[React] React Fundamentals: transferPropsTo
the transferPropsTo method lets you easily push properties into your components to easily customize attributes.
From last two exmaples, we have BButton adn BHeart set up.
var BButton = React.createClass({
render: function() {
return (
<a className="btn btn-primary">{this.props.children}</a>
);
}
});
var BHeart =
React.createClass({
render:function(){
return <span className="glyphicon glyphicon-heart"></span>
}
});
To get more fixability, we don't want button to be 'btn-primary' and icon to be 'glyphicon-hear', we may want something else.
Here we update the code:
var BButton = React.createClass({
render: function() {
return this.transferPropsTo(
<a className="btn">{this.props.children}</a>
);
}
});
var BIcon =
React.createClass({
render:function(){
return this.transferPropsTo(<span className="glyphicon"></span>);
}
});
We take away 'btn-primay' and 'glyphicon-heart', let them just be a BButton and BIcon.
Then in the App, we can set whatever we want:
var App = React.createClass({
render: function(){
return (
<div>
<BButton className="btn-danger">I <BIcon className="glyphicon-fire"></BIcon> React</BButton>
<BButton className="btn-warning">I <BIcon className="glyphicon-heart"></BIcon> React</BButton>
<BButton className="btn-success">I <BIcon className="glyphicon-home"></BIcon> React</BButton>
</div>
);
}
});
