Javascript if-else is malfunctioning

I am having difficulty running the code below which contains if statements. I have tried removing some parts of it, but still can't get the alert to show up. Any advice would be highly appreciated. Thank you.

<!DOCTYPE html>
<html>
<body>
    <script>
        var a = "am";
        var c = 8; 
        var d = 7;

        if(a == a)
        {
            alert("1st if");
            if(c > d)
            {
                alert("2nd if");
                return false;
            }
            else
            {
                alert("1st else");
            }
        } 
    </script>      
</body>
</html>

Answer №1

I'm unsure of the intention behind the "return false" statement. However, it seems like removing it will allow the if-else statement to function correctly.

UPDATE: Keep in mind that the "return" statement should be utilized within a function - you can encapsulate your if statements within a function declaration or even an immediately-invoked anonymous function.

Below is a sample code snippet demonstrating the alert messages:

var a = "am";
var c= 8; 
var d= 7;
(function (){
    if(a == a)
    {
        alert("1st if");
        if(c > d)
        {
            alert("2nd if");
            return false;
        }
        else
        {
            alert("1st else");
        }
    }
})();
