Calling Javascript function with variables as parameters

Question

How can I call a javascript function and pass some variables to be used as parameters for instance

Say the function javascriptFunction uses 2 parameter. I will usually call it as javascriptFunction("param1", "param2") (with single quotes around the strings). But now I want to pass it some variables.

string y = "this is a string"
string x = "another"
javascriptFunction(y, x)

I have tried javascriptFunction(@y, @x), javascriptFunction("@y", "@x") (with single and then double quotes around the strings) but this does not work

EDIT I am actually making the call through a view (cshtml file). So my variables are strings.

It's always good to start learning new language with [some tutorials](https://developer.mozilla.org/en-US/docs/JavaScript/Reference). — VisioN, Jan 08 '13 at 19:33
The issue is that I do not create or initialize my variables in the javascript file but an cshtml page that uses strings — jpo, Jan 08 '13 at 19:36
Part of me wants to close this question for being so basic, but I know this is exactly the type of question that SO is made to answer. There must be a duplicate somewhere, but I can't find it. — Shmiddty, Jan 08 '13 at 19:36

JavaScript has a weak type system. There's no need to specify the types. All variables' types are determined by their values. They are created with the keyword var:

var y = "this is a string";
var x = "another";

_{[And don't forget to use semicolons!]}

Semicolons are not necessary though. – VisioN Jan 08 '13 at 19:32
Not to mention that you could use a comma after the first string (in place of a semi-colon) and omit the second `var`. – David Thomas Jan 08 '13 at 19:32
@VisioN why did you make it so small now?? – David G Jan 08 '13 at 19:36

This should work

var y = "this is a string", x = "another";
javascriptFunction(y, x);
