O.P. Greasemonkey message box / redirect
Is there a way to look for a word on a page using Greasemonkey, and if that word appears anywhere on the page, either display a message box, that the user has to click OK, or just redirect to another page instantly?

RE: Greasemonkey message box / redirect
how about
JS code: if (/someword/m.test(document.body.innerText)) alert("OMFG")
but that would include any other inline stuff in the source (js in <script> tags, css etc)

O.P. RE: Greasemonkey message box / redirect
Well, I've managed to come up with this, although it spams the alert for every instance of the word. How could I make it only alert once?
js code: // ==UserScript==
// @name Alert
// @namespace --
// @description Alert
// @include *
// ==/UserScript==
(function() {
const WORD = {
"test": {"color": "red"},
};
function highlightText() {
var allTextNodes = document.evaluate('//text()', document, null,
XPathResult.ORDERED_NODE_SNAPSHOT_TYPE,
null);
for (var i = 0; i < allTextNodes.snapshotLength; i++) {
var ele = allTextNodes.snapshotItem(i);
for (var key in WORD) {
if (ele.nodeValue.toLowerCase().indexOf(key) != -1) {
var span = document.createElement("span");
ele.parentNode.replaceChild(span, ele);
span.appendChild(ele);
for (var css in WORD[key]) {
span.style[css] = WORD[key][css];
alert("test");
}
}
}
}
}
highlightText();
})();
Also, what if the word wasnt actually hardcoded into the page source, but retrieved from a session, or something, how could I detect the word then?

To prevent alert spamming you could just build in a variable in place of the alert that is changed to 1 when a word is found, then after the search has been made, check the variable, if = 1, alert...
js code: // ==UserScript==
// @name Alert
// @namespace http://sammyservers.com
// @description Alert
// @include *
// ==/UserScript==
(function() {
const WORD = {
"test": {"color": "red"},
};
//build in the global variable...
var j = 0;
function highlightText() {
var allTextNodes = document.evaluate('//text()', document, null,
XPathResult.ORDERED_NODE_SNAPSHOT_TYPE,
null);
for (var i = 0; i < allTextNodes.snapshotLength; i++) {
var ele = allTextNodes.snapshotItem(i);
for (var key in WORD) {
if (ele.nodeValue.toLowerCase().indexOf(key) != -1) {
var span = document.createElement("span");
ele.parentNode.replaceChild(span, ele);
span.appendChild(ele);
for (var css in WORD[key]) {
span.style[css] = WORD[key][css];
//changes the global variable to 1
j = 1;
}
}
}
}
}
highlightText();
if(j = 1){
alert("test");
}
})();
I'm, not too strong on the javascript front so the code might not be solid, but in theory it should work!
As for searching the word outside of the source I have no clue...

Oh yeah, don't know why I didnt think of doing that. Thanks a lot.
IF anyone has any suggestions on how to search for the word outside of the page source, I would be highly grateful.

I don't actually get what you're trying to do tbh, I understand about looking for a word in a page source, but when would you find, or even look, for a word outside of that? Example of where you're trying to find the word?

O.P. RE: Greasemonkey message box / redirect
Well, this is for a friend of mine, and its for a game called Pokemon battle arena. He wants it to alert him when the word "shiny" is found in the page, but since this isnt hardcoded, and the URL has a random set of arguments for each pokemon encounter, I was wondering if there would be a way to scan the page body, even if the word wasnt in the source.

Ah, I've just taken a look at the game. I see what you mean about it not actually being in the source, but I can see where the text is meant to appear in the source, it's just been hidden. Hmm... I'm not too sure at the moment, if I think of a method I'll let you know.

Okay then, thank you very much.

RE: Greasemonkey message box / redirect
