Installation
添加 @activewidgets/preact到您的项目依赖项 -
> npm i --save @activewidgets/preact
Usage
现在您可以导入 ActiveWidgets 组件类 -
import { Datagrid } from "@activewidgets/preact";
并将它们用作任何标准 Preact 组件。
import { h, render } from 'preact';
import { Datagrid } from '@activewidgets/preact';
import './styles.css';
const rows = [
{ message: 'Hello, World!' }
];

CDN links
为了快速制作原型,该包也可通过 ActiveWidgets CDN 获得-
<script src="https://cdn.activewidgets.com/preact"></script>
在这种情况下,您将在 ActiveWidgets.Preact
全局命名空间中找到组件。
var Datagrid = ActiveWidgets.Preact.Datagrid;
var rows = [
{ framework: 'preact', source: 'CDN', language: 'ES5'}
];
var App = preact.h(Datagrid, {rows: rows});
preact.render(App, document.getElementById("app"));

Data properties
你必须提供 columns 和 rows 数据网格的属性显示一些数据。 每个 column
对象的属性定义了数据的呈现方式 -
- 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
style
(字符串|对象)或 className
属性允许更改样式列和单元格元素。
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;
function App(){
return <Datagrid columns={columns} rows={rows} />
}

User events
除了数据网格发出的标准 DOM 键盘和鼠标事件合成的 mouse 事件,可以更轻松地找到受用户操作影响的元素 -
function onMouse({row, column}){
alert(`row ${row.key} clicked!`);
}
function App(){
return <Datagrid onMouse={onMouse} columns={columns} rows={rows} />
}

Usage
Now you can import ActiveWidgets component classes -
import { Datagrid } from "@activewidgets/preact";
and use them as any standard Preact component.
import { h, render } from 'preact';
import { Datagrid } from '@activewidgets/preact';
import './styles.css';

CDN links
For quick prototyping the package is also available over ActiveWidgets CDN -
<script src="https://cdn.activewidgets.com/preact"></script>
In this case you will find the components at ActiveWidgets.Preact
global namespace.
var Datagrid = ActiveWidgets.Preact.Datagrid;
var rows = [
{ framework: 'preact', source: 'CDN', language: 'ES5'}
];
var App = preact.h(Datagrid, {rows: rows});
preact.render(App, document.getElementById("app"));

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;
function App(){
return <Datagrid columns={columns} rows={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, column}){
alert(`row ${row.key} clicked!`);
}
function App(){
return <Datagrid onMouse={onMouse} columns={columns} rows={rows} />
}
