Pass variables from java to javascript

Question

I'm new to JavaScript programming, and I have a question that I could not find an answer to anywhere.

I have some code in Java that does some stuff with two double arrays

double[] arrX = new double[sizeA];
double[] arrY = new double[sizeB];

Then, I need to pass these two variables to a html/JavaScript code that need to use them.

Is that possible?

Not necessarily AJAX. They could be set as request attributes to be picked up in a JSP. But we don't know nearly enough about the OPs application to offer much help. — GriffeyDog

False. Its also possibly done as a Java Server Page (JSP) Edit: GriffeyDog was faster :) — David Fariña

Yes, it's possible. It can be done in multiple ways and it depends on the architecture of your app and the frameworks that you are using. — Vivin Paliath

Would recommend following:

You would find values in variables shown in GUI.

Next Step assigning java variables to javascript variables, use following syntax

<script type="text/javascript">
var jsVariable =<%javaVariable%>;
</script>

Hoping this helps.

Cheers !!

You better not give an example of scriplets to a newcomer.. :) Just give a hand in researching of Servlet API and JSP would be good.

@ConstantineNovykov - You are right, just though to tell hiim its possible.
