Answer 1

you have to add a custom validation rule for text box . which checks the check box value and the drop down value.

in your form validation

textbox: {
      required: true,
      custom_rule : true
       }

then

$.validator.addMethod("custom_rule", function(value, element) {

var dropdown_val = $("#dropdown").val();

if((dropdown_val==0 && value>0) || (dropdown_val==1 || dropdown_val==2 ) && value==0))
{
   return true;
}
else
{
   return false;
}


}, "if drop down 0 , input should greater than 0 , else input should be 0");
