How to call JavaScript function from Freemarker?
Mia Lopez
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.
