线上的input 事件绑定的方法 报警群总是报undefined 开发时却遇不到 一脸懵逼


Start with the reported and its inputChange handler, then reproduce the production-only path that produces an undefined event. Check the event behavior at the component boundary and add a regression case once the failing path is isolated. Done means the warning no longer occurs and normal input values are emitted.
