Talk To The Hand: userscript for hiding tagged entries

[vinnie_tesla]

Talk To The Hand is a Greasemonkey userscript that allows Firefox users to hide entries with selected tags from your Livejournal friends page view. This edition is only known to work with the A Sturdy Gesture page layout. Ports to some other layouts should be trivial (I plan to do a Generator one this afternoon), but I haven't manged to figure out

Very cool! I couldn't get it to work for Smooth Sailing, so that's one reason I'm changing my layout to Flexible Squares, because I was able to edit it:

// ==UserScript==
// @name TalkToTheHand
// @namespace http://vinnietesla.com/amusements/
// @description hides Livejournal entries with selected tags
// @include http://*.livejournal.com/*friends*
// ==/UserScript==

// This edition only works with the Flexible Squares layout. You need
// to modify the @include field above, replacing my username with yours.

var kills = 0;
var blist = new Array();
var btags = new Array();

tagDivs = document.evaluate(
"//a[@rel='tag']",
document,
null,
XPathResult.UNORDERED_NODE_SNAPSHOT_TYPE,
null);
for (var i = 0; i < tagDivs.snapshotLength; i++) {
var redx = document.createElement('span');
redx.style.color = "#fcf";
redx.style.fontWeight = "bold";
redx.style.cursor = "pointer";
var theex = document.createTextNode("x");
redx.appendChild(theex);
var thistag = tagDivs.snapshotItem(i);
redx.setAttribute("tag", thistag.href)
redx.setAttribute("tagname", thistag.text)
var parent = thistag.parentNode;
parent.insertBefore(redx , thistag.nextSibling);
redx.addEventListener("click", killTag, false);
redx.addEventListener("mouseover", changeColor, true);
redx.addEventListener("mouseout", changeAgain, true);
var baleeted = GM_getValue(thistag.href);

if (baleeted > 0) {
blist[kills] = thistag.href;
btags[kills] = thistag.text;
kills++;
var walker = thistag.parentNode;
while (walker.className != 'entry_text') {
walker = walker.parentNode
}
walker.parentNode.removeChild(walker);
}
}

if (kills > 0) {
var main = document.getElementById("maincontent");

var report = document.createElement("div");
report.setAttribute("class", "box");
report.style.cursor = "pointer";
report.style.fontWeight = "bold";
report.style.color = "blue";
report.addEventListener("click", popup, true);
report.addEventListener("mouseover", changeColor, true);
report.addEventListener("mouseout", changeBack, true);
if (kills == 1){
var killcount = document.createTextNode( "One entry deleted.")
} else {
var killcount = document.createTextNode( kills + " entries deleted.")
}
report.appendChild(killcount);
main.insertBefore(report, main.firstChild);
}

Argh, comment's too long; second half to follow.
