arrays - Mongodb query doesn't work -

-

in image sharing application can upload images , create albums. when delete image site shall deleted in albums (the ones has got image in it).

below route deleting image, , need why code deleting images (imagename , imageid) in albums below doesn't work.

thanks in advance!

the models:

var albumschema = new schema({       title             : string,       imagename         : [string],       imageid           : [string] });  modelobject.albumschema = albumschema; modelobject.album = mongoose.model('album', albumschema);

-

var blogpostschema = new schema({     name : string,     size : number,     type : string,     author : objectid,     title   : string });  modelobject.comment = mongoose.model('comment', commentschema); modelobject.blogpost = mongoose.model('blogpost', blogpostschema);

the part doesn't work in code below following:

albums[i].imagename.remove(j); albums[i].imageid.remove(j);                             albums[i].save(function (err){     if (err) {         console.log(err);         //     } });

full code:

 app.get('/blog/delete/:id', function(req, res){      model.blogpost.findbyid(req.params.id, function (err, blog){          var theimage = blog.name;          var query = albummodel.album.find( { imagename:theimage } )         query.exec(function (err, albums) {              if (!albums) {                  blog.remove(function(err) {                     console.log(err);                     //                 });                  res.redirect('/blogs');              }              else {                 (var = 0; < albums.length; i++) {                     (var j = 0; j< albums[i].imagename.length; j++){                          if (theimage == albums[i].imagename[j]){                              albums[i].imagename.remove(j);                             albums[i].imageid.remove(j);                                                         albums[i].save(function (err){                                 if (err) {                                     console.log(err);                                     //                                 }                             });                         }                     }                 }             }              blog.remove(function(err) {                 console.log(err);                 //             });              res.redirect('/blogs');         });     }); });

javascript arrays don't have remove method expect code may crashing. should using code albums[i].imagename.splice(j, 1); instead.
