Use jQuery Mobile $.mobile.showPageLoadingMsg() for other messages/notifications

gistfile1.js

var default_msg = $.mobile.loadingMessage; // set this outside function scope so we can access it later

// you must provide a msg argument.  The delay and theme arguments are optional.
function show_hide_message = function(msg,delay,theme) {
  if (typeof(delay)==='undefined') {
    var delay = 3500; // in milliseconds
  }
  if (typeof(theme)==='undefined') {
    var theme = 'a'; // default theme; setting this to 'e' is nice for error messages
  }
  var css_class = '';
  if (theme==='e') {
    css_class = 'ui-body-e';
  }
  $.mobile.loadingMessage = msg;
  $.mobile.showPageLoadingMsg();
  $(".ui-loader").addClass(css_class).find(".spin:visible").hide(); // hide the spinner graphic
  setTimeout(
    function() {
      $(".ui-loader").removeClass(css_class).find(".spin:hidden").show(); // show the spinner graphic when we are done
      $.mobile.hidePageLoadingMsg();
      $.mobile.loadingMessage = default_msg; // reset back to default message
    }, 
    delay
  );
}

Note, for the flash[:notice] messages, I used theme 'e', which looks good for error messages.

Also, see my fork of jQuery Mobile which adds support for HTML markup in the loading message.

If the only reason you need underscore.js is to provide delay() support then window.setTimeout(fn, delay); will do the same as you don't have any extra parameters to pass

I thought that,too, after I had been away from computer. Thanks for the feedback! UPDATE: I removed UnderScore.js dependency and used setTimeout(). I also forgot to include code to set default page loading message so we can set it back to default when we are done.

Is there anywhere a link to an adequate RoR example which uses this function?

Here is a link to see it in action: http://singapore.highpoint.edu/tix/login

You can simulate a bad login by entering '123' in the barcode field.

You will briefly see the familiar ajax busy dialog for jQuerymobile.

Then you will get an error message about a login failure -- the sort of message that is typical for flash[:notice].

The error message is the ajax busy dialog w/ an alternate message, alternate theme, and with the animated GIF hidden.
