ColdFusion UDF For Converting Strings Into ASCII Characters
I needed a simple solution for converting strings such as email addresses, etc. into ASCII characters. So, I whipped up this little ColdFusion user-defined function to do just that and wanted to share it with anyone else who might need the same thing one day.
stringToAscii(str)
<cfscript>
function stringToAscii(str) {
var local = StructNew();
local.oldStr = '';
local.newStr = '';
if ( StructKeyExists(arguments, 'str') and IsSimpleValue(arguments.str) ) {
local.oldStr = arguments.str;
for ( local.i=1; local.i lte Len(arguments.str); local.i++ ) {
local.newStr = local.newStr & '&##' & Asc(Left(local.oldStr,1)) & ';';
local.oldStr = RemoveChars(local.oldStr,1,1);
};
};
return local.newStr;
};
</cfscript>
Here's some sample code for you to test with:
<cfparam name="form.txt" default="" />
<cfparam name="form.isSubmitted" default="false" />
<cfoutput>
<form method="post" enctype="application/x-www-form-urlencoded">
<p><label for="txt">Text:</label><br />
<input type="text" name="txt" id="txt" size="50" value="#form.txt#" /></p>
<p><input type="submit" value=" Encode It! " /></p>
<input type="hidden" name="isSubmitted" value="true" />
</form>
<cfif form.isSubmitted>
<h4>#stringToAscii(form.txt)#</h4>
<cfdump var="#stringToAscii(form.txt)#" /><br />
</cfif>
</cfoutput>
Enjoy!
Done. Thanks!
