refs可以拿子子組件的props/state/方法；
findDOMNOde拿到的是原生的標(biāo)簽相關(guān)屬性；
import { findDomNode } from 'react-dom';
let initialNode = findDomNode(this.refs.navBox);
getNodeInstance() {
const nodeInstance = this.refs.navBox;
}
function WapShop() {
return (
<div>
<NavBox ref="navBox" />
</div>
);
}
方法1：
let senderName = ReactDOM.findDOMNode(this.refs['sender-name']);
let nleft = senderName.style.left;
let ntop = senderName.style.top;
let nwidth = senderName.style.width;
let nheight = senderName.style.height;
console.log(nleft,ntop,nwidth,nheight);
方法2：
let rstyle = this.refs['sender-name'].style;
let rleft = rstyle.left;
let rtop = rstyle.top;
let rwidth = rstyle.width;
let rheight = rstyle.height;
console.log(rleft,rtop,rwidth,rheight);
方法3：
let computedStyle=document.defaultView.getComputedStyle(ReactDOM.findDOMNode(this.refs['sender-name']),null);
let cleft = computedStyle.left;
let ctop = computedStyle.top;
console.log(cleft,ctop);
