datepickerメソッドを使いたくない人には

var alldatepicker=  $("[class$=hasDatepicker]");

alldatepicker.each(function(){

var value=$(this).val();

var today = new Date();

var dd = today.getDate();

var mm = today.getMonth()+1; //January is 0!

var yyyy = today.getFullYear();

if(dd<10) {

    dd='0'+dd

} 
if(mm<10) {

    mm='0'+mm

} 
today = mm+'/'+dd+'/'+yyyy;
if(value!=''){
if(value>today){
alert("Date cannot be greater than current date");
}
}
});
