I am using Spring MVC , example.jsp file with Javascript.
I have been stuck on this for a long time.
Is it possible to use Javascript to laod new data from DB into HTML tables without refreshing the whole page?
I just don't want my whole page being replaced when new data is loaded into table with some event.
If you want to reload a part of you page using JavaScript, basically AJAX.
This is how you should do it.
Let's assume that you're using jQuery as a JavaScript Framework.
You'll need to use jQuery.ajax() in the Client Side.
var successHandler = function( data, textStatus, jqXHR ) {
// After success reload table with JavaScript
// based on data...
};
var errorHandler = function( jqXHR, textStatus, errorThrown ) {
// Error handler. AJAX request failed.
// 404 or KO from server...
alert('Something bad happened while reloading the table.');
};
var reloadData = function() {
// Process your request
var request = new Object();
request.id = 'some id'; // some data
// Make the AJAX call
jQuery.ajax({
type : 'POST',
url : 'http://domain/context/reload-data-url',
contentType: 'application/json',
data : JSON.stringify(request)
success : successHandler,
error : errorHandler
});
};
Call the reloadData()
function when you need to reload the table.
You're using Spring MVC. Then your Controller should look like:
// Spring MVC Controller
@Controller
public class ReloadDataController {
// Request Mapping
@RequestMapping(value = '/reload-data-url', method = RequestMethod.POST)
@ResponseBody
public ResponseEntity<String> processReloadData(@RequestBody String body) {
// Get your request
JSONObject request = new JSONObject(body);
String id = request.getString("id"); // Here the value is 'some id'
// Get the new data in a JSONObject
JSONObject response = new JSONObject();
// build the response...
// Send the response back to your client
HttpHeaders headers = new HttpHeaders();
headers.add("Content-Type", "application/json; charset=utf-8");
return new ResponseEntity<String>(response.toString(),
headers, HttpStatus.OK);
}
}
You don't have to use JSON but I think this is the best way. Hope this will help you.
