Question

我有一个rails应用程序，我正在尝试添加缩略图滚动条。它打印div，但js不起作用。这是文件：

<div id="tS2" class="jThumbnailScroller">
    <div class="jTscrollerContainer">
        <div class="jTscroller">
          <% @illustrations.each do |illustration| %>
              <% if illustration.aws_image_thumbnail_url %>
                <%= link_to image_tag(illustration.aws_image_thumbnail_url, :title => illustration.name), illustration %>
              <% else %>
                <%= link_to image_tag(illustration.image.url(:thumb), :title => illustration.name), illustration %>
              <% end %>
          <% end %>
        </div>
    </div>

</div>

<script>
jQuery.noConflict();
(function($){
window.onload=function(){
    $("#tS2").thumbnailScroller({
        scrollerType:"hoverPrecise",
        scrollerOrientation:"horizontal",
        scrollSpeed:2,
        scrollEasing:"easeOutCirc",
        scrollEasingAmount:600,
        acceleration:4,
        scrollSpeed:800,
        noScrollCenterSpace:10,
        autoScrolling:0,
        autoScrollingSpeed:2000,
        autoScrollingEasing:"easeInOutQuad",
        autoScrollingDelay:500
    });
}
})(jQuery);
</script>

这是控制台中的错误：

Uncaught TypeError: Object [object Object] has no method 'thumbnailScroller' 138:168
window.onload 138:168
window.onload

以下是thumbnailScroller中的jquery.thumbnailScroller.js方法：

(function($){  
 $.fn.thumbnailScroller=function(options){  
    var defaults={ //default options
        scrollerType:"hoverPrecise", //values: "hoverPrecise", "hoverAccelerate", "clickButtons"
        scrollerOrientation:"horizontal", //values: "horizontal", "vertical"
        scrollEasing:"easeOutCirc", //easing type
        scrollEasingAmount:800, //value: milliseconds
        acceleration:2, //value: integer
        scrollSpeed:600, //value: milliseconds
        noScrollCenterSpace:0, //value: pixels
        autoScrolling:0, //value: integer
        autoScrollingSpeed:8000, //value: milliseconds
        autoScrollingEasing:"easeInOutQuad", //easing type
        autoScrollingDelay:2500 //value: milliseconds
    };

在这里你可以看到js文件被加载到rails app（chrome developmnet tools'resources'选项卡输出：

有谁知道为什么这种方法不可用？

好的，我尝试在我的培训应用上使用缩略图滚动jQuery插件并成功。

首先，从您的应用中删除jquery-ui-1.8.13.custom.min.js

确保gem文件中的这个gem

gem 'jquery-rails'
gem 'jquery-ui-rails'

删除Gemfile.lock并运行bundle install

确保application.js看起来很像：

//= require jquery
//= require jquery_ujs
//= require jquery.ui.all

尝试使用方法jquery缩略图，将其放在head标记

之间

  <script type="text/javascript">
  $(function () {
    $("#tS2").thumbnailScroller({
        scrollerType:"hoverPrecise",
        scrollerOrientation:"horizontal",
        scrollSpeed:2,
        scrollEasing:"easeOutCirc",
        scrollEasingAmount:600,
        acceleration:4,
        scrollSpeed:800,
        noScrollCenterSpace:10,
        autoScrolling:0,
        autoScrollingSpeed:2000,
        autoScrollingEasing:"easeInOutQuad",
        autoScrollingDelay:500
    });
});</script>

控制台状态方法不可用，但它似乎应该是
