在我的主干功能中,虽然名称得到更改,但更改功能根本没有触发..任何人都建议我获取它的正确方法..(实际上我需要更改内容并需要更新);
代码 :
(function($){
var list = {};
list.model = Backbone.Model.extend({
defaults:{
name:'need the name'
},
initialize:function(){
this.bind('change:name', function(model) {
console.log('Model->change()', model);
});
}
});
list.collect = Backbone.Collection.extend({
model:list.model,
url : 'data/names.json',
initialize:function(){
this.fetch({update:true});
this.keepUpdate();
},
keepUpdate:function(){
var that = this;
var updateData = function(){
that.fetch({update:true});
myTimeout = setTimeout(updateData,10000);
}
var myTimeout = setTimeout(updateData,10000);
}
});
list.view = Backbone.View.extend({
initialize:function(){
this.collection = new list.collect();
this.collection.on("update", this.render, this);
this.collection.bind("change:name", function(model, attributes){
console.log(model,attributes,'property changed'); // this is not triggering at all..
});
},
render:function(data){
_.each(this.collection.models, function(data){
//console.log(data.get('name')); it works fine
})
},
updateName:function(){
console.log('updated called');
}
});
var newView = new list.view();
})(jQuery)
