Hello all,

Im new to Javascript so i'm trying to learn from the beginning. i wrote this, as a first attempt, but no joy. can anyone help point me in the right direction/ guide me on what im doing wrong please.

Code:

<head>
    <title>Untitled Page</title>
    <script type="text/javascript">

        function myfunction() {
            var d = new date();
            var day = d.getDate();
            if (day == 2) {
                alert("Tuesday")
            }
            else { 
                alert("some other day")
            }
        }

        
    </script>
</head>
<body>

<button type="button" onclick="myfunction()"> click me</button>

</body>
</html>

Your help as always is greatly appreciated.

Kind regards
MG

"getDate" returns the day of the month, i.e. 1 to 31. "getDay" will return 0 to 6 for the day of the week.

Hi, thanks for the reply.

I changed it to 'getDay', but that doesnt work either

Code:

        function myfunction() {
            var d = new date();
            var day = d.getDay();
            if (day == 2) 
            {
                alert("Tuesday")
            }
            else 
            { 
                alert("some other day")
            }
        }

regards

What if you wrote
var d = new Date();
with capital D?

Hi, thanks for the post.

So i changed it slightly and now its kind of working. the new code looks like this:

Code:

           var d = new date();
            var day = d.getDay();
        function myfunction() {
            
            if (day == 2) 
            {
                alert("Tuesday");
            }
            else 
            {
                alert("some other day");
            }
        }

As you can see the variables are now outside the function, but i thought that shouldnt matter? you can put variable in functions right?

but now it displays "some other day" ? isnt tuesday the number 2 from 0-6 using the getDay() method??

Kind regards
MG

Yes, you can, and, maybe should, define variables inside functions!
I've tried your code in my browser, and replaced
new date();
with
new Date();

It complained "date is not defined"; changed it to Date - happy browser.

best

Hello, cheers for reply.

I changed it like yourself, and now it works. I think it may have been due to it not being a capital 'D'. Caps hey!? :-).

thank you all for your help. You've been a real help as always.
