我想获取（新建和浏览）的选择页面，以显示分类，产品，组件和cf_subcomponent的下拉框。 并根据前一个字段的选择填充有效的选择选项。
我不知道我为bugzilla得到了正确的变量，还认为我的JS不正确。
我想在下一页的URI中结束这个 -
http://bugs/buglist.cgi?product=<product1>&component=<component1>&cf_subcomponent=<subcomponent1>
到目前为止我所拥有的是什么

我最终为每个选项编写了一个完整的JavaScript，但是我找不到其他方法。
正如您可能看到这是一个示例，我在树上有其他组件，但这应该告诉您如何操作。
