回答1:

You are actually looking for maxNumberOfFiles option.

More details on the doc: https://github.com/blueimp/jQuery-File-Upload/wiki/Options

My working code:

$('#fileupload').fileupload({         // Uncomment the following to send cross-domain cookies:         //xhrFields: {withCredentials: true},         url: '../uploaderDemo/server/php/',         maxNumberOfFiles: 1,         acceptFileTypes: /(\.|\/)(mp3|wav)$/i     });

Get rid of the object with the name "option" and put the two settings at the same level as the rest of the options.

 $(function() {                     $('#attachUpload').fileupload({                             dataType: 'json',                 limitConcurrentUploads: 1,                 maxFileSize: 40000,                 maxNumberOfFiles: 2,                 start: function(e) {                     $('.btn-sent').unbind('click'); // important - remove all event handlers                 },                 done: function(e, data) {                     var data = $.parseJSON(data._response.jqXHR.responseText);                     doneflag--;                     if (doneflag == 0) {                                                                           $('#frmCompose').submit();                                            }                 },                 submit: function(e, data) {                                     data.formData = setFormData();                                 },                 add: function(e, data) {                 }     });
