Codeigniter PHPExcel通过ajax调用下载

Question

我在通过ajax将数据从view发送到我的phpexcel函数时遇到问题。我尝试了以下解决方案＆＃34; PHPExcel download using ajax call＆＃34;但似乎我仍然缺少一些东西。我添加一个控制台日志，以查看数据是否已传输，是否有，但它只打印标题而不是数据库中的内容。请帮忙......这是我的ajax的代码：

$('#btnExport').click(function(){
var fdate = $('#dateFrom').val();
var tdate = $('#dateTo').val();
var dept = $('#txtdept').val();
var item1 = $('#txtsearch3').val();
var formData;
var page = "<?php echo site_url('tms/exportToExcel');?>";

//formData = $('#formData1').serialize();

if(fdate == "" || tdate == "")
{
    $('#no-dates').modal('show');
}
else if(fdate == "" && tdate == "")
{
    $('#no-dates').modal('show');
}
else
{

    if(dept != "")
    {
        $.ajax({
            type: 'POST',
            url: page,
            data: {dept:dept,fdate:fdate,tdate:tdate},
            success: function(response){
                console.log(response);
                window.open(page,'_blank');
            },
        });
    }

    else if(item1 != "")
    {
        $.ajax({
            type: 'POST',
            url: "<?php echo site_url('tms/exportsolo')?>",
            data: {item1:item1,fdate:fdate,tdate:tdate},
            success: function(){
                window.open(page,'_blank');
            },
        });
    }
    //console.log(dept+" "+fdate+" "+tdate);
}
//window.open(page);

});

这是创建excel文件的功能之一：

public function exportToExcel()

    $from = @date('Y-m-d',@strtotime($this->input->post('fdate')));

我不知道是否需要修改这个，因为当我不使用ajax时它会100％工作......

Answer 1

不使用ajax但您可以尝试更改＆＃34;操作＆＃34;您的表单属性和使用表单提交。用户不会被重定向，但要求根据从php收到的标题下载文件。

$('#btnExport').click(function(){
var fdate = $('#dateFrom').val();
var tdate = $('#dateTo').val();
var dept = $('#txtdept').val();
var item = $('#txtsearch3').val();
var form = $('#yourFromId');

if(fdate == "" || tdate == "")
{
    $('#no-dates').modal('show');
}
else if(fdate == "" && tdate == "")
{
    $('#no-dates').modal('show');
}
else
{
    if(dept != "" && item == "")
    {
        // update form fields if needed
        form.attr('action', "<?php echo site_url('tms/exportToExcel');?>");
        form.submit();
    }
    else if(dept == "" && item != "")
    {
        // update form fields if needed
        form.attr('action', "<?php echo site_url('tms/exportsolo');?>");
        form.submit();
    }
}
});

Answer 2

我通过调整一点RatHat代码答案解决了我的问题，这就是拯救我的原因：

$('#btnExport').click(function(){
var fdate = $('#dateFrom').val();
var tdate = $('#dateTo').val();
var dept = $('#txtdept').val();
var item = $('#txtsearch3').val();
var form1 = $('#formData1');
var form2 = $('#formData2');

$('#txtdept').val(dept);
$('#txtfdate1').val(fdate);
$('#txtTdate1').val(tdate);

$('#txtItem').val(item);
$('#txtfdate2').val(fdate);
$('#txtTdate2').val(tdate);   



if(fdate == "" || tdate == "")
{
    $('#no-dates').modal('show');
}
else if(fdate == "" && tdate == "")
{
    $('#no-dates').modal('show');
}
else
{
    if(dept != "")
    {
        form1.attr('action',"<?php echo site_url('tms/exportToExcel');?>");
        form1.attr('method','POST');
        form1.submit();
    }
    else if(item != "")
    {
        form2.attr('action',"<?php echo site_url('tms/exportsolo');?>");
        form2.attr('method','POST');
        form2.submit();
    }
}
});
