Confirmation before submitting form using jQuery

I am trying add a confirmation before a form is submitted using jQuery. I found a nice example in another Stack Overflow question form confirm before submit but I can't get it to work.

jQuery:

$(function() {
    $('form#delete').submit(function() {
        var c = confirm("Click OK to continue?");
        return c;
    });
});

Template:

<form id="delete" action="{% url 'item_delete' item.id %}" method="post">{% csrf_token %}
    <input class="floatright" type="submit" value="Delete" />
</form>

How can we achieve this?

You are submitting the form and after are checking for confirm, you need to the inverse

JS:

$(function() {
   $("#delete_button").click(function(){
      if (confirm("Click OK to continue?")){
         $('form#delete').submit();
      }
   });
});

HTML:

<form id="delete" action="{% url 'item_delete' item.id %}" method="post">{% csrf_token %}
    <input id="delete_button" class="floatright" type="button" value="Delete" />
</form>
