# Javascript Javascript (no framework)

ActiveWidgets offers javascript components in @activewidgets/js 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/js to your project dependencies -

> npm i --save @activewidgets/js

# Usage

Import mount function into your app -

import { mount } from "@activewidgets/js";

Now, assuming that you've added a placeholder ax-datagrid tag to the page

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

Mount an actual ActiveWidgets component at the placeholder position -

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

mount('ax-datagrid', { rows });

For quick prototyping the package is also available over ActiveWidgets CDN -

<script src="https://cdn.activewidgets.com/js"></script>

In this case the mount function is available at ActiveWidgets.JS global namespace.

var mount = ActiveWidgets.JS.mount;

var rows = [
    { framework: 'none', source: 'CDN', language: 'ES5'}
];

mount('ax-datagrid', { rows: rows });

# Mount function

The first argument for the mount function should be the target element (or selector). The second argument is a properties object. The target element tagName defines the component ID.

mount('#grid1', { columns, rows });

The placeholder element tag must be ax-datagrid

<ax-datagrid id="grid1"></ax-datagrid>

The mount function returns update and destroy methods.

const { update } = mount('#my-grid', { columns, rows });

//...

update({ rows: newRows });

# 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;

mount('ax-datagrid', { columns, rows });

# 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!`);
}

mount('ax-datagrid', { onMouse, columns, rows }); // put event handlers together with props
