第一种getJSON方式：

前台调用：

    	function showElement(element,id){　　　　　　 $.getJSON("/portal/edu/updateEdu?id="+id+"&item="+element.id+"&value="+element.value,function(data){		if("success"==data.result){			window.location.reload();		 }		else{ 			alert("Update Error!");		}	  });}

 

后台处理

@RequestMapping("/updateEdu")	public String updateEdu(Long id,String item,String value,HttpServletResponse response){		//String result = "{\"result\":\"success\"}";		eduService.updateById(id,item,value);				JSONObject data = new JSONObject();		try {			data.put("result", "success");		} catch (Exception e) {			System.out.println(e.getMessage());		}						PrintWriter out = null;		response.setCharacterEncoding("UTF-8");		response.setContentType("text/html; charset=UTF-8"); 	    try {	    	out=response.getWriter();	        out.write(data.toString());	        return null;	    } catch (IOException e) {	        e.printStackTrace();	    }	    out.flush();		out.close();			return "redirect:/edu/getEduList";	}

 

 

另一种get方式

前台调用

    function del(id){			  		if(confirm("Are you sure to delete this item?")){			$.get("/portal/edu/delEdu?id="+id,function(data){			　　if("success"==data.result){					alert("Delete Done!");					window.location.reload();			　　}			　　else{				    alert("Error!");			　　}		});}else{	return; } }

 

后台处理i

@RequestMapping("/delEdu")	public void delEdu(Long id,HttpServletResponse response){		String result2 = "{\"result\":\"success\"}";		eduService.delete(id);		PrintWriter out = null;	    response.setContentType("application/json");	    try {	    	out=response.getWriter();	        out.write(result2);	    } catch (IOException e) {	        e.printStackTrace();	    }	   	}
