Answer 1

post the code

Answer 2

without a code i could just suggest you something ...

1 - alert, prompt and confirm are written in lowercase
2 - if you haven't done yet try to use window.onload, ie:
window.onload = function(){
//you're code goes here;
alert("Hi!");
}

Answer 3

thanks, i was trying it in an android app called javascriot, and it always returns>> function not defind!

Answer 4

var result = confirm("Do you really want to leave this page?");
if (result == true) {
alert("Thanks for visiting");
}
else {
alert("Thanks for staying with us");
}

Answer 5

the code works, there aren't errors ... i don't know javascriot but could it be that it doesn't support native javascript?
what you've pasted is the full code or do you have any Dom reference?
