Tips for accessing a variable value within a JavaScript function

I am currently facing an issue where I am unable to retrieve a variable from a JavaScript function and use it outside of the function. While I can successfully output the variable value inside the function, I am struggling to access it elsewhere in my script. Here is the code snippet, but I need help figuring out how to extract the value of 'status' and utilize it outside of the function:

       <script>
            function get_id(){              
                $('.addressClick').click(function() {
                    var status = $(this).attr('id');
                    alert(status); // The correct value is displayed here
                    return status;
                });
            }

            var variable = get_id();
            alert(variable);        // The variable isn't displaying here

            $("#"+variable).confirm();
    </script>

Answer №1

Attempting this action is not advisable, and here is an illustration:

function get_id(){              
    $('.addressClick').click(function() {
        //...
    });
    return 12;
}

var variable = get_id();
alert(variable); //12

The line 'return status;' is within the event function, not the get_id function.

A better approach would be (avoid using global variables in extensive projects) :

$('.addressClick').click(function() {
    $('.statusSelected').removeClass('statusSelected');
    $(this).addClass('statusSelected');
});
alert($('.statusSelected').attr('id'));

$("#"+variable).confirm();
