老师，event-bus.js中clear和hasEvent方法中的emitBus属性是在哪里加上去的吗？没有找到 #30
Description
clear() {
this.emitBus = {}
}
hasEvent(eventName) {
return Object.keys(this.emitBus).includes(eventName)
}
{{ message }}
clear() {
this.emitBus = {}
}
hasEvent(eventName) {
return Object.keys(this.emitBus).includes(eventName)
}
