4+
5+
Creates a modal dialog to give a waiting feedback to users
6+
You can only show and dismiss the dialog, it will block user interactions. You can set the text appearing in the dialog
7+
8+
**NOTE:** this is not a progress dialog, you can not show progress
9+
10+
// To SHOW a modal waiting dialog
11+
window.plugins.waitingDialog.show("Your dialog text");
12+
13+
// To HIDE the dialog
14+
window.plugins.waitingDialog.hide();
15+
16+
If you want to show a waiting dialog for a certain amount of time, you can use javascript setTimeout
17+
18+
// show dialog
19+
window.plugins.waitingDialog.show("Your dialog text");
20+
// automatically hide dialog after 5 seconds
21+
setTimeout(function() {window.plugins.waitingDialog.hide();}, 5000);
