Orchard and editing page - adding script - orchardcms

Question

I can add a script to a page via the dashboard (by editing the page Content Item as html). The script is added to the page and evaluated, but too early - none of scripts are loaded yet (for example, jQuery).
I don't want to add the script to Layout, as it makes no sense to add this script for all pages.
Is there any way to add a script to a single page's content via the dashboard, so that it can be evaluated properly?
Or should I create a separate module that contains a special content part (to include proper scripts for the view/shape) and add that part to a custom ContentType (that also contains BodyPart and others such as Page Content Items)?
Or should I separate the whole content in such a way that interactive parts are widgets and should not be edited in Page Content Item?

Answer 1

Can you use the Script.Foot() extension method ?
#using(Script.Foot()) {
...
}
Using jQuery from Orchard module page

Answer 2

You can add the script file to the top of the html content like below:
<p>
<script type="text/javascript" src="/*path of the file*/">// <![CDATA[
// ]]></script>
</p>
Steps to add: Dashboard->Content->open the particular page->Html source editor->In the top add the above script with your script file path.

Answer 3

I suggest adding a part for your script, something like:
public class CustomScriptPart : ContentPart<CustomScriptPartRecord>
{
public bool AtFoot
{
get { return Record.AtFoot; }
set { Record.AtFoot = value; }
}
public string Script
{
get { return Record.Script; }
set { Record.Script = value; }
}
}
Views/Parts/CustomScript.cshtml
#if(Model.AtFoot) {
using(Script.Foot()) {
<script type="text/javascript">
#Model.Script
</script>
}
} else {
<script type="text/javascript">
#Model.Script
</script>
}
But probably something similar is already done, by Vandelay Industries for example.
