在EmberJS中重新绑定时，数组值没有得到反映 [英] Array values are not getting reflected while rebinding in EmberJS
问题描述
我有一个数组（ ['Name1'，'Name2'，'Name3'] ），我正在加载页面。
现在按钮点击，我想为该数组分配一些其他值，并像
应用程序一样填充。 myArray = ['Name4'，'Name5'，'Name6']
但是没有反映出来。

var App = Ember.Application.create（）
App.myArray = ['Name1'，'Name2'，'Name3']
App.IndexRoute = Ember.Route.extend（{
actions：{
ClickFn：function（）{
App.myArray = ['Name4' 'Name5'，'Name6']
console.log（App.myArray）;
}
}
}）;
< / script>
< / body>
< / html>
目前的情况是
使用 Ember.set 方法进行更改以在模板中反映。所以只需将 App.myArray = ['Name4'，'Name5'，'Name6'] 替换为
<$ Ember.set（App，'myArray'，['Name4'，'Name5'，'Name6']）;
我不会对这种东西使用全局变量。您可以在IndexRoute本身介绍它（我想你正在做它的测试目的）。
I have an array (['Name1','Name2','Name3']) which I am populating at page Load.
Now at button click, I want to assign some other values to that array and populate the same like
App.myArray = ['Name4','Name5','Name6']
But it is not reflected.

App.myArray = ['Name1','Name2','Name3']

App.myArray = ['Name4','Name5','Name6']
console.log(App.myArray) ;
}
}
});
</script>
</body>

The current situation is
I am looking for the output should be when button click
Use Ember.set method for changes to reflect it in template. so just replace App.myArray = ['Name4', 'Name5', 'Name6'] with the below
Ember.set(App,'myArray',['Name4', 'Name5', 'Name6']);
I would say dont use global variable for this kind of stuff. you can introduce it in IndexRoute itself.(i guess you are doing it for testing purpose).
