oop - Unexpected identifier in Javascript Object -

i creating following object:

  var iobreadcrumb = {     breadcrumbs: []      add: function(title, url){       var crumb = {title, url};       this.breadcrumbs.push(crumb);     }   }; 

i getting unexpected identifier error. not sure coming from, in block of code.

you need comma between members of object, cause of error cite. need put colon, rather comma, between key-value pair in crumb object.

var iobreadcrumb = {   breadcrumbs: [], // <-- comma here    add: function(title, url){     var crumb = {title: url}; // <-- colon here     this.breadcrumbs.push(crumb);   } }; 

if want object there 2 members, 1 title , 1 url, may want this:

var crumb = {   title: title,   url: url }; 

i don't know whether work breadcrumbs setup...
