Question

我有java对象作为对象A包含对象B而对象B包含对象C，这是我的对象如下

public class objectA{
 private String name;
 private String college;
 private objectB obj; 
 }
 public class objectB{
 private String address;
 private String dept;
 private objectC obj; 
 }
 public class objectC{
 private String bus;
 private String bike;

 }

我必须将objectA从 jsp 发送到控制器如何在jquery中创建对象objectA，这是我的ajax代码

$("#SaveBtnId").click(function() {

        **HOW TO MAKE OBJECT A**

        $.ajax({
            url : "../seller/addSeller",
            type : "post",
            data : objectA,
            contentType : "application/json",
            dataType : "json",
            success : function(data) {
                alert("Saved Successfully");
            },
            error : function(error) {
                alert(error);
                alert("Details failed to save");
            }
        });
    });

以下代码为您创建了一个可以传递给控制器的模型。如果您遇到任何问题，请尝试告诉我。

$("#SaveBtnId").click(function() {

ObjectC:{
bus:$('#txtBus').val(), //Considering as getting from textBox
dept:$('#txtBike').val(),
};

ObjectB:{
address:$('#txtAdd').val(), //Considering as getting from textBox
dept:$('#dept').val(),
obj:ObjectC
};

ObjectA:{
name: $('#txtName').val(),
college: $('#txtCollege').val(),
obj:ObjectB
};
        $.ajax({
            url : "../seller/addSeller",
            type : "post",
            data : JSON.stringify(objectA),
            contentType : "application/json",
            dataType : "json",
            success : function(data) {
                alert("Saved Successfully");
            },
            error : function(error) {
                alert(error);
                alert("Details failed to save");
            }
        });
    });

你可以这样做：

$("#SaveBtnId").click(function() {

   var a = {};
   var b = {};
   var c = {};
   c['bus'] = 'bus';
   c['bike'] = 'bike';

   b['address'] = 'address';
   b['dept'] = 'dept'
   b['objectC'] = c;

   a['name'] = 'name';
   a['college'] = 'college';
   a['objectB'] = b;



    $.ajax({
        url : "../seller/addSeller",
        type : "post",
        data : JSON.strigify(a),
        contentType : "application/json",
        dataType : "json",
        success : function(data) {
            alert("Saved Successfully");
        },
        error : function(error) {
            alert(error);
            alert("Details failed to save");
        }
    });
});

这可能会有所帮助。请注意，所有三个类都必须具有setter和getter。
