Question

Is there anyway that I can save or access a local variable outside of it’s function? Consider the code below:

$( "#droppable2" ).droppable({
        activeClass: "ui-state-hover",
        hoverClass: "ui-state-active",
        accept: "#draggable3",
        drop: function( event, ui ) {

            jdc = $(this).attr("id"); //I need to use this value later
            $( this )
                .addClass( "ui-state-highlight" );
                var x = ui.helper.clone();   
                x.appendTo('body');

                var jdi = $("img").attr("id");// I need to use this value later

                $(this).droppable( 'disable' );
        }
    });

Is there anyway to get the values of the two variables (jdc and jdi above) for later use outside of the function?

The ultimate goal is to get id of droppable container and content of dropped element.

Answer 1

try this:

jQuery(element).data(key,value);
// Store arbitrary data associated with the matched elements.

or declare your variable outside the function.

var example;

function abc(){
   example = "12345";
}

abc();

console.log(example);
