if I have a form, and in this form I have a checkbox called chkVerify, how do I write code to make sure that the box is indeed checked and if not check... give the user an alert telling them they need to check the box ?
Click to See Complete Forum and Search --> : Verify if a box is checked

No, but this does:
if document.yourformname.chkVerify.checked!=true)
{alert("Please check the checkbox");}
All you need to do is change the text yourformname to the name of your HTML form.
if document.yourformname.chkVerify.checked!=true)
{alert("Please check the checkbox");}
All you need to do is change the text yourformname to the name of your HTML form.

Try this instead:<html>
<head>
<title>Untitled Document</title>
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
<script>
function verify(){
if (document.myForm.chkVerify.checked!=true){
alert("Please check the checkbox");
return false;
}else{
return true;
}
}
</script>
</head>
<body>
<form action="http://www.yahoo.com" method="POST" onsubmit="return verify();" name="myForm" id="myForm">
<input type="checkbox" name="chkVerify" value="1">
<input type="submit" name="action" value="Submit">

}else{
return true;
}
}
</script>

Sure, go ahead and ask away. :) The best way to learn is to ask questions... ;)

I am reading about cookies.
if I want to make my name be the cookie value, and I want to have the cookie expire in 30 days, but renew the 30 day expiration day each time I visit the page, how do I do this ?
do I have to post a new thread because it is a new topic ... or can we just continue with this one ?

Ok, first of all, this question is fine in this thread, but you might as well post a new thread with unrelated questions. That way there aren't threads that have unrelated topics. ;) Anyway...
You need to check if the cookie exist when someone comes to your site. If it doesn't exist, you set it, and if it does exist, you change the experation date to 30 days from the present. That is basically the method behind it... If you can't get it to work, let me know. ;)

yes, he did... and it was great, but, I guess I am a slow learner because I am still having trouble with it...
that is why I am starting again, only with less information.
maybe this time I will get it.

You could reference back to what Dave Clark taught you. That should help you plenty.

I still have it... and will go back through it again... I have been doing that...
it has so much information on it.... that it is hard for me to tell what editing I need to do to it to get it to do what I want it to...
I have written it at least five times, and am certainly doing something wrong.
he is a great teacher... it is me... it takes me a long time to learn some things.... and sometimes need to be shown again.
I go over that code a lot.. just trying to understand what each part means.
