我当前正在使用anythingSlider插件，除了只有一个<li>以外，它的工作原理都很好。<li>是从数据库生成的，因此有时只有一个。
但是，everythingSlider插件仍然尝试在<li>中滑动，它可以通过滑动回到第一张幻灯片来工作。虽然看起来不太好。
如果只有一个<li>，有人知道阻止它滑动的方法吗？

嗨！
有人可以帮忙吗？我尝试过格雷格的解决方案，也尝试过：
if (banners<1) {
.anythingSlider({
startStopped: true,
buildNavigation: false
});
}
“横幅广告”是我要调用的变量。
这将完全禁用anythingSlider函数。
请帮助？！

To use the navigationFormatter function, you must have a function that
accepts two paramaters, and returns a string of HTML text.
index = integer index (1 based);
panel = jQuery wrapped LI item this tab references
@return = Must return a string of HTML/Text
navigationFormatter: function(index, panel){
return index + " Panel"; // This would have each tab with the text 'X Panel' where X = index
}

这有点杂凑，但只要有多个
<li>，就可以正常工作 最佳答案
尝试这个：
// this function wraps the elements in the neccessary tags to work with anything Slider
$ (document).ready(function() {
$('a.slide-link')
.wrap('<li class="slide-list-item"></li>');
$('li.slide-list-item')
.wrapAll('<ul id="slide-list"></ul>');
$('ul#slide-list')
.wrapAll('<div class="wrapper"></div>');
$('div.wrapper')
.wrapAll('<div class="anythingSlider internalSlider"></div>');
if(banners.length > 1){
autoplayval= true;
} else {
autoplayval= false;
}
$('.anythingSlider')
.anythingSlider({
easing: "swing", // Anything other than "linear" or "swing" requires the easing plugin
autoPlay: autoplayval, // This turns off the entire FUNCTIONALY, not just if it starts running or not
startStopped: false, // If autoPlay is on, this can force it to start stopped
delay: 7000, // How long between slide transitions in AutoPlay mode
animationTime: 600, // How long the slide transition takes
hashTags: false, // Should links change the hashtag in the URL?
buildNavigation: true, // If true, builds and list of anchor links to link to each slide
pauseOnHover: true, // If true, and autoPlay is enabled, the show will pause on hover
startText: "Start", // Start text
stopText: "Stop", // Stop text
navigationFormatter: null // Details at the top of the file on this use (advanced use)
});
$('a.slide-link').show();
});
