Using code blocks in Javascript


when I access an ASP control I've just to include it's client ID:
<script type="text/javascript">
<%= Speichern.ClientID %>

But how can I do this in an external js file?
When I try <script type="text/javascript" src="myjs.js">
<%= Speichern.ClientID %> eber returns null.

Is there a way to use it?

Store it in global variable which you will use in the external file.

var client_id = <% ... %>;

<script src="external/file.js" />

Is this really the only way to do so?
I don't say it's only way, you can generate the external file along the web page, but I don't think that's better solution.
