why use different methods to set an input field or submit button disabled?

$("#search").prop("disabled",true); and $("#submit").attr("disabled",true);

why not use .prop() on the submit button?

HI Zoe Xiao

You are correct. They should both use jQuery's prop() method. The attr() method still works, but should be used to set HTML attributes like href and src not properties like disabled or checked.
