Dropzone showing the V&X icons below the drop box

My Flask project with Dropzone implementation dont show the file upload progress bar but rather both the 'V' and 'X' icons for each file, like this (the 'v' and 'x' icons are bearly visible below the file name):
, and they appear below the drop box, together with the file name and size, instead of inside the drop box. The files gets uploaded though, but the behaviour is undesired. Has anybody encountered the same problem?
HTML part:
<form id="myProjFileUploadForm" method="post" enctype="multipart/form-data" action="{{ url_for('projects.projects_file_upload') }}">

Invalid argument supplied for foreach() using laravel 7 [duplicate]

I have a lot of problem to upload multiple images using AJAX. I write this code:
HTML
<form id="upload" method="post" enctype="multipart/form-data">
<div id="drop" class="drop-area">
<div class="drop-area-label">

</div>
<input type="file" name="file" id="file" multiple/>
</div>
<ul class="gallery-image-list" id="uploads">
<!-- The file uploads will be shown here -->
</ul>
</form>
<div id="listTable"></div>
jQuery/AJAX
$(document).on("change", "input[name^='file']", function(e){
e.preventDefault();
var This = this,
display = $("#uploads");
// list all file data
$.each(This.files, function(i, obj){
// for each image run script asynchronous
(function(i) {
// get data from input file
var file = This.files[i],
name = file.name,
size = file.size,
type = file.type,
lastModified = file.lastModified,
lastModifiedDate = file.lastModifiedDate,
webkitRelativePath = file.webkitRelativePath,
slice = file.slice,
i = i;
// DEBUG
/*
var acc = []
$.each(file, function(index, value) {

});
alert(JSON.stringify(acc));

$.ajax({

xhr: function() {

// Check if upload property exists
if(myXhr.upload)
{
// For handling the progress of the upload
myXhr.upload.addEventListener("progress",progressHandlingFunction, false);
}
return myXhr;
},
cache: false,
success : function(data){
// load ajax data
$("#listTable").append(data);
}
});
// display progress
function progressHandlingFunction(e){
if(e.lengthComputable){
var perc = Math.round((e.loaded / e.total)*100);
perc = ( (perc >= 100) ? 100 : ( (perc <= 0) ? 0 : 0 ) );
$("#progress"+i+" > div")
.attr({"aria-valuenow":perc})
.css("width", perc+"%");
}
}
// display list of files

})(i);
});
});
I've tried a various versions and I never succeed to send multiple data through ajax. I have tried in this way what you see above, and now I get only POST informations. I understand why i get POST but I need to send FILES information and I do not know where I'm wrong.
I not work the first time with ajax and often use it for most projects but I have never used to send multiple files and that bothering me now.
Thanks!

How to use ajax to post Kendo upload files to controller

When i use ajax to post the form data to controller, i cannot get the files when using Kendo upload. I used IEnumerable but i only can get the date value and the file is null. May i know how to make it work? Thanks.
(I use ajax because i need call the onsuccess event)
//Here is the form control in view
<div class="editForm">
#using (Html.BeginForm("UpdateReportFix", "Defect", FormMethod.Post, new { id = "form" }))
{
#Html.HiddenFor(model => model.DefectFixID)
<div>
#Html.Label("Report Date")
</div>
<div>
#(Html.Kendo().DatePickerFor(model => model.ReportDate)
.Name("ReportDate")
.Value(DateTime.Now).Format("dd/MM/yyyy")
.HtmlAttributes(new { #class = "EditFormField" })
)
#Html.ValidationMessageFor(model => model.ReportDate)
</div>
<div>
#Html.Label("Photos")
<br />
<span class="PhotosMessage">System Allow 2 Pictures</span>
</div>
<div class="k-content">
#(Html.Kendo().Upload()
.Name("files") <-----i cannot get this value in controller
)
</div>
<br />
<div class="col-md-12 tFIx no-padding">
#(Html.Kendo().Button().Name("Cancel").Content("Cancel").SpriteCssClass("k-icon k-i-close"))
#(Html.Kendo().Button().Name("submit").Content("Submit").SpriteCssClass("k-icon k-i-tick"))
</div>
}
//script
$('form').submit(function (e) {
e.preventDefault();
var frm = $('#form');
$.ajax({

type: 'POST',
data: frm.serialize(),
beforeSend: function () {
},
onsuccess: function () { },
success: function (result) { },
error: function () { }

});

Access dropdown selected value from jquery to mvc3 action

I am trying to fill auto complete textbox based on dropdown selected value,
But unable to pass selected dropdown value as parameter to autocomplete url.Action()
Here is the code which I am using..
Dictionary<string, string> searchlist = new Dictionary<string, string>();
searchlist.Add("option1", "1");
searchlist.Add("option2", "2");
searchlist.Add("option3", "3");
searchlist.Add("option4", "4");
SelectList list = new SelectList(searchlist, "value", "key");
#Html.DropDownListFor(m => m.SearchType, list, new {#id="category", #class = "select" })
<script type="text/javascript">
$(document).ready(function () {
$("#category").change(function () {
var selectedVal = $("#category option:selected").text();
alert("You selected :" + selectedVal);
});
});
</script>
<input type="text" id="searchField" name="searchField" data-autocomplete-url="#Url.Action("Autocomplete", "Home", new { lang = Model.Language, cattype = selectedVal })" class="select" value="Search" onBlur="if(this.value == '') this.value = 'Search';" onFocus="if(this.value == 'Search') this.value = '';" />
<img src="#Url.Content("~/Content/images/magnifier.png")" alt="Search" title="Search" />
Please help me where am I going wrong.
Thanks in advance.
You should fire autocomplete when DDL change:
$(document).ready(function () {
$("#category").change(function () {
var selectedVal = $("#category option:selected").text();
//fire autocomlete
$('*[data-autocomplete-url]').each(function () {
$(this).autocomplete(
{
source: function (request, response) {
$.ajax({
url: $(this).attr('data-action'),
dataType: "json",
data: { lang : '#Model.Language', cattype : selectedVal },
success: function (data) {
response($.map(data, function (item) {
return {
label: item.Label,
value: item.Label,
realValue: item.Value
};
}));
},
});
},
minLength: 2,
select: function (event, ui) {
//do something
},
change: function (event, ui) {
if (!ui.item) {
this.value = '';
} else {
}
}
});
});
});
});
