我没有构建我们网站的这一部分，但因为其他开发人员已被拉入另一个项目，这是我的工作来解决这个问题。基本上我们使用基本的蓝色imp文件上传插件通过ajax提交文件。当我第一次挑选文件并上传时，一切正常。当我选择一个新文件并上传时，它会提交两次。第一个文件和第二个文件。如果之后我选择了一个新文件，它会提交3次，等等。如果我放弃文件而不是上传文件，会发生同样的情况。我不能，因为我一生都在想什么触发它多次运行，并且我在线上没有任何帮助。Blueimp File Uploader多次提交

这里是JS

function uploadThis(){
var $form = $('input[type=file]').closest('form'),
userid = $form.data('user'),
url = $form.attr('action'),
uploadButton = $form.find('.new-doc span');
$('input[type=file]').fileupload({
url: url,
multipart: true,
singleFileUploads: true,
add: function (e, data) {
data.context = $form.find('.newdoc').click(function() {
console.log($(this));
data.submit();
return false;
});
},
change: function (e, data){
if($(this).attr('id') === "image-input"){}
else{
var thisform = $(this).closest('form');
$.each(data.files, function(index,file){
data.context = thisform.find('.upload-button span').text('Selected file: ' + file.name);
});
}
},
done: function (e, data) {
var thisform = $(this).closest('form');
data.context = thisform.find(".upload-button input").find(".files").empty();
$(this).wrap('<form>').closest('form').get(0).reset();
$(this).unwrap();
},
stop: function(e, data) {
},
failed: function (e, data) {
data.context.text('Unable to upload document.');
}
});
}
// document uploads
$('.document-upload').each(function(){
var userid = $(this).data('user');
//some code retracted to keep it simpler
uploadThis();
});
// end document uploads
// discard doc
$('#add-new-doc .discarddoc').on('click', function(e){
e.preventDefault();
var $this = $(this),
$form = $(this).closest('form');
$form[0].reset();
$form

对不起，我试图修复它尽可能的格式。任何见解都会很棒。谢谢
