我使用React和Firebase 我想要检索名为" Phone"的数据。有没有办法检索它? 当我在console.log时,我只能得到"用户"
const ref = firebase.database().ref('Users');
ref.once("value").then(function(snapshot) {
let key = snapshot.child(this.state.username).val();;
console.log(key);
});

这是获得标题的一种方法:
const pressButton1 = () => {
const MyView = Mn.View.extend({
template: _.template('<div><input type="button" value="Click me to see Component 1" onclick="pressButton1()" id="first-region" /></div>'),
regions: {
firstRegion: '#first-region',
secondRegion: '#second-region',
thirdRegion: '#third-region',
}
});
const myView = new MyView();
myView.render();
$('body').append(myView.$el);
let loadView = require('./components/cmp1/view').default
console.log(loadView)
myView.getRegion('firstRegion').show(new loadView())
//$(document).foundation();
};
pressButton1();
如果您是Firebase的新用户,我建议您使用Firebase codelab for web developers,其中包含此主题和许多其他主题。
