我正在使用如下的jquery文件上传。
dialogElem.find('#upload-image-file-input').fileupload({
url: url,
dataType: 'json',
autoUpload: true,
acceptFileTypes: /(\.|\/)(gif|jpe?g|png)$/i,
maxFileSize: 5000000, // 5 MB
// Enable image resizing, except for Android and Opera,
// which actually support image resizing, but fail to
// send Blob objects via XHR requests:
disableImageResize: /Android(?!.*Chrome)|Opera/
.test(window.navigator.userAgent),
previewMaxWidth: 100,
previewMaxHeight: 100,
previewCrop: true
}).on('fileuploadadd', function (e, data) {
var fileCount = data.originalFiles.length;
if (fileCount > 5) {
alert("The max number of files is : "+5);
return false;
}
}).on('fileuploadprocessalways', function (e, data) {
//some logic
}).on('fileuploadprogress', function (e, data) {
//some logic
}).on('fileuploaddone', function (e, data) {
//some logic
}).on('fileuploadfail', function (e, data) {
//some logic
})
在fileuploadadd
内,我添加了一些验证逻辑。如果验证失败,我该如何停止所有其他活动,例如fileuploadprogress
,fileuploadfail
和fileuploadprocessalways
?

如果你有一些像我几周前那样的任务 - 试试这个:
您可以通过中止XHR(ajax请求)调用来取消正在进行的上传。 您可以绑定到文件输入字段的fileuploadadd事件,在保留jqXHR对象的同时提交请求并将其用于中止:
jqXHR.abort();
例如:
$(".cloudinary-fileupload").bind('fileuploadadd', function(e, data) {
jqXHR = data.submit(); // Catching the upload process of every file
});
$('#cancel_button').click(function (e) {
if (jqXHR) {
jqXHR.abort();
jqXHR = null;
console.log("Canceled");
}
return false;
});
以下页面包含更多代码示例 https://github.com/blueimp/jQuery-File-Upload/issues/290
只需致电
if (fileCount > 5) {
jqXHR.abort();
jqXHR = null; }

jqXHR.abort()对我不起作用。但抛出中止"添加"处理:
.bind('fileuploadadd', function (e, data) {
if (total_uploads >= maxImagesPerPost){
throw new Error('Upload maximum reached');
}
