定义与用法
The noscript element is used to define an alternate content (text) if a script is NOT executed.
noscript元素的用途就是当脚本无法执行的时候定义可用来做为替换的文字内容。
This tag is used for browsers that recognizes the <script> tag, but does not support the script in it.
这个标签是针对那些可以识别<script>标签，但却无法支持里面的脚本的浏览器。
在HTML和XHTML中的区别
NONE
无
提示与注意点
Note: If a browser supports scripting, it will not display the text in the noscript element.
注意：如果浏览器支持脚本，就不会显示在noscript里的文字了
Note: Browsers that do not recognize the <script> tag will display the tag's content as text on the page. To prevent the browser from doing this, you should hide the script in comment tags. An old browser (one that does not recognize the <script> tag) will ignore the comment and will not write the tag's content on the page, while a new browser will understand that the script should be executed, even if it is surrounded by comment tags!
注意：浏览器如果无法识别<script>标签，那么里面的内容会以文字的形式显示在页面上，如要避免出现这类情况，你可以在脚本外加上注释标签。
实例
