javascript - How to validate user input is current date and time? -


in html use ext.net datefield 

 <ext:datefield runat="server"  id = "date"  format="y-m-d hh:mm:ss" submitformat="y-m-d h:i:s"  marginspec="0 0 0 60" fieldlabel="gate in date/time" allowblank="false" indicatortext="*" indicatorcls="red-text"/>

when view shows correct date time 12:00:00.in javascript 

var iframeid = $('iframe').attr('id');  var mydate = lazymethod_get(iframeid, "formdetail", "date") var today = new date().toisostring().slice(0, 10);   alert(mydate); alert(today);  if (mydate > today) {     alert("entered date greater today's date "); } else {     alert("entered date less today's date "); }}

the validation alert date entered less today date. want validate date , time if user insert example 2016-02-03 date wrong , current date.

thank you.

time in microseconds.

if (!date.now) {   date.now = function now() {     return new date().gettime();   }; }

do formatting after calculations.

what lazymethod_get() workings. returning string, or date object.

scala - 'wrong top statement declaration' when using slick in IntelliJ -

Image
i'm porting project scala 2.9 2.10, therefore have use slick instead of scalaquery. i'm using slick 2.1.0 since supports ms access. according this tutorial , upgrade guide changed robs object class , added val robs : why error message wrong top statement declaration , how rid of it? edit: i'm new scala... according this question seems can't put val outside of methods or classes, right? code above directly in packge. right approach slick then? should move code in class or trait? according this changed val robs = tablequery[robs] to object robs extends tablequery(new robs(_)) {} . no warnings or errors anymore. :)
