Read data for the view

We read the data from Controller to the view. In this tutorial we are going to check the view code and controller code.

To load list in view

There is a JavaScript code in a view to load data from controller to render in a HTML view.

load = function(){ 
        $.ajax({
            url:'list',
            type:'POST',
            success: function(response){
                    data = response.data;
                    $('.tr').remove();
                    for(i=0; i<response.data.length; i++){                  
                        $("#table").append("<tr class='tr'> <td> "+response.data[i].user_name+" </td> <td> "+response.data[i].email+" </td> <td> <a href='#' onclick= edit("+i+");> Edit </a>  </td> </td> <td> <a href='#' onclick='delete_("+response.data[i].user_id+");'> Delete </a>  </td> </tr>");
                    }          
            }              
        });
         
    }

There is a Java code in controller to fetch record from database to JavaScript code.

 @RequestMapping(value = "/list", method = RequestMethod.POST)
    public @ResponseBody Map<String, Object> getAll(Users users) {
        Map<String, Object> map = new HashMap<String, Object>();
 
        List<Users> list = userServices.list();
 
        if (list != null) {
            map.put("status", "200");
            map.put("message", "Data found");
            map.put("data", list);
        } else {
            map.put("status", "404");
            map.put("message", "Data not found");
 
        }
 
        return map;
    }
