Create an interval to change image in jQuery?

Solution 1
new and default are reserved words in javascript. You cannot use them.
To create an interval you should use setInterval
:
setInterval(function() {
// do something
// ...
}, 1000); // <- 1000ms = 1s
[See it in action]
jQuery(document).ready(function() {
var timer, imgsrc, cnt = 0;
$('.video-thumb img').bind('mouseover', function() {
// if there is no timer
if (!timer) {
var $t = $(this);
// get the image src
imgsrc = $t.attr('src').replace('default.jpg','');
// start a new timer
timer = setInterval(function() {
// periodically change the src
$t.attr('src', imgsrc + (cnt+1) + ".jpg");
// and adjust the counter
cnt = ( cnt + 1 ) % 3; // 0, 1, 2
}, 1000); // <- 1000ms = 1s
}
}).bind('mouseout',function() {
// stop rotation
if (timer) {
clearInterval(timer);
timer = null;
}
// set the default img
$(this).attr('src', imgsrc + 'default.jpg');
});
});

You can see my answer working here:
HTML
<div class="video-thumb">
<img src="http://i2.ytimg.com/vi/Q1yo3mco40U/default.jpg" />
</div>
<div id="counter">0</div>
JavaScript
$(document).ready(function() {
var images = [];
images[0] = "http://i2.ytimg.com/vi/Q1yo3mco40U/default.jpg";
images[1] = "http://i2.ytimg.com/vi/ivmoCcYLrEk/default.jpg";
images[2] = "http://i3.ytimg.com/vi/f7d8luQ6p2Q/default.jpg";
images[3] = "http://i1.ytimg.com/vi/XzFmOKNf8sc/default.jpg";
images[4] = "http://i2.ytimg.com/vi/-2m1e4g2MFM/default.jpg";
images[5] = "http://i1.ytimg.com/vi/lK2TSYBh7fw/default.jpg";
var loop;
var i = 0;
var counter = $("#counter");
$('.video-thumb img').mouseover(function() {
var image = this;
loop = setInterval(function() {
if (i < images.length - 1) {
i++;
$(image).attr('src',images[i]);
} else {
i = 0;
$(image).attr('src',images[i]);
}
counter.html(i);
}, 1000);
}).mouseout(function() {
clearInterval(loop);
i = 0;
$(this).attr('src', images[i]);
counter.html(i);
});
});

I have a working script like this:
jQuery(document).ready(function(){ $('.video-thumb img').bind('mouseover',function(){ var new = $(this).attr('src').replace(/default.jpg/,'1.jpg'); $(this).attr('src',new); }).bind('mouseout',function(){ var default = $(this).attr('src').replace(/[0-9].jpg/,'default.jpg'); $(this).attr('src',default); }); });
Yeah, you guessed right. It's made to change YouTube's thumbnail on interval. However, I have no idea, how to create the interval. It now changes the thumbnail to 1.jpg, which is another thumbnail, but it should next change the image to 2.jpg in 1 second and so on.
The whole snippet should probably be written from scratch. Advice?
Hope you understood :-D
EDIT: I changed the variable-names from finnish words, I don't use them. Just in this example.
