JavaScript实现Sleep函数的代码_javascript技巧

代码如下:
console.log('start...');
console.log('now time: ' + Date(/\d{10,10}/.exec(Date.now())));
function sleep(sleepTime) {
for(var start = Date.now(); Date.now() - start <= sleepTime; ) { }
}
sleep(5000); // sleep 5 seconds
console.log('end...');
console.log('end time: ' + Date(/\d{10,10}/.exec(Date.now())));

如果大家的程序对sleep()函数的精确度不那么高的话，使用这个函数是个不错的选择

下面这个是复杂些的，需要的朋友也可以参考一下：
代码如下:
function Sleep(obj,iMinSecond)
{
if (window.eventList==null)
window.eventList=new Array();
var ind=-1;
for (var i=0;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);
}
function GoOn(ind)
{
var obj=window.eventList[ind];
window.eventList[ind]=null;
if (obj.NextStep) obj.NextStep();
else obj();
}
function Test()
{
alert("sleep");
Sleep(this,100);
this.NextStep=function()
{
alert("continue");
}
}
