java QQ 캡처 모방 기능 구현

 
 
프로젝트 수요로 인해 QQ 캡처를 모방하는 기능을 썼는데 QQ가 그렇게 잘하지 못했다. 캡처는 주로 서버에 저장된 것이지 그렇지 않았다
프론트 데스크에서 전시하고 전시가 필요할 때 서버에서 찾으면 됩니다.완벽해야 한다.
1. 페이지의 호출

// ，  （ ， ）
function  screenCapture(){
	    var params="method=screenCapture";
		var url = "<%=basePath%>/NameCheck.do";
	    $.post(url,params,function(megs){
	    		$("#screen").val(megs);
	    });
}
