Get number of files dropped in html5 file upload - javascript

i am a newbie with jquery and i was playing with this plugin. i am using it with asp.net and I want to get number of file dropped in it. I tried a bit but failed to get. Any idea?
Here is the code of script.js:
$(function () {
var dropbox = $('#dropbox'),
message = $('.message', dropbox);
dropbox.filedrop({
paramname: 'pic',
maxfiles: 100,
maxfilesize: 100,
//url: '/Uploader.asmx/Upload',
url: '/Default.aspx',
uploadFinished: function (i, file, response) {
$.data(file).addClass('done');
var count = file.size;
alert(count);
},
error: function (err, file) {
switch (err) {
case 'BrowserNotSupported':
showMessage('Your browser does not support HTML5 file uploads!');
break;
case 'TooManyFiles':
alert('Too many files! Please select 5 at most! (configurable)');
break;
case 'FileTooLarge':
alert(file.name + ' is too large! Please upload files up to 2mb (configurable).');
break;
default:
break;
}
},
//Called before each upload is started
// beforeEach: function (file) {
//if (!file.type.match(/^image\//)) {
//alert('Only images are allowed!');
// alert(file.name);
// Returning false will cause the
// file to be rejected
// return true;
// }
//},
uploadStarted: function (i, file, len) {
createImage(file);
},
progressUpdated: function (i, file, progress) {
$.data(file).find('.progress').width(progress);
}
});
var template = '<div class="preview">' +
'<span class="imageHolder">' +
'<img style="" />' +
'<p class="background: rgba(0, 0, 0, 0.75);"></p>' +
'<span class="uploaded"></span>' + // background: rgba(0, 0, 0, 0.75);
'</span>' +
'<div class="progressHolder">' +
'<div class="progress"></div>' +
'</div>' +
'</div>';
function createImage(file) {
var preview = $(template),
image = $('img', preview),
paragraph = $('p', preview);
var reader = new FileReader();
image.width = 100;
image.height = 100;
reader.onload = function (e) {
// e.target.result holds the DataURL which
// can be used as a source of the image:
//alert(e.target.result);
// $('p#filename').removeAttr('id');
// $('p').attr('id', 'filename' + num + '');
// $('p#filename').text(file.name);
paragraph.attr('id', 'filename').text(file.name);
image.attr('src', '../assets/img/fileicon.png');
num = num + 1;
};
// Reading the file as a DataURL. When finished,
// this will trigger the onload function above:
reader.readAsDataURL(file);
message.hide();
preview.appendTo(dropbox);
// Associating a preview container
// with the file, using jQuery's $.data():
$.data(file, preview);
}
function showMessage(msg) {
message.html(msg);
}
});

It's in the input element. I had a fiddle that uses it in a change event, in which case it's in event.target.files.
edit: should include the fiddle: http://jsfiddle.net/jorgthuijls/uh95y/3/ try it by attaching PDF's.
The relevant code here. This loops over the files and creates "preview" boxes for PDF's but you can just count it as well. files below is an array.
var filesInput = document.getElementById("files");
filesInput.addEventListener("change", function (event) {
var files = event.target.files; //FileList object
var output = document.getElementById("result");
for (var i = 0; i < files.length; i++) {
var file = files[i];
var reader = new FileReader();
reader.addEventListener("load", function (event) {
//stick some rubbish here to check the type of
//file loaded and adjust "type" below. See the
// 'reader' object, it has all that.
var div = document.createElement("div");
div.innerHTML
= '<object data="'
+ reader.result
+ '" type="application/pdf">'
+ '<embed src="'
+ reader.result
+ '" type="application/pdf" />'
+ '</object>';
output.insertBefore(div, null);
});
//Read the image
reader.readAsDataURL(file);
}
});

upload progress bar is jumpy

I've been working on an upload progress bar. The problem is, I can't seem to clean up the motion. It's jumpy, and I think it comes down to not understanding the finer details up the the upload process. What can I do to make this motion smoother?
This script has two movements, progressBarDisp is the target for the upload itself. Then it has a second bar for ajax upon files being processed and receiving a confirmation from the server.
My jumpy item is the progressBarDisp - I can't figure out why it's so jumpy.
$('input[type=file].dicomUpload').on("change", function() {
var files = $(this)[0].files;
//console.log(files);
var theCase = $(this).parent().find('input[name="theCase"]');
var casenum = $(this).parent().find('input[name="casenum"]');
var phase = $(this).parent().find('input[name="phase"]');
var vidnum = $(this).parent().find('input[name="vidNum"]');
processUpload(theCase, casenum, phase, files, vidnum);
});
function processUpload(theCase, casenum, phase, myfiles, vidnum) {
//console.log("Processing: "+vidnum.val());
var progressBox = $('#uploadDicomBox' + casenum.val() + '-' + vidnum.val()).find(".uploadprogress");
progressBox.slideDown();
var progressBarDisp = progressBox.find(".progressBarDisp");
var progressBarComp = progressBox.find(".progressBarComp");
var progressBarText = progressBox.find(".progressText");
progressBarText.text('Processing Upload.');
//run this in two parts - get the file sizes of the acceptable file types
var nBytes = 0;
var uploadedBytes = 0;
var completeBytes = 0;
var tempList = new Array();
$.each(myfiles, function(i, file) {
//console.log(file.name+" -- "+file.name.indexOf("."));
// do any file checking logic here
tempList.push(file);
});
myfiles = tempList;
$.each(myfiles, function(i, file) {
nBytes += file.size;
});
console.log("beginning uploads: " + theCase.val() + ", " + casenum.val() + ", " + phase.val() + ", " + nBytes + ", " + vidnum.val());
//console.log(myfiles);
if (myfiles.length < 1) {
progressBarText.text('No valid file types selected.');
}
//tracking variable
var maxup = 0;
$.each(myfiles, function(i, file) {
//file sizes are going to be an issue for me, these need to be individual file uploads
progressBarText.text('Upload Progress');
// Create a FormData object
var formData = new FormData();
formData.append('casenum', casenum.val());

Have to wait for the second file upload request for the first one's data to send to AWS S3

Any help is greatly appreciated! I've spent so long searching but I haven't found a solution or a problem like mine...
I'm writing an Electron application, and as part of it, there is a section for the users to drag and drop files. I'm then taking that file and uploading it to AWS S3.
The first time I drag and drop it goes into my function but no request is sent out to AWS S3, I then drag and drop again and it sends out the expected request and saves the file however it's the first requests information (name, path & body), and from then on when I drag and drop the file it send outs the request every time but always with the previous request's info. It's like its one sequence behind....
This is the s3 code:
function submitNewFileS3(file, filepath) {
const AWS = require('aws-sdk');
AWS.config = new AWS.Config({
accessKeyId: localStorage.getItem("accessKeyId"),
secretAccessKey: localStorage.getItem("secretAccessKey"),
region: 'eu-west-2'
});
var upload = new AWS.S3.ManagedUpload({
params: {
Bucket: 'sampe-bucket',
Key: filepath, // File name you want to save as in S3
Body: file
}
});
return upload.promise();
}
How I call the function:
var reader = new FileReader();
reader.onload = function (e2) {
// finished reading file data.
finishUploading(e2.target.result);
}
function finishUploading(url) {
// strip off the data: url prefix to get just the base64-encoded bytes
var data;
if (url.indexOf('data:image') > -1) {
data = url.replace(/^data:image\/\w+;base64,/, "");
} else if (url.indexOf('data:application') > -1) {
data = url.replace(/^data:application\/\w+;base64,/, "");
}
//only firing after sencon upload
var buf = Buffer.from(data, 'base64');
var filePathS3 = directory + (fileName).replace(/\-/g, "_").replace(/ /g, "_");
submitNewFileS3(buf, filePathS3).then(function (response) {
console.log(response);
}).catch(function (response) {
console.log(response);
});
}
reader.readAsDataURL(f); // start reading the file data.
Does anyone have any suggestions - I'm going out of my mind...I've tried so many tutorials and solutions and they all work...on the second call...
I've double checked all the required data is ready before making the request.
Many thanks in advance!
EDIT - more of what's going on in my main before sending my file to be uploaded:

}
As an FYI - the issue lied where I reinitialised AWS and S3 variables, it wasn't needed as I set it at the start of launch and reinitialising it slowed it all down while it remade the connection!

Show file name with css and javascript

I have just javascript and css. But want to show the uploaded file name
Googled a lot
So I have this as css:
.metadata .filename{
font-size: 10px;
color: red;
display: inline-block;
}
and this is the js code:
var messagetext = '';
messagetext += '<span class="metadata">' + '<span class="filename">' + file.name + '</span>';
But if I do a console.log(file.name) then I see the name of the uploaded file in the console.
But I dont see it in the view.
Thank you
this is the whole function:
$('body').on('change', '#upload-input', function () {
var halloText = 'file';
var files = $(this).get(0).files;
if (files.length > 0) {
// create a FormData object which will be sent as the data payload in the
// AJAX request
var formData = new FormData();
// loop through all the selected files and add them to the formData object
for (var i = 0; i < files.length; i++) {
var file = files[i];
var message = buildMessage(myUserId, new Date().toISOString(), '<div class="imagepreview"><canvas id="progress' + imagecounter + '" width="80" height="80"></canvas><img id="image' + imagecounter + '"/></div>', 'sent');
message.classList.add('imagesender');
message.classList.add('imagesender' + imagecounter);
conversation.appendChild(message);
//processImages();
conversation.scrollTop = conversation.scrollHeight;
var myCanvas = document.getElementById('progress' + imagecounter);
var circle = new ProgressCircle({
canvas: myCanvas,
});
var percentComplete = 0.65;
circle.addEntry({
minRadius: 30,
fillColor: 'rgba(0, 0, 0, 0.5)',
progressListener: function () {
return percentComplete; // between 0 and 1
}
});
circle.start(33);
var extn = file.name.substring(file.name.lastIndexOf('.') + 1).toLowerCase();
if (extn == "gif" || extn == "png" || extn == "jpg" || extn == "jpeg") {
if (typeof (FileReader) != "undefined") {
var reader = new FileReader();
reader.id = imagecounter;
reader.onload = function (e) {
var imageid = imagecounter;
document.getElementById("image" + e.currentTarget.id).src = e.target.result;
};
reader.readAsDataURL(file);
} else {
// No filereader support... so no preview
}
}
imagecounter++;
// add the files to formData object for the data payload
formData.append('uploads[]', file, file.name);
}
formData.append('Token', SessionInfo.ImageToken);
formData.append('RoomId', currentRoom.RoomId);
dbgMessage(formData);
$.ajax({
url: apipath + '/devices/UploadData',
type: 'POST',
data: formData,
processData: false,
contentType: false,
done: function (data) {
},
error: function(jqXHR, textStatus, errorThrown ){
//show error as a message
var message = buildMessage(myUserId, new Date().toISOString(), jqXHR.responseText, 'error');
conversation.appendChild(message);
conversation.scrollTop = conversation.scrollHeight;
},
xhr: function () {
// create an XMLHttpRequest
var xhr = new XMLHttpRequest();
// listen to the 'progress' event
xhr.upload.addEventListener('progress', function (evt) {
if (evt.lengthComputable) {
// calculate the percentage of upload completed
percentComplete = evt.loaded / evt.total;
if (percentComplete == 1) {
var messagetext = '';
messagetext += '<span class="metadata">' + '<span class="filename">' + file.name + '</span>';
// Handle complete
$('.imagesender').hide();
dbgMessage('Upload complete ');
console.log(file.name);
}
}
}, false);
return xhr;
}
});
}
});
So that the file name will be visible in the html view.
if I do this:
$('.messagewrapper').append('<span class="metadata">' + '<span class="filename">' + file.name + '</span>');
Then it works only after I upload file.
But When I refresh the page the image file is not visible anymore
Like this:
if (percentComplete == 1) {
// Handle complete
$('.imagesender').hide();
dbgMessage('Upload complete ');
}
$('.messagewrapper').append("<p>"+ file.name+"</p>")
append based on id like this should work:
$('#messagewrapper').append("<p>"+ file.name+"</p>")
You will append this only when the file is uploaded because it is inside the if statement:
percentComplete = evt.loaded / evt.total;
if (percentComplete == 1){ //==1 means uploaded
//your append is here
So move it outside the if statement.

How to remove image from selected list use javascript?

I have a html form which is used for uploading file. I can preview images and have delete option from preview itself. However, it isn't deleted from image list which used for uploading the image into server. Please help me to delete the selected image from list
Javascript code:
$(document).ready(function() {
if (window.File && window.FileList && window.FileReader) {
$("#files").on("change", function(e) {
var files = e.target.files,
filesLength = files.length;
for (var i = 0; i < filesLength; i++) {
var f = files[i]
var fileReader = new FileReader();
fileReader.onload = (function(e) {
var file = e.target;
$("<span class=\"pip\">" +
"<img class=\"imageThumb\" src=\"" +
e.target.result + "\" title=\"" + file.name + "\"/>" +
"<br/><span class=\"remove\">Remove image</span>" +
"</span>").insertAfter("#files");
$(".remove").click(function(){
$(this).parent(".pip").remove();
});
});
fileReader.readAsDataURL(f);
}
});
} else{
alert("Your browser doesn't support to File API")
}
});
Change the remove action to this, this will remove all the files
$(".remove").click(function(){
$(this).parent(".pip").remove()
$("#files").val('') // this is new
})
you can't remove only one file as e.target.files is read-only.

Count input files in for loop

I'm using a multiple file input and then a for loop to iterate through the files using FileReader. JSfiddle here: https://jsfiddle.net/zLq8rsos/. It shows filename en contents correctly, but I don't understand why the counting doesn't work. If I choose one file, it's numbered '1' (why not 0?). If I choose two files, they're both counted '2'. What am I doing wrong?
function showDetails(file, content, n) {
var start = content.substring(0, 9);
var message = "File " + n + " is " + file.name + " and starts with " + start + " .<br>";
$('#results').append(message);
}
$(document).ready(function() {
$('#files').on('change', function(evt) {
var files = evt.target.files;
if (files) {
$('#results').text("");
for (var i = 0, f; f = files[i]; i++) {
var reader = new FileReader();
reader.onload = (function(theFile) {
return function(e) {
var content = e.target.result;
showDetails(theFile, content, i);
};
})(f);
reader.readAsText(f, "UTF-8");
}
} else {
console.log("Failed to load file(s)");
};
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="file" id="files" name="files[]" multiple>
<div id="results">
</div>
Use closures Modify IIFE
function showDetails(file, content, n) {
var start = content.substring(0, 9);
var message = "File " + n + " is " + file.name + " and starts with " + start + " .<br>";
$('#results').append(message);
}
$(document).ready(function() {
$('#files').on('change', function(evt) {
var files = evt.target.files;
if (files) {
$('#results').text("");
for (var i = 0, f; f = files[i]; i++) {
var reader = new FileReader();
reader.onload = (function(theFile,count) {
return function(e) {
var content = e.target.result;
showDetails(theFile, content, count);
};
})(f,i+1);
reader.readAsText(f, "UTF-8");
}
} else {
console.log("Failed to load file(s)");
};
});
});
Problem Statement - In for loop when you are trying to access the value of i, it has already completed the iterations and hence the value because 1 for 1 file and 2 for 2 files.
You can update your for loop to
for (var i = 0, f; f = files[i]; i++) {
(function(i){ // Added
var reader = new FileReader();
reader.onload = (function(theFile) {
return function(e) {
var content = e.target.result;
showDetails(theFile, content, i);
};
})(f);
reader.readAsText(f, "UTF-8");
})(i+1);
}
For reference - https://jsfiddle.net/zLq8rsos/1/
JSFIDDLE
All you need is to update the count through loop each time
function showDetails(file, content, n) {
var start = content.substring(0, 9);
var message = "File " + n + " is " + file.name + " and starts with " + start + " .<br>";
$('#results').append(message);
}
$(document).ready(function() {
$('#files').on('change', function(evt) {
var files = evt.target.files;
if (files) {
$('#results').text("");
for (var i = 0, f; f = files[i]; i++) {
var reader = new FileReader();
var x=1;
reader.onload = (function(theFile) {
return function(e) {
var content = e.target.result;
showDetails(theFile, content, x);
x++;
};
})(f);
reader.readAsText(f, "UTF-8");
}
} else {
console.log("Failed to load file(s)");
};
