需求: 新内容出现时滚到到底端html
1 定义js钩子代码this
const Hooks = {} Hooks.Scroll = { updated () { this.el.scrollTop = this.el.scrollHeight }, mounted () { this.el.scrollTop = this.el.scrollHeight } } const liveSocket = new LiveSocket('/live', Socket, { hooks: Hooks })
2 在 html 元素上引用钩子code
<div phx-hook="Scroll">
很简单地实现了对js 代码的调用.htm
