范围输入的 JavaScript 位置问题

Question

大家下午好

我被一个 JavaScript/CSS/HTML 问题困住了，让我花点时间解释一下

1. 我为我运行的网站编写了一个报价系统 ( http://www.liquidationmadeeasy.co.uk/quote.html )

2. 我遵循了一个使用框架集的示例，以便为报价创建不同的阶段，但没有导航到单独的页面。效果很好。

3. 在每个字段集上，我引入了一个范围输入。我将执行一个计算，它会强制用户输入一个数值。

4. 然后我按照另一个教程介绍了一个显示范围控件的选定值的气泡。

5. 当页面加载时，它会在每个范围控件的一侧绘制气泡。然而，当我导航到第二个框架集时，所有元素的气泡都绘制在页面中间(不在正确的位置)并且全部在彼此之上。

6. 当用户从范围控件中选择一个值时，气泡会在正确的位置重新绘制。

我想在用户离开第一阶段时自动重绘报价第二阶段的所有气泡。

我假设这是失败的，因为我重置了仅在用户更改值时触发的更改事件的范围输入值

谁能给我指出正确的方向

这不是建议的解决方案，但我必须这样发布它，以便我可以上传我的结果的屏幕截图。我逐字复制了您的 HTML、CSS 和 JS(当然，我必须适本地包装 HTML)，但我没有遇到您描述的错误。我尝试使用两个不同的 jQuery CDN 文件:

• https://code.jquery.com/jquery-2.1.1.min.js "
• https://code.jquery.com/jquery-1.11.1.min.js "

以下是在 Firefox 29.0.1、Chrome 35、Safari 6.1.4 和 IE10 中呈现的第二阶段“ Assets 值(value)”的屏幕截图。前三个在 Mac OS X 10.7.5 上，后者在 VirtualBox/上运行的 Windows 8 VM 上。顺序是 Firefox、Chrome、Safari、IE:

如您所见，除 Firefox 外，所有浏览器的渲染都在某种程度上被破坏，但您描述的错误并未出现。我还注意到您链接到的网站:http://www.liquidationmadeeasy.co.uk/quote.html...在 Firefox 29 中似乎也能正常工作:

您想发布您用于测试的确切浏览器版本吗？

附言

与您的问题无关，但请注意，您的大多数 HTML 元素都有“for”属性，这些属性指向“name”属性而不是“id”属性。参见 <label> element in MDN documentation .
