jquery - 未捕获的 TypeError : $(. ..).responsiveSlides 不是函数

Question

我有一个 joomla 网站。我使用了一个模板来使用。 主页幻灯片不起作用。 >检查元素>控制台显示错误:

Uncaught TypeError: $(...).responsiveSlides is not a function

我相信它指的是我认为的这段代码:

slideshow.php:

<script>
// You can also use "$(window).load(function() {"
$(function () {
  $("#slider4").responsiveSlides({
    auto: true,
    pager: false,
    nav: true,
    speed: 500,
    namespace: "callbacks",
    before: function () {
      $('.events').append("<li>before event fired.</li>");
    },
    after: function () {
      $('.events').append("<li>after event fired.</li>");
    }
  });

});
</script>

<?php     
 $slide1    =   htmlspecialchars($this->params->get('slide1')); 
 $slide2    =   htmlspecialchars($this->params->get('slide2')); 
 $slide3    =   htmlspecialchars($this->params->get('slide3'));  
 $slide4    =   htmlspecialchars($this->params->get('slide4')); 
 $slide5    =   htmlspecialchars($this->params->get('slide5')); 
 $slide6    =   htmlspecialchars($this->params->get('slide6')); 
 $slide7    =   htmlspecialchars($this->params->get('slide7'));  
 $slide8    =   htmlspecialchars($this->params->get('slide8'));

 $NumberOfSlides    =   htmlspecialchars($this->params->get('NumberOfSlides'));
?> 


<div class="callbacks_container">
  <ul class="rslides" id="slider4">

  </ul>

我认为这就是问题的根源。我对 jquery 不熟悉。我需要更改什么才能使其正常工作？

这是它应该引用的js函数:

Answer 1

而不是

<script>
// You can also use "$(window).load(function() {"
$(function () {

你可以使用

<script>
// You can also use "$(window).load(function() {"
jQuery(function ($) {

希望这有帮助
