The code _javascript skill of JavaScript to implement sleep function

However, the two functions are asynchronous, and the code behind them will continue to execute during the timing. Then write your own sleep () function, the Internet also spread some implementation methods, but I found the following method is simple and practical, so here to share with you:

Copy Code code as follows:

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 ()));

It's a good idea to use this function if everyone's program has a less precise sleep () function.

The following is more complicated, the need for friends can also refer to:

Copy Code code as follows:

function Sleep (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);
}
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");
}
}
