Loading ...Validating dates of birth are a common task on websites that have content available only for users 18+ years old. Using jQuery, this is very easy to do, as shown in the following example:
$("#lda-form").submit(function(){
var day = $("#day").val();
var month = $("#month").val();
var year = $("#year").val();
var age = 18;
var mydate = new Date();
mydate.setFullYear(year, month-1, day);
var currdate = new Date();
currdate.setFullYear(currdate.getFullYear() - age);
if ((currdate - mydate) < 0){
alert("Sorry, only persons over the age of " + age + " may enter this site");
return false;
}
return true;
});
