jquery callback function only working on last loop

Question

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


    actualBarHeight = Math.floor((barValues[i] / chartMaxY) * barchartHeight);

    var barChartID = \"#barChart\"          


        

Answer 1

Since you are using jQuery you can use the $.each function instead of a for loop. The callback used instead of the loop will create a new closure.

$.each(barValues, function(i, barValue){
    actualBarHeight = Math.floor((barValue/chartMaxY)*barchartHeight);

    var barChartID = "#barChart" + (i+1)
    $(barChartID + " .value span").css('background-color','transparent');
    $(barChartID + " img").animate({ 
                    height: actualBarHeight
            }, 500, function(){$(barChartID + " .value span").css('background-color','white');}
    );

    $(barChartID + " .value span").html("$"+Math.floor(barValue));
    $(barChartID + " .value").css("bottom",actualBarHeight+"px");
    $(barChartID + " .ylabel").html(chartMaxY);
});
