使用 wmode=“transparent"、“opaque"或“window"之间的区别对于网页上的嵌入对象 [英] differences between using wmode="transparent", "opaque", or "window" for an embedded object on a webpage
问题描述
当使用 和 标记嵌入 Flash 对象时，有一个名为 wmode 的属性.似乎在大多数情况下，wmode="transparent" 与 wmode="opaque" 相同，因为 Flash 实际上没有任何透明颜色，因此将显示底部 HTML 元素.因此，opaque 应该比 transparent 更快，因为它需要较少的透明度处理，但大多数时候我看到 Flash 对象嵌入了 transparent 而不是 opaque.
when embedding a Flash object with the <object> and <embed> tag, there is an attribute called wmode. It seems that most of the time, wmode="transparent" is the same as wmode="opaque" as the Flash doesn't actually have any transparent color so that the bottom HTML element is to be shown. As a result, opaque should be faster than transparent since it requires less processing for transparency, yet most of the time i see Flash object embedded with transparent instead of opaque.
opaque 以便其他 HTML 元素不会被 Flash 对象覆盖(例如弹出额外子菜单的菜单项不会被 Flash 对象覆盖)Flash 对象).
opaque is needed so that other HTML element won't be covered up by the Flash object (such as a menu item that pops up an extra sub-menu won't be covered up by the Flash object).
顺便说一下，wmode 的opaque、transparent 和window 有正式的文档吗?我只能找到描述它的博客，但找不到正式的文档.谢谢.
By the way, is there formal documentation for wmode's opaque, transparent, and window? I was only able to find blogs that describe it but not the formal documentation. thanks.
