ajax跨域實例

以下爲S2。
跟普通的地方不同的是要回調

dataType : "jsonp",
jsonp : "callBack",
jsonpCallback : "success_back",

callBack需寫getter setter.

function getTeacher(id) {
	try{
		$.ajax({
				url : "http://b.com/res/test!getName.action",
				type : "get",
				data : {
					"id" : id
				},
				async: true,
				dataType : "jsonp",
				jsonp : "callBack",
				jsonpCallback : "success_back",
				success : function(result) {
					alert(result[0].name);


				},
				error : function(error) {
				}
			});
		}catch(err){
		}
	}

public String getTeacherByPointId() {
		try {
				String result = callBack;
				HttpServletResponse response = this.getServletResponse();
				String tName = teacherService.getTeacherById(videoPointId);
				response.setContentType("text/plain");
				response.setCharacterEncoding("utf-8");
				response.getWriter().write(result+"([{'name':'"+tName+"'}])");
		} catch (Exception e) {
			logger.error("error",e);
		}
		return null;
	}
