# jQuery jQuery

ActiveWidgets integrates with jQuery for legacy / no-framework environments with @activewidgets/jquery package.

ATTENTION!

This package requires dependencies under ⚠️ FREE TRIAL/COMMERCIAL license. You have to purchase a license for each developer in your team before including this package in your application.

# Installation

Add @activewidgets/jquery to your project dependencies -

> npm i --save @activewidgets/jquery

# Usage

Import the library into your app -

import "@activewidgets/jquery";

It will add mount function to jQuery. Now, assuming that you've added a placeholder ax-datagrid tag to the page

<ax-datagrid>Loading...</ax-datagrid>

Assign properties and mount an actual ActiveWidgets component at the placeholder position -

const rows = [
    { message: 'Hello, World!' }
];

$('ax-datagrid')
    .prop('rows', rows)
    .mount();

# Mount function

The mount function does not require any arguments - it uses element tagName as a component ID.

<ax-datagrid id="my-grid-1"> ... </ax-datagrid>

You can apply any selector to find the placeholder element (but the tag must be ax-datagrid)

$('#my-grid-1')
    .prop('rows', rows)
    .mount();

# Data properties

You have to provide columns and rows properties to the datagrid to show some data. The properties of each column object define how the data will be rendered -

  • field - where the cell data comes from (string|function)
  • header - column header (string|object)
  • width - column width (number, in pixels)
  • align - cell text alignment (left|right|center)
  • format - number/date format (string|function)
  • fixed - fixed (true/false) for columns on the left or right side

The style (string|object) or className properties allow to change the styling of the column and cell elements.

const columns = [
  {header: 'Code', field: 'customerID', width: 80, style: 'background:#def', fixed: true},
  {header: 'Company Name', field: 'companyName', width: 160},
  {header: 'Contact', field: 'contactName', width: 120},
  {header: 'Title', field: 'contactTitle', width: 120},
  {header: 'Address', field: 'address', width: 120, align: 'right'}
];

const rows = northwind.customers;

$('ax-datagrid')
    .prop({ columns, rows })  // use $.prop() to assign properties
    .mount();

# User events

In addition to the standard DOM keyboard and mouse events the datagrid emits composite mouse event which makes it easier to find the elements affected by the user action.

function onMouse({row}){
    alert(`row ${row.key} clicked!`);
}

$('ax-datagrid')
    .prop({ columns, rows })
    .on('mouse', event => onMouse(event.detail))  // pass event.detail to your handler
    .mount();

When assigning an event handler, note that the event data is passed in the event.detail property (we are using DOM CustomEvent class).

ActiveWidgets custom events do not bubble, so you should always add an event handler at the component itself, not at some parent element.
