flash is a powerful web technology that achieves a high level of visual impact from the graphical point of view. unfortunately, it is widely misused in web design. there are still many problems with flash, especially related to usability and search engine behaviour; we need to thoroughly understand what those problems are before we decide to use flash for our site.
flash是一种功能坚强雄厚的网站预设技术,从绘图学观点来说,flash的确能萌生高水准的视物感觉影响力。不过,众多网站乱用flash技术,以致网站显露出来某些运行问题。在可用性以及与搜索引擎网站的关系方面,flash还是存在自身的欠缺,所以在使用flash曾经,我们需求首先理解它有可能导发的几个问题。
as with any business decision, it all boils down to understanding what our target audience wants.
在做不论什么业务决策之前,都务必思索问题目的客户的需求。
if you want to make a big impression from a graphical point of view, flash is definitely a good approach. however, concrete evidence still points to the fact that most web users utilize the web to find information, and what they regard most important is:
从绘图学观点来说,假如期望网站给客户留下深刻的印象,运用flash就是一种好办法。不过,众多实事证实:大多用户只是利用网站搜索信息,他们觉得网站最关紧的是:
a) quality of content
内部实质意义品质
b) ease of navigation, and
简单方便的导航系统,以及
c) speed.

users also consider the web a highly interactive medium: they are unlikely to watch a computer screen for long periods of time without giving some sort of input.
同时,用户觉得网络是一种相互作用电视台:它们不会长时间浏览电脑荧幕,肯定要输入有关内部实质意义。
flash technology presents several problems that go against the way most people use the web. for example:
flash技术会导发几个问题,在网站运行中,会给大部分数用户带来麻烦。
 bandwidth and load time constrains: sites designed with flash take a long time to download and consume vast amounts of bandwidth. not all users have a broadband connection. flash forces users with dial-up connections to spend valuable time watching the load bar, instead of getting to the information they want, fast.
带宽与下载时间的限止:用flash技术预设的网站,占用数量多的宽带空间,下载速度很慢。一定记取:并不是全部用户都利用宽带上网。在登录flash网站时,电话拨号上网的用户务必消耗的钱珍贵时间特意的看下载条,而不可以迅速取得需求的信息。
 usability constrains: when you navigate a flash site designed with a older version, the back button does not work: instead of taking you to the previous screen, it will get you out of the flash site. also, the standard colors for visited and unvisited links will not work, and users have no control over the text size they want to use.
可用性限止:用老版本flash预设的网站,退回键没管用用:点击退回键会使你退出flash网站,而不是回返上一层网页。同时,链接以及非链接的标准颜色会发生变更,况且用户须扼制需求利用的文本尺寸。
 furthermore, many times flash sites go against the interactive nature of the web. since flash technology favors a "presentation style" approach that resembles television, users are many times reduced to mere observers that get bored after a while, no matter how good the graphics look.
并且,flash 常常带来网站交互问题。因为flash支持大致相似于电视的闪现标准样式办法,所以用户常常作为观赏者显露出来。无论银幕多么精致美好,过时期,用户便会对内部实质意义萌生厌倦。
 search engine constrains: although large search engines like google now have some flash indexing capabilities, these are still very limited. you will definetely have a hard time achieving high rankings with a flash site. one option around this problem is to design a second, search-engine-friendly html version of your site. this, though, usually represents an unnecessary expense in both time and money, since in most cases the html version alone will get the job done.
搜索引擎网站的限止:尽管像google这么的大型搜索引擎网站,如今具有了对flash做引得的有经验,但搜索内部实质意义还是十分有限,所以flash网站不会在搜索引擎网站中取得好的名次。解决这个问题的一种办法是:利用html预设网站,这么的网站会有一个好的名次。利用flash预设网站,会增加不不可缺少的货币和时间费用,实际上 html网页就可以完成全部的功能。
although few, there are some instances when flash technology can actually be helpful:
尽管flash存在以上几个欠缺,但它一样有自个儿的长处:
a) when you need to show a presentation, for example a demo of your product.
可以使用flash,展览内部实质意义,譬如:展览企业样品。
b) to develop interactive games, like those found on sites for kids like sesame street, nickelodeum, or yahoo! games.
研发相互作用游戏时,可以使用flash,譬如:sesame street、 nickelodeum, 、yahoo! games等孩童游戏,都运用了flash
c) when you want to dress up a minimalist site. in this case, a small flash animation or banner embedded in an html document will not consume excessive bandwidth, will load fast, and will enhance the appearance of a bare-bones site.
当你想扮饰简约网站时,你可以使用小规模flash动画,还是在html文件中插进去标语性质的flash,这么不会占用过多的宽带空间,下载速度很快,况且可以增加网站的观赏性。
although macromedia (the company that developed flash) is actively working to improve flash’s usability problems (they even formed a partnership with usability guru jakob nielsen in 2002), issues like slow downloads and search engine un-friendliness still remain a problem. until these issues are addressed and solved, you will be better-off by only using flash in those rare instances when it actually enhances the value of your content.
尽管,macromedia(flash研发企业)正在积极采取办法改善flash的可用性问题(甚至于在2002年组成以网站可用性研讨资深专家jakob nielsen为首的办公组,专门研讨这个问题),不过下载速度慢、搜索引擎网站对其不友善的问题,还是没有解决。在这些个问题目解释题决往后,假如利用flash可以增加网站价值(少量事情状况),那你可以使用。
