DOM scriptiing
Hi Guys,
I'm trying to validate my form and loop thorugh each checkbox to see if it has been checked. My html is below, Im trying to get the length of the checkbox array by using: alert(document.form.transport.length); However, it keeps saying it has no properties, can anyone please ? Thankyou <ffform name="form" action="#" method="post" onSubmit="return CheckFieldBlank()"> <input id="Bycycle" type="checkbox" name="transport" value="Bycycle" /> <input id="Motorscooter" type="checkbox" name="transport" value="Motorscooter" /> <input id="Motorbike" type="checkbox" name="transport" value="Motorbike" /> <input id="Car" type="checkbox" name="transport" value="Car" /> </form> |
