jquery - Why does $(document).height() return too high number? -


i alerting document height:

alert($(document).height());

the result 3307px while full web page has 1800px.

from other answers here on so, learned needed check doctype did , looks this:

<!doctype html public "-//w3c//dtd xhtml 1.0 transitional//en" "http://www.w3.org/tr/xhtml1/dtd/xhtml1-transitional.dtd">

any idea why can document height show higher number expected?

there no hidden elements in page, or that.

edit: reason showing high number @ time of me retrieving document height, menu, containing elements increased overall height.

try : 

alert($(window).height());

if want , browser window height;

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

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. :)
