CFScript

CFScript is an extension of CFML on the ColdFusion platform. CFScript resembles JavaScript. Some ColdFusion developers prefer it since it has less visual and typographical overhead than ordinary CFML; only the actual changes are represented in the code (whereas normal CFML would involve CFSET tags at every line).

Usage

All CFScript code must be contained within a CFScript tag pair, as follows:

<cfscript>
    xParam = 115;
    yParam = 200;
    color = 'FFCC99';
</cfscript>

While many ColdFusion tags have exact CFScript analogies, there are quite a few tags that do not. These include both complex tags that would be difficult to duplicate and simple tags that are easy to imitate (using ColdFusion UDF's):

Complex:

<cfquery>
<cffile>
<cfdirectory>

Simple:

<cfdump>
<cfthrow>

While there may not be direct substitutions for all tags, it is often still possible to achieve the results of a tag in script, but via a different syntax. For example this is how to get a query into a variable in CFSCRIPT without writing a UDF:

<cfscript>
  qGetData = new Query(); 
  qGetData .setDataSource('#APPLICATION.datasource#');
  qGetData .setSQL('SELECT column1, column2 FROM table WHERE 1'); 
  qDateResult = qGetData .Execute().getResult();
</cfscript>

Syntax

Since Coldfusion 8 cfscript has supported syntax abbreviations that are common in many other programming languages, such as "++", "<=" and "+=".
