请给我代码示例以覆盖任何 uploadifive 方法。
在这里我放了我的js代码，请看一下。我想从后端检查重复文件。我已经在控制器中有方法。
如果您提供任何关于如何覆盖方法的示例，那么我可以尝试。
$('#file_upload').uploadifive({
'auto' : true,
'buttonText' : 'Select File',
'checkScript' : false,
'queueSizeLimit' : 10,
'fileSizeLimit' : 10737418240,
'dnd' : false,
'multi' : true,
'removeCompleted' : true,
'queueID' : 'queue',
'simUploadLimit' : 30,
'uploadLimit' : 30,
'overrideEvents' : ['onProgress'],
'uploadScript' : '/files/pending',
// Triggered for each file that is added to the queue
'onAddQueueItem' : function(file) {
console.log(file.name + "file that is added to the queue");
var folder = files.currentItemData();
this.data('uploadifive').settings.formData = {
'timestamp' : current_date_time(),
'authenticity_token' : token(),
'attachment[folder_id]' : folder.id,
'attachment[context_code]' : current_context_code(),
'attachment[language]' : uploadifive_language_code(),
'success_action_status' : "201",
//'attachment[duplicate_handling]': file.duplicate_handling,
};
},
// Triggered when a file is cancelled or removed from the queue
'onCancel' : function() {},
// Triggered when the server is checked for an existing file
'onCheck' : function() {},
// Triggered during the clearQueue function
'onClearQueue' : function() {},
// Triggered when files are dropped into the file queue
'onDrop' : function() {},
// Triggered when an error occurs
'onError' : function(file, fileType, data) {},
// Triggered if the HTML5 File API is not supported by the browser
'onFallback' : function() {},
// Triggered when UploadiFive if initialized
'onInit' : function() {},
// Triggered once when an upload queue is done
'onQueueComplete' : function(file, data) {},
// Triggered during each progress update of an upload
'onProgress' : function(file, e) {
if (e.lengthComputable) {
var percent = Math.round((e.loaded / e.total) * 100);
}
$('.uploadifive-queue-item').find('.fileinfo').html(' - ' + percent + '%');
$('.uploadifive-queue-item').find('.progress-bar').css('width', percent + '%');
},
// Triggered once when files are selected from a dialog box
'onSelect' : function(file) {
console.log(file.queued + ' files were added to the queue.');
return;
},
// Triggered when an upload queue is started
'onUpload' : function(file) {
console.log(file + ' files will be uploaded.');
file_select_done();
},
// Triggered when a file is successfully uploaded
'onUploadComplete' : function(file, data) {
res_data = JSON.parse(data);
$.ajaxJSON(res_data.success_url,'GET',{"authenticity_token" : authenticity_token},function(data) {
if (data && data["attachment"]){
var file_id = data["attachment"]["id"];
var file_name = data["attachment"]["display_name"];
generate_li(file_name, file_id);
qutaUpdate();
}
});
console.log('The file ' + file.name + ' uploaded successfully.');
},
// Triggered for each file being uploaded
'onUploadFile' : function(file) {
console.log('The file ' + file.name + ' is being uploaded.');
}
});});
