How can I convert ColdFusion variables into JavaScript variables?

Use the toScript() function to create JavaScript variables from a ColdFusion variable. This function can convert ColdFusion strings, numbers, arrays, structures, and queries to JavaScript syntax that defines equivalent variables and values.

<cfset thisString="hello world">
<script type="text/javascript" language="JavaScript">
<cfoutput>
var #toScript(thisString, "jsVar")#;
</cfoutput>
</script>

When ColdFusion runs this code, it sends the following to the client:

<script type="text/javascript" language="JavaScript">
var jsVar = "hello world";
</script>

You can also do this using cfwddx to convert a coldfusion object into a javascript object which is handy for things like structs.

Don't forget the new toScript() function in CFMX 7. It allows you to assign the value of a CF variable to a JavaScript (or ActionScript) variable. It does this for JavaScript through the magic of WDDX, but it's a lot simpler than using the WDDX libraries to get the same result.
