Insert a Script into HTML Page
在HTML页中插入脚本

A script in HTML is defined with the <script> tag. Note that you will have to use the type attribute to specify the scripting language.
在HTML中脚本是用<script>标签定义的.注意得用type属性来指明所用的脚本语言.

<html>
<head>

</head>
<body>
<script type="text/javascript">
document.write("Hello World!")
</script>
</body>
</html>

The script above will produce this output:
上面的脚本会生成:

Hello World!

How to Handle Older Browsers
怎样处理老的浏览器

A browser that does not recognize the <script> tag at all, will display the <script> 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 (that does not recognize the <script> tag) will ignore the comment and it 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.
一些浏览器不支持<srcipt>标签,会将里面的内容以文本的形式显示出来,为了防止这样,你应该将脚本内容用注释的方法来进行隐藏.

Example
例子

JavaScript:
<script type="text/javascript">
<!--
document.write("Hello World!")
//-->
</script>

VBScript:
<script type="text/vbscript">
<!--
document.write("Hello World!")
'-->
</script>

 

The <noscript> Tag
<noscript>标签

In addition to hiding the script inside a comment, you can also add a <noscript> tag.
除在注释里隐藏脚本,你还可以添加一个<noscript>标签.

The <noscript> tag is used to define an alternate text if a script is NOT executed. This tag is used for browsers that recognize the <script> tag, but do not support the script inside, so these browsers will display the text inside the <noscript> tag instead. However, if a browser supports the script inside the <script> tag it will ignore the <noscript> tag.
<noscript>标签用来给不能执行的脚本来定义说明文字.这个标签是为那些不能支持<script>标签的浏览器而准备的,不执行脚本而是显示<noscript> 里的文字.

Example
例子

JavaScript:
<script type="text/javascript">
<!--
document.write("Hello World!")
//-->
</script>
<noscript>Your browser does not support JavaScript!</noscript>

VBScript:
<script type="text/vbscript">
<!--
document.write("Hello World!")
'-->
</script>
<noscript>Your browser does not support VBScript!</noscript>
