Custom jquery validate messages for all errors -

how can specify custom error message each error type, required , date. want different message depending on error type.

i have field looks this

<input type="text" id="dateofbirth" name="dateofbirth" class="required date" />

my error messages this

this field required or please enter valid date

how can make following

date of birth required , please enter valid date date of birth

i'm using

var validator = $("form:first").validate({     errorclass: 'input_state_error',     rules: {         dateofbirth: "required date"     },     messages: {         dateofbirth: "please enter date of birth"     },     // errorplacement has take table layout account     errorplacement: function(error, element) {                         error.appendto($('#ctl00_lblmessage'));     },     // specifying submithandler prevents default submit, demo     submithandler: function() {         alert("submitted!");     },     // set class error-labels indicate valid fields     success: function(label) {         // set   text ie         label.html(" ").addclass("checked");     } }); 

following jquery date() documentation validation plugin, guess suggest this:

var validator = $("form:first").validate({     ...     messages: {         dateofbirth: {             required: "date of birth required",             date: "please enter valid date date of birth"         }     }     ... });
