Load a script and process it inmediately

Jesús Ángel

Hello.

I have a script (S1) that depends on other script (S0) so I have to
include both scripts in all pages:

<script type="text/javascript" src="/js/S0.js"></scrip>
<script type="text/javascript" src="/js/S1.js"></scrip>

I have read that is is posible to load one script from any other:

function loadScript (scriptUrl) {
var head = document.getElementById("head");
var script = document.createElement("script");
script.type = "text/javascript";
script.src = url;
head.appendChild(script);
}

Supose that I want to load S1 from S0:
S0.js:
../..
loadScript('S1.js');
s1Function(); // A function defined inside S0

index.shtml:
<head>
<script src="S0.js">
</head>

The code above doesn't work because S1.js it is loaded after the end of
S0.js and not when I load S1.js with loadScript.

¿It is posible to load S1.js right after invoke loadScript('S1.js') so I
could use S1 functions' in S0.js?

Thanks.

There is a "t" missing in both end tags, but maybe that's only a typo
duplicated by copy and paste.
I have read that is is posible to load one script from any other:

function loadScript (scriptUrl) {
if (document.getElementsByTagName)
{
var head = document.getElementById("head");
Instead:

var head = document.getElementsByTagName("head");
if (head && (head = head[0]) && document.createElement)
{
var script = document.createElement("script");
if (script && head.appendChild)
{
script.type = "text/javascript";
script.src = url;
head.appendChild(script);
}
}
} }

../..
loadScript('S1.js');
s1Function(); // A function defined inside S0

index.shtml:
<head>
<script src="S0.js">
</head>

The code above doesn't work because
there are the following items missing:

- the "id" attribute value "head" for the "head" element, if you
want to use getElementById() instead of getElementsByTagName()
- the "title" element
- the "type" attribute value for the "script" element
- the </script> tag.
S1.js it is loaded after the end of
S0.js and not when I load S1.js with loadScript.
No, see above.

No, because that would mean that both script files would depend on each
another (cross dependency). loadScript() only works within HTML files
and on few browsers, i.e. only if there is a document which provides
the object model that is required by the method.
