js实现睡眠

//js暂停函数
function Pause(obj, iMinSecond) {
    if (window.eventList == null)
        window.eventList = new Array();
    var ind = -1;
    for (var i = 0; i < window.eventList.length; i++) {
        if (window.eventList[i] == null) {
            window.eventList[i] = obj;
            ind = i;
            break;
        }
    }
    if (ind == -1) {
        ind = window.eventList.length;
        window.eventList[ind] = obj;
    }
    setTimeout("GoOn(" + ind + ")", iMinSecond);
}
// js继续函数
function GoOn(ind) {
    var obj = window.eventList[ind];
    window.eventList[ind] = null;
    if (obj.NextStep)
        obj.NextStep();
    else
        obj();
}

    this.NextStep = function() {
        alert("2");
    }
