javascript - why does the got view is undefined in construct function? -

why got view undefined in construct function ?

i set in define, set in function arguments, still undefined, view returned object.

here view must got:

       define([ 'jquery', 'backbone', 'resources', 'views/ship', 'models/ship', 'models/stage' ], function ($, backbone, resources, shipview, shipmodel, stagemodel) { var stageview = backbone.view.extend({     tagname: 'canvas',     id: 'stage',     classname: 'stage',     model: stagemodel,     initialize: function () {         this.listento(stagemodel, 'change', this.move);         this.ctx = this.el.getcontext('2d');         resources.load(['images/space1.jpg']);     },     render: function() {         this.el.width = $('body').width();         this.el.height = $('body').height();         this.model.xpos = 1500 - (this.el.width / 2);         this.model.ypos = 1500 - (this.el.height / 2);          return this;     },     move: function (model) {     },     motion: function () {      } }); return new stageview(); }); 

here view must one:

 define([ 'jquery', 'backbone', 'resources', 'views/stage', 'models/ship' ], function ($, backbone, resources, stageview, shipmodel) {  var shipview = backbone.view.extend({     tagname: 'canvas',     id: 'ship',     classname: 'ship',     model: shipmodel,     initialize: function () {         console.log(stageview); //---- undefined          this.ctx = this.el.getcontext('2d');         resources.load(['/images/ship.gif']);         this.el.width = $('body').width();         this.el.height = $('body').height();         this.model.setcenter({             x: this.el.width / 2,             y: this.el.height / 2         });         this.shippos = {             x: this.el.width / 2 - 35,             y: this.el.height / 2 - 35         };         this.inmove = false;         this.loaded = false;     },     events: {         'click': 'move',         'mousemove': 'mousemove'     },     render: function () {         var = this;         resources.onready(function () {             that.loaded = true;             that.image = resources.get('/images/ship.gif');             that.ctx.translate(that.el.width / 2, that.el.height / 2);             that.ctx.drawimage(that.image, -35, -35, 70, 70);         });         return this;     },     move: function (event) {         this.model.setclickcoords({             x: event.pagex,             y: event.pagey         });         this.rotate(event);         this.inmove = true;     },     movedone: function () {         alert("asd")         this.inmove = false;     },     mousemove: function (event) {         if (!(this.inmove) && this.loaded) {          }     },     rotate: function (event) {      } });  return new shipview();  });
