（节流）js防止重复频繁点击或者点击过快方法

<script>
    var isClick = true;
    $("button").on("click",function(){
        if(isClick) {
            isClick = false;
            //事件
            console.log(‘我被点击了‘);
            //定时器
            setTimeout(function() {
                isClick = true;
            }, 1000);//一秒内不能重复点击
        }else{
             console.log(‘请勿过快点击‘);
      }
    });
</script>

var lastClick;   
lockClick(){
    var nowClick = new Date();
    if (lastClick === undefined) {
        lastClick = nowClick;
        return true;
    } else {
        if (Math.round((nowClick.getTime() - lastClick.getTime())) > 500) {
            lastClick = nowClick;
            return true;
        }
        else {
            lastClick = nowClick;
            return false
        }
    }
}
 
    this.on(‘click‘,()=>{
        if (this.lockClick()) {
            //你的函数代码
        }
    })
