Hey,

I'm currently developing an online work brief, where the user has to
enter details regarding the project into a form. I've come to a section
in the form where the user has the option of selecting  between two
checkboxes and an input element. I have to ensure that at least one of
the checkboxes have been checked or that the input element is not
empty. I've come up with this function:

function validateMedia(){
    var count = 0;
    if(document.workBrief.mediaOnline.checked){
        count++;
    }
    if(document.workBrief.mediaPrint.checked){
        count++;
    }
    if(document.workBrief.mediaOther.value != ""){
        count++;
    }
    if(count > 0){
        return true;
    }else{
        alert('Please choose at least one media option');
        return false;
    }
}

I'm sure there is a more effiecient way of writing this.

You thoughts are much appriciated :)
