[jquery] form confirm before submit

I am using a simple form and I want to allow the user to confirm before the form submits... I know this would be easy using jQuery, but I am a bit confused about code...

$(function() {
  $(".testform").submit(function() {
    $('.submitbtn').text('confirm');
  });
});

I know that the above code is not complete and I would like your help to finish it, so it would give an alert (using jQuery alert) that says 'Please confirm if everything is correct' and changes the text on the submit button to "confirm" instead of "submit". If the user clicks confirm again it would submit the form. I hope this makes sense. thanks.

Based on easy-confirm-plugin i did it:

(function($) {
    $.postconfirm = {};
    $.postconfirm.locales = {};
    $.postconfirm.locales.ptBR = {
        title: 'Esta certo disto?',
        text: 'Esta certo que quer realmente ?',
        button: ['Cancela', 'Confirma'],
        closeText: 'fecha'
    };
    $.fn.postconfirm = function(options) {
        var options = jQuery.extend({
            eventType: 'click',
            icon: 'help'
        }, options);
        var locale = jQuery.extend({}, $.postconfirm.locales.ptBR, options.locale);
        var type = options.eventType;
        return this.each(function() {
            var target = this;
            var $target = jQuery(target);
            var getDlgDv = function() {
                var dlger = (options.dialog === undefined || typeof(options.dialog) != 'object');
                var dlgdv = $('<div class="dialog confirm">' + locale.text + '</div>');         
                return dlger ? dlgdv : options.dialog;          
            }           
            var dialog = getDlgDv();
            var handler = function(event) {
                    $(dialog).dialog('open');
                    event.stopImmediatePropagation();
                    event.preventDefault();
                    return false;
            };
            var init = function() 
            {
                $target.bind(type, handler); 
            };
            var buttons = {};
            buttons[locale.button[0]] = function() { $(dialog).dialog("close"); };
            buttons[locale.button[1]] = function() {
                $(dialog).dialog("close");
                alert('1');
                $target.unbind(type, handler);
                $target.click();
                $target.attr("disabled", true);
            };            
            $(dialog).dialog({
                autoOpen: false,
                resizable: false,
                draggable: true,
                closeOnEscape: true,
                width: 'auto',
                minHeight: 120,
                maxHeight: 200,
                buttons: buttons,
                title: locale.title,
                closeText: locale.closeText,
                modal: true
            });
            init();
        });
        var _attr = $.fn.attr;
        $.fn.attr = function(attr, value) {
            var returned = _attr.apply(this, arguments);
            if (attr == 'title' && returned === undefined) 
            {
                returned = '';
            }
            return returned;
        };
    };
})(jQuery);

you only need call in this way:

    <script type="text/javascript">     
        $(document).ready(function () {
            $(".mybuttonselector").postconfirm({ locale: {
                        title: 'title',
                        text: 'message',
                        button: ['bt_0', 'bt_1'],
                        closeText: 'X'
                    }
                });
        });
    </script>

var r = confirm('Want to delete ?'); 

if (r == true) { 
    $('#admin-category-destroy').submit(); 
}

$('#myForm').submit(function() {
    var c = confirm("Click OK to continue?");
    return c; //you can just return c because it will be true or false
});

HTML

<input type="submit" id="submit" name="submit" value="save" />

JQUERY

$(document).ready(function() {
    $("#submit").click(function(event) {
        if( !confirm('Are you sure that you want to submit the form') ){
            event.preventDefault();
        } 

    });
});

Here's what I would do to get what you want :

$(document).ready(function() {
    $(".testform").click(function(event) {
        if( !confirm('Are you sure that you want to submit the form') ) 
            event.preventDefault();
    });
});

A slight explanation about how that code works, When the user clicks the button then the confirm dialog is launched, in case the user selects no the default action which was to submit the form is not carried out. Upon confirmation the control is passed to the browser which carries on with submitting the form. We use the standard JavaScript confirm here.

<body> 
    <form method="post">
        name<input type="text" name="text">
        <input type="submit" value="submit" onclick="return confirm('Are you sure you want to Save?')">
    </form>
</body>

$('.testform').submit(function() {
  if ($(this).data('first-submit')) {
    return true;
  } else {
    $(this).find('.submitbtn').val('Confirm').data('first-submit', true);
    return false;
  }
});

Simply...

  $('#myForm').submit(function() {
   return confirm("Click OK to continue?");
  });

or

  $('#myForm').submit(function() {
   var status = confirm("Click OK to continue?");
   if(status == false){
   return false;
   }
   else{
   return true; 
   }
  });
