Hi Taha,
Thanks for the response. The latter suggestion doesn't work for me,
these urls are external urls input by the user. I tried the first
suggestion but it does not work. Not sure exactly what all the issues
are, but I note that what encodeURIComponent encodes and what Tapestry
encodes are not consistent (e.g tapestry doesn't encode a ":" whereas
encodeURIComponent does). Also Tapestry converts a "$" to "$$", and
Tapestry's hex is lower-case, whereas encodeURIComponent is upper-cased.
There may be other differences too.
So I have instead ported the tapestry service method
URLEncoderImpl.encode(String input) to javascript. I haven't tested on a
huge number of urls, but it seems to work. I have though tested the hex
encoding against the main pertinent characters (!, &, ?, %,
~, ; /, ....) and they seem to all tally. For posterity this is the
javascript:
_SU3.tapestryEncodeUri = function(uri) {
var ENCODED_NULL = "$N";
var ENCODED_BLANK = "$B";
if (uri == null) return ENCODED_NULL;
if (uri == "") return ENCODED_BLANK;
var dirty = false;
var encodedUri = "";
var safe = new RegExp(/[a-zA-Z0-9\-_\.:]/);
for (var i = 0; i < uri.length; i++) {
var ch = uri.charAt(i);
if (ch == '$') {
encodedUri = encodedUri + "$$";
dirty = true;
continue;
}
if (ch.match(safe)) {
encodedUri = encodedUri + ch;
continue;
}
var encodedCh = _SU3.tapestryEncodeChar(ch);
encodedUri = encodedUri + encodedCh;
dirty = true;
}
return dirty ? encodedUri : uri;
};
_SU3.tapestryEncodeChar = function(char) {
var chAsInt = char.charCodeAt(0);
var hex = chAsInt.toString(16);
var encodedCh;
if (hex.length == 2) {
encodedCh = "$00" + hex;
} else if (hex.length == 3) {
encodedCh = "$0" + hex;
} else if (hex.length == 1) {
encodedCh = "$000" + hex;
} else {
encodedCh = "$" + hex;
}
return encodedCh;
};
Cheers, Richard.
