如何在emberjs上的textarea上收听粘贴事件 [英] How to listen to a paste event on a textarea in emberjs

问题描述

我有一个包含以下模板的组件：

I have a component that holds a with the following template:

<div>
  {{textarea value=content autofocus="autofocus"}}
  <button {{action 'cancel'}}>cancel</button>
</div>

如何收听粘贴事件在我的组件中的这个textarea上？

How can I listen to a paste event on this textarea in my component?

我试图倾听粘贴操作，但这似乎不起作用：

I tried to listen on the paste action but this dont seems to work:

App.EditableTextComponent = Ember.Component.extend({

  templateName: 'components/editable-text',

  actions: {
    paste: function() {
      console.log(arguments);
    }
  }

});

推荐答案

As @ wojciech-bednarski在他的评论中建议已将自定义事件侦听器添加到我的应用程序中：

As @wojciech-bednarski suggest in his comment, I have added the custom event listener to my app:

var App = Ember.Application.create({
  customEvents: {
    paste: "paste"
  }
});

，然后可以在我的组件中收听

and could then listen to it in my component

App.EditableTextComponent = Ember.Component.extend({

  paste: function(event) {
    console.log(event)
  }

});
