i need to transform this function to javascript

<SCRIPT language=VBscript>
	function tt(str)
		tt = trim(str)
	end function
	
	function IsD(str)
		for i = 1 to len(str) 
			if Asc(mid(str,i,1))<48 or Asc(mid(str,i,1))>57 then
				checkD = false
				exit function
			end if
		next
		checkD = true
	end function
	
	function IsDC(str)
		for i = 1 to len(str)
			dd = Asc(mid(str,i,1))
			if dd<48 or (dd>57 and dd<65) or (dd>90 and dd<97) or dd>122 then
				IsDC = false
				exit function
			end if
		next
		IsDC = true
	end function
</SCRIPT>

plz if someone can do it, i would be very happy

thx

Javascript does not have a trim function like in vbscript. use the following function to remove the leading and trailing blank spaces from the string:

function alltrim(s)
{
// Returns string with leading and trailing blanks removed.

// Is s empty?
if (isEmpty(s))
return "";
var i, n;

// First find position of first nonblank character in string
for (i = 0; s.charAt(i) == ' ' && i <= s.length;i++);

// Search from end of string, find position of last nonblank character in string
for (n = s.length; s.charAt(n-1) == ' ' && n >= 0;n--);

return s.substring(i,n);
}

Now your tt function

function tt(str){
return alltrim(str);
}

Now IsD function

function IsD(str){
var blnCheckD = false;
var strText = new String(alltrim(str));
if(strText != ''){
for(var i=0; i<strText.length; i++){
if(strText.charCodeAt(i)< 48 || strText.charCodeAt(i) > 57){
blnCheckD = true;
break;
}
}
}

return blnCheckD
}

Now IsDC function

function IsDC(str){
var blnCheckD = true;
var strText = new String(alltrim(str));
if(strText != ''){
for(var i=0; i<strText.length; i++){
cText = strText.charCodeAt(i);
if(cText < 48 || (cText > 57 && cText < 65) || (cText > 90 || cText < 97) || cText > 122){
blnCheckD = false;
break;
}
}
}

return blnCheckD;
}


I have not tested the conversion, check it and if you get into some error post the error and i will look into it then.

Sorry, in alltrim function i am using isEmpty function and forgot to post it. Here is the function:

function isEmpty(s)
{
return ((s == null) || (s.length == 0))
}
