    $.getJSON(url_country, function(data) {
      $.each(data,function(key,val){

尝试一下，希望对您有帮助

var url_country="<?=base_url()?>country.json";
var user_define_country = 'USA';
var negara_list ="<option value=''></option>";
    $.getJSON(url_country, function(data) {
      $.each(data,function(key,val){
         if(user_define_country == val){
            negara_list += "<option value="+val+" selected='selected'>"+val+"</option>";
         }else{
            negara_list += "<option value="+val+">"+val+"</option>";
         }
      });
      $(".negara").html(negara_list);
  });

您可以尝试类似的操作，如果您的json响应仅是一个国家/地区，则无需播放@Slf4j @CrossOrigin(origins = "*") @RestController public class ComplainsController { @CrossOrigin(origins = "*") @RequestMapping(value = "/aalcomplaint/api/complaint/lodge-complaint", method = {RequestMethod.GET, RequestMethod.POST}) public ModelAndView lodgeComplaint(final HttpServletRequest request, ModelAndView modelAndView, final RedirectAttributes redirectAttributes) { modelAndView.addObject("policyNumber","12345"); modelAndView.setViewName("redirect:/list-complains"); return modelAndView; } }函数，如果您的响应不只一个国家/地区，则可以指定将哪个国家/地区设为默认国家/地区< / p>

针对单个国家/地区的答复

each

用于与多个国家/地区进行回复

    var url_country="<?=base_url()?>country.json";
    var negara_list ="<option value=''></option>";

    negara_list += "<option value="+url_country.country+" selected>"+url_country.country+"</option>";

       $(".negara").html(negara_list);
    });

从json设置选择选项
