How to call JavaScript function from Freemarker?

rated 0 times [ 196] [ 2] / answers: 1 / hits: 24750 / 12 Years ago, wed, july 4, 2012, 12:00:00

I have some basic JavaScript function:

<script type=text/javascript>

    function someTestFunction(param1, param2) {

        //do something

    }

</script>

and Freemarker code:

<#if something==somethingElse>

    // call: someTestFunction(something, 123)

<#else>

    // call: someTestFunction(somethingElse, 345)

</#if>

my question is: Is it possible, and if so, how to call someTestFunction() from inside freemarker tags?

Freemarker is a java templating language, meaning it is executed on the server. javascript is executed on the client (user's browser). You cannot call a javascript function from the java server in this manner.

You could do something like:

<script>

<#if something==somethingElse>

    someTestFunction(something, 123);

<#else>

     someTestFunction(somethingElse, 345);

</#if>

</script>

which means the javascript wll be executed on the client side depending on what server variable is set.
