Is there a way to assign or initialize a Java array as a JavaScript array without relying on JSP?

I'm currently developing in the Play framework and I'm facing a challenge with using a Java array inside Javascript.

My attempt so far is as follows -

var jsarray = ${javaArray};

The javaArray refers to the array stored in the Java controller and passed to the HTML view.

Unfortunately, this approach doesn't seem to be working. Can someone offer assistance on how to properly handle this?

Answer №1

Keep in mind that you are not passing variables... You are actually writing JavaScript code

Therefore, ensure that your array is formatted properly for JavaScript

var jsArray = [%{javaArray.eachWithIndex{it,idx->
                 }%
                 ${it}${(idx<javaArray.size()-1)?",":""}
                 %{
                 }
                 }%]

Choose a method that works well with your template engine. You will need to loop through your array and display the values on the view

Note: I have used Groovy notation in this example...
