                               .addClass("ui-state-disabled")
                               .closest("LoginId")
                               .prev(".CaptionTD")
                               .prop("disabled", true)
                               .addClass("ui-state-disabled");
                       ,

                   ,
             recreateForm: true 
                   );
        
    );
);

来自 api 的下拉数据如下：

["RoleId":1,"RoleName":"Administrator","RoleId":2,"RoleName":"Sales","RoleId":3,"RoleName":"Secretory/President","RoleId":4,"RoleName":"Apartment Owner","RoleId":5,"RoleName":"Apartment User"]

【问题讨论】：

这可能会对你有所帮助，***.com/questions/13116256/…

它不工作请帮助我

【参考方案1】：

这样使用：

    editoptions:value: getData()

然后创建一个方法

    function getData()
     var states = ["RoleId":1,"RoleName":"Administrator","RoleId":2,"RoleName":"Sales","RoleId":3,"RoleName":"Secretory/President","RoleId":4,"RoleName":"Apartment Owner","RoleId":5,"RoleName":"Apartment User"];        
      return states;

    

在您的情况下，您需要在 getData() 中添加 ajax 调用并返回结果创建的值/数组。
