问题是这样的：
我想在页面中使用两个忍者滑块来查看包含“ gallery”类的div中的图像。 页面的链接：http://www.alpastomendrisio.ch/galleria/riparazione-mobile.php
我的代码html：

这是我的costum javascript文件：
function lightbox(idx) {
//show the slider's wrapper: this is required when the transitionType has been set to "slide" in the ninja-slider.js
var ninjaSldr = document.getElementById("ninja-slider");
ninjaSldr.parentNode.style.display = "block";
nslider.init(idx);
var fsBtn = document.getElementById("fsBtn");
fsBtn.click();
}
function fsIconClick(isFullscreen, ninjaSldr) { //fsIconClick is the default event handler of the fullscreen button
if (isFullscreen) {
ninjaSldr.parentNode.style.display = "none";
}
}
$(document).ready(function() {
var year = $('#slct').val();
$('#' + year).show();
$('#slct').on('change', function() {
var change = this.value;
$('#' + year).hide();
$('#' + change).show();
year = this.value;
});
});
对于每个了解插件的人，都知道从哪里获取代码（http://www.menucool.com/slider/show-image-gallery-on-modal-popup）。
感谢您的帮助。
