Variable in JavaScript callback functions always gets last value in loop? [duplicate]

Answer 1

I also found this solution at http://meshfields.de/event-listeners-for-loop/:

var myArr = [0,1,2,3]; 

for (var i = 0; i < myArr.length; i+=1) { 

(function (i) { 

    document.getElementById('myDOMelement' myArr[i]).onclick = function () { 

        if (window.console.firebug !== undefined) { 
            console.log('myDOMelement' myArr[i]); 
        } 
        else { 
                alert('myDOMelement' myArr[i]); 
        } 
        }; 
    }) (i); 
}
