利用javascript怎么做sleep功能？

[孟子E章]

statement1;
wait (someDelay);
statement2;
you would stuff the code into functions
function statement1 () {
// your code here
}
function statement2 () {
// your code here
}
and call
statement1();
setTimeout('statement2()', someDelay);

If you wanted (pseudo code)
while (someCondition) {
statement1;
wait (someDelay)
}
you code
var tid;
function statement1 () {
// your code here
if (!condition)
clearInterval(tid);
}
tid = setInterval('statement1()', someDelay);

Note that both setInterval and setTimeout return a timer id you can use
to clear the scheduled execution e.g.
var tid = setTimeout('js code here', delayInMilliseconds);
...
clearTimeout(tid);
respectively
var tid = setInterval('js code here', delayInMilliseconds);
...
clearInterval(tid);



function pause(numberMillis) {
var now = new Date();
var exitTime = now.getTime() + numberMillis;
while (true) {
now = new Date();
if (now.getTime() > exitTime)
return;
}
}
