目前我的方法是，用一個全局變量將子組件render時的虛擬dom實例保存下來，以方便在父組件中調用。那么問題就是如何不用變量直接在父組件中直接拿到子組件的虛擬dom呢？//?全局變量，用于記錄每個子組件的虛擬DOM實例 ????var?childrenComponent=[]; ???? ????//?子組件 ????var?Child?=?React.CreateClass({ ????????componentDidMount:?function?(){ ????????????//?將組件最后的react實例保存下來，方便在父組件中調用其屬性和方法。 ? ????childrenComponent.push(this); ? }, ????????render:function?(){ ????????????return( ????????????????<p>this?is?a?child?component,number:{this.props.index}</p> ????????????) ????????} ????}) ???? ????//父組件 ????var?Parent?=?React.CreateClass({ ????????handleCilck:function?(){ ????????????//這里拿到子組件的虛擬DOM，以進行一些操作 ????????????console.log(childrenComponent[0]) ????????}, ????????render:function?(){ ????????????var?children?=?[]; ????????????var?newChild?=?function?(i){ ????????????????return?<Child?index={i}?/>? ????????????}? ????????????for(var?i=0,?i<5,?i++){ ????????????????children.push(newChild(i)) ????????????} ????????????return( ????????????????<div> ????????????????????{children} ????????????????????<button?onClick={this.handleClick}></button> ????????????????</div> ????????????) ????????} ????}) ???? ????React.render( ????<Parent?/>, ????document.body );
