如何在blueimp Basic中开始上载之前从队列中删除文件以停止上载? [英] How to remove file from the queue to stop upload before upload starts in blueimp Basic?
问题描述
这是东西,
我想要类似于 Basic 中的Basic plus UI或jQuery UI的取消按钮.这个问题对您来说可能看起来很愚蠢.但是实际上我从模板中混淆了blueimp在Basic plus UI或jQuery UI中使用开始,删除和取消按钮列出上传和下载文件的方式.
I want cancel button similar to Basic plus UI or jQuery UI in Basic. This question might look silly to you. But actually i got confuse from template which blueimp are using in Basic plus UI or jQuery UI to list upload and downloaded file with start, delete and cancel button.
在此处即使是我也不能使用该模板,因为我正在使用树枝模板,该模板具有类似的语法,如果使用该模板则会出错.
EDIT 1 here: Even i can't use that template because i am working in twig template, which has similar syntax which give error if i use.
我需要代码才能从队列中删除文件,并防止在开始上传之前进行上传.
I need code to remove file from the queue and to prevent upload before upload start.
我搜索了_cancelHandler在jquery.fileupload-ui.js中,但是有很多功能使我感到困惑.
I searched that _cancelHandler is in jquery.fileupload-ui.js but there are lots of function which are making me confuse.
请有人帮助.
即使我已经阅读了文档中的插件的基本用法(最低设置指南),但没有数据具有取消按钮.
Even i read basic use of plugin in documentation (minimal setup guide) but there is not data to have cancel button.
在此处编辑2 :我想我错过了告诉我只需要一个上传按钮的功能,该按钮将上传队列中的所有文件.如果列表中的任何文件被取消,则不应上传.
EDIT 2 here : I think i missed to tell that i need only single upload button which will upload all the files which are in queue. if any file in the list cancelled then that should not upload.
这是我的代码
$(function () {
var cancel_btn = $('<button/>')
.addClass('btn btn-warning cancel pull-right')
.html('<i class="icon-ban-circle icon-white"></i><span> Cancel')
.on('click', function () {
var $this = $(this),
data = $this.data();
$(this).parents('tr').remove();
alert("code to remove from the queue and to prevent upload before upload start");
});
var delete_btn = $('<button/>')
.addClass('btn btn-danger cancel pull-right')
.html('<i class="icon-ban-circle icon-white"></i><span> Delete')
.on('click', function () {
alert('code needed to delete file');
});
$('#fileupload').fileupload({
dataType: 'json',
autoUpload: false,
add: function (e, data) {
console.log(data);
// data.context = $('<div/>').appendTo('#files');
$.each(data.files, function (index, file) {
var tr = document.createElement('tr');
var td1 = document.createElement('td');
var td2 = document.createElement('td');
var td3 = document.createElement('td');
$(td1).append(file.name);
$(td2).append(file.size);
$(td3).append(cancel_btn.clone(true).data(data));
$(tr).append(td1,td2,td3);
$('#files_list tbody').append(tr);
var size = $('#files_list tbody tr').size();
if(size < 1 )
$('#files_list').addClass('hide');
else
$('#files_list').removeClass('hide');
});
$('#submit').click(function (){
//data.context = $('<p/>').text('Uploading...').replaceAll($(this));
data.submit();
$('#files_list tbody').html('');
});
},
done: function (e, data) {
$.each(data.result.files, function (index, file) {
var tr = document.createElement('tr');
var td1 = document.createElement('td');
var td2 = document.createElement('td');
var td3 = document.createElement('td');
$(td1).append(file.name);
$(td2).append(file.size);
$(td3).append(delete_btn.clone(true).data(data));
$(tr).append(td1,td2,td3);
$('#files_list tbody').append(tr);
});
},
fail: function (e, data) {
//console.log(data.result);
$.each(data.result.files, function (index, file) {
var error = $('<span/>').text(file.error);
$(data.context.children()[index])
.append('<br>')
.append(error);
});
},
progressall: function (e, data) {
var progress = parseInt(data.loaded / data.total * 100, 10);
$('#progress .bar').css(
'width',
progress + '%'
);
}
});
});
推荐答案
您可以向每个文件添加上传"和取消"按钮,并将提交功能绑定到这些按钮上.
You can add an "upload" and "cancel" button to every file and bind the submit function on these buttons.
var cancel_btn = $('<button/>')
.addClass('btn btn-warning cancel pull-right')
.html('<i class="icon-ban-circle icon-white"></i><span> Cancel')
var upload_btn = $('<button/>')
.addClass('btn btn-warning upload pull-right')
.html('<i class="icon-ban-circle icon-white"></i><span> Upload')
});
$('#submit').on('click',function(){
$('.upload').click() //click upload buttons and upload all files in the queue
})
$('#cancel').on('click',function(){
$('.cancel').click() //click cancel buttons and remove all files in the queue
})
.......
$('#files_list tbody').append(tr);
$(td4).append(upload_btn.clone(true).data(data));
$('.upload').eq(-1).on('click',function(){//button to upload only this file
data.submit();
})
$('.cancel').eq(-1).on('click',function(){
$(this).parent().parent().remove()//or something like this,
//delete the whole <tr>
//and remove the file from the queue
})
