Passing Javascript Variable in embedded C#

Question

I have a function in C# which can be called like this:

string result = CachedLanguageItems.GetLabel("RandomLabel").Value

It returns me the cached value of the RandomLabel .
Now I want to use this method in Javascript like this:

var result = <%= CachedLanguageItems.GetLabel("RandomLabel").Value %>

This is also working. It returns me the cached value of RandomLabel .

The problem that I am facing now is, that I am not able to pass a javascript variable to the method instead of a hard coded string. eg:

var javascriptVariable= "RandomLabel"
var result = <%= CachedLanguageItems.GetLabel(javascriptVariable).Value %>

Can somebody tell me how to pass the javascript variable correctly to the embedded c# call of the method?

Do I have to escape the embedded code for this?
Is this even possible?

Thanks for the help.

This is not possible. The C# code is evaluated on the server before the HTML is shipped to the browser. The JS code runs on the client (the browser). What you could do it write a small service which you call via AJAX that returns the value you need.
