Disabling Mousemove Scrolling?
Hey everyone!
I am making a website and am having a key issue. The site uses an image gallery script that sets the thumbnail image as the background of the page and enables the user to see the various parts of the image by moving their mouse across the page. When they click a thumbnail the navigation and thumbnail images disappear as well and are reappear via a "view thumbnails" button. What I want to do is disable the mouse moving scrolling when you click the view thumbnails button as well, but still have the image in the background. I have tried coding it a few ways, but am stuck. Does anyone have any ideas? Here is the script:
<script type="text/javascript">
$(function() {
//current thumb's index being viewed
var current = -1;
//cache some elements
var $btn_thumbs = $('#fp_thumbtoggle');
var $loader = $('#fp_loading');
var $btn_next = $('#fp_next');
var $btn_prev = $('#fp_prev');
var $thumbScroller = $('#thumbScroller');
//total number of thumbs
var nmb_thumbs = $thumbScroller.find('.content').length;
//preload thumbs
var cnt_thumbs = 0;
for(var i=0;i<nmb_thumbs;++i){
var $thumb = $thumbScroller.find('.content:nth-child('+parseInt(i+1)+')');
$('<img/>').load(function(){
++cnt_thumbs;
if(cnt_thumbs == nmb_thumbs)
//display the thumbs on the bottom of the page
showThumbs(2000);
}).attr('src',$thumb.find('img').attr('src'));
}
//make the document scrollable
//when the the mouse is moved up/down
//the user will be able to see the full image
makeScrollable();
//clicking on a thumb...
$thumbScroller.find('.content').bind('click',function(e){
var $content= $(this);
var $elem = $content.find('img');
//keep track of the current clicked thumb
//it will be used for the navigation arrows
current = $content.index()+1;
//get the positions of the clicked thumb
var pos_left = $elem.offset().left;
var pos_top = $elem.offset().top;
//clone the thumb and place
//the clone on the top of it
var $clone = $elem.clone()
.addClass('clone')
.css({
'position':'fixed',
'left': pos_left + 'px',
'top': pos_top + 'px'
}).insertAfter($('BODY'));
var windowW = $(window).width();
var windowH = $(window).height();
//animate the clone to the center of the page
$clone.stop()
.animate({
'left': windowW/2 + 'px',
'top': windowH/2 + 'px',
'margin-left' :-$clone.width()/2 -5 + 'px',
'margin-top': -$clone.height()/2 -5 + 'px'
},500,
function(){
var $theClone = $(this);
var ratio = $clone.width()/120;
var final_w = 400*ratio;
$loader.show();
//expand the clone when large image is loaded
$('<img class="fp_preview"/>').load(function(){
var $newimg = $(this);
var $currImage = $('#fp_gallery').children('img:first');
$newimg.insertBefore($currImage);
$loader.hide();
//expand clone
$theClone.animate({
'opacity' : 0,
'top' : windowH/2 + 'px',
'left' : windowW/2 + 'px',
'margin-top' : '-200px',
'margin-left' : -final_w/2 + 'px',
'width' : final_w + 'px',
'height' : '400px'
},1000,function(){$(this).remove();});
//now we have two large images on the page
//fadeOut the old one so that the new one gets shown
$currImage.fadeOut(2000,function(){
$(this).remove();
});
//show the navigation arrows
showNav();
}).attr('src',$elem.attr('alt'));
});
//hide the thumbs container
hideThumbs();
e.preventDefault();
});
//clicking on the "show thumbs"
//displays the thumbs container and hides
//the navigation arrows
$btn_thumbs.bind('click',function(){
showThumbs(500);
hideNav();
});
function hideThumbs(){
$('#outer_container').stop().animate({'left':'-160px'},500);
showThumbsBtn();
}
function showThumbs(speed){
$('#outer_container').stop().animate({'left':'0px'},speed);
hideThumbsBtn();
}
function hideThumbsBtn(){
$btn_thumbs.stop().animate({'bottom':'-50px'},500);
}
function showThumbsBtn(){
$btn_thumbs.stop().animate({'bottom':'0px'},500);
}
function hideNav(){
$btn_next.stop().animate({'right':'-50px'},500);
$btn_prev.stop().animate({'left':'-50px'},500);
}
function showNav(){
$btn_next.stop().animate({'right':'0px'},500);
$btn_prev.stop().animate({'left':'0px'},500);
}
//events for navigating through the set of images
$btn_next.bind('click',showNext);
$btn_prev.bind('click',showPrev);
//the aim is to load the new image,
//place it before the old one and fadeOut the old one
//we use the current variable to keep track which
//image comes next / before
function showNext(){
++current;
var $e_next = $thumbScroller.find('.content:nth-child('+current+')');
if($e_next.length == 0){
current = 1;
$e_next = $thumbScroller.find('.content:nth-child('+current+')');
}
$loader.show();
$('<img class="fp_preview"/>').load(function(){
var $newimg = $(this);
var $currImage = $('#fp_gallery').children('img:first');
$newimg.insertBefore($currImage);
$loader.hide();
$currImage.fadeOut(2000,function(){$(this).remove();});
}).attr('src',$e_next.find('img').attr('alt'));
}
function showPrev(){
--current;
var $e_next = $thumbScroller.find('.content:nth-child('+current+')');
if($e_next.length == 0){
current = nmb_thumbs;
$e_next = $thumbScroller.find('.content:nth-child('+current+')');
}
$loader.show();
$('<img class="fp_preview"/>').load(function(){
var $newimg = $(this);
var $currImage = $('#fp_gallery').children('img:first');
$newimg.insertBefore($currImage);
$loader.hide();
$currImage.fadeOut(2000,function(){$(this).remove();});
}).attr('src',$e_next.find('img').attr('alt'));
}
function makeScrollable(){
$(document).bind('mousemove',function(e){
var top = (e.pageY - $(document).scrollTop()/2) ;
$(document).scrollTop(top);
});
}
});
</script>
Also, if you are having trouble visualizing what I am talking about, here is what it looks like in action:
