我正在使用Fancybox v2.0.5和一组图像,并希望以随机顺序显示整组图像。我尝试了各种jQuery shuffle脚本,但它们似乎没有与Fancybox集成。
我想用jQuery而不是php或其他服务器端脚本来做这件事。
有什么建议吗?

您可以随机使用数组中的数组和弹出值,直到没有剩余,通过自定义插件randomiseGallery
完成:

我想你想要随机幻灯片放映的这个功能在后台运行。
不幸的是 javascript 没有与php的shuffle()
函数相同的功能。但是,您可以使用任何javascript改编的Fisher-Yates算法对javascript进行随机排序。
让我们从https://stackoverflow.com/a/6274398/1055987
中选择一个function shuffle(array) {
// Fisher-Yates shuffle for javascript
// as in https://stackoverflow.com/a/6274398/1055987
var counter = array.length, temp, index;
// While there are elements in the array
while (counter > 0) {
// Pick a random index
index = Math.floor(Math.random() * counter);
// Decrease counter by 1
counter--;
// And swap the last element with it
temp = array[counter];
array[counter] = array[index];
array[index] = temp;
}
return array;
}
我们将使用上面的函数随机化到我们的(手动构建的)库并使用fancybox提供它,因此不需要任何html而是fancybox触发器
<a class="fancybox" href="javascript:;">open random gallery</a>
然后画廊将存储在像
这样的数组中var gallery = [{
href: "http://farm6.staticflickr.com/5471/9036958611_fa1bb7f827_b.jpg",
title: "Westfield Waterfalls - Middletown CT Lower (Graham_CS)"
}, {
href: "http://farm4.staticflickr.com/3824/9041440555_2175b32078_b.jpg",
title: "Calm Before The Storm (One Shoe Photography Ltd.)"
}, {
href: "http://farm3.staticflickr.com/2870/8985207189_01ea27882d_b.jpg",
title: "Lambs Valley (JMImagesonline.com)"
}, {
href: "http://farm4.staticflickr.com/3677/8962691008_7f489395c9_b.jpg",
title: "Grasmere Lake (Phil 'the link' Whittaker (gizto29))"
}];
...我们会在每次点击触发器(.fancybox
选择器)时将其随机化,如:
jQuery(document).ready(function($) {
$(".fancybox").on("click", function () {
$.fancybox(shuffle(gallery), {
//API options
type: "image"
});
}); // on
}); // ready
参见 JSFIDDLE
注意:我不确定这是否是你要找的,但我发现这个练习很有趣,最终对其他人应用很有用。
