Question

我正在使用带有jqgrid的spring 3一切正常工作，除了从控制器加载数据到select选项我尝试加载到jsion Array对象并发送到jsp页面但是我无法加载值来选择选项使用

(editoptions: {dataUrl:"location/role.do")

请查看我的代码并帮助我

我的控制器类

@Controller
@RequestMapping("/location")
public class AddCenterLocation {

    @Autowired
    private RecoupService recoupService;

    @RequestMapping(method = RequestMethod.GET)
    public @ResponseBody
    CustomCenterLocationResponse getAll() {
        List<? extends CenterLocation> users = recoupService.getCenter();
        response.setRows(users);
        response.setRecords(String.valueOf(users.size()));
        response.setPage("1");
        response.setTotal("10");
        return response;
    }

    @RequestMapping(value = "/role", method = RequestMethod.GET)
    public @ResponseBody
    CustomGenericResponse role(HttpServletRequest request, HttpServletResponse response) {
        JSONObject jsonArray = new JSONObject();
        try {
            List<CenterLocation> users = recoupService.getCenter();
            for (CenterLocation harbour : users) {
                jsonArray.put(harbour.getCenterId(), harbour.getCenterAddress());
            }
            response.getWriter().write(jsonArray.toString());
        } catch (Exception exception) {
            System.out.println("error is " + exception);
        }
        return null;

    }

这是我的jsp页面

jq(function() {
    jq("#grid").jqGrid({
        url:'location.do',
        datatype: 'json',
        mtype: 'GET',

首先将jackson lib导入lib文件夹，以便将json数据发送到jsp页面。然后创建两个pojo类，这仅用于演示，您可以根据需要进行更改

公共课位置{

列出角色;

 //setter getter

}

公共类角色 {

private String id;
private String name;

// setter getter

}

这是控制器请求

@RequestMapping（value =“/ role”，method = RequestMethod.GET）

public @ResponseBody
Location role(HttpServletResponse response) {

    System.out.println("name");
    Location shop = new Location();
    List<Role> list = new ArrayList<Role>();
    Role role = new Role();
    role.setId("abc");
    role.setName("abc");
    list.add(role);
    Role role1 = new Role();
    role1.setId("abc1");
    role1.setName("abc1");
    list.add(role1);
    shop.setRole(list);
    return shop;

}

jsp页面

修改jqgrid的选择部分

{ name: 'name', index: 'name', editable: true, edittype: "select",
 editoptions: {dataUrl:"location/role.do", 
buildSelect: function (role) 
{ 
var data = jQuery.parseJSON(role); 
var s = '<select>'; 
for (var i = 0; i < data.role.length; i++) {
 s += '<option value="' + data.role[i].id + '">' + data.role[i].name + '</option>'; 
} 
return s + "</select>"; 
} 
} 
}

它会运行良好

弹簧3与jqgrid，我试图从控制器加载数据到选择选项，无法填充
