After posting data from the Jquery $.post()
method, I am attempting to return some data which I want to use in the Jquery alert() from a Spring boot 1.5.1 controller method. Currently, the returned data is empty when used in the alert().
Jquery:
$('#element').click(function() {
var formData = $('#element').serialize();
var posting = $.post( '/update.json?id=${item.id}', formData );
posting.done(function( data ) {
alert(data);
});
return false;
});
Controller:
@RequestMapping("/update.json")
@ResponseBody
public void update(HttpServletRequest request,
Map model,
@RequestParam(value="id", required=true) Integer id) {
// to validation and binding...
model.put("result", "test");
}
Why is the result property not accessible in the Jquery data
object in the callback?
Your Controller has a return type as void, that's normal. You can either use a response entity, if you want to set the status:
return new ResponseEntity<String>("test", HttpStatus.OK)
or you can return a plain string a well.
