ReactDOM.render应该返回 根组件的实例
from anu.
updateComponent方法中的this.forceUpdate应该改成instance.forceUpdate
from anu.
原patchRef方法理解有误,函数形式的传参是DOM 不是组件实例
function patchRef(instance, ref, dom, mount) {
if (typeof ref === 'function') {
ref(dom)
} else if (typeof ref === 'string') {
instance.refs[ref] = dom
dom.getDOMNode = getDOMNode
}
}
