Question

How can I change submit button on form to text?

<%= f.submit "Text" %>

I know how to change text on button but I need to change a way to submitting.
You can press on link, for example Submit and submit.

Answer 1

In order to change the submitting of a form to be triggered by a link as opposed to a submit button, you must use javascript instead of raw generated HTML only.

See similar answers on StackOverflow but a summary of a possible solution in jQuery (which comes baked into recent versions of Rails) would be as follows:

$('#submit_link').click(function(){
    $('form').submit();
    return false;
});
