This might seem, very easy task. But then while making a customisable alert message, one need to think as to how to do it. While working on Cordova(phonegap), one can easily assume and which is true is the javascript alert script.

alert("Hello!");

The javascript alert will work. Then we do not have a customisation option except for the message. The solution Cordova provides is a function with the name as alert. The syntax is as below.

navigator.notification.alert(message, alertCallback, [title], [buttonName]);

In the very basic form, where one need to have a specific title, message and button name, the code I use is

navigator.notification.alert("My message", undefined,"My Alert", "ok");

Thats the simplest kind and if one need more generic, wrap the whole thing inside one of your own custom function as example below.

function showAlertWithTitle(title,message){
	navigator.notification.alert(message, undefined,title, "ok");
}

Hope coding.
