java - 如何将模型解析为 ajax post 调用

Question

我正在尝试使用 model.addAttribute("myModel",mymodelvariable); 解析我用 spring 加载的模型到 ajax 调用(该模型正在表单中使用)。

这是我使用@Html尝试的内容:

$('#sampleForm').submit(

    function(event) {
        var data = @Html.Raw(Json.Encode(Model));
        $.ajax({
            url: 'http://localhost:8080/hellohello',
            type : "POST",
            data : data,
            beforeSend: function (xhr) {
                xhr.setRequestHeader(header, token);
            },
            success : function(response) {
               $('#reloading').html(response);
            },
            error : function(err) {
                alert("not working")
                console.log("not working. ERROR: "+JSON.stringify(err));
            }
        });
        return false;
    });

Controller :

 @CrossOrigin(origins = "http://localhost:8080")
 @ResponseBody
 @RequestMapping(value = "/hellohello",method = RequestMethod.POST)
 public ModelAndView step1(@ModelAttribute Mymodelvariable mymodelvariable){

      //do stuff and return model
    }

试试这个可能对你有帮助

$('#sampleForm').submit(

function(event) {

    var data={
        "name":$('#name').val(),
        "age":$('#age').val(),
        "xyz":$('#xyz'+str).val(),
        "xyz":$('#xyz'+str).val(),
        "xyz":$('#xyz'+str).val(),
        "xyz":$('#xyz'+str).val(),
        "xyz":$('#xyz'+str).val(),

       }
  $.ajax({
        url : "././hellohello",
        type : "POST",
        contentType : 'application/json; charset=utf-8',
        data: JSON.stringify(data),
        beforeSend: function (xhr) {
            xhr.setRequestHeader(header, token);
        },
        success : function(response) {
           $('#reloading').html(response);
        },
        error : function(err) {
            alert("not working")
            console.log("not working. ERROR: "+JSON.stringify(err));
        }
    });
    return false;
});

Controller 类:

  @CrossOrigin(origins = "http://localhost:8080")
  @RequestMapping(value = "/hellohello",method = RequestMethod.POST)
   @ResponseBody
    public ModelAndView step1(@RequestBody Modelclass mymodelvariable)throws 
      Exception{

  //do stuff and return model
}
