEmpty
  • empty
  • eq
  • notEq
  • begins
  • contains
  • notContains
• number
  • notEmpty
  • empty
  • eqN
  • neqN
  • gt
  • gte
  • lt
  • lte

With their names accordingly:

  const filterNames = {
    none: 'None',
    empty: 'Not set',
    notEmpty: 'Set',

    eq: 'Equal',
    notEq: 'Not equal',
    begins: 'Begins with',
    contains: 'Contains',
    notContains: 'Does not contain',

    eqN: '=',
    neqN: '!=',
    gt: '>',
    gte: '>=',
    lt: '<',
    lte: '<=',
};

// tsx
const columns = [{ prop: 'name' }];
const source = [{ name: 'Steve' }, { name: 'John' }];
return '<revo-grid rowClass="myRowClass" source={source} columns={columns} filter={true}/>';

Filter per column

If you wish to disable filter for selected column all you have to do setup filter on your column to false.

const columns = [{ prop: 'name', filter: false }]; // filter icon will be disabled for column with property `name`
const source = [{ name: 'Steve' }];
return '<revo-grid rowClass="myRowClass" source={source} columns={columns} filter={true}/>';

Alternatively you can setup filter type filter: 'number':

// tsx
const columns = [{ prop: 'name', filter: 'number' }]; // filter type 'number' (string by default)
const source = [{ name: 'Steve' }];
return '<revo-grid rowClass="myRowClass" source={source} columns={columns} filter={true}/>';

Advance usage

If you consider more advanced filter usage you have to look into <revo-grid/> filter property. filter: boolean|ColumnFilterConfig - can be boolean or ColumnFilterConfig type.

type ColumnFilterConfig = {
  // preserved filters collection
  collection?: FilterCollection;
  // names of filters to be included include = ['eq', 'contains']
  include?: string[];
  // you can create your own filters here
  customFilters?: Record<string, CustomFilter>;
};

Advance filter usage:

const columns = [{ prop: 'name', filter: 'myFilterType' }];
const source = [{ name: 'Steve' }];

// @extraValue available if filterFunc.extra set to input
const filterFunc = (cellValue, extraValue) => {
    if (!cellValue) {
        return false;
    }
    if (typeof cellValue !== 'string') {
      cellValue = JSON.stringify(cellValue);
    }
    return cellValue === 'A';
};
// if you want extra input field for @extraValue
filterFunc.extra = 'input';

const filterConfig = {
  include: ['newEqual'],
  customFilters: {
    'newEqual': {
      columnFilterType: 'myFilterType', // column filter type id
      name: 'Equal to A',
      func: filterFunc
    }
  }
};
return '<revo-grid rowClass="myRowClass" source={source} columns={columns} filter={filterConfig}/>';

TIP

ColumnFilterConfig is powerful option for the latest information it's recommended to read filter-plugin file for better understanding what parameters filter accepts.
