<cfscript>is a Coldfusion tag for using the Coldfusion scripting language(aka CFScript). If you want to use Javascript, open a <script>tag like you would normally in HTML. You'll probably want to make sure it's inside a <cfoutput>tag if you want to use Coldfusion values within your javascript.
<cfscript>是用于使用Coldfusion 脚本语言（又名 CFScript）的 Coldfusion 标签。如果您想使用 Javascript，请<script>像通常在 HTML 中一样打开一个标签。<cfoutput>如果您想在您的 javascript 中使用 Coldfusion 值，您可能需要确保它在标签内。
<cfset right_now = Now()>
<cfoutput>
<script type="text/javascript">
alert('#right_now#'); // don't forget you need to put quotes around strings in JS
</script>
</cfoutput>

You don't need to even use cfscript for this specific need. You could, for instance, do this:
您甚至不需要使用 cfscript 来满足此特定需求。例如，您可以这样做：
<script type="text/javascript">
var currtime = new Date();
alert(currtime);
</script>

... Also a point to remember, you can't directly output HTML from within a <cfscript>tag. You can however get around this by calling a function from within a <cfscript>tag that can output the data for you.
... 还有一点要记住，您不能直接从<cfscript>标签内输出 HTML 。但是，您可以通过从<cfscript>可以为您输出数据的标记中调用函数来解决此问题。

Always remember the coldfusion begins and ends before anythingelse is executed: html, javaScript, sql, etc., so the javascript is getting an already formed code, which is CF instead of being hard coded.
永远记住，在执行其他任何东西之前，coldfusion 开始和结束：html、javaScript、sql 等，所以 javascript 得到一个已经形成的代码，这是 CF 而不是硬编码。
