好的,我正在使用 PHP 按目录加载图像列表:

<?php
# fetch image details
$images = getImages("marc/img/livingrooms/");

# display on page
foreach($images as $img) {
echo "<li><img src=\"{$img['file']}\" title=\"\" alt=\"\"></li>\n";
}
?>

然后我使用 Galleria JQuery 插件将这些项目设置为画廊的样式:

$(document).ready(function(){

$('.dynolist').addClass('gallery_group'); // adds new class name to maintain degradability

$('ul.gallery_group').galleria({
history : true, // activates the history object for bookmarking, back-button etc.
clickNext : true, // helper for making the image clickable
insert : '#main_image', // the containing selector for our main image
onImage : function(image,caption,thumb) { // let's add some image effects for demonstration purposes

// fade in the image & caption
image.css('display','none').fadeIn(1000);
caption.css('display','none').fadeIn(1000);

// fetch the thumbnail container
var _li = thumb.parents('li');

// fade out inactive thumbnail
_li.siblings().children('img.selected').fadeTo(500,0.3);

// fade in active thumbnail
thumb.fadeTo('fast',1).addClass('selected');

// add a title for the clickable image
image.attr('title','Next image >>');
},
onThumb : function(thumb) { // thumbnail effects goes here

// fetch the thumbnail container
var _li = thumb.parents('li');

// if thumbnail is active, fade all the way.
var _fadeTo = _li.is('.active') ? '1' : '0.3';

// fade in the thumbnail when finnished loading
thumb.css({display:'none',opacity:_fadeTo}).fadeIn(1500);

// hover effects
thumb.hover(
function() { thumb.fadeTo('fast',1); },
function() { _li.not('.active').children('img').fadeTo('fast',0.3); } // don't fade out if the parent is active
)
}
});
});

问题是我需要为从该列表中提取的第一个项目提供“事件”类,因此第一个图像将加载到幻灯片中。除了加载第一个图像之外,其他一切现在都可以正常工作。

有什么建议吗?

最佳答案

$('selector:first').addClass('active');

也许?

或者怎么样

# display on page
$class = 'class="active" ';
foreach($images as $img) {
echo "<li><img ".$class."src=\"{$img['file']}\" title=\"\" alt=\"\"></li>\n";
$class="";
}
