vue以组件或者插件的形式实现throttle或者debounce

 <div v-for="a in 3" :key="a" v-demo:getData="a">指令</div> //getData是函数名，a是传入的参数  directives: {  demo: {   bind(el: Element, binding: any, vnode: VNode) {    const that: any = vnode.context    // console.log(binding, vnode)    // console.log(binding.arg, binding.value)    if (!that[binding.arg].isBind){ // 打上标记，如果已经转换了，就不转了     that[binding.arg] = deb(that[binding.arg])     that[binding.arg].isBind = true    }    el.addEventListener('click', function T(event: Event): void{     that[binding.arg](binding.value)    })   },  }, },
