Hello All,
I have this Jquery code
(function($){
$.expr[':'].linkingToImage = function(elem, index, match){
// This will return true if the specified attribute contains a valid link to an image:
return !! ($(elem).attr(match[3]) && $(elem).attr(match[3]).match(/\.(gif|jpe?g|png|bmp)$/i));
};
$.fn.imgPreview = function(userDefinedSettings){
var s = $.extend({
/* DEFAULTS */
// CSS to be applied to image:
imgCSS: {},
// Distance between cursor and preview:
distanceFromCursor: {top:2, left:2},
// Boolean, whether or not to preload images:
preloadImages: true,
// Callback: run when link is hovered: container is shown:
onShow: function(){},
// Callback: container is hidden:
onHide: function(){},
// Callback: Run when image within container has loaded:
onLoad: function(){},
// ID to give to container (for CSS styling):
containerID: 'imgPreviewContainer',
// Class to be given to container while image is loading:
containerLoadingClass: 'loading',
// Prefix (if using thumbnails),
e.g. 'thumb_'
thumbPrefix: '',
// Where to retrieve the image from:
srcAttr: 'rel'
}, userDefinedSettings),
$container = $('<div/>').attr('id', s.containerID)
.append('<img/>').hide()
.css('position','absolute')
.appendTo('body'),
$img = $('img', $container).css(s.imgCSS),
// Get all valid elements (linking to images / ATTR with image link):
$collection = this.filter(':linkingToImage(' + s.srcAttr + ')');
// Re-usable means to add prefix (from setting):
function addPrefix(src) {
return src.replace(/(\/?)([^\/]+)$/,'$1' + s.thumbPrefix + '$2');
}
if (s.preloadImages) {
(function(i){
var tempIMG = new Image(),
callee = arguments.callee;
tempIMG.src = addPrefix($($collection[i]).attr(s.srcAttr));
tempIMG.onload = function(){
$collection[i + 1] && callee(i + 1);
};
})(0);
}
$collection
.mousemove(function(e){
$container.css({
top:
e.pageY + s.distanceFromCursor.top + 'px',
left:
e.pageX + s.distanceFromCursor.left + 'px'
});
})
.hover(function(){
var link = this;
$container
.addClass(s.containerLoadingClass)
.show();
$img
.load(function(){
$container.removeClass(s.containerLoadingClass);
$img.show();
s.onLoad.call($img[0], link);
})
.attr( 'src' , addPrefix($(link).attr(s.srcAttr)) );
s.onShow.call($container[0], link);
}, function(){
$container.hide();
$img.unbind('load').attr('src','').hide();
s.onHide.call($container[0], this);
});
// Return full selection, not $collection!
return this;
};
})(jQuery);
It works perfectly in all browsers apart from IE, which it does nothing, no errors, no clues? I have a funny feeling IE doesn't support attr? Can anyone offer any advice?
