ビューで blockView のインスタンスを作成し、モデルをパラメーターとして渡します。しかし、実行すると、「TypeError:未定義をオブジェクトに変換できません」というエラーが表示されます。このエラーを追跡しようとしましたが、取得できません。誰でもどうぞ。以下のコードを見つけてください
var DCSSPACE = DCSSPACE || {};
$(document).ready(function(){
WorkSpace = new draw2d.Workflow( "canvasdiv" );
collection = new DCSSPACE.collection.collection();
view = new DCSSPACE.view.view({WorkSpace : WorkSpace, collection : collection});
});
DCSSPACE.view = function(){
var uniqueid = 1, blockCounter = 0;
var view = Backbone.View.extend({
el : $("#canvasdiv"),
views : {},
initialize : function() {
console.log("View");
this.collection.bind("add", function(m, temp, data){
console.log(data.evt);
//Here i am getting error "TypeError: can't convert undefined to object"
this.views[m.cid] = new blockView({data : data, model : m, id : "view_" + m.cid});
},this);
this.collection.bind("remove", function(m){
this.views[m.cid].remove();
delete this.views[m.cid];
}, this);
this.render(WorkSpace);
},
render : function(WorkSpace) {
$("#sidediv").accordion();
this.disableSelection(document.body);
var menu = new draw2d.FlowMenu(WorkSpace);
WorkSpace.addSelectionListener(menu);
var toolwindow = new draw2d.Toolbox();
WorkSpace.setToolWindow(toolwindow);
toolwindow.setPosition(0,0);
$(".btn").draggable({
helper : "clone",
stop : function(event, ui) {
var data = {
id : this.id,
evt : event.originalEvent,
};
if(event.originalEvent.pageX >= 220) {
var m = new DCSSPACE.model.FunctionBlockModel();
collection.add(m, data);
}
}
});
return this;
},
/* Function for deselect body contents */
disableSelection : function(target) {
if( typeof target.onselectstart != "undefined")//IE
target.onselectstart = function() {
return false;
}

target.style.MozUserSelect = "none"
else//All other
target.onmousedown = function() {
return false
}
target.style.cursor = "default"
}
});
var blockView = Backbone.View.extend({
initialize : function(formalObj){
console.log("block view");
$("#canvasdiv").mousemove(this, this.mousemove).mouseup(this, this.mouseup);
this.model.set({id : formalObj.data.id});

});
return{

blockView : blockView
}
}();
