1.函数节流代码
var cd =false
function kill(){
console.log("释放技能")
}
var element = document.getElementById('1')
element.onclick=function(){
if(cd){
//什么也不做
}else{
kill()
cd=true
setTimeout(function(
){
cd = false
},5000)
}
}
2.函数防抖
var timer =null
function takeOut(){
console.log('送外卖啦')
}
var ele = document.getElementById('2')
ele.onclick=function(){
if(timer){
window.clearTimeout(timer)
}
timer=setTimeout(function(){
takeOut()
timer=null
},5000)
}
