blueimp jquery-file-upload如何在上传之前取消1个文件 [英] blueimp jquery-file-upload how to cancel 1 file before upload
问题描述
我正在使用以下库
https://github.com/ blueimp / jQuery-File-Upload / wiki
我选择了(添加文件)按钮后显示选定的文件。我没有显示演示网格显示取消按钮或上传
我有一个按钮,提交(见下文)。
我想要取消选择这个上传按钮之前选择的文件上传。
通过代码,我看到,当我终于击中提交,它调用fileuploadsubmit上传每个文件。
我想向用户显示所选文件的网格,然后通过从数据中删除链接来取消其中的一个。我在网上找到的所有样本倾向于parent()。remove(),从而从可视网格中删除。
我怎样才能不显示网格?
b$ b $ $
add:function(e ,data){
$ .each(data.files,function(index,file){
files + = file.name;
});
$('#files')。text(files);
viewModel.Add(data);
$ b data.context = $('#btnUpload')
.click(function(){
data.submit();
return false;
});
$ b $('#fileupload')。bind('fileuploadsubmit',function(e,data){
//示例输入不一定是上传表单的一部分:
// var input = $('#input');
//data.formData = {example :input.val()};
var countryId = 1; //viewModel.selectedCountry()。CountryId()
var selected ='test'; // $('#lstTemplate ();
$ b data.formData = {templateType:selected,countryId:countryId};
if(data.formData.templateType =='Select'){
data.context.find('button')。prop('disabled',false);
return false;
}
});
实际上可以从data.files中删除一个文件。
我正在使用KnockoutJs Web组件存储上传对象的实例,我有文件列表的可观察数组...
我的配置是:
.fileupload({
url:DataServiceBaseUrl +'/ api / Ruleset / BatchImport',
dataType:'json',
singleFileUploads:false,
replaceFileInput:false,
add:function(e,data){
...
我所做的是
this.RemoveFile = function(index){
this.UploadInstance.files.splice(index,1);
this.UploadFiles.splice(index,1);
}
和模板是:
<! - ko foreach:UploadFiles - >
< div>< span data-bind =text:name>< / span> bind =click:function(){$ component.RemoveFile($ index());}>删除< / button>< / div>
<! - / k o - >
I am using the following library https://github.com/blueimp/jQuery-File-Upload/wiki
I am showing the selected files after (add files) button is selected. I am not showing the demo grid showing cancel button or upload
I have a button which does the submit (see below). I would like to cancel the upload of one of the files selected before this upload button is selected.
Walking through the code i see that when i finally hit submit, it calls fileuploadsubmit for each file uploaded.
I would like to show to the user grid of files selected, then allow them to cancel one of them by picking a link to remove from data. All the samples i am finding online tend to parent().remove() thereby removing from visual grid.
How can i do without showing that grid?
ie..
...
add: function (e, data) {
$.each(data.files, function (index, file) {
files += file.name;
});
$('#files').text(files);
viewModel.Add(data);
data.context = $('#btnUpload')
.click(function () {
data.submit();
return false;
});
},
......
$('#fileupload').bind('fileuploadsubmit', function (e, data) {
// The example input, doesn't have to be part of the upload form:
//var input = $('#input');
//data.formData = {example: input.val()};
var countryId = 1; //viewModel.selectedCountry().CountryId()
var selected = 'test'; //$('#lstTemplate option:selected').text();
data.formData = { templateType: selected, countryId: countryId };
if (data.formData.templateType == 'Select') {
data.context.find('button').prop('disabled', false);
return false;
}
});
Actually is possible to remove one file from data.files. I'm using KnockoutJs web-component in which I'm storing instance of "upload object" and I have observable array for file list ...
My configuration is:
.fileupload({
url: DataServiceBaseUrl + '/api/Ruleset/BatchImport',
dataType: 'json',
singleFileUploads: false,
replaceFileInput: false,
add: function (e, data) {
...
what I did is
this.RemoveFile = function(index){
this.UploadInstance.files.splice(index,1);
this.UploadFiles.splice(index,1);
}
and template was:
<!-- ko foreach: UploadFiles -->
<div><span data-bind="text: name"></span><button data-bind="click: function() { $component.RemoveFile($index()); }">delete</button></div>
<!-- /ko -->
