a standard validate form function

[tonyx666]

hi.. someone kindly gave me the below script that makes sure one of my radio buttons is checked before the user can press submit.. my question is this..
is there a basic procedure that i can use that will place rules on the other form inputs..

so if they do not choose an item from a drop down.. or do not write text in a textbox.. and so on.. also can all of these commands be placed in one function.. as opposed to wrting a separate function for each part of the form validation..

if someone could show me a general snippet that is not to hard to manipulate i would be very grateful.. thanks..

<script type="text/javascript">
			<!--
			function doRedirect()
			{
			var groupValue;
			var myOption = -1;
			for (i=document.form.r1.length-1; i > -1; i--) {
			if (document.form.r1[i].checked) {
			groupValue = document.form.r1[i].value;
			myOption = i;
			}
			}
			if (myOption == -1) {
			alert("You must select an option. \n e.g: Take me to Heathrow");
			return false;
			}
			else {return true;}
			}
			-->
		</script>

Make sure this:
[tt] onsubmit="[blue]return[/blue] IsFormComplete()"[/tt]

Also take out the semo-colon after the closing curly bracket of the function. It is a left-over of my previous incomplete editing. ([tt]}[highlight];[/highlight][/tt])

ok with this

function IsFormComplete()
{
    var FormOk  = true;

    if (document.EnquiryForm.ContactName.value == '')
    {
        alert('Please enter a '+document.EnquiryForm.ContactName.name +'.');
        document.EnquiryForm.ContactName.focus();
        FormOk = false;
        return FormOK;
    };
    
    if (document.EnquiryForm.EmailAdd.value == '')
    {
        alert('Please enter a '+document.EnquiryForm.EmailAdd.name +'.');
        document.EnquiryForm.EmailAdd.focus();
        FormOk = false;
        return FormOK;
    };


    return FormOk;
}
