destination is not defined
shouldComponentUpdate:function(newPros,newState){
if(newState.disnum < 5){
return true;
}else{
console.log("退出");
ReactDOM.unmountComponentAtNode(destination);
return false;
}
},
componentWillUnmount:function(){
console.log('willunmount')
return;
}
前面都是正确的，到了unmount这块就不行了。报destination没有定义：destination is not defined，怎么破？？？
