Question

I have a form below; I have changed the submit button to just type “Button” so I would be able to run some JavaScript before submitting the form:

Here is my form:

<form action="/Cart" method="post">
     <input type="hidden" name="name" value="12" />
     <input type="button" class="addToCartButton" value="Add to Cart" />
 </form>

Here is my initial event handler:

$(document).ready(function () {
    $('.addToCartButton').click(function () {

       //need to reference current form here
       //need to reference the hidden input with name="Name" above
    });
});

I have a number of these forms on the same page so I need to relatively reference the form and some other inputs inside that form. What is the best way to doing it? I was thinking about putting some prefix that would be unique to each form and then using that in the selector but that seems very hacky …

This should work:

$(document).ready(function () {
    $('.addToCartButton').click(function () {

       //need to reference current form here
       $(this).closest('form');
       //need to reference the hidden input with name="Name" above
       $(this).closest('form').find('input[name="name"]');
    });
});
