You can use the form below edit the configuration, and get a rendered preview of the JavaScript necessary to create a popup with your options, then when you're, done press the open button at the bottom of the page and preview how the popup looks!
This will create the JavaScript config object for each of the attributes you provide, however the test popup will only include 'Title', 'Message', 'Buttons', and 'Class'. The attributes for posting or reloading are not created for this example.
