ajax-传数组给后台

前端之家收集整理的这篇文章主要介绍了ajax-传数组给后台前端之家小编觉得挺不错的,现在分享给大家,也给大家做个参考。
var ids = [1,2,3,4];
$.ajax({
 type: "POST",url: "${base}/xxx/xx?ids=" + ids,async: false,dataType: "json",success: function (data) {
  if (data.data) {
      alert(data.data); //ids;
  }
 }
}); 


//后台controller-springMVC
 @RequestMapping("/delete")
 @ResponseBody
  public ResponseEntity<JsonResult> xx(Long[] ids) { 
    System.out.pringln(Arrays.toString(ids));//[1,4,5]
    return ControllerHelper.returnJSONResult(true,"成功",ids);
}
