Question

大家下午好。

我遇到了JavaScript / CSS / HTML问题，让我花点时间解释一下

我为我运行的网站编写了一个报价系统（http://www.liquidationmadeeasy.co.uk/quote.html）
我遵循了一个使用框架集的示例，以便为引用创建不同的阶段，但不导航到单独的页面。这很棒。
在每个字段集上，我引入了一个范围输入。我将执行计算并强制用户输入数值。
然后我按照另一个教程介绍了一个显示范围控件选定值的气泡。
当页面加载时，它会在每个范围控件的侧面绘制气泡。然而，当我导航到第二个框架集时，所有项目的气泡都在页面中间绘制（不在正确的位置）并且全部在彼此之上。
当用户从范围控制中选择一个值时，气泡会在正确的位置重新绘制。

当用户离开第一阶段时，我想自动重绘报价第二阶段的所有气泡。

我认为这是失败的，因为我重置了更改事件的范围输入值，该值仅在用户更改值时触发

有人能指出我正确的方向

这不是一个建议的解决方案，但我必须这样发布，所以我可以上传我的结果的截图。我逐字复制了你的HTML，CSS和JS（当然我必须适当地包装HTML），而且我没有遇到你描述的错误。我尝试使用两个不同的jQuery CDN文件：

https://code.jquery.com/jquery-2.1.1.min.js＆＃34;
https://code.jquery.com/jquery-1.11.1.min.js＆＃34;

以下是Firefox 29.0.1，Chrome 35，Safari 6.1.4和IE10中呈现的第二阶段＆＃34;资产价值＆＃34;的屏幕截图。前三个是Mac OS X 10.7.5，后者是在VirtualBox /上运行的Windows 8 VM上。订单是Firefox，Chrome，Safari，IE：

Firefox 29.0.1

Chrome 35

Safari 6.1.4

IE10

正如您所看到的，除了Firefox之外，渲染在某种程度上在所有浏览器中都被破坏了，但是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中似乎也运行良好：

Live site

您想发布用于测试的确切浏览器吗？

P.S。

与您的问题无关，但请注意，您的大多数HTML元素都有＆＃34;对于＆＃34;指向＆＃34; name＆＃34;的属性而不是＆＃34; id＆＃34;属性。请参阅<label> element in MDN documentation。
