                obj.Ename = name;
                $('#down').append(obj.Ename);

                $('#down').append(obj.Ecode);
                $('#down').append("<br>");
            }
        }
    });
});

这是我的jQuery代码，我尝试从JSON对象创建表单元素。现在的问题是我没有办法在Ecode的标签中附加Eprops的属性

Answer 1

您可以使用<语法在jQuery中创建元素：jQuery( html [, ownerDocument ] )

此语法的第二个参数可以是对象属性名称/值：

Jstr.JSON.forEach(function (elem) {
    $(elem.Ecode, elem.Eprops).appendTo("body");
});

如何使用JSON和JQuery在标记中插入元素
