如果只有一个<li>使用anythingSlider(jQuery插件),如何停止滑动?

我目前正在使用 anythingSlider 插件,除了只有一个插件外,它工作完全正常 <li> .

这个 <李> 是从数据库生成的,所以有时只有一个。

然而,anythingSlider插件仍然试图通过 <李>

如果只有一种方法,有人知道有什么方法可以阻止它滑行吗 <李> ?

你好

if (banners<1) {
    .anythingSlider({
        startStopped: true,
        buildNavigation: false
        });
    }

“banners”是我调用的变量。

救命啊?!

    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
    }
