Why Doesn't Ajax and SweetAlert Show?

Question

Please help me, in my code, Ajax and SweetAlert worked perfectly, but now I get the error on pressing submit:

The Google chrome console shows below error:

Resource interpreted as Stylesheet but transferred with MIME type application/javascript: " http://localhost:8000/js/jquery-3.3.1.min.js ".

Any help is greatly appreciated.

Code

Answer 1

you have to use this js files,i hope its work for you.

<script src="{{ asset('assets/global/plugins/jquery.min.js') }}" type="text/javascript"></script>

<script src="https://unpkg.com/sweetalert/dist/sweetalert.min.js"></script>

example

$("#sub").click(function() {

var startDate = $('#fromDate').val();

var endDate = $('#toDate').val();

if (startDate !='')
{
    if(endDate == '')
    {
        swal("Error!", "Please Select To Date field", "error");

        return false;
    }

}
else
{
    swal("Error!", "Please Select From Date field", "error");

    return false;
}

if(startDate > endDate)
{
    //alert("Please Select To Date Grater Than"+startDate);
    swal("Error!", "Please Select To Date Grater Than "+startDate, "error");
    return false;
}  });

Answer 2

You have this line set to be a stylesheet but it is actually a .js file.

<link rel="stylesheet" type="text/css" href="{!! asset('js/jquery-3.3.1.min.js') !!}">

Try using:

<script src="{!! asset('js/jquery-3.3.1.min.js') !!}"></script>

Also, why are you including JQuery twice? Just move your second declaration to the top, the line that says:

<script src="//code.jquery.com/jquery-3.3.1.min.js"></script>

It needs to be declared before you add SweetAlert because SweetAlert is dependent on it.

EDIT: This is only a partial answer. OP still has another issue outside of this. Wanted to leave this up however as it was useful in solving part 1 of his problem.
