我在测试页面上使用了Lazy Load Jquery插件:http://bloghutsbeta.blogspot.com/2012/03/testing-2_04.html 这是lazyload的缩小脚本: 代码:
<script src="http://files.cryoffalcon.com/javascript/jquery.lazyload.min.js" type="text/javascript" charset="utf-8"></script>
这个是触发延迟加载: 代码:
<script type="text/javascript" charset="utf-8">
$(function() {
$("img").lazyload({
effect : "fadeIn"
});
});
</script>
在上面的脚本中我添加了fadeIn效果,我不知道我是否按照脚本编写做得对,我不擅长脚本^^所以,如果写的很好,我想建议一下或者有一些逗号错误。
但这不是我的重要问题,所有上述延迟加载插件都与我用于排序的QuickSand Jquery插件一起使用。 QuickSand Jquery插件需要回调函数,如果它是工具提示或延迟加载,那么有人可以告诉我如何使懒惰加载与quicksand jquery一起工作。 这是流沙的剧本:
代码:
<script type="text/javascript">
(function(cash) {
$.fn.sorted = function(customOptions) {
var options = {
reversed: false,
by: function(a) {
return a.text();
}
};
$.extend(options, customOptions);
$data = $(this);
arr = $data.get();
arr.sort(function(a, b) {
var valA = options.by($(a));
var valB = options.by($(b));
if (options.reversed) {
return (valA < valB) ? 1 : (valA > valB) ? -1 : 0;
} else {
return (valA < valB) ? -1 : (valA > valB) ? 1 : 0;
}
});
return $(arr);
};
})(jQuery);
$(function() {
var read_button = function(class_names) {
var r = {
selected: false,
type: 0
};
for (var i=0; i < class_names.length; i++) {
if (class_names[i].indexOf('selected-') == 0) {
r.selected = true;

var $list = $('#data');
var $data = $list.clone();
var $controls = $('ul#gamecategories ul');
$controls.each(function(i) {
var $control = $(this);
var $buttons = $control.find('a');
$buttons.bind('click', function(e) {
var $button = $(this);
var $button_container = $button.parent();
var button_properties = read_button($button_container.attr('class').split(' '));
var selected = button_properties.selected;
var button_segment = button_properties.segment;
if (!selected) {
$buttons.parent().removeClass('selected-0').removeClass('selected-1').removeClass('selected-2');
$button_container.addClass('selected-' + button_segment);
var sorting_type = determine_sort($controls.eq(1).find('a'));

var $filtered_data = $data.find('li');
} else {
var $filtered_data = $data.find('li.' + sorting_kind);
}
if (sorting_type == 'size') {
var $sorted_data = $filtered_data.sorted({

return parseFloat($(v).find('span').text());
}
});
} else {
var $sorted_data = $filtered_data.sorted({
by: function(v) {
return $(v).find('strong').text().toLowerCase();
}
});
}
$list.quicksand($sorted_data, $preferences, function () { $(this).tooltip (); } );
}
e.preventDefault();
});
});
var high_performance = true;
var $performance_container = $('#performance-toggle');
var $original_html = $performance_container.html();
$performance_container.find('a').live('click', function(e) {
if (high_performance) {
$preferences.useScaling = false;
$performance_container.html('CSS3 scaling turned off. Try the demo again. <a href="#toggle">Reverse</a>.');

答案 0 :(得分:0)
你可以用这个:
$list.quicksand($sorted_data, $preferences, function(){
$(this).tooltip ();
$("img").lazyload({
effect : "fadeIn"
});
});
