ajax与jquery批量更新，异步请求

js：

<script type="text/javascript"> $("a[id=submit]").click(function(){ var obj = {}; $("tr",navTab.getCurrentPanel()).each(function(){ var id = $("input[name=id]",this).val(); var type = $("select[name=expiryStatus]",this).val(); obj[id]=type; }); var date={list:JSON.stringify(obj)}; var url="serviceFailureEquipmentsAction_updateType.action"; $.post(url,date,function(date){ DWZ.ajaxDone(date); if (date.statusCode == DWZ.statusCode.ok){ alertMsg.correct(date.message); }else{ alertMsg.error(date.message); } },"json"); }); </script>

action：

public String updateType(){ String list=ServletActionContext.getRequest().getParameter("list"); //JSONArray json = JSONArray.fromObject(list); JSONObject object=JSONObject.fromObject(list); Set<String> keys=object.keySet();{ for(String key:keys){ String value=object.getString(key); serviceFailureEquipmentsService.update(Integer.parseInt(key), Integer.parseInt(value)); } } getobject("200", "质保修改成功", null, null, "sucess", null); return null; }
