如何在脚本中暂停

Question

嘿，我有代码，每次执行后都必须延迟。但是，即使用户正在滚动，执行代码也不必工作。现在只有一次延迟

function delayf(){
    delay = false;
    return delay;
 }


var delay = true;

$('.window').on('mousewheel', function (event) {

    var elemId = $(this).attr('id'),
    scrollDir = event.deltaY;
    var indicatorL = $(".indicator_main").data("counter"); 

     if (elemId == 'steps' && scrollDir < 0 && delay === false) {
        if(indicatorL != "4"){
            indicatorL = indicatorL + 1;
            $(".indicator_main").data("counter", indicatorL);
            $(".indicator_main").animate({ "left": "+=25%" }, "slow" );
            $(".indicator_num").text("0" + indicatorL);

        }
     }

    if(elemId == 'scen_wraper1' || elemId == 'scen_wraper2' || elemId == 'steps'){
        event.preventDefault();
    }
    console.log(delay);
    delay = true;
    delay = setTimeout(delayf, 2000);


});
