从node.js发送响应到Jquery

Question

Iam new to node.js I want to get data fetch from db and send that returned value to Jquery. in the following code

exports.signin = function (signupCollection, context) {
var record = utils.httpBody(context.req);
signupCollection.find({ },{email: record.email,password: record.password},function(err, result) {
      console.log("result-------"+result) // prints the data correctly
      if(!err) return result;
    });    
}

result prints the correct data i want...it is getting properly

In jquery

var data = {   
    "email": $('#email').val(),
    "password": $('#password').val()   
   };
        $.ajax({
            type: "post",
            url: "/signIn",
            dataType: "json",
            data: data,
            success: function (data) {
                console.log("sign in succesfully!!"); // here i want to  getthe result data
                console.log("SIGN IN RESPOSEE----"+data);             

            }
        });

inside this i couldn't get the resultant data returned from node,js

success: function (data) {
alert("data-------------"+data);
}

You should have written the result to http.ServerResponse ( response object) and call response.end() .

Are you using any web framework? My guess is context.res would be the response object.

Use:

return context.res.end(JSON.stringify(result));

instead of

return result;
