offset.top value different in document ready and console.log() why?

问题

in my case, my about page is parallax moving well every section when i'm click on about's sub menu (submenu for same page #link). but in my site home page has the same submenu if somebody click on the submenu first goto about page then the exact position. I make it almost done. but offset().top not giving me the exact value. so I stuck.

I console to see offset.top value when document ready..

help me to understand why this happen???

thanks in advance. sorry for poor english

my site is here http://doitte.com/delatest/

this is because on document ready some of the content may have not got their height. This could be due to resources such as images, font-faces, delayed css/js loading etc.

Instead of using $(document).ready(); go for $(window).load();
