How to call custom action by jquery

suppose the below code is my web api code

public class ProductsController : ApiController
{
    public IEnumerable<Product> GetAll() {}
    public Product GetById(int id, double version = 1.0) {}
    [HttpGet]
    public void FindProductsByName(string name) {}
    public void Post(Product value) {}
    public void Put(int id, Product value) {}
}

now how could i specify action method name when i like to call action by jquery.

how jquery url would look like for GetAll(), GetById(int id, double version = 1.0), FindProductsByName(), Post,Put etc.

please guide me what step i need to do and how jquery ajax code would look like to call action method with custom name.

thanks
