Help! Special input validation with JavaScript

Hi,

I need help with Javascript validating input in some fields in my form.

  1. When a user chooses alt1 from a radiobutton field (service) a serviceAllt1 subform will be opened and the fieldA & fieldB must be entered.

  2. When a user chooses alt2 from a radiobutton field (service) a serviceAllt2 subform will be opened and the fieldC & fieldD must be entered.

  3. When a user chooses alt3 from a radiobutton field (service) a serviceAllt3 subform will be opened and the fieldE & fieldF must be entered.

Note! I have a Notes submit button not JavaScript submit code.

How to make this work fine? Please I need detailed help, I tried many times but nothing happen.

I appreciate any help!

hi

you can use this code on radion button click event

function valbutton(thisform) {

// place any other field validations that you require here

// validate myradiobuttons

myOption = -1;

for (i=thisform.myradiobutton.length-1; i > -1; i–) {

if (thisform.myradiobutton[i].checked) {

myOption = i;

}

}

if (myOption == -1) {

alert(“You must select a radio button”);

return false;

}

alert("You selected button number " + myOption

  • " which has a value of "

  • thisform.myradiobutton[myOption].value);

// place any other field validations that you require here

thisform.submit(); // this line submits the form after validation

}

u can test like this by

if(thisform.myradiobutton[myOption].value==“ALt1”

{

         something to happen

}

if
