Question

导出为csv文件时，文件已下载，但名称为下载且没有扩展名，我尝试过搜索解决方案，但没有得到任何解决方案。

下面是代码。如果我重命名文件并保存为csv，则显示正确的数据

            _addPrintButton: function() {
                var me = this;
                this.down('#print_button_box').add( { 
                    xtype: 'rallybutton', 
                    itemId: 'print_button',
                    text: 'Export to Excel',
                    disabled: false,
                    margin: '20 10 10 0',
                    region: "right",                        
                    handler: function() {
                        me._onClickExport();
                    }

            },

你在错误的地方搜索 Web服务器必须添加HTTP标头Content-Disposition以指示推荐的文件名，例如

Content-Disposition: attachment; filename="correct_data.csv"

导出为csv文件时，文件正在下载但名称下载且没有扩展名
