Confirming with JavaScript is actually quite easy. You can just use a simple if/else statement with it and then have something happen in each situation.

What we’ll be using is the function confirm(). The confirm function is set as a variable initially then you can use the associated variable to check the outcome of the confirmation. On the user end they get a small alert window with your question asked in it and either an “OK” or “Cancel” option.

So, to begin we need to define our confirm pop-up. For this example we’ll ask the user if they want a cookie.

var wants_a_cookie = confirm(“Would you like a cookie?”);

That will put up the window, however there will be no consequence whether they press OK or Cancel. That’s where the if/else comes into play. The confirm() function when acknowledged will return either TRUE or FALSE. What we can do is just have a situation for each option. For this example I’ll just have an alert pop up telling them if they or if they don’t want a cookie.

if( wants_a_cookie ){
alert(“Hooray! You want a cookie!”);
}
else{
alert(“Oh no, you don’t want a cookie!”);
}

And that’s it! If you want the entire code to copy into your file it would look like this:

<script language=“JavaScript” type=“text/javascript”>
var wants_a_cookie = confirm(“Would you like a cookie?”);
if( wants_a_cookie ){
alert(“Hooray! You want a cookie!”);
}
else{
alert(“Oh no, you don’t want a cookie!”);
}
</script>
