Error on using alert in Javascript (Property 'alert' of object is not a function)

Question

I am just trying to use alert and put a string variable inside the alert and get an error:

Uncaught TypeError: Property \'alert\' of object [Object Window] i         


        

Answer 1

Somewhere in your code you overrode alert. Check for var alert = ... or some other kind of declaration like that. Also check for window.alert declarations.
