Question

I am trying to make my own confirm dialogs with two parameters.

function myAlert(message, adr) {
    jConfirm(message, 'Confirmation Dialog', function(answer) {
        if (answer){
            window.location = adr;
        }

    });
}

$(document).ready(function() {
  $.rails.confirm = function(mess, mess2) {
      return myAlert(mess, mess2);
  }
});

And in view:

<%= link_to 'Delete', 
        {:controller => 'controller_name', :action => 'action_name'},
         :confirm => {"xxxxxxx", "aaaaaaaa"} %>

And in alert message I will get following:
xxxxxxxaaaaaaaa

What I am doing wrong? Why I don’t get only xxxxxxx? Why are the strings merged?

PS: the first parameter in jConfirm function display the message to confirm window.

Answer 1

I believe :confirm is a string argument only. I’m a bit surprised, because :confirm => {"xxxxxxx", "aaaaaaaa"} should throw a syntax error if I’m not mistaken.

If you want to pass two parameters, you could store them in separate data attributes and roll your own confirmation method, something like this:

<%= link_to 'Delete', 
      :controller => 'controller_name', :action => 'action_name', :class => "confirm",
      :data-foo => "bar", :data-bar => "foo" %>

$('a.confirm').click(function(){
  return myAlert($(this).data('foo'), $(this).data('bar'));
});

Or you comma-separate your arguments and split them using JS:

… :confirm => "foo,bar" …

$.rails.confirm = function(message) {
  var messageParts = message.split(',');
  return myAlert(messageParts[0], messageParts[1]);
}
