推荐答案

你可以通过发送一个来自Javascript的MVC动作jQuery ajax请求。

将ShowSimple更改为ActionResult

You can the MVC action from Javascript by sending an jQuery ajax request.
Change ShowSimple as ActionResult

public ActionResult ShowSimple()
{
ReportDocument reportdocument = new ReportDocument();
reportdocument.Load(Server.MapPath("~/") + "crystalreport.rpt");
var data=new {Status="Success"};
retunt JSon(data);
}

function Javascriptfunction()
  {

.getJSON（' / Controller / ShowSimple /'， function （data）{
alert（data）;
}）;
}

.getJSON('/Controller/ShowSimple/', function (data) { alert(data); }); }

function fnNext() {
var frm = document.forms[0];
frm.selecteditem.value = "Next";
Javascriptfunction();
return true;
}

希望这有帮助

Hope this helps

public ActionResult ShowSimple()
{
ReportDocument reportdocument = new ReportDocument();
reportdocument.Load(Server.MapPath("~/") + "crystalreport.rpt");
var data=new {Status="Success"};
retunt JSon(data,JsonRequestBehavior.AllowGet);
}

function fnNext() {
var frm = document.forms[0];
frm.selecteditem.value = "Next";
