Javaweb Local Refresh-ajax asynchronous request SPRINGMVC display the returned JSP content instead of the IFRAME

To introduce jquery on the JSP

<script src="<%=request.getcontextpath ()%>/js/jquery_ui/jquery.js"></ Script>

Initiating a request in JS

functionGet(p) {varPatch="Show"+p; $.ajax ({//This is the $.ajax () methodType"POST", Url:patch,//The path can be in relative path, and the starting point is the path shown in the JSP where this method residesData: $ ('#myform'). Serialize (),//Ajax Submission FormDataType:"HTML",//The data type that accepts the response, my response is a page, so here's the "HTML"success:function (data) {$ ('#mydiv'). HTML (data);//I put the response page in a div to show                                    }            })        }

MyForm is a form tag in the JSP Id,mydiv is a div id,ajax to display the location of the JSP in the middle of this div, remember to add these two in the JSP

<form id="myform" method="post" >                <input id= " Hidden " name="ID" type="hidden" Value=${id} >            </form><div  id="mydiv">                            </div>

MyForm normally initiates a SPRINGMVC request, controller returns to a JSP normally

I did not do the following step, but the normal display.

Add @ResponseBody comment to the Controller's method of accepting paths

@ResponseBody// function is to send the returned object as a response to the page      "/showaj"  )          Public string Toindex (string ID, model model)        {              return"AJ";        }
