This is what I have so far..
<cffunction name="createWordList" returntype="array">
<cfargument name="wordArray" required="yes" type="array" />
<cfargument name="strbase" default="" required="yes" type="string" />
<cfargument name="remainingchars" default="" required="yes"
type="string" />
<cfset var j = 1 />
<cfset var currchar = "" />
<cfscript>
if(len(remainingchars) eq 1) {
wordArray[ArrayLen(wordArray)+1] = strbase &
mid(remainingchars,1,1);
} else {
for (j = 1; j lt len(remainingchars); j=j+1) {
currchar = mid(remainingchars,j,1);
if(find(currchar,remainingchars,j) eq j) {
arrayappend(wordArray,
mid(remainingchars,1,j) &
mid(remainingchars,j+1,len(remainingchars)));
//createWordList(wordArray, strbase &
mid(remainingchars,1,j), mid(remainingchars,1,j) &
mid(remainingchars,j+1,len(remainingchars)));
//wordArray = createWordList(wordArray,
strbase + remainingchars.charAt(j), remainingchars.substring(0, j) +
remainingchars.substring(j+1, remainingchars.length)); //recursive
call
}
}
}
</cfscript>
<cfreturn wordArray />
</cffunction>
The specific part I'm having problems with is
//wordArray = createWordList(wordArray,
strbase + remainingchars.charAt(j), remainingchars.substring(0, j) +
remainingchars.substring(j+1, remainingchars.length)); //recursive
call
That's how it's done in Javascript.. I just can't convert it to ColdFusion..
