Simple Popup Message based on jQuery Mobile - supports modal windows optionally (requires jqModal)

gistfile1.js

function jqmSimpleMessageRemove(dialogID) {
  /* optionally call this function to destroy a window made with jqmSimpleMessage
   * especially useful if your timeout val is long and the window is shown modally 
   */
  var dialog = $('#' + dialogID);

  if(!dialog)
    return;
    
  if(dialog.attr('_type') == 'modal') {
    clearTimeout(dialog.attr('_timerID'));
    //^ the timer may not exist anymore, but just in case...
    dialog.fadeOut(400, function() { $(this).jqmHide().remove(); });
  } else {
    dialog.fadeOut(400, function(){ $(this).remove(); });
  }
}

function jqmSimpleMessage(message, showLengthMS, modal) {
  /* Creates a simple message dialog.
   * Specify true for the modal param for the window to be created modally (no user input allowed)
   * NOTE: jqModal is required if modal is set to true
   */
  if(showLengthMS == undefined)
    showLengthMS = 800;
    
  if(modal == undefined)
    modal = false;
  
  //generate an ID for the dialog so we can do things like hide or remove it later  
  var dialogID = 'dialog_' + new Date().getTime();
  
  $("<div id='" + dialogID + "' class='ui-loader ui-overlay-shadow ui-body-b ui-corner-all'><h1>" + message + "</h1></div>")
      .css({
          display: "none",
          opacity: 0.96,
          top: window.pageYOffset + 100
      }).attr('_type', modal ? 'modal' : 'nonmodal').appendTo("body");

  var dialog = $('#' + dialogID);
  if(modal) {
    var t = setTimeout(function() { jqmSimpleMessageRemove(dialogID); }, showLengthMS);
    dialog.attr('_timerID', t);
    dialog.jqm({ modal: true}).jqmShow();
  } else {
    dialog.show().delay(showLengthMS).fadeOut(400, function(){ $(this).remove(); });
  }

  return dialogID; 
}
