Question

我编写了函数来获取xls的导出链接

 {
  text: 'Download as xls',
  onclick: function() {
  location.href="getXLS.php?param1=param&param2=para2";}
   }

但我不想将GET用作导出，因为它会将我重定向到页面getXLS。我想让它像其他功能一样（例如导出到png，我点击它并出现下载窗口）

我想我应该使用AJAX，但不知道如何使用它......

将数据保存到xls我将使用http://phpexcel.codeplex.com/但首先我需要POST该数据而不将页面重新加载到getXLS。

依靠你们，伙计们！

Answer 1

如果我弄错了，你想强制下载而不是重定向吗？如果是，请将这些标题添加到getXLS.php

的顶部

<?php
  // We'll be outputting an excel file
header('Content-Type: application/vnd.ms-excel;'); // This should work for IE & Opera
header("Content-type: application/x-msexcel");    // This should work for the rest       
// It will be called dataAsExcel.xls
  header('Content-Disposition: attachment; filename="dataAsExcel.xls"');
?>

这将指示您正在发送类型为excel的文件的浏览器，因此浏览器将使用save as对话框提示用户。

有关php @ http://php.net/manual/en/function.header.php

好的，怎么做：

Firtst，make function

function postajax(datas)
{
$.post('PHPExcel/export/ajax.php', datas, function(retData) {
  $("body").append("<iframe src='PHPExcel/export/ajax.php' style='display: none;' ></iframe>");
}); 
}

现在创建下载xls文件的按钮

buttons: {
            exportButton: {
                menuItems: [{},
                {},
                {},
                {}, /* leave standard buttons */
                {
                    text: 'Download as xls',
                    onclick: function() {
                        postajax('My vaariable') 
                    }
                }]
            }
        }

就是这样，现在从http://phpexcel.codeplex.com/下载库而且你做完了！
