如何在Angular 2中使用DataTable [英] How to use DataTable in Angular 2

问题描述

我想在Angular 2应用中使用DataTable。但这不起作用。 Angular 2中没有可能在模板中添加脚本标记。你知道我怎么能这样做吗？我想我必须在systemJs中做一些改变。

I want to use the DataTable in my Angular 2 app. But this is not working. There is no possiblity in Angular 2 to add a script tag in templates. Do you know how can I do this? I think I have to do some changes in the systemJs.

list.html：

list.html:

<table id="example" class="display" cellspacing="0" width="100%">
        <thead>
            <tr>
                <th>Name</th>
                <th>Position</th>
                <th>Office</th>
                <th>Age</th>
                <th>Start date</th>
                <th>Salary</th>
            </tr>
        </thead>
        <tfoot>
            <tr>
                <th>Name</th>
                <th>Position</th>
                <th>Office</th>
                <th>Age</th>
                <th>Start date</th>
                <th>Salary</th>
            </tr>
        </tfoot>
        <tbody>
              <tr>
                <td>Gavin Cortez</td>
                <td>Team Leader</td>
                <td>San Francisco</td>
                <td>22</td>
                <td>2008/10/26</td>
                <td>$235,500</td>
            </tr>
            <tr>
                <td>Martena Mccray</td>
                <td>Post-Sales support</td>
                <td>Edinburgh</td>
                <td>46</td>
                <td>2011/03/09</td>
                <td>$324,050</td>
            </tr>
        </tbody>
    </table>

my Component：

my Component:

...
declare var jQuery:any;
..
ngOnInit():any{
       console.log("Augerufen");
       jQuery('#example').DataTable();
   }
...

在我的index.html中，我添加了必需的库：

In my index.html I have added the required libaries:

<!-- Bootstrap Core CSS -->
    <link href="css/bootstrap.min.css" rel="stylesheet">
    <link href="css/jquery.dataTables.min.css" rel="stylesheet">
<!-- jQuery -->
    <script src="js/jquery.js"></script>
    <script src="js/jquery.dataTables.min.js"></script>
    <!-- Bootstrap Core JavaScript -->
    <script src="js/bootstrap.min.js"></script>

提前致谢！

推荐答案

您可以为DataTable创建一个指令，然后在您的组件上使用该指令。

You can create a Directive for DataTable, then use the directive on your component.

这样：

import {Directive, ElementRef} from '@angular/core';
import {Input, OnInit}         from '@angular/core';


import { JqueryDataTableEvent } from './jquery-datable-event';
import 'jquery.dataTables';

declare var jQuery:any;

@Directive({
    selector: '[jqueryDatatable]'
})

export class JqueryDatatableDirective implements OnInit {
    private _datatable : any;

    @Input()
    jqueryDatatable: any;

    @Input()
    dataTableEvents: JqueryDataTableEvent[];

    constructor(private _element: ElementRef) {}

    ngOnInit() {
        this.applyOptions();
        this.applyEvents();
    }

    applyOptions()
    {
        if (!this.jqueryDatatable)
            console.error("Empty options array was passed to initialize jqueryDatatable.");

        this._datatable = jQuery(this._element.nativeElement).DataTable( this.jqueryDatatable || {} );

    }

    applyEvents() {
        this.dataTableEvents.map((event)=> {
            this._datatable.on(event.eventName, event.selector, event.callback)
        });
    }
}

此示例可以改进，但对于基本功能，好的。

this example could be improved, but for basic features its ok.
