节流函数在lodash中有现成的工具函数,有时希望精简代码可以自己diy一个
var throttleCall=function(fn,interval){
var enabled=true
return function(){
if(enabled){
fn()
enabled=false
setTimeout(function(){enabled=true},interval)
}
}
}
test:
var fn=function(){
console.log('hello')
}
var throttleFn=throttleCall(fn,3000)
throttleFn()
throttleFn()
throttleFn()
输出:
hello
