I have no clue and this would be my 1st time even touching JS so can someone spoon feed me but still teach me how to quote lines of text with JS? like I want the user to click a button and have something pop up that they can copy and it would have the quoted post content on it.

depends on how you envisage what you are going to do.

would it be something like the posting system on forums such as here?
Or something like I have for code snippets? http://www.modtalk.co.uk/article/c-a...gn/dhtml-tabs/
(click on the text "Click to switch code view" in the code box header)

Or something else?

Well I want something like you click a button near someones post and it pop-ups a new window with the post on it and with the "[quote]" at the beginning and end.

Actually that would be better done with server side script, and the button passes the post id to be quoted, then the page generating script reads the post data from the database and inserts it into the <textarea> of the editor.

exactly like the "Quote" works here. ( /newreply.php?do=newreply&p=812245 )

Well I would just rather go with the button that prompts the post and the post ID would be easily implemented, or should be.

function addQuote(p_iID) {
    var l_sTag = "quote";
    var l_sQuoted = document.getElementById(p_iID).innerHTML;
    document.formname.textareaname.value = "[" + l_sTag +"]" + l_sQuoted + "[/" + l_sTag +"]";
}

code to go on the button to get the text to be quoted;

onclick="addQuote(ID_of_post_container)"

That will replace ANY text already in the textarea with the quoted text, Inserting the text at the cursor point is somewhat more complicated.

There is no text area on the thread, just posts and a button to reply. So I need them to copy the text in the popup.

for JS is classpatch needed?

I bet you thought this is a very simple thing with an "alert" or "prompt" dialog

See it working at -> http://www.modtalk.co.uk/_site/code/...pt/post-quote/

<div id="post_123456" class="post"><div class="post_header"><span id="quote_123456" class="btn_up" onclick="addQuote(this.id)" onmousedown="this.className='btn_down'" onmouseup="this.className='btn_up'">Quote</span></div>
<div id="text_123456">This is some text that will be quoted into the next post.
<br>
<br>
This is a second line.

some more text following line breaks</div>
</div>

<script type="text/javascript">
var m_bSet = false;

function addQuote(p_iID) {
if (!m_bSet) {
var l_sTxtID = p_iID.replace("quote","text");
var l_sPostID = p_iID.replace("quote","post");
var l_oPost = document.getElementById(l_sPostID).id;
var l_oLB = document.createElement("br");

    var l_sTag = "quote";
    var l_sQuoted = document.getElementById(l_sTxtID).innerHTML;
		l_sQuoted = "[" + l_sTag +"]" + l_sQuoted + "[/" + l_sTag +"]";

	var l_oHolder = document.createElement("div");
		l_oHolder.setAttribute("id","holder");
	document.getElementById(l_oPost).appendChild(l_oHolder);

	var l_oNewTextArea = document.createElement("textarea");
		l_oNewTextArea.setAttribute("cols","60");
		l_oNewTextArea.setAttribute("rows","5");
		l_oNewTextArea.setAttribute("name","postquote");
		l_oNewTextArea.setAttribute("id","postquote");
	var l_oNewFieldLabel = document.createElement("label");
		l_oNewFieldLabel.setAttribute("for",l_oNewTextArea.id);
		l_oNewFieldLabel.innerHTML = "Copy the text below ";
	var l_oCloseQuote = document.createElement("span");
		l_oCloseQuote.setAttribute("class","btn_close");
		l_oCloseQuote.setAttribute("id",p_iID.replace("quote","close"));
		l_oCloseQuote.innerHTML = "Close";
		l_oNewFieldLabel.appendChild(l_oCloseQuote)
			
	document.getElementById("holder").appendChild(l_oNewFieldLabel);
	document.getElementById("holder").appendChild(l_oLB);
	document.getElementById("holder").appendChild(l_oNewTextArea);
		l_oNewTextArea.value = l_sQuoted;
		l_oNewTextArea.setAttribute("onclick","this.select()");
	document.getElementById("postquote").onclick = function() {this.select();};
		l_oCloseQuote.setAttribute("onclick","removeQuote(this.id)");
	document.getElementById(p_iID.replace("quote","close")).onclick = function() {removeQuote(this.id);};
	m_bSet = true;
}
}

function removeQuote(p_iID) {
var l_sQuoteID = p_iID.replace("close","post");
var l_oQuote = document.getElementById(l_sQuoteID);
var l_oHolder = document.getElementById("holder");
	l_oQuote.removeChild(l_oHolder);
	m_bSet = false;
}
</script>

This code can only handle a single post being quoted at any one time (only one set variable)

I'll leave you to put it into a "popup" if you wish

Thanks, some small editing and I should have it 100% of what I need.
