ETFbitcoin, what did you exactly put in the first field of the tx, labeled
 Address, WIF key, Redeem Script or Transaction ID:, an address, a script, a TxID or a key?  I enter my address and itīs not accepted, and my goal is to use my address, if possible.

You can do that by open "Help" -> "Setting" or visit https://coinb.in/#settings and choose "Bitcoin (Testnet)" on Network option.

Not working at all, now trying another one: mm7BAhJKvL9FrAim1gCYoM3WJHGYYfcXLV

The address or redeem script you have entered is invalid

Is testnet working to you on coinb.in?

Thank you, guys, all answers add priceless info to my knowlege. Now, some details:

Iīm cuban, so my connection is not the best to npm libraries; it takes too long. Is there a way to npm my already dowloaded lib instead?

Now some other considerations: if bitcoinjs-min.js can be used in an off-node manner, why not the same principle to build a Tx with same lib? Any special reason?

No matter whether bitcoinjs-lib.js or -min.js, as stated by me before, no matter if more -libs are needed, the matter is to manage a .js lib like any other .js file, just from the browser. If not possible, a reason could be indicated.

Iīm aware that more steps are needed, of course, but the function to create a new public address/private key is in the same lib containing functions to build a transaction. No matter how many steps, npm installation doesnīt add functions to the library, and this is a .js file, not a special one that can only be read by node.js, I guess.

Hope you understand my concern.

ETFbitcoin, coinb.in is according to my goal: prepare an off-line Tx. However, a testnet addr is not accepted:
"The address or redeem script you have entered is invalid". Thatīs the message. My addr is fine and funded:

muKdpCX1tGhaREkY9foqSkPCCQqXbXB6QQ, but is not accepted, even after selecting bitcoin testnet at setting page. Any sugestion? I wanna test the wallet with fake btc before entering real money addr/key in mainnet.

Thank you all.

Hello. This link leads to a solution posted by someguy123 with bitcoin-min.js to generate public addr/private key, just with 3 lines of code:
https://bitcointalk.org/index.php?topic=750022.msg9974990#msg9974990

The method is:

First, for the head in html document:

Code:
<script src="js/bitcoinjs-min.js"></script>

Then the function to call is:

Code:
var key = Bitcoin.ECKey.makeRandom();
var PubKey = key.pub.getAddress().toString();
var PrivKey = key.toWIF();

And that's it. An elegant, "nodeless" solution.

My issue is this: How to use such a simple method, but for building a btc transaction instead? You know, a nodeless method, just a dir with bitcoinjs-lib inside (or -min, whatever) and pure javascript to call the corresponding functions.

Thank you in advance.
