我一直在研究一個小的jQuery插件,它可以在鼠標懸停在圖像上時創建類似iPhoto的預覽。如果我只有一組圖像,這一切都很好。只要我爲標記添加多個.preview設置,我的插件就會查找所有這些標記,並在每個圖像下方顯示指標總數。僅針對指定元素的問題
這裏是JS:
$(document).ready(function() {
// launch preview browser
$('.preview').previewBrowser();
});
(function($) {
$.fn.previewBrowser = function() {
return this.each(function() {
// get dom
var $viewport = $(this).css('overflow', 'hidden'),
$container = $viewport.children('ul'),
$items = $container.children('li'),
$single = $items.filter(':first');
// set viewport to correct size
$viewport.css({ height: $single.height(), width: $single.width() });
// set container to correct width
$container.css({ height: $single.height(), width: $items.length * $single.width() });
// float items
$items.css({ float: 'left' });
// add indicator to dom
var indicator = '';
for (i = 0; i < $items.length; i++) {
indicator += '<li class="left">O</li>';
}
$(indicator).appendTo('.indicator');
// set default indicator
$('.indicator li:eq(0)').css('color', 'red');
// set scrolling position while mouseover
$viewport.bind('mousemove.previewBrowser', function(evt) {
x = evt.pageX - this.offsetLeft;
offset = Math.floor(x/($single.width()/$items.length)) * $single.width();
$(this).animate({ scrollLeft: offset }, 1);
// get current item
currentItem = (offset/$single.width());
// set current color
$('.indicator li').not('.indicators li:eq(' + currentItem + ')').css('color', 'black');
$('.indicator li:eq(' + currentItem + ')').css('color', 'red');
return false;
});
// set default image on mouseout
$viewport.bind('mouseleave.previewBrowser', function(evt) {
$(this).animate({ scrollLeft: 0 }, 1);
// set current color
$('.indicator li').not('.indicator li:eq(0)').css('color', 'black');
$('.indicator li:eq(0)').css('color', 'red');
});
});
};
})(jQuery);
這裏是標記:

我知道我錯了目標的項目,但我只是無法弄清楚如何做是正確的。
