How can I pass jquery variable as parameter to Java controller by href?

This is my variable in javascript:

var dataid = dataInfo[i];

I want to pass the variable to my java controller through href:

 row = row + "<tr><td>" + dataid + "</td><td>" +
       schoolid + "</td><td>" + 
      "<td><a class='details' id='" + dataid + "'  href='@{DataManagement.dataDetails(dataId)}'>Details</a></td>"+
        "<td>"+
        </tr>";

but controller gets null value.

I am trying this using ajax:

        $.ajax({
            type: "GET",
            url:  "@{DataManagement.dataDetails}",
            data: {
                id: dataId
            },
            success: function(data) {
                console.log(data);

            }


        });

This is my controller:

public static void dataDetails(Long id) throws SQLException {

        Logger.info("id: "+ id);

        //dataId=dataId.trim();

        //Long iid = Long.parseLong(dataId);
        Data data = Data.findById(id);


        String totalStudent = Data.getTotalStudent(1L);

        Logger.info("totalStudent: " + totalStudent);

        renderArgs.put("totalStudent",totalStudent);

        render(data,totalStudent);

    }

But after ajax call it is not render the new page.

How can I do this?

It works!!!

I changed it to :

<td><a class='details' id='" + dataid + "'  href='/datamanagement/dataDetails/"+dataid+"'>Details</a></td>

You can send a json request with ajax and accept it on Controller.

Ajax Request:

$.ajax({
    type: "POST",
    contentType: "application/json",
    data: JSON.stringify(yourObject),
    url: "/path",
    success: function (msg) {
        console.log(msg);
        window.location = "/redirectTo";
    },
    error : function(e) {
        console.log('Error: ' + e);
    }

});

On Controller:

@ResponseBody
@CrossOrigin @RequestMapping(value = "/path", method = RequestMethod.POST, consumes=MediaType.APPLICATION_JSON_VALUE)
private ResponseEntity<YourObject> someMethod(@RequestBody YourObject obj){
        // do your coding here
        return new ResponseEntity<YourObject>(modifiedObject, HttpStatus.OK);
    } catch (Exception e) {
        return new ResponseEntity<YourObject>(HttpStatus.BAD_REQUEST);
    }
}
