When an ajax form is submitted, the page gets refreshed automatically

Question

When an ajax form is submitted, the page gets refreshed automatically

I am currently working on a project and trying to make a call to a controller function without triggering a page refresh. I have attempted setting up an ajax function for this purpose, but unfortunately, it has not been successful so far. I have tried placing the related script in both the HTML file and a separate jQuery.js file, but it seems like the form submission is not hitting the script at all. Any assistance on this matter would be highly appreciated! The form is located in a cshtml file, the controller in .cs, and the script in .js

The form in discussion:

<form id="tableForm"  action="@(Url.Action("AddToOrder", "Order"))" method="post">
                                    @{foreach (var item in (IList<Item>)ViewData["items"]){
                                    <input type="hidden" id="@("item_id_" + item.id)" name="@("item_id_" + item.id)" value="@item.id" />
                                    <tr>
                                        <td>@item.description</td>
                                        <td>@String.Format("{0:C}",item.price)</td>
                                        <td><input type="text" id="@("item_quantity_" + @item.id)" name="@("item_quantity_" + @item.id)" style="width: 50px;" value="0" /></td>
                                     </tr>
                                      }}
                                    <tr>
                                        <td><input class="submit" type="submit" value="Add item(s) to order" /></td>
                                    </tr>
                                </form>

The script causing issues:

$('#tableForm').submit(function (e) {
e.preventDefault();
    $.ajax({
        type: "POST",
        cache: false,
        url: $(this).attr('action'),
        data: $(this).serialize(),
        succes: function (data) {
            alert(data);
        },
        error: function (jXHR, textStatus, errorThrown) {
            alert(errorThrown);
        }
    });
});

In summary, although the controller and method are functioning properly, the form submission results in a page refresh.

Make sure to include the following code snippet in your script and remember to call the preventdefault function after submitting:


$('#tableForm').submit(function (e) {
    $.ajax({
        type: "POST",
        cache: false,
        url: $(this).attr('action'),
        data: $(this).serialize(),
        success: function (data) {
            alert(data);
        },
        error: function (jXHR, textStatus, errorThrown) {
            alert(errorThrown);
        }
    });
    e.preventDefault();
});

Have you checked if your AJAX method is being triggered when the page is submitted? Consider including an alert to verify this. Another suggestion is to include ClientIdMode="Static" in your form tag, especially if it is within a master page, as this will ensure that the control ID remains static and can be bound to by JavaScript.

Using the clientidmode attribute might solve the issue. Please keep me updated if it doesn't work.

Based on the information provided, it seems like your issue may stem from including your .js file at the top of the page or within the head element.

This causes the code snippet $('#tableForm') to result in an empty jQuery object because it executes before the referenced form element is loaded.

To resolve this, consider moving your JS code to the end of the body element or wrapping it in a DOM-ready event handler to ensure safe access to the DOM:

$(function(){
   // Your jQuery code here for secure DOM manipulation
});

This can also be written as:

$(document).ready(function(){
   // Your jQuery code here for secure DOM manipulation
});

Your updated code will look something like this:

$(function(){
    $('#tableForm').submit(function (e) {
        e.preventDefault();
        $.ajax({
            type: "POST",
            cache: false,
            url: $(this).attr('action'),
            data: $(this).serialize(),
            success: function (data) {
                alert(data);
            },
            error: function (jXHR, textStatus, errorThrown) {
                alert(errorThrown);
            }
        });
    });
});

If issues persist, check for any preceding JavaScript errors such as missing jQuery library references by examining your entire webpage.
