@Renato Formato:

Very nice.  Perhaps DOM tree walking would be better than my blanket
regex over HTML...

Thanks.

you can give a look at the SearchHighlight plugin 
(http://www.jquery.info/spip.php?article50).


It is search related but using the keys option can do what you want.

My latest attempt tries to handle if the "unlink" file is missing and
uses a linkTopicsOnce setting:

(function($) {

$.fn.extend({
linktopics: function( settings ) {
var self = this;
this.settings = $.extend({}, $.linktopics.defaults, 
settings);
this.topics = null;
this.trimTopics = function () {
for ( var i = 0; i < self.topics.length; i++ ) {
var allowed = true;
for ( var j = 0, numStopLinks = 
self.stopLinks.length; j <
numStopLinks; j++ ) {
if ( self.stopLinks[j] == 
self.topics[i].topic ) {
allowed = false;
break;
}
}
if ( ! allowed ) {
void( self.topics.splice( i, 1 
) );
}
}
};
this.setupRegexes = function () {
for ( var i = 0, numTopics = 
self.topics.length; i < numTopics; i+
+ ) {
self.topics[i].linked = false;

self.topics[i].strings.sort(function(a,b) { // longer strings
come first
if ( a.length > b.length ) {
return -1;
} else if ( a.length < b.length 
) {
return 1;
} else {
return 0;

self.topics[i].regexes = new

What happens if there is other HTML -- be it other spans or links --

2007-06-02 Thread Michael Edmondson 

This hasn't been strenuously tested yet...

What little I've put together so far is here:  http://cosmicforge.com/topics/

This is my first time using jQuery, and so I'm attempting to make a
proper plugin instead of just random functions.

The functionality is very focused as written -- it purposefully only
links the first occurrence found, but I suppose that part could be
made optional -- oh, and it doesn't do any error checking, and it
doesn't work if the JSON files are missing, so there's plenty of work
still to be done.

And for those of you who just want to look at code...


jQuery(function($) {
$("div.storytext > p").add("div.storytext > ol >
li").add("div.storytext > ul > li").linktopics();
});


A single (object) param to be passed to linktopics:

{
topicLinkJsonUrl: "URL to JSON file with topic data",
topicUnlinkJsonUrl: "URL to JSON file with list of topics NOT to
link"
}


JSON for topics to be linked:

{
"topics": [
{
"topic": "jQuery",
"link": "http://jquery.com/";,
"strings": [
"jQuery",
"Javascript framework",
"John Resig"
]
},
...
}


JSON for topics NOT to be linked:

{
"stoplinks": [
"Michael Edmondson"
]
}


/**
 * jquery.linktopics.js
 */

(function($) {

$.fn.extend({
linktopics: function( settings ) {
this.settings = $.extend({}, $.linktopics.defaults, 
settings);
this.topics = null;
var self = this;
$.getJSON( self.settings.topicLinkJsonUrl, 
function(json) {
if ( typeof json.topics == "object" ) {
self.topics = json.topics;
self.stopLinks = new Array();
$.getJSON( 
self.settings.topicUnlinkJsonUrl, function(json) {
if ( typeof json.stoplinks == 
"object" ) {
self.stopLinks = 
json.stoplinks;
}
for ( var i = 0; i < 
self.topics.length; i++ ) {
var allowed = true;
for ( var j = 0, 
numStopLinks = self.stopLinks.length; j <
numStopLinks; j++ ) {
if ( 
self.stopLinks[j] == self.topics[i].topic ) {
allowed 
= false;
break;
}
}
if ( ! allowed ) {
void( 
self.topics.splice( i, 1 ) );
}
}
for ( var i = 0, numTopics = 
self.topics.length; i < numTopics; i
++ ) {
self.topics[i].linked = 
false;

self.topics[i].strings.sort(function(a,b) { // longer strings
come first
if ( a.length > 
b.length ) {
return 
-1;
} else if ( 
a.length < b.length ) {
return 
1;
} else {
return 
0;
}
});
self.topics[i].regexes 
= new
Array(self.topics[i].strings.length);
for ( var j = 0, 
numStrings = self.topics[i].strings.length; j
< numStrings; j++ ) {

self.topics[i].regexes[j] = new RegExp( "(^|\\W)(" +
