Working Out UK Tax Weeks & Months

Sorry Javascript function is

<script>
function LZ(x) { return (x<0||x>=10?"":"0") + x }

function UKtaxWNstr(y, m, d) { var dd, fy = y // m = 1..12
  if (m*32+d<134) fy--
  dd = (Date.UTC(y, m-1, d) - Date.UTC(fy, 3, 6))/864e5
  return 'UK Revenue & Customs:' + ' Year ' + fy + ' week ' +
    LZ(Math.floor(dd/7)+1) + ' day ' + (dd%7+1) + ';' }

function UKtaxMNstr(y, m, d) { var yy = y, mm = m // m = 1..12
  if (d<6) mm--
  if (mm<4) { yy-- ; mm += 12 }
  return ' Year ' + yy + ' month ' + LZ(mm-3) + '.' }
 
  function TaxTest() { var D = new Date(),
  dy = D.getDate(), mo = D.getMonth()+1, yr = D.getFullYear()
  document.write('By TaxTest() : Today is ', D.YMDDstr(),
    ' ; thus it is :\n', UKtaxWNstr(yr, mo, dy),
    UKtaxMNstr(yr, mo, dy), '\nOddWkNo3(D, 4, 6) : ',
    ywkdStr(D=OddWkNo3(new Date(yr, mo-1, dy), 4, 6)),
    ";  OffWkNo3 : ", OffWkNo3(D, 4, 6).ISOlocaldateStr()  ) }
      
      
</script>

So are you looking for how to convert to CF or is the javascript code sufficient?

Yes i need to convert it to CF

Okay.

The way I would do it is using a cfc so you can preserve the smaller functions in the javascript block.

For example, the first one would look like

<cffunction name="LX">
   <cfargument name="x" type="numeric" required="true">
   <cfif x LT 0 OR x GTE 10>
        <cfset returnvalue = x>
   <cfelse>
       <cfset returnvalue = "0" + x>
    </cfif>
   <cfreturn returnvalue>
</cffunction>

However, the logic of that javascript doesn't really make sense to me.... but that is the direct conversion....

Then it would be called as :

<cfinvoke component="YourCFCName" method="LX" x="#variableGoesHere#" returnVariable="yourReturnVariable">
</cfinvoke>

Thanks mrichmon,  still having a few problems trying to work out the logic in CF to achieve the Tax Week & Tax Month ??

Okay I can help with that, but part that CANNOT be done is the document.write.  That is client side and CF is server side.

What do you want it to do instead?

mrichmon all i want to do is to have some type of formula that will determine the startdate and endate of a UK Tax week given a specified date. and store it in an array etc...

For Example trailblazzyr55 kindly helped me with a similar question

Basically what you need to do is to look at each function and slowly convert to CF one line at a time.

For example:

function UKtaxWNstr(y, m, d) { var dd, fy = y // m = 1..12
  if (m*32+d<134) fy--
  dd = (Date.UTC(y, m-1, d) - Date.UTC(fy, 3, 6))/864e5
  return 'UK Revenue & Customs:' + ' Year ' + fy + ' week ' +
    LZ(Math.floor(dd/7)+1) + ' day ' + (dd%7+1) + ';' }

First declare the function with the same name:
<cffunction name="UKtaxWNstr">

Next the incoming variables:
   <cfargument name="y" type="numeric" required="true">
   <cfargument name="m" type="numeric" required="true">
   <cfargument name="d" type="numeric" required="true">

Then the first line
<cfset fy = y>
Next line:
<cfif (m*32 + d) LT 134>
   <cfset fy = fy - 1>
</cfif>
etc.

If you run into a javascript function you don't know it is eady to see what it is doing on the web like the UTC function - here is a link:
http://www.devguru.com/Technologies/ecmascript/quickref/date.html
WHere it says:
UTC Method
This method returns the number of milliseconds from the date in a Date object since January 1, 1970 00:00:00 according to universal time. This is a static method of Date so the format is always Date.UTC() as opposed to objectName.UTC().

Syntax: Date.UTC(year, month, day [, hours, minutes, seconds, ms])

SO slowly working through will get the function converted.

jturkington, the last post I made does what you're looking to do, let me know if you need any more help...

Ahh sorry trailblazzyr55 thought i had closed this question....

yes the last post did the trick thanks again trailblazzyr55
