我正在使用Ember 2.9,并希望使用“粘贴”事件。
如何在启动应用程序时将粘贴添加为customEvent:
这是我当前的app.js:
import Ember from 'ember';
import Resolver from './resolver';
import loadInitializers from 'ember-load-initializers';
import config from './config/environment';
let App;
Ember.MODEL_FACTORY_INJECTIONS = true;
App = Ember.Application.extend({
modulePrefix: config.modulePrefix,
podModulePrefix: config.podModulePrefix,
Resolver
});
loadInitializers(App, config.modulePrefix);
export default App;
我在https://github.com/bartocc/stackoverflow-2176861处安装了一个演示Ember.js 2.9应用程序,演示了下面的代码。
这里是一个示例app.js
,用于配置Ember.js以侦听paste
事件:
// /app/app.js
import Ember from 'ember';
import Resolver from './resolver';
import loadInitializers from 'ember-load-initializers';
import config from './config/environment';
let App;
Ember.MODEL_FACTORY_INJECTIONS = true;
App = Ember.Application.extend({
modulePrefix: config.modulePrefix,
podModulePrefix: config.podModulePrefix,
Resolver,
// This is how you make your ember app listen the paste event
customEvents: {
paste: 'paste'
}
});
loadInitializers(App, config.modulePrefix);
export default App;
在the Ember.js 2.9 API中查找更多信息。
然后,使任何组件通过以下方法监听paste
事件:
import Ember from 'ember';
export default Ember.Component.extend({
paste(event) {
const text = event.originalEvent.clipboardData.getData('Text');
alert(`you've just pasted the text '${text}'`);
}
});
