Another Hints Bug

[+BillP3rd]

When a hint contains a web link in the form [http://www.somesite.com] it's helpfully converted into a live web link. To demonstrate:

 

[

http://en.wikipedia.org/wiki/Book_cipher

]'>

http://en.wikipedia.org/wiki/Book_cipher

]

results in

(

]visit link

)

No. the extra ']' in the result isn't a typo. That's what's coming from geocaching.com. After some experimentation I've learned:

If there's interest by Groundspeak I'll be happy to fix the decrypting problem with the link (It should take about 10 minutes to write and test). The presentation problem appears to be on the server side.

This code fixes the decrypting problem (both with the anchor tag AND the line breaking problem).

 

function convertROTStringWithBrackets(s) {
if (!rot13array)
rot13array=createROT13array();

var sChar = "";
var sOutput = "";
var bDecrypt = true;

for( i = 0; i < s.length; i++) {
sChar = s.charAt(i);

// **** START OF FIX ****
// check for break and anchor tags
if ( i < (s.length - 4) ) {
	if ( s.toLowerCase().substr( i, 4 ) == "<br>" ) {		// is line break
		sOutput += "<br>";
		i += 3;
		continue;
	}
	else if ( s.toLowerCase().substr( i, 3 ) == "<a " ) {	// start of anchor
		bDecrypt = false;
		sOutput += "<a ";
		i += 2;
		continue;
	}
	else if ( s.toLowerCase().substr( i, 4 ) == "</a>" ) {	// end of anchor
		bDecrypt = true;
		sOutput += "</a>";
		i += 3;
		continue;
	}
}
// **** END OF FIX ****

// ignore any text enclosed in [ ] brackets
if (sChar == "[")
	bDecrypt = false;
else if (sChar == "]")
	bDecrypt = true;
else if ( (sChar == " ") || (sChar == "&dhbg;") ) {
	// do nothing
}
else {
	if (bDecrypt)
		sChar = convertROT13Char(sChar);
}

	sOutput += sChar;
}

return sOutput;
}
