前端原生 JS 触发自定义事件的时候怎么传递数据

    原生 JS 通过 new Event(eventName) 或 new CustomEvent(eventname) 自定义事件

    通过 target.dispatch(eventObject) 触发自定义事件

    但是这样触发事件没办法传递数据过去, 有没有办法能像 JQuery 的 trigger 方法触发事件的时候把数据也传过去

    PS: 我去看了 JQuery 源码, 水平有限看不太懂

  • jquery
  • eventname
  • 事件
  • 定义

    挂 eventObject 上不行吗？

    dispatch -> dispatchEvent 不小心打错了

    @ayase252 我傻了==, 可以挂 eventObject 上, 但是 JQuery 那种貌似不是挂事件对象上的

    @ayase252 我懂了, 挂 eventObject 然后套层函数处理一下就可以像 JQuery 那样了
