You should use chrome's or safari's built-in developer tools (ctrl+shift+i) to track JS errors and track actual AJAX requests.
First thank you gajendra. Bang and MÄris Kiseļovs give me your advices,I have konw what's wrong with my code,after I get a bad resault ,I trying to know what the $. Ajax get from xml exactly,so I use firebug check the div#contain I found that.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
