I have created this JSFIDDLE and changed the boolean parse because that was blowing up. Thanks, Pierre! This has saved me a lot of time.

javascript:

function confirmation(question) {
var defer = $.Deferred();
$('
')
    .html(question)
    .dialog({
        autoOpen: true,
        modal: true,
        title: 'Confirmation',
        buttons: {
            "Yes": function () {
                defer.resolve("true");//this text 'true' can be anything. But for this usage, it should be true or false.
                $(this).dialog("close");
            },
            "No": function () {
                defer.resolve("false");//this text 'false' can be anything. But for this usage, it should be true or false.
                $(this).dialog("close");
            }
        },
        close: function () {
            //$(this).remove();
            $(this).dialog('destroy').remove()
        }
    });
return defer.promise();
};

function onclick(){
var question = "Do you want to start a war?";
confirmation(question).then(function (answer) {
    console.log(answer);
    var ansbool = (String(answer) == "true");
    if(ansbool){
        alert("this is obviously " + ansbool);//TRUE
    } else {
        alert("and then there is " + ansbool);//FALSE
    }
});
}

$("#item").on('click', onclick);

HTML:

Hello, click me.
