Question

我正在创建一个wordpress主题但继续遇到标题中提到的错误。在过去的几天里，我一直试图找出为什么没有看到这个功能，但似乎无法找到解决方案。

在front-page.php中。我在谷歌地图中的标记点击事件中进行了以下函数调用。

$.fn.snd_slider.external_move_to( marker_order );

哪个函数位于我的main.js文件中。我为代码的长度道歉，但我认为有必要包括更多，以防我忽略了一些事情：

(function($){
    $.fn.snd_slider = function( options ) {
        var settings = $.extend( {
            slide                   : '.snd-slide',                 // slide class
            arrows                  : '.snd-slider-arrows',         // arrows container class
            prev_arrow              : '.snd-arrow-prev',            // left arrow class
            next_arrow              : '.snd-arrow-next',            // right arrow class
            controls                : '.snd-controllers a',         // control selector
            control_active_class    : 'snd-active-control',         // active control class name
            previous_text           : 'Previous',                   // previous arrow text
            next_text               : 'Next',                       // next arrow text

非常感谢任何帮助！

我发现了我的问题的答案。这有点令人尴尬，但我意识到我没有调用返回我试图访问的函数的函数。错误是为了学习，对吧？

未捕获的TypeError：$ .fn.snd_slider.external_move_to不是函数
