This is an old question, covered in hundreds of FAQs, but a reader asked me this today and I'm nothing if not responsive. (Especially when I know the answer. ;) The question was - how do you open a new window in JavaScript with as little chrome as possible. JavaScript makes this rather simple. The syntax to open a new window is:

foo =, varname, features);

Where features is a list of ... well, features. This includes chrome, size, and other options. I found a good list here.

So to answer the question - you can simply disable all the features that are chrome related like so:

<script> function popup() { var features = 'directories=no,menubar=no,status=no,titlebar=no,toolbar=no,width=500,height=500'; var mypopup ='', 'mypopup', features); } </script>

<form> <input type="button" onclick="popup()" value="Click me, baby"> </form>

In my features list I disabled directories, menubar, status, titlebar, and toolbar. Note though that status=no will not work in Firefox or IE7, due to security settings, which is probably a good thing.
