通过React App的Datatables按钮 [英] Datatables button through React App

问题描述

在React中工作时，尝试添加excel导出按钮时遇到了问题。我认为这与导入有关，但是在这方面，我在网上找不到与React和DataTables.net相关的帮助。我只是希望用户能够下载到excel。

I've been having issues trying to add an excel export button when working in React. I assume it has something to do with an import but I can't find much help online related to React and DataTables.net in this regard. I just want a user to be able to download to excel.

这些是我与jquery和数据表相关的导入

these are my imports related to jquery and datatables

const $ = require('jquery');
$.DataTable = require('datatables.net');
import 'datatables.net-dt/css/jquery.dataTables.css'

此处是定义表的位置。除按钮以外，其他功能均有效。

here is where the table is defined. It works except for the buttons

componentDidMount() {
    this.$el = $(this.el);
    this.$el.DataTable({
          dom: 'Bfrtip',
          data: this.makeArray(),
          columns: this.getColumns(),
          pageLength:this.props.json.length,
          buttons: [
                {
                    extend: 'excel',
                    text: 'Save current page',
                    fileName:  "data.xlsx",
                    exportOptions: {
                       modifier: {
                            page: 'current'
                           }
                    }
                 }]});
}

这是渲染方法

render() {
    return (
        <div>
            <table className="display" width="100%" ref={el=>this.el=el} />
        </div>);
}

不胜感激

推荐答案

回答了我自己的问题

需要安装jzip，需要它，然后将其附加到窗口对象

needed to do install jzip, require it and then attach it to the window object

const jzip = require( 'jzip');
window.JSZip = jzip;

我也将按钮切换为excelhtml5。这是我所有的jquery /数据表导入

I also switched the button to excelhtml5. Here are all the jquery/datatable imports I have

const $ = require('jquery');
$.DataTable = require('datatables.net');
import 'datatables.net-dt/css/jquery.dataTables.css'
require( 'datatables.net-buttons/js/dataTables.buttons.min' );
const jzip = require( 'jzip');
require( 'datatables.net-buttons/js/buttons.html5.min' );
import 'datatables.net-buttons-dt/css/buttons.dataTables.css'

window.JSZip = jzip;

这是componentDidMount方法的更新按钮部分。

here is the updated buttons portion of the componentDidMount method.

componentDidMount() {
    this.$el = $(this.el);
    this.$el.DataTable({
        dom: 'Bfrtip',
            data: this.makeArray(),
            columns: this.getColumns(),
                paging:false,
    buttons: [
        'excelHtml5'
    ]
        }
    );
}
