我正在研究 Marionette.behavior。我试图在 View 初始化时动态传递行为哈希，但它没有被分配给 View 的行为对象。因为行为在 View 构建时被初始化。
所以我们通过以下方式实现了解决方案，但这是实现它的正确方法吗？
有没有其他方法可以实现？和
为什么行为不允许动态传递？
这是代码:
var Behaviour = new Marionette.Application();
Behaviour.addRegions({
mainRegion:"#main-region"
});
var Person = Backbone.Model.extend({
defaults:{
firstName:"NA",
lastName:"NA",
phoneNumber:"NA",
presentAddr:"NA",
permanantAddr:"NA"
}
});
var buttonView=Marionette.ItemView.extend({
template:"#buttontemplate",
constructor:function(options){
this.behaviors = options.behaviors;
Marionette.ItemView.apply(this, arguments);
},
events:{
"click .display":"displayDetail"
},
displayDetail:function(){
this.triggerMethod("DisplayPersonDetails");
},
//behaviors:{Behavior1:{ },Behavior2:{ }}
})
var PersonDetailsView = Marionette.ItemView.extend({
template:"#static-template",
ui: {
"Change": ".change"
},
events:{
"click @ui.Change":"changeBehavior"
},
changeBehavior:function(){
},
});
var Behavior1 = Marionette.Behavior.extend({
onDisplayPersonDetails:function(){
var person=new Person({firstName:"abhijeet",lastName:"avhad",phoneNumber:"9604074690",permanantAddr:"sangamner",presentAddr:""})
var myView = new PersonDetailsView({model:person});
Behaviour.mainRegion.show(myView);
}
});
var Behavior2 = Marionette.Behavior.extend({
onDisplayPersonDetails:function(){
var person =new Person({firstName:"abhijeet",lastName:"avhad",phoneNumber:"9604074690",permanantAddr:"",presentAddr:"shivajinagar"})
var myView =new PersonDetailsView({model:person});
Behaviour.mainRegion.show(myView);
}
});
Behaviour.on("initialize:after", function(){
console.log(" started!");
Marionette.Behaviors.behaviorsLookup = function() {
return window.Behaviors;
};
window.Behaviors = {};
window.Behaviors.Behavior1 = Behavior1;
window.Behaviors.Behavior2 = Behavior2;
var buttonview=new buttonView({behaviors:{Behavior1:{ },Behavior2:{}}});
Behaviour.mainRegion.show(buttonview);
});
Behaviour.start();
最佳答案
实现这一点的另一种方法是在您的定义中声明一个函数，该函数返回初始化时提供的行为，如下所示:
var buttonView=Marionette.ItemView.extend({
...
behaviors: function () {
return this.options.behaviors;
},
...
