Question

我正在使用PHPExcel创建Excel工作表，但我遇到了Ajax问题。在Ajax中，当Ajax成功时，我无法生成工作表。在我目前没有Ajax植入表的代码中生成并且每次都要求保存为选项窗口。

没有Ajax的代码（工作）：

/** Error reporting */
error_reporting(E_ALL);
ini_set('display_errors', TRUE);
ini_set('display_startup_errors', TRUE);
date_default_timezone_set('Europe/London');

define('EOL',(PHP_SAPI == 'cli') ? PHP_EOL : '<br />');

/** Include PHPExcel */
require_once dirname(__FILE__) . '/../Classes/PHPExcel.php';

// Create new PHPExcel object
$objPHPExcel = new PHPExcel();

// Create new PHPExcel object
$objPHPExcel = new PHPExcel();

// Create a first sheet, representing sales data
$objPHPExcel->setActiveSheetIndex(0);
$objPHPExcel->getActiveSheet()->setCellValue('A1', 'Something');

// Rename sheet
$objPHPExcel->getActiveSheet()->setTitle('Name of Sheet 1');

// Create a new worksheet, after the default sheet
$objPHPExcel->createSheet();

// Add some data to the second sheet, resembling some different data types
$objPHPExcel->setActiveSheetIndex(1);
$objPHPExcel->getActiveSheet()->setCellValue('A1', 'More data');

// Rename 2nd sheet
$objPHPExcel->getActiveSheet()->setTitle('Second sheet');

// Set active sheet index to the first sheet, so Excel opens this as the first sheet
$objPHPExcel->setActiveSheetIndex(0);


header('Content-Type: application/vnd.ms-excel');
header('Content-Disposition: attachment;filename="name_of_file_'.date('Y/m/d H:i:s').'.xlsx"');
header('Cache-Control: max-age=0');
$objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
$objWriter->save('php://output');

Ajax代码（不工作）：

HTML：

<a href="javascript:void(0);" id="create">Create</a>

jQuery Ajax：

<script type="text/javascript">
    $('#create').click(function() {

        $.ajax({
            type: "POST",
            url: "http://localhost/testing/PHPExcel_1.8.0_doc/Examples/create.php",
            data: "",
            success: function (html) {

            }
        });     

    });
</script>

Create.php

<?php
    /** Error reporting */
    error_reporting(E_ALL);
    ini_set('display_errors', TRUE);
    ini_set('display_startup_errors', TRUE);

    define('EOL',(PHP_SAPI == 'cli') ? PHP_EOL : '<br />');

    /** Include PHPExcel */
    require_once dirname(__FILE__) . '/../Classes/PHPExcel.php';

    // Create new PHPExcel object
    $objPHPExcel = new PHPExcel();

    // Create a first sheet, representing sales data
    $objPHPExcel->setActiveSheetIndex(0);
    $objPHPExcel->getActiveSheet()->setCellValue('A1', 'Something');

    // Rename sheet
    $objPHPExcel->getActiveSheet()->setTitle('Name of Sheet 1');

    // Create a new worksheet, after the default sheet
    $objPHPExcel->createSheet();

    // Add some data to the second sheet, resembling some different data types
    $objPHPExcel->setActiveSheetIndex(1);
    $objPHPExcel->getActiveSheet()->setCellValue('A1', 'More data');

    // Rename 2nd sheet
    $objPHPExcel->getActiveSheet()->setTitle('Second sheet');

    // Redirect output to a client’s web browser (Excel5)
    header('Content-Type: application/vnd.ms-excel');
    header('Content-Disposition: attachment;filename="name_of_file_'.date('Y/m/d H:i:s').'.xlsx"');
    header('Cache-Control: max-age=0');
    $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel5');
    $objWriter->save('php://output');
?>

任何想法？为什么工作表没有生成以及为什么保存为窗口没有打开。

感谢。

Answer 1

如果您使用ajax生成文件，则需要执行以下步骤：

向server / PHP发送请求以生成文件。保存该文件＆amp;发送文件名作为回应。
在成功回调中接收文件名后，将浏览器重定向到任何显示实际生成文件（带标题）的php文件，即。 window.location.href='downloadFile.php?filename=abcd.pdf'

Answer 2

试试这个：

<script type="text/javascript">
    $('#create').click(function() {

        $.ajax({
            url: "",
            beforeSend: function() {
            location.href = "http://localhost/testing/PHPExcel_1.8.0_doc/Examples/create.php";
            },
            success: function (html) {

            }
        });     

    });
</script>

试试这个：

PHP代码 - ＆gt;返回数组

        header('Content-Type: application/vnd.ms-excel'); 
        header('Content-Disposition: attachment;filename="'.$filename.'"'); 
        header('Cache-Control: max-age=0'); 


        $objWriter = PHPExcel_IOFactory::createWriter($objPHPExcel, 'Excel2007');  

        $objWriter = new PHPExcel_Writer_Excel5($objPHPExcel);

        $objWriter->save("php://output");
        $xlsData = ob_get_contents();
        ob_end_clean();

        $objPHPExcel->disconnectWorksheets();
        unset($objPHPExcel);


        $response =  array(
            'status' => true,
            'file' => "data:application/vnd.ms-excel;base64,".base64_encode($xlsData),
            'log' => $log_mensaje
        );

JQUERY CODE
