Implementing separate JavaScript files for individual view pages in Play Framework: A step-by-step guide

Is there a way to define different javascript files for various view pages in the play framework?

One approach is:

@main(title, """
@*JS CODE*@"""
{
//Template Codes
}

Then in the main template, it can be used like this:

@(title,stringJS){
<script>
@Html(stringJS)
</script>
}

However, what if the JS code needs to be used on only specific pages and not all? It wouldn't make sense to copy the JS code into every related view page. In my situation, all javascripts are loaded in the footer, which is a separate template.

How can we address this issue??

Any assistance would be greatly appreciated. Thank you!

Answer №1

The various scenarios in which templates can be used are detailed in the documentation under the title Common templates use cases, specifically in the section on 'moreScripts and moreStyles equivalents'.

To summarize, the functionality is as follows:

@moreScripts = {
    <script type="text/javascript">alert("hello !");</script>
}

@moreStyles = {
    <style>background: pink;</style>
}


@main("Title", moreScripts, moreStyles){

   Html content here ...

}

In the file main.scala.html, it begins as shown below:

@(title: String, moreScripts: Html = Html(""), moreStyles: Html = Html(""))(content: Html)

<!DOCTYPE html>

<html>
    <head>
        <title>@title</title>
        <link rel="stylesheet" media="screen" href="@routes.Assets.at("stylesheets/main.css")">
        @moreStyles
        <script src="@routes.Assets.at("javascripts/jquery-1.7.1.min.js")" type="text/javascript"></script>
        @moreScripts
    </head>
    <body>
        @content
    </body>
</html>

Answer №2

Huge thanks to this Helpful post on Stack Overflow for guiding me to my solution. Here's how I tackled it:

@main(title, """
@*Instead of JS code, just the declaration itself*@
<script src="/assets/javascripts/libs/main.js" type="text/javascript"></script>
<script src="@routes.Assets.at("javascripts/libs/main.js")" type="text/javascript"></script>//Encountered errors with this approach, so resorted to hardcoding the "src" location
"""{
//Template Codes
}

If there are more efficient ways to address this problem, I am open to suggestions. Hard-coding the src doesn't seem like the optimal solution in my opinion.
