Validation may be made conditional based on the state of another element, such as a radio button.
Create a function to test the state of the radio button. The following example tests a Commerce Service Center radio button:
atg.commerce.csr.rule0 = function () { return
document.getElementsByName('addressType')[0].checked; };Reference the function from the
validateIfattribute on the widget:<dsp:tagAttribute name="validateIf"
value="atg.commerce.csr.rule0.apply()"/>
Validation rules of the widget will be applied conditionally only when the referenced function returns true.
