javascript - MongoDB - Can't read data from the database -


hi newbie , facing issue.i doing rideshare cab application , getting cannot read property 'length' of undefined error in jade file.

my jade file follows:-

html   body     h1 passengers list     each user in users       script(type='text/javascript').         function checkboxlimit(checkgroup, limit){         var checkgroup=checkgroup         var limit=limit         (var i=0; i<checkgroup.length; i++){         checkgroup[i].onclick=function(){         var checkedcount=0         (var i=0; i<checkgroup.length; i++)         checkedcount+=(checkgroup[i].checked)? 1 : 0         if (checkedcount>limit){         this.checked=false         }         }         }         }       p select passenger below:       form#world(name='man')         input(type='checkbox', name='dude')         |  li {passenger.name}         br       script(type='text/javascript').         //syntax: checkboxlimit(checkbox_reference, limit)         checkboxlimit(document.forms.man.dude, 4)

in file trying display users , let driver select 4 passengers..

once done create new jade file display driver , passenger associated driver

the following serverjs snippet:-

app.post('/passenger',function(req,res){         var user = new user({profile:{name:req.body.uname},         type:"passenger",         phone_no:req.body.contact,         origin:{city:req.body.pick},         destination:{city:req.body.drop}       //  email:req.body.email,     //    password:req.body.password     })          user.save();        //  passengers.push(user)        //  console.log(passengers)          res.render('checkbox', {user: user});        // res.redirect('/checkbox')     });     app.get('/checkbox',function(req,res){         res.render('checkbox');     });

my model follows:-

var userschema = new mongoose.schema({   email: { type: string, unique: true, lowercase: true },   password: string,   facebook: string,   google: string,   origin: {city: string, state: string},   destination: {city: string, state: string},   price: array,   time: date,   phone_no: string,   accepted:string,   tokens: array,   type: string,   profile: {     name: { type: string, default: '' },     gender: { type: string, default: '' },     location: { type: string, default: '' },     website: { type: string, default: '' },     picture: { type: string, default: '' }   },    resetpasswordtoken: string,   resetpasswordexpires: date });

i cant seem understand wrong in code..please me out

thanks

var x = {}; x.someproperty; //this undefined x.someproperty.length; // cannot read property 'length' of undefined

so, trying property of undefined. try find in part of code trying length.

function checkboxlimit(checkgroup, limit) { pay attention line, checkgroup undefined.

and var checkgroup=checkgroup, var limit=limit pointless.

=)
