Obtain the correct form ID format that is dynamically loaded following the execution of an AJAX function

When adding dynamic HTML elements, it is recommended to use delegation binding. However, I am encountering an issue with getting the proper "id" of the form element.

$(document).on("submit", "form#add_education", function(e){
e.preventDefault();

        console.log($(this));
        $.ajax({
            url     : $(this).attr('action'),
            type    : $(this).attr('method'),
            data    : $(this).serialize(),
            dataType: 'json',
            success : function (json){

                    $('.view-educationsec').css('display','none');
                    $(this)[0].reset();
                    showEducation();

                    swal("Good job!", "Education saved successfully!", "success");
            },
            error: function(json){
                if (json.status === 422) {
                    // $("#errorMessage").text('There is an error occured. Please try again.');
                    swal("Something went wrong!", "Please contact the developer for this issue.", "error");
                } 

            }

        });


$("html").removeClass("no-scroll"); // para ma enable ang scroll sa browser

});

The Console.log output is correct, however, when running the ajax function, I encounter an error:

"Uncaught TypeError: $(...)[0].reset is not a function"

This issue is likely due to the improper format of the id used in the ajax call, which may also be causing problems with passing data to the controller.

Answer №1

Successfully found a solution, everyone. I included a variable for the form ID and assigned it to those utilizing it.

var form = $(this);

Updated code snippet

 $(document).on("submit", "form#add_education", function(e){
e.preventDefault();
var form = $(this);
$start_date = $("input[name=start_date]").val();
   $end_date = $("input[name=end_date]").val();


        console.log($(this));
        $.ajax({
            url     : form.attr('action'),
            type    : form.attr('method'),
            data    : form.serialize(),
            dataType: 'json',
            success : function (json){

                    $('.view-educationsec').css('display','none');
                    form[0].reset();
                    showEducation();

                    swal("Good job!", "Education saved successfully!", "success");
            },
            error: function(json){
                if (json.status === 422) {
                    // $("#errorMessage").text('There is an error occured. Please try again.');
                    swal("Something went wrong!", "Please contact the developer for this issue.", "error");
                } 

            }

        });


$("html").removeClass("no-scroll"); // enable browser scrolling


});

When using the $(this) within an AJAX call, it may not necessarily point to the form element that triggered the event. You can find some potential solutions in this related question.
