    form validation of text fields and checkbox

    CarolinaTigerRescue Community Member

      I have Dreamweaver CS3.  My form includes several field validations on text boxes and I was able to use a behavior on the form tag to validate my text fields, but I also have a Terms and Conditions checkbox that I need to validate as Checked.  Everything I have found online suggests using a spry checkbox to validate, but this seems to conflict with the code that is validating the text fields.


      How can I validate my checkbox as well?




      (in header)

      function MM_validateForm() { //v4.0

        if (document.getElementById){

          var i,p,q,nm,test,num,min,max,errors='',args=MM_validateForm.arguments;

          for (i=0; i<(args.length-2); i+=3) { test=args[i+2]; val=document.getElementById(args[i]);

            if (val) { nm=val.name; if ((val=val.value)!="") {

              if (test.indexOf('isEmail')!=-1) { p=val.indexOf('@');

                if (p<1 || p==(val.length-1)) errors+='- '+nm+' must contain an e-mail address.\n';

              } else if (test!='R') { num = parseFloat(val);

                if (isNaN(val)) errors+='- '+nm+' must contain a number.\n';

                if (test.indexOf('inRange') != -1) { p=test.indexOf(':');

                  min=test.substring(8,p); max=test.substring(p+1);

                  if (num<min || max<num) errors+='- '+nm+' must contain a number between '+min+' and '+max+'.\n';

            } } } else if (test.charAt(0) == 'R') errors += '- '+nm+' is required.\n'; }

          } if (errors) alert('The following error(s) occurred:\n'+errors);

          document.MM_returnValue = (errors == '');

      } }


      (in body)

      <form action="https://faas.cloud.clickandpledge.com" method="post" id="Donation" onsubmit="MM_validateForm('NameOnCard','','R','CardNumber','','R','Cvv2','','R','BillingF irstName','','R','BillingLastName','','R','BillingPhone','','R','BillingEmail','','RisEmai l','BillingAddress1','','R','BillingCity','','R','BillingPostalCode','','R');return document.MM_returnValue">


      (checkbox that needs validation)

      <input name="Terms" type="checkbox" />
