This is not really a prototype question, but I figured some here
might be able to assist..
I am building an image scanner like Apple just added to iPhoto and
the new galleries for .mac.
For those who haven''t seen it, it lets you scrub through thumbnails
of what is in the gallery by dragging your mouse over the preview
icon, depending on your position (left to right) over the thumbnail
it changes the img.src to a new image.
Any how I have this working now, but it is changing the image src on
ever mouse move, even if the img doesnnt need to change.
For example if my thumb image is 100 px wide, and my list of images
to scan only has 4 images, nothing should change until I am 1/4 the
way across the thumbnail.
So, my quick choice was to compare the current image source to the
one I want to change to . If they are the same I do nothing if
different I update the image src.
var newthumb = "/path/to/image.jpg"; // Actually figured out in other
code, this is just here for reference..
var thumb = $(''thumb'');
if (thumb.src != newthumb){
thumb.src = newthumb;
console.log(thumb.src);
}
The problem I am having is that thumb.src always equals http://
www.domain.com/path/to/image.jpg
even if I just set it to "/path/to/image.jpg";
So my question is how do I compare this properly?

Alex, I think the src attribute returns the fully qualified path to your image, i.e. http://domain.ext/path/to/image.ext On 10/4/07, Alex Duffield <Alex@incontrolsolutions.com> wrote:> > This is not really a prototype question, but I figured some here might be > able to assist.. > > I am building an image scanner like Apple just added to iPhoto and the new > galleries for .mac. > > > For those who haven't seen it, it lets you scrub through thumbnails > of what is in the gallery by dragging your mouse over the preview icon, > depending on your position (left to right) over the thumbnail it changes the > img.src to a new image. > > > Any how I have this working now, but it is changing the image src on ever > mouse move, even if the img doesnnt need to change. > > > For example if my thumb image is 100 px wide, and my list of images to > scan only has 4 images, nothing should change until I am 1/4 the way across > the thumbnail. > > > So, my quick choice was to compare the current image source to the one I > want to change to .
