I am trying to write a validation script for a form question that requests an explanation (in a text box) if a particular radio button is selected:
- Do you communicate directly with others you met via message boards? (e.g., by email, instant messenger, phone, etc) NO YES
If yes, please specify the mode of communication:
Current script is:
radioOption = -1;
for (i=0; i<document.forms[0].question4.length; i++) {
if (document.forms[0].question4.checked) {
radioOption = -1;
break;
}
}
if (radioOption == -1) {
window.alert ('You didn\'t finish answering Question 4');
return false;
}
if (document.forms[0].question4.checked == true && document forms[0].question4_explain.value == "") {
window.alert ('You didn't specify the type of communication in question 4!');
return false;
}
How do I change this last part to be specific to value 2 for the radio button rather than any value selection requires an explanation? (how do I require that the text box be completed only if yes is selected?)
