javascript - How to get POSTed (jquery) array data in Node.js (using express) -

i trying post array server. have difficulties in doing properly.

the array trying post, array of objects dynamically structured, don't know it's length.

to more precise, array of form.

var names =[{id:1, name:"nick"},{id:2,name:"bob"},{id:3,name:"john"}.....{id:n, name:"whatever"}]

i posting using jquery:

$.post("save_names", {         'names[]': names     }, function(results) {         alert(results);     });

my node code, following: (i use stormpath-express)

app.post('/save_names', config.access_group, function(req, res) {     console.log("body ", req.body); });

this way getting following console.log

body  { 'names[]': [ '[object object]', '[object object]', '[object object]' ] }

when try print array : console.log("body ", req.body.names); body undefined

can explain why happening? how solve error, , why can't post names:names , work?

you're sending data incorrectly. can examine request in development tools. you'll see this:

form data     names[]:[object object]     names[]:[object object]     names[]:[object object]     names[]:[object object]

try converting data json yourself:

$.post("save_names", {         'names[]': json.stringify(names)     }, function(results) {         alert(results);     });

don't forget correctly access array: console.log("body ", req.body['names[]']);.
