vue常用自定义指令directives防抖和一键复制 防抖v-throttle自定义指令实现 // 1.设置v-throttle自定义指令Vue.directive('throttle', {bind:(el, binding) =>{letthrottleTime = binding.value;// 防抖时间if(!throttleTime) {// 用户若不设置防抖时间,则默认2sthrottleTime =2000; }letcbFun; el.addEventListe...

我们先看下v-throttleClick要实现的效果:指令接受一个回调函数,当给元素绑定这个指令的时候,点击该元素则会以节流的形式触发改回调函数。同时接收一个 arg 作为节流事件,默认 1000ms 实现起来其实很简单 <template>点击V我50吃鸡脚</template>const vThrottleClick = (el, bind) => {let isPass = true;el...
