is there a script that highlights specific words that I want on any site/page?

please.

please.

var b = document.body;
b.innerHTML = b.innerHTML.replace(new RegExp("("+"your word"+")"), "<span style='color:#f00;font-weight:bold;'>$1</span>");

Crappy way, dob.

var RE = /(script)/;

for (var tx = document.evaluate('//text()[normalize-space(.)!=""]', document, null, 6, null), t, i = 0; t = tx.snapshotItem(i); i++) {
	var before =  t.textContent, st, matched = false;
	if (t.parentNode.tagName == 'STYLE' || t.parentNode.tagName == 'SCRIPT') continue;
	while ((st = before.search(RE)) != -1) {
		t.parentNode.insertBefore(document.createTextNode(before.substr(0, st)), t);
		t.parentNode.insertBefore(document.createElement('b'), t).textContent = RegExp.$1;
		matched = true;
		before = before.substr(st + RegExp.$1.length);
	}
	if (matched) t.textContent = before;
}

That's why I'm still learning :)

thanks mikado, worked...but is there a way I can add more words? and also color them instead just bold?

also when I add a word like (My Home) it only highlights exactly as it's typed, like it doesn't highlight (my home) just (My Home)
with capital letters.

thanks.

please.

var RE = /(phrase one|phrase two|etc)/i; - i at the end stands for case insensivity.

Replace t.parentNode.insertBefore(document.createElement('b'), t).textContent = RegExp.$1; with:

with (t.parentNode.insertBefore(document.createElement('span'), t))
	textContent = RegExp.$1,
	style.cssText = 'color: #f00; size: 14pt;';

Add any styles you like to the cssText string.

multi word/case insensivity worked.
without replacing the color code.

but when I replace, the script doesnt work at all.

please.

I've mismatched quotes in that line, try again.

k.

nope, still not working.

Working for me.

not working for me.
can't you just repost the full (working) script?

var RE = /(e)/;

for (var tx = document.evaluate('//text()[normalize-space(.)!=""]', document, null, 6, null), t, i = 0; t = tx.snapshotItem(i); i++) {
	var before =  t.textContent, st, matched = false;
	if (t.parentNode.tagName == 'STYLE' || t.parentNode.tagName == 'SCRIPT') continue;
	while ((st = before.search(RE)) != -1) {
		t.parentNode.insertBefore(document.createTextNode(before.substr(0, st)), t);
		with (t.parentNode.insertBefore(document.createElement('span'), t))
			textContent = RegExp.$1,
			style.cssText = 'color: #f00; font-size: 14pt;';
		matched = true;
		before = before.substr(st + RegExp.$1.length);
	}
	if (matched) t.textContent = before;
}

is there another way to do the var? i added the words i want to highlight and its a pretty large list and it causes the script to stall

How could I use this script to replace text smilies with images (data: uris)?

I cant figure it out

This is what I need to incorporate it in:

var happy = "data:image/gif;base64,R0lGODlhEQARALMAABy+ASTTAiXWAiHLAhWtARawAR7EARq ... ";

function replaceSmilie(smilie, surl)
{
  var reptext = new RegExp(smilie, "gi");
  document.body.innerHTML = document.body.innerHTML.replace(reptext, "<img src='" + surl + "' height='17' width='17' align='center' style='border:none;' />");
}

replaceSmilie(":\\)", happy);

Someone told me that using innerHTML replace was much slower, but I dont know how to use your way.

Note: this script deletes words inside textareas instead of highlighting them. (Tested with Firefox 3 and Safari 3.)
Workaround: exclude pages with textareas in greasemonkey or greasekit.
