Javascript 如何通过href将jquery变量作为参数传递给Java控制器？

这是我的javascript变量：

var dataid = dataInfo[i];

我想通过href将变量传递给我的java控制器：

 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>";

这是我的控制器：

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);

    }

@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);
    }
}

但是在ajax调用之后，它不会呈现新页面

我该怎么做呢？

您可以使用ajax发送json请求，并在控制器上接受它

Ajax请求：

$.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);
    }

});

在控制器上：

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);

    }

@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);
    }
}

@ResponseBody
@CrossOrigin@RequestMapping（value=“/path”，method=RequestMethod.POST，consumes=MediaType.APPLICATION\u JSON\u value）
私有ResponseEntity someMethod（@RequestBody YourObject obj）{
//你在这里编码吗
返回新的ResponseEntity（modifiedObject，HttpStatus.OK）；
}捕获（例外e）{
返回新的响应属性（HttpStatus.BAD_请求）；
}
}

它可以工作

我把它改成：

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

你不能，java在服务器端执行，js在客户端。你不能将js变量作为参数传递给java函数。你是在使用模板引擎在服务器端对代码进行预处理吗？因为js不能访问java代码，那么我该怎么办呢？你可能想看看AJAX。
