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.

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. xParam = 115; yParam = 200; color = 'FFCC99'; A simple example of a function: function Sum(a, b) { var sum = a + b; return sum; } A simple example of a component in CFScript, containing two functions: component { public void function foo() { WriteOutput("Method foo() called "); } public function getString() { var x = "hello"; return x; } } ColdFusion 11, Railo 4.1+, and Lucee 4.5+ both do their best to fully support cf tags in CFScript. 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: qGetData = new Query(); qGetData.setDataSource('#Application.datasource#'); qGetData.setSQL('SELECT column1, column2 FROM table WHERE 1'); qDateResult = qGetData.Execute().getResult(); Since ColdFusion 8, CFScript has supported syntax abbreviations that are common in many other programming languages, such as "++", " // This is a single-line comment. // This is a second single-line comment. /* This is a multiline comment. You do not need to start each line with a comment indicator. This line is the last line in the comment. */ try { throw(message="Oops", detail="xyz"); } catch (any e) { WriteOutput("Error: " & e.message); rethrow; } finally { WriteOutput("I run even if no error"); } switch (car) { case "Nissan": WriteOutput("I own a Nissan"); break; case "Toyota": WriteOutput("I own a Toyota"); break; default: WriteOutput("I'm exotic"); } for (i=1; i struct = StructNew(); struct.one = "1"; struct.two = "2"; for (key in struct) { WriteOutput(key); } //OUTPUTS onetwo x = 0; while (x x = 0; do { x = x + 1; WriteOutput(x); } while (x for (item in array) { doSomething(item); }
