Hi all,
how to validate select field as mandatory only when it's corresponding text field is entered?
For example
<aui:form name="temp">
<aui:input type="text" name="temperature"/>
<aui:select label="" name="unit">
<aui:option value="" >--select--</aui:option>
<aui:option value="hello">Celcius</aui:option>
<aui:option value="hello hi">Fahrenheit </aui:option>
</aui:select>
<aui:input type="submit" name="submit"/>
</aui:form>

Note:It is not mandatory that always temperature should be entered

Hi,
thank you for the reply. I know how to validate select as required. But I want to know how validation on select will be done only when the text field(temperature) is entered.

I may be a little late here...

try to think it like this:
instead of saying 'this field is always required' like in 'required: true' you should say 'this field is required when temperature is set'

function isTemperatureSet(){ 
    if( $('#temperature').val() != ""){
        return true;
    }
    return false;
}

var rules = {
   <portlet:namespace />unit: {
       required: isTemperatureSet  
   }
};

please be aware i'm using jQuery in my answer to get the value of the temperature field.. plus,

  if( $('#temperature').val() != "")

does not work for whitespaced strings, etc
