How to use:

Simple case:

import ReactFilterBox, {SimpleResultProcessing} from "react-filter-box";
import "react-filter-box/lib/react-filter-box.css"


export default class App extends React.Component {
    
    constructor(props){
        super(props);

         this.options = [
            {
                columnField: "Name",
                type:"text"
            },
            {
                columnField: "Description",
                type:"text"
            },
            {
                columnField: "Status",
                type:"selection" // when using type selection, it will automatically sugest all posible values
            },
            {
                columnText: "Email @",
                columnField: "Email",
                type:"text"
            }
        ];
    }

    onParseOk(expressions){
        var data = [];
        var newData = new SimpleResultProcessing(this.options).process(data,expressions);
        //your new data here, which is filtered out of the box by SimpleResultProcessing
    }

    render(){
         return <div className="main-container"> 
                    <h2>React Filter Box</h2>
         
                        <ReactFilterBox 
                            
                            data={data}
                            options={this.options}
                            onParseOk={this.onParseOk.bind(this)}
                            />
                    
                    </div>
    }
}

Properties

query:string: binding your text to query of Component

options:Option[]: array of option which helps to construct AutoComplete information.

export interface Option {
    columnField:string; // required
    columnText?:string; // optional
    type: string; // require "text" or "selection"
}

data: any[]: (optional) data is used to construct AutoComplete only if
you specify in options with type = "selection", which it will
show all posibles values get from data

Events

onChange(query: String, expressions: Expression[]|Error): event raised every change of
query, together with expressions if parse is ok, otherwise is error

interface Expression {
    conditionType?: "OR" | "AND";
    category?: string;
    operator?: string;
    value?: string;
    expressions?:Expression[];    
}

to see more about the structure of Expression which parsed from query, please
take a look at: unit test

onParseOk(expressions:Expression[]): event raised when parsing is ok

onParseError(error:Error): event raised when parsing error

Custom Functions

customRenderCompletionItem(self:HintResult,data:Completion, registerAndGetPickFunc:Function): ReactComponent:
provide your custom AutoComplete Rendering for each Item.

  • self:HintResult: ignore for now
  • data:Completion:
export interface Completion{
    value:string | Object; // Your value as text, Object if your custom AutoCompleteHandler return Object
    type?:string;    // "catetory" or "value" or "operator" or "literal"
}
  • registerAndGetPickFunc:Function: you only call this function in case you want
    to handle the way user wants to select your value in AutoComplete popup.

In default behavior, user will press enter to select an item.
But if for example, your component is DatePicker, and you want user to select any date,
by clicking on your component, in order to achive that, you must call this method to
register with system you want to handle this by yourself.

This method will return another function ** (value:string):void **, which you can call it
and provide the value will be inserted into query.

You can look into file demo3.js for detail

autoCompleteHandler: BaseAutoCompleteHandler
