节流函数-throttleCall
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
