get global variable , from function `change`

function getSelectData(id) {
var value='';

    // set value to be the current selected value
value = jQuery(id+" option:selected").val();

// change value whenever the box changes
jQuery(id).change(function () {
    value = jQuery(id+" option:selected").val();
});

console.log(value);
return value;

}

You can't unless you move it to be a global variable. As it is, the line "console.log(value)" will only print the value before the function change() is called. (change() gets called when something changes....but that is long after getSelectData() has returned).

Here, use this as a template to solve your problem:
