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
fade_speed : 500, // fade effect speed
use_arrows : true, // use arrows?
use_controls : true, // use controls?
manual_arrows : '', // html code for custom arrows
append_controls_to : '', // controls are appended to the slider element by default, here you can specify the element it should append to
controls_class : 'snd-controllers', // controls container class name
slideshow : false, // automattic animation?
slideshow_speed : 7000, // automattic animation speed
on_slide_changing : function(){}, // callback function that runs when a slide changes
on_slide_change_end : function(){} // callback function that runs when a slide changes
}, options );
return this.each( function() {
var $snd_slider = $(this),
$snd_slide = $snd_slider.find( settings.slide ),
snd_slides_number = $snd_slide.length,
snd_fade_speed = settings.fade_speed,
snd_active_slide = 0,
$snd_slider_arrows,

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？
