jQuery不在Chrome中运行，在FF中工作

jquery not running in chrome, works in ff

本文关键字：FF 工作 运行 不在 Chrome jQuery      更新时间：2023-09-26

我一直在用ff构建和测试，现在检查chrome。一切都很好，除了jquery不运行。我似乎记得以前遇到过这个问题，但我不记得如何解决它。

我正在一个 rails 应用程序中工作，这是我想运行的脚本：

编辑

页面加载时会出现警报，但就绪函数永远不会执行。 所以希望这能稍微缩小问题的范围。

<script>
alert("hi")
$(document).ready(function () {
var theButton = $('#back-to-top');
var theButtonWidthOverTwo = theButton.width()/2;
theButton.css('top', $(window).height()-60);
theButton.css('right', $(window).width()/2-theButtonWidthOverTwo);
theButton.on("click", function() {
    $('html, body').animate({scrollTop: 0}, "fast");
});
$(window).resize(function () {
    theButton.css('top', $(window).height()-60);
    theButton.css('right', $(window).width()/2-theButtonWidthOverTwo);
});
$("#club-posts-table").tablesorter();
});
</script>

表排序器来自同名插件（作为 gem 安装）。

还有一个带有简短功能的按钮：

<button id="back-to-top" class="pink" onclick="$('html, body').animate({ scrollTop: 0 }, 'fast');" style="position: fixed;bottom:0;z-index: 10; width: 240px;opacity: 0.3;">Back To Top</button>

所以基本上这些东西都没有在chrome中运行。我还尝试将脚本移动到实际的 js 文件中，以便它成为资产管道的一部分，但它不起作用。撇开表排序器不谈，ready函数和按钮中的代码不需要任何帮助来运行。

编辑 2 整个文件：

<div id="container-new-admin">

  <button class="pink" onclick="window.location='<%= session[:back_button_url]%>';" style="width:200px;position:relative;margin:10px auto">Back</button>
  <% if @posts_array != nil %>
  <h1 style="text-align: center">All Posts By Members of <%= get_club_name_by_id %></h1>
  <table id="club-posts-table" class="tablesorter">
    <thead>
    <td>Poster</td>
    <td>Thumbnail</td>
    <td>Content</td>
    <td>Num Comments</td>
    <td>Num Elevates</td>
    <td>Date Posted</td>
    </thead>
    <tbody>
    <% @posts_array.each do |p| %>
        <tr>
          <td><%= p.user.username %></td>
          <td><a href="/post/<%= p.id %>" target="_blank"><%= load_image_only_if_exists(p) %></a></td>
          <td><%= p.post_text %></td>
          <td><%= p.comments.length %></td>
          <td><%= p.post_elevations.length %></td>
          <td><%= p.created_at.strftime("%m/%d/%Y") %></td>
        </tr>
    <% end %>
    </tbody>
  </table>
  <% else %>
  <h1 style="text-align: center">Try again, using a club id this time...</h1>
  <% end %>
  <button id="back-to-top" class="pink">Back To Top</button>
</div>
<script>
****see above****
</script

我认为只用css这样做会更容易。请在此jsFiddle中找到演示。

onclick 处理程序也在演示中工作，但我认为最好在脚本中添加处理程序（如评论中建议的那样）。

//$(function(){$("#club-posts-table").tablesorter();});
$(document).ready(function () {
    var theButton = $('#back-to-top');
    
    /* works but css is even simpler - one line in css with :hover
    var show = function() {
        $(this).css('opacity','1.0');
    };
    var hide = function() {
        $(this).css('opacity','0.3')
    };
    
    // hover(inHandler, outHandler)
    theButton.hover(show, hide);
    */
    
    /* works but hover is easier
    theButton.on("mouseover", function() {
        theButton.css('opacity','1.0')
    });
    
    theButton.on("mouseout", function() {
        theButton.css('opacity','0.3')
    });*/
    
    theButton.click(function() {
        $('html, body').animate({ scrollTop: 0 }, 'fast');
    });
});
button {

}
#back-to-top {
    z-index: 10; 
    width: 240px;
    max-width: 100%;   /* Make it fit window if under 500px */ 
    opacity: 0.3;
}
#back-to-top:hover {
    opacity: 1.0;
 
}
.footer {
    position: fixed;
    /*background-color: blue;*/
    text-align: center;

好的，所以对于遇到这种情况的任何其他人来说，这归结为对高度的一些奇怪的解释，我不确定为什么，但 chrome 似乎认为 $（'body'）.scrollTop 值始终为 0。

当我检查身体并取消检查它的高度设置为 100% 的两个地方时，一切正常。
