我有一个具有itemView的CompositeView。我正在通过options对象将值传递到实例化的CompositeView中。在compositeView中,我将itemview属性设置为itemview,并且我正在使用itemViewOptions属性来尝试传递传入组合视图中的选项的值。这是我的代码:
CompositeView:
myFirstCompositeView = Marionette.CompositeView.extend({
template: Handlebars.templates["myTemp"],
initialize: function(options){
//this console statement works as expected options are there
console.log("myFirstCompositeView.initialize() -> options -> ", options);
this.eventBus = options.eventBus;
this.mapModel = options.myModel;
//i tried this
this.itemView : myFirstItemView;
this.itemViewOptions = this.myModel;
},
i also tried this...
itemView : myFirstItemView
itemViewOptions = this.myModel;
});
项目视图:
myFirstItemView = SegmentItemView = Marionette.ItemView.extend({
template: Handlebars.templates["myothertemp"],
initialize : function(options){
//value undefined
console.log("myFirstItemView .initialize() -> ", options.myModel);
},
});
CompositeView的实例化:
new myFirstCompositeView ({
myModel : {testval : 777, teststr: "holy cow"},
collection: model.get("myFirstCollection"),
eventBus: eventBus
}));
反正有将值传递给itemView吗?
最佳答案
尝试这个:
myFirstCompositeView = Marionette.CompositeView.extend({
template: Handlebars.templates["myTemp"],
initialize: function(options){
this.eventBus = options.eventBus;
this.mapModel = options.myModel;
},
itemView : myFirstItemView,
itemViewOptions: function(){
return {
myModel: this.myModel
};
}
});
From the Marionette documentation:
如果需要,还可以将itemViewOptions指定为函数。
计算要在运行时返回的值。模型将通过
计算中是否需要访问该函数
itemViewOptions。该函数必须返回一个对象,并且
对象的属性将复制到itemView实例的
选项。
