问题描述
ajax.js代码: url正确,已经进入到对应的aciton并执行有结果,但是 xmlHttp.onreadyStatechange=function() 这句一直未执行,我在函数里写了alert并未跳出,请大神看看娜丽有问题~~ action的代码: public ActionForward execute(ActionMapping mapping, ActionForm form,HttpServletRequest request, HttpServletResponse response) throws JSONException {ManagerForm managerForm = (ManagerForm) form;// TODO Auto-generated method stub List signList=null; SignInService signService=(SignInService)getBean("signInService");signList=signService.findAll(signIn);JSONObject result = new JSONObject();result.put("signlist", signList);request.setAttribute("ajaxResult", result);return null;} jsp的代码:<body><input type="button" value="查询" onclick="getSignList()" /></body>
解决方案
xmlHttp.onreadyStatechange 改为 xmlHttp.onreadystatechange 试试
