Rails Trying to submit a form onchange of dropdown

Question

I have my Ajax working, builtin Rails javascript, with the submit button. However, I would like it to submit when I change the value of the dropdown box and eliminate the b

Answer 1

None of the solutions was working for me so I used the given below solution.

$("#q_dimension_id_eq").on("change", function (e) {
        $(this).closest("form").submit();
    });

Answer 2

For a select_tag, just add:

{:onchange => "myHandler();" }

where your handler will be:

this.form.submit();

Also, if onchange doesn't work you might want to try onChage with a capital C.

Finally, make sure NOT TO CONFUSE a select_tag with a form select.

See my answer to a similar question, only regarding a form select

Answer 3

A more general solution using jQuery (I don't need to know the name of the form) is:

onchange: "$(this).parent('form').submit();"

Answer 4

this.form.submit() will not work if form is remote: true and rails-ujs is in use. In that case, a regular submit will occur instead of XHR.

Instead you should:

onchange: 'Rails.fire(this.form, "submit")'

You can read here for more details.

Answer 5

This is what I was able to do to get it to work. I named the form switch_car by using :name => "switch_car" and used the following javascript.

:onchange => ("javascript: document.switch_car.submit();")

I am still looking for a better answer so I will updated if I find something. This doesn't use submit .js for some reason. It processes it as HTML unlike the submit button which uses AJAX to update only the changing page elements. But this is the best I have been able to find so far.
