JavaScript implementation of sleep paused function code like Java, C # _javascript Tips

Here's how I implement it:
Code

Copy Code code as follows:

<script type= "Text/javascript" >
function test ()
{
var s= "javascript--suspend function";
SetTimeout (
function () {
eval (test); The code after the return is executed, which is "alert (s);"
},
2000
); Two seconds to execute.
Return Run to this and exit
alert (s);
}
function Sleep (func)
{
if (func = null)
{
return;
}
var reg=/[\n\r]/g;
var funcstr = func.tostring (). Replace (Reg, ' "); Replace carriage return and line feed
reg =/.+?sleep.+?return;/;
Funcstr = ' {' + funcstr.replace (Reg, ');//Remove code before function Test,return
return funcstr;
}
Test ();
</script>

This may have some limitations, can not be as intuitive as the sleep function in Java, C #, easy to use.
But I think it's quite interesting, just take it out and share it with you.
