Use JavaScript value from jquery to javaScript function

Question

I want to get a value stored in a variable Get_Current_id in a jquery clicked function and use in a javascript PrintContent(). Any help would be appreciated.

jQuery:

$('#AgeGroupWiseButton').click(function()
{
    var Get_Current_id = $('#AgeGroupWiseButton').val();
});

js:

<script>
function PrintContent()
{

    alert(Get_Current_id );

}
</script>

Remove the var. Otherwise, it's scoped to the current function and inaccessible outside of it.

Ideally, you should have these two functions in a closure of their own, but global variables will work too.

Declare Get_Current_id outside of the jquery event handler makes it accessible to other functions. Note that Niet the Dark Absol's suggestion to just remove the var from inside the jquery event handler is bad practice as it creates an implied global (which can create confusing problems).

var Get_Current_id;

$('#AgeGroupWiseButton').click(function()
{
    Get_Current_id = $(this).val(); // no need to re-select
});

function PrintContent()
{
    alert(Get_Current_id );
}
