CFScript is an extension of CFML on the ColdFusion platform. CFScript resembles JavaScript but is simpler to use. This presentation talks about Colon separators in structures (key:value pairs), Use of FOR-IN loop over queries and Java arrays, Use of ArrayEach() And StructEach(), New tag equivalents in script statements(setting, cookie) & New tag equivalents as functions(invoke) etc.

1. ColdFusion10: CFScript
Enhancements

2. WHAT’S NEW IN CF10?
•
•
•
•
Colon separators in structures (key:value pairs).
Use of FOR-IN loop over queries and Java arrays.
Use of ArrayEach() And StructEach().
New tag equivalents in script statements(setting,
cookie)
• New tag equivalents as functions(invoke)
• New tag equivalents as CFCs(collection, index,
search)

3. colon separators in structures
(key:value pairs)
We can now define the key:value pairs within a structure
using colon (:) separator when defining them with implicit
structure notation.
Ex: <cfscript>
student = {firstname:"abc", lastname:"def",
grades:[12,23,45]};
</cfscript>
Also supported:
• <cfset student = {firstName:"Jane", lastName:"Doe",
grades:[77, 84, 91]}>
• Not supported: <cfset name:”Jane”> or name:”Jane”;

4. Looping Over Queries and Java Arrays
Using For-In Loop
• ColdFusion has long been able to use the for-in
statement to loop over structures
• And ColdFusion 9.0.1 added the ability to loop over
CFML arrays
• Now can loop over query results.
Various Java methods return java arrays
• Can now loop over those in CFSCRIPT

5. Use of ArrayEach() And StructEach()
• “ArrayEach” is used to loop over an array object.
• The Handle Function can have each element of
the array during looping.
• We can apply our business logic inside the
handler function .
• We can write the handler function as inline
function or a named function which we can reuse
in multiple cases.
• Similarly in StructEach, we can loop over a
structure elements.

6. New tag equivalents in script
statements(setting, cookie)
• CFSETTING can be used to set requesttimeout,
enablecfoutputonly, showdebugoutput.
• Especially valuable for use in cfscript-based
application.cfc.
• Now it can set requesttimeout=0
Turns off any requesttimeout set in Admin or
previously in request

7. Cookie
• We could always set as cookie.name=“value”, but
now can set all properties
Example:
<cfscript>
cookie.firstname = {value="Charlie",expires="10"};
cookie.firstname = {value:"Charlie",expires:"10"};
</cfscript>
• Properties that can be set: value, expires, domain,
path, secure, and httponly.

8. New tag equivalents as
functions(invoke)
• We can now invoke CFC/web service methods using
invoke().
• Example: <cfscript>
retval=invoke("demo","helloWorld");
</cfscript>
• Also we can pass arguments.
<cfscript>
retval=invoke("demo","helloFriend",{name="Charlie"});
</cfscript>

9. • Also We can use instances here.
Example:
helloInstance=createobject("component","demo");
retval=invoke(helloInstance,"helloWorld");
• We can invoke a web service using cfscript.
<cfscript>
tempSvc=createobject("webservice","http://wsf.cdyne.
com/WeatherWS/Weather.asmx?WSDL");
retval=invoke(tempSvc,"GetCityWeatherByZIP",{zip="30
005"});
</cfscript>

10. New tag equivalents as
CFCs(collection, index, search)
• Can create a Solr collection in a directory anywhere
on server.
• Can create and delete collections inside cfscript.
• Also can map, optimize, and categoryList (New for
Solr)

11. Index
• Now we can put data into the collection using cfindex,
which is now possible inside cfscript.
Example: m=new index();
m.update(collection="merchandise",query=merch,key="me
rchid",type="custom",title="merchname",body="merchd
escription");
Also we can use.
• delete (to remove one or more items from the index)
• purge (to remove all items from the index)
• ColdFusion 10 adds other CFINDEX actions: abort,
deltaimport, fullimport, and status

12. Search
• CFSEARCH is used to search Solr collections which is
now possible inside cfscript.
Example: <cfscript>
merch=new
search().search(collection="merchandise",criteria="ti
tle:ColdFusion",maxRows=10);
writeDump(var=merch.getresult().name,show="score,ti
tle,summary");
</cfscript>
