如何创建一个公共服务以将 jQuery 数据表集成到 angular 中的所有页面 [英] How to create a common service to integrate jQuery datatable for all pages in angular

问题描述

我想创建公共服务以在多个页面上集成 jQuery 数据表(带有导出按钮).

我已经安装了 jquery 和 jquery 类型.还在 tsconfig types 数组中包含了 jquery.

类型":[jQuery"]

在索引页上包含数据表所需的 CDN.

在typings.d.ts中添加了一个JQuery接口:

interface JQuery {<dataTable>(options?: any): any;}

角度服务:

 ApplyDatatable() {$(".mydataTable").dataTable({"pagingType": "full_numbers","iDisplayLength": 10,bJQueryUI:真，"aLengthMenu": [[-1, 10, 20, 50, 100], ["All", 10, 20, 50, 100]],选择:真，"asorting": [],aoColumnDefs":[{'bSortable':假，'aTargets': ['disableSorting', 'noExport']}],纽扣: [{扩展:'集合'，文本:'出口'，纽扣: [//'复制'，{扩展:'copyHtml5'，出口选项:{列:':可见'，列:thead th:not(.noExport)"}},{扩展:'csvHtml5'，出口选项:{列:':可见'，列:thead th:not(.noExport)"}}],dom: 'lfBrtip',});}

出现错误:

jquery__WEBPACK_IMPORTED_MODULE_6__(...).dataTable 不是函数(在浏览器控制台上).

编译项目时出现错误属性 'dataTable' 在类型 'JQuery' 上不存在

解决方案

当使用 jQuery 插件时，您应该创建一个 Angular 组件作为数据表的包装器.然后就可以在组件渲染后调用jQuery插件了.

import { Component, AfterViewInit } from '@angular/core';导入'jquery';@成分({选择器:'应用程序数据表'，...})导出类 AppDatatables 实现 AfterViewInit {ngAfterViewInit() {($(".mydataTable") as any).dataTable({...});}}

组件模板:

因为您已经在另一个问题 如何为每个新页面(视图)呈现这个，这个问题现在也解决了，因为每次加载/创建新页面时都会重新添加组件.

I want to create common service to integrate jQuery datatables(with export buttons) on multiple pages.

I have installed jquery and typings for jquery. Also have included jquery in tsconfig types array.

"types": [
  "jquery"
]

Included required cdn(s) for datatable on index page.

Added an interface JQuery in typings.d.ts :

interface JQuery {
  <dataTable>(options?: any): any;
}

Angular Service :

  ApplyDatatable() {
          $(".mydataTable").dataTable({
                "pagingType": "full_numbers",
                "iDisplayLength": 10,
                bJQueryUI: true,
                "aLengthMenu": [[-1, 10, 20, 50, 100], ["All", 10, 20, 50, 100]],
                select: true,
                "aaSorting": [],
                "aoColumnDefs": [
                  {
                    'bSortable': false,
                    'aTargets': ['disableSorting', 'noExport']
                  }],
                buttons: [
                  {
                    extend: 'collection',
                    text: 'Export',
                    buttons: [
                      //'copy',
                      {
                        extend: 'copyHtml5',
                        exportOptions: {
                          columns: ':visible',
                          columns: "thead th:not(.noExport)"
                        }
                      },
                      {
                        extend: 'csvHtml5',
                        exportOptions: {
                          columns: ':visible',
                          columns: "thead th:not(.noExport)"
                        }
                      }                
                ],         
                dom: 'lfBrtip',    
              }); 
}

Getting error :

jquery__WEBPACK_IMPORTED_MODULE_6__(...).dataTable is not a function (on browser console).

while compiling project getting the error Property 'dataTable' does not exist on type 'JQuery'

解决方案

When using a jQuery plugin, you should create an Angular component as a wrapper for the datatable. Then you can call the jQuery plugin after the component renders.

import { Component, AfterViewInit } from '@angular/core';
import 'jquery';

@Component({
  selector: 'app-datatables',
  ...
})
export class AppDatatables implements AfterViewInit {
  ngAfterViewInit() {
    ($(".mydataTable") as any).dataTable({
      ...
    });
  }
}

Component template:

<div class="mydataTable"></div>

---

Since you already asked in another question how to render this for every new page(view), that problem is solved now as well, since the component will be re-added every time a new page is loaded/created.
