jQuery submit handler with Rails

Question

I'm trying out jQuery with Rails and I faced this problem. I want to have a jQuery submit handler for a button_to tag like this

<%= button_to "+", action: "execute", operation: "add", operand: "1" %>

which is actually converted to a form in the DOM like so

<form class="button_to" method="post" action="/execute?operand=1&amp;operation=add">
<input type="submit" value="+">
<input type="hidden" name="authenticity_token" value="mre8xqU4RBk2u+vCLrMQHYUHTNWtk0Ebn45OnvlXxUZcofqxArt9ZXJN63QlNq8Kei08FFo6Y4+OQgwH+vsVNw==">
</form>

I added a submit handler for this form which looks like this

$(document).ready(function(){
  ("form").submit(function(){
      alert("here");
    });
});

The alert doesn't get displayed when I submit the form. I also tried the solution of this question but it didn't help.

My aim is to set the value of the value of the operand attribute in the button_to tag to $(".operand").text() inside the submit handler. Operand is another text field in which the user has entered a numeric value.

Looks like you're missing a '$'

  ("form").submit(function(){
      alert("here");
   });

Should be

  $("form").submit(function(){
      alert("here");
  });
