<script type="text/javascript" src="file2.js"></script>

The attribute 'language' is of no utility (in any browser).

i want that file1.js included file2.js

By wich way ?
(what will tell to file1 to load file2)

i want the scope function of file1 ,"know" the scope of file2.js

with out contain this '<Script type="text/javascript"
Language="JavaScript" Src="file1.js "></script>'

in my index.html

<script type="text/javascript" src="file1.js"></script>

file1.js :
==========
var msg = 'hello';
document.write('<script type="text/javascript" src="file2.js">'+
'<\/script>');
//end script

or :

file1.js :
==========
var msg = 'hello';
function domLoadJS(file) {
var s = document.createElement('SCRIPT');
s.type = 'text/javascript';
s.src = file;
document.getElementsByTagName('HEAD')[0].appendChild(s);
}
// action (that can be made from html (ie: onclick in a button))
domLoadJS('file2.js');
//end script


But I don't see where is the interest to have that insteed of the normal
way that we are sure it works while calling a new script using JS could
fail with one or another browser.
I think that discusion came a lot of time here, try to see in archives
and in the FAQ <http://jibbering.com/faq/>.

I have two js files

file1.js contain
var msg="Hello world";

Should be

window.alert(msg);

Even a feature test prior to call is in order.

Scope doesn't enter into it. All such includes share the same global scope.

with out contain this '<Script type="text/javascript"
Language="JavaScript" Src="file1.js "></script>'

Lose the `Language' attribute; the `language' attribute has been deprecated
long since (HTML 4.0, 1997-12-18 CE) in favor of `type', and was never
really necessary.

Lowercase all element type identifiers and attribute names; that makes DOM
scripting a lot easier, and is required for Valid XHTML, should you want to
declare and use it (later).

in my index.html

Possible, but unreliable. Google `loadScript', or RTSL of YUI, Google Maps
v3 aso. And read the FAQ: <http://jibbering.com/faq/#posting> pp.

The attribute 'language' is of no utility (in any browser).

Not accurate. In particular 'language' attribute can be specify
"Javascript1.2" in many browsers. (Version 1.2 has some major and non-
trivial differences.)

Back to the other discussion ...

it is better to say that the Language attribute is not needed in modern
scripting.


Dynamic loading of script elements, either by document.write or creating
new script elements is fragile and their run-time execution cannot be
assured. IMHO, you are better to avoid them.
