jquery setTimeout inside each

i have some code similar to this, that moves inside some images... it works but it doesn't seem to respect timer

var i = 1;
var indexArray = array(1,2,3);
var timerx = new Array();

$( indexArray ).each(function( indexArraykey ) {

    function internalCallback ( i, indexArraykey ) {
        val = indexArray[indexArraykey];
        console.log("test " + i + val);
    }); 

    timerx[i] = setTimeout( internalCallback( i, indexArraykey ), i * 500000 );                     

    i++;

}); 

A few points :

• i has the value of end of loop by the time the callback is called.
• to iterate over an array using jQuery, use $.each(array,, not $(array).each(
• the function doesn't have to be defined in the loop
• each gives the index as second argument of the callback and as first argument the value.

So it seems that what you want is in fact this :

var indexArray = array(1,2,3);
var timerx = [];
$.each(indexArray, function( indexArrayValue, i ) {
    timerx.push(setTimeout(function(){
        console.log("test " + i + ' : ' + indexArrayValue);
    }, (i+1) * 500000));
});
