@activewidgets/js 中文文档教程
ActiveWidgets/JS • Datagrid
ActiveWidgets 是一个多框架 UI 组件库。 此软件包为 javascript / 无框架 环境提供datagrid 组件。
Installation
添加 @activewidgets/js到您的项目依赖项 -
> npm i --save @activewidgets/js
Usage
将 mount
函数导入您的应用程序 -
import { mount } from "@activewidgets/js";
现在,假设您已将占位符 ax-datagrid
标记添加到
<ax-datagrid>Loading...</ax-datagrid>
页面占位符位置 -
const rows = [
{ message: 'Hello, World!' }
];
mount('ax-datagrid', { rows });

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/js"></script>
在这种情况下,mount
函数在 ActiveWidgets.JS
全局命名空间中可用。
var mount = ActiveWidgets.JS.mount;
var rows = [
{ framework: 'none', source: 'CDN', language: 'ES5'}
];
mount('ax-datagrid', { rows: rows });

Mount function
mount function 应该是目标元素(或选择器)。 第二个参数是一个属性对象。 目标元素 tagName 定义组件 ID。
mount('#grid1', { columns, rows });
占位符元素标记必须是 ax-datagrid
<ax-datagrid id="grid1"></ax-datagrid>
mount 函数返回 update
和 destroy
方法。
const { update } = mount('#my-grid', { columns, rows });
//...
update({ rows: newRows });
Data properties
您必须提供 列 和 rows 属性到数据网格以显示一些数据。 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;
mount('ax-datagrid', { columns, 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 }){
alert(`row ${ row.key } clicked!`);
}
mount('ax-datagrid', { onMouse, columns, rows }); // put event handlers together with props

More info
ActiveWidgets/JS • Datagrid
ActiveWidgets is a multi-framework UI component library. This package provides datagrid component for javascript / no-framework environments.
Live demo / Developer guide / API reference
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 });

CDN links
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 });
Live example | Source on github | Edit on Codesandbox
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
