The most frequent dialogs are alert, confirm and prompt. In the case of an alert you just need to display a message to the user
and require no feedback besides user acknowledgement. Confirm dialog has similar purpose, but expects from the user a response
by accepting or declining the message. Prompt waits for user input. The w2ui library includes these dialogs for your convenience.
w2alert(msg, [title], [callBack])
The alert dialog can be called in the following way:
First argument, msg, is a message to display. Second optional argument, title, is the title for the dialog. The third optional argument,
callBack, is a call back function when dialog is closed.
w2confirm (msg, [title], [callBack])
The confirm dialog can be called in the following way:
The method takes up to three arguments w2confirm(msg, [title], [callBack]), where msg is the message to display. You can optionally supply title for the message and a call back function.
You can optionally call w2confirm passing an object with options. This options object has following structure:
For convenience, w2confirm will return to you an object with yes() and no() methods that you can use in the following way:
w2prompt(label, [title], [callBack])
Prompts user to enter value. Instead of passing label, title, and callBack, you can call w2prompt in the following way:
