Javascript Ajax在节点js中返回未定义的响应？
我正在尝试将ajax请求发布到节点js中的server.js脚本。然后，脚本将数据从ajax请求传递到存储过程，并将结果返回给ajax函数。但由于某些原因，在调试ajax函数时，我遇到了一个未定义的错误。我可能做错了什么 plain.ejsJavascript Ajax在节点js中返回未定义的响应？,javascript,jquery,ajax,node.js,Javascript,Jquery,Ajax,Node.js,我正在尝试将ajax请求发布到节点js中的server.js脚本。然后，脚本将数据从ajax请求传递到存储过程，并将结果返回给ajax函数。但由于某些原因，在调试ajax函数时，我遇到了一个未定义的错误。我可能做错了什么 plain.ejs <html> <head> <script src="http://code.jquery.com/jquery-1.11.3.min.js" ></script> <script sr

通过指定
数据类型：“json”res.render("plain.ejs",{Resultset:resultset});
res.json({ Resultset : resultset });
此错误发生在哪一行？@C0dekid:-error:function（Result）{console.log（Result.d）；//它一直转到error//function}尝试在错误处理程序中记录
ResultResult.dd结果console.log（“result:，result）res.json({ Resultset : resultset });
