use*_*782 1 html javascript jquery flexslider
我想在移动设备中显示3个缩略图,在弹性滑块中显示4个桌面缩略图.为此我使用带有动态最小/最大范围版本的flex滑块的Carousel.如果您调整该页面的大小,您会看到根据浏览器窗口宽度更改的thmubanils数量.但是当我使用相同的代码在我的网站或jsfiddle或任何地方它不起作用.这里是jsfiddle证明和相同的代码:
(function() {
// store the slider in a local variable
var $window = $(window),
flexslider = {
vars: {}
};
// tiny helper function to add breakpoints
function getGridSize() {
return (window.innerWidth < 600) ? 2 :
(window.innerWidth < 900) ? 3 : 4;
}
$window.load(function() {
$('.flexslider').flexslider({
animation: "slide",
animationLoop: false,
itemWidth: 210,
itemMargin: 5,
minItems: getGridSize(), // use function to pull in initial value
maxItems: getGridSize() // use function to pull in initial value
});
});
// check grid size on resize event
$window.resize(function() {
var gridSize = getGridSize();
flexslider.vars.minItems = gridSize;
flexslider.vars.maxItems = gridSize;
});
}());.container {
width: 70%;
max-width: 1100px;
margin: auto;

<!-- items mirrored twice, total of 12 -->
</ul>
</div>我想在github上报告这是一个问题,但我很担心为什么它会在实际的flex滑块网站上运行.
奇怪的是,这个滑块的官方文档遗漏了这个重要信息.您必须在flexslider启动或加载时将滑块实例设置为全局变量.
工作实例.
