How to Call Javascript Function from Freemarker?
I Have Some Basic Javascript Function: Function someTestFunction(param1, Param2) { //Do Something } and Freemarker Code: // Call: someTestFunction(something...
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.
