javascript - JS: How to reset index inside a for-loop so it loops again without lots of timeout errors? -

-

i'm working on custom js thumbnail changer , works. want loop thumbnails indefinitely. @ moment goes until i==thumbs , stops. here codesnipped:

for (var = 1; <= thumbs; i++) {     timer[i] = settimeout("thumbchange('" + image_id + url + + '.jpg' + "')", * 100 * 10); }

what want is, if i reaches thumbs (the last thumbnail), reset i 1 , play for loop again. can't work.

i tried lots of things including following, crashes browser because of timeouts: can somehow around timeout problem completely?

for (var = 1; <= thumbs; i++) {     timer[i] = settimeout("thumbchange('" + image_id + url + + '.jpg' + "')", * 100 * 10);      if (i == thumbs) {         = 1;          cleartimeout(timer[i]);          continue;     } }

alternatively use setinterval automatically loop forever or until clear it. note in setinterval , settimeout should use functions not evaluation strings.

var img = 0;  thumbchange (image_id + url + img + '.jpg'); // initialise img 0 window.setinterval (function () {  // invoked once per interval   if (++img == thumbs) // inc image , reset 0 when reaches thumbs     img = 0;   thumbchange (image_id + url + img + '.jpg'); // image change }, 1000);  // 1 second per image
