How to get dropdown changed value from in jquery to another function

Question

This is my code

$(function(){
    $('#dropdown_name').change(function(){
        var V = $('#dropdown_name').val();
        var T = $('#dropdown_name :selected').text();
    });
});

I want to send V and T's value below function

function xyz()
{
    a = V;
    b = T;
    alert(a);
    alert(b);
} 

In Function xyz, I have to call many function so I don't want, it take as parameter of xyz function. So how can I get data in another way when I will select a dropdown then it will display alert(a and b) that value and text of dropdown.

How to solve it, please any suggestion.

You can use global variables instead:

function xyz()
{
    a = window.V;
    b = window.T;
    alert(a);
    alert(b);
} 

You will call the function like so:

$(function(){
    $('#dropdown_name').change(function(){
    window.V = $('#dropdown_name').val();
    window.T = $('#dropdown_name :selected').text();
    });
});
