The problem:
Recently I've been modifying my Javascripts references in my project since they were repeting in several views (between the _Layout and views) causing errors.
At this moment there are no visible errors while working locally but once the project is online (thru Azure) the error 404: failed to load resource appears in the scripts section.
Information:
This is the current _Layout of the project:

As it can be seen, both the Development and Staging,Production enviroments have the references for jquery but for the purpose of this project I'll be working only with the references of the Development enviroment.
However, in the online version this errors show up:
I had these errors and it usually was because the jQuery was defined more than once in the view, or after a dependency such as bootstrap was declared, but this does not seem the case. As a consecuence none of the jQuery scripts is executing properly on the online version.
This is the result of the Network tab:
It looks like the jquery librery is being loaded correctly.
The following code is the source code of the view:

I have been trying to detect what could be wrong for the online version to produce some errors that were not shown while the project was tested locally but I haven't succeeded in trying to find out. Hope anyone can help me understand what could be wrong in this case.
Update:
For what I tested, it seems like jQuery works for a few seconds and then suddenly stops working but no error message related to this is displayed.
Note to mention, the error message appears at the top of the html too:
But that can be related to the fact that is missing these files:
回答1:
Why not just use a boolean var?
instead of
var global = this;
var wasclicked = 0;
Something like thise:
var isClicked = false;
$(document).ready(function () {
$("#modalbutton").on("click", function () {
isClicked = true;
});
$('#modal-action-store').on('hidden.bs.modal', function () {
isClicked = false;
});
$('#modal-action-store').on('shown.bs.modal', function () {
if (isClicked) {
var items = "<option value='0'>-- Seleccione Distrito --</option>";
$('#DistrictID').html(items);
}
$('#DepartmentID').change(function () {
var url = '/' + "Stores/GetDistrict";
var ddlsource = "#DepartmentID";
$.getJSON(url, { DepartmentID: $(ddlsource).val() }, function (data) {
var items = '';
$("#DistrictID").empty();
$.each(data, function (i, district) {
items += "<option value='" + district.value + "'>" + district.text + "</option>";
});
$('#DistrictID').html(items);
});
});
});
});
