I am knew here so hi to everyone, I have been told by a friend that this site is particularly helpful so here goes.

I have a form that i want to ensure is filled out correctly before the user is able to proceed. I am also advised that Javascript is the easiest way to do this, however i have no idea how to implememnt it.

http://chimp.cc/start.htm

If the user fails to fill out the terms and conditions box with a "Yes"when the user clicks submit, i want a message to pop up to tell them to complete it.

and to return the user to that field for completion.

I honestly have no idea how to do this, can someone please help me.

I have attached the source code too.

Cheers

Andy

Hi chimp welcome to the forum.

I use a javascript popup that occurs when someone does not fill in the name for my guest book.

I guess you need the same sort of thing. If you want to learn how to do it there is a good tut at http://www.tizag.com/javascriptT/javascriptform.php for form validation.


for my site i added this code in the body

 <script type="text/javascript">

function formValidator(){
    var firstname = document.getElementById('moreInfo');
    if(emptyBox(firstname, "Please enter your name.")){
                            return false;
                        } else {
        return true;
    
}
}
      function emptyBox(elementJason, returnMessage) {
           if (elementJason.value.length == 0) {
                 alert(returnMessage);
                 elementJason.focus();
                 return true;
            } else {
              return false;
        }
        }
        </script>

and i used onsubmit="return formValidator()" in the form
and include the id="moreinfo" in the correct field.

ofcourse you will need to make a few ajustments inorder to use it on a checkbox.

btw its called a alert not a pop-up a pop-up is a seperate page in a seperate window what you want is a little box with text aka a alert...
