验证图像的正确顺序

Question

我有6张图片和6个滴点。可拖动的图像被洗牌，我需要拖动它们并将它们按正确的顺序排列。如果订单不正确，则定位错误的图像应恢复，并保持正确定位。但不幸的是我遇到了一个问题，有些时候正在工作......有些时候没有:(这里有一些代码和小提琴：

编辑：http://jsfiddle.net/8H2yW/

$(dragObjects).css("cursor", "pointer");
    $(dragObjects).draggable({  
            containment:'#decor',
            zIndex: 1000,
            revert: true,
            delay: 0,
            dragDistance: 1000,

            start: function(event, ui) {
                dragTarget = event.currentTarget; // luam date despre obiectul curent tras
                indexDrags = dragObjects.indexOf(dragTarget); // afiseaza index-ul obiectului tras
                returnSrc = $(dragTarget).children("img").prop("src");
                p = $(dragTarget).children("p").html();
            }
        });     

        $(dropObjects).droppable({
          drop: function( event, ui )
            {
                dropTarget = event.target.id; // luam date despre drop target
                indexDrops = dropTarget.charAt(dropTarget.length-1); // afiseaza index-ul dropTarget-ului
                var obj = $("#" + dropTarget).children("img");
                obj.prop("src", returnSrc);
                $("#" + dropTarget).append("<p class='texts'>" + p + "</p>");
                $(dropObjects[indexDrops]).droppable('disable');
                $(dragTarget).css("visibility", "hidden");

                DropAmount++;

                if (indexDrags !=  indexDrops){ 
                    wrongDropAmount++;
                    toChange.push(indexDrops);
                    toChange.sort();
                    console.log("to change: " + toChange);
                }
                else{
                    finalArray.push(indexDrops); 
                    finalArray.sort();
                    console.log("final array: " + finalArray);
                }

                if(DropAmount == 6){
                    checkBtn.disabled = false;
            } 
        }
    });
};

function checkAnswer(){ 
    DropAmount = DropAmount - wrongDropAmount;
    wrongDropAmount = 0;

    for(var i=0; i<finalArray.length; i++){
        for(var i=0; i<correctAnswers.length; i++){
        if(finalArray[i] == correctAnswers[i]) {
            $("#screenPartner").prop("src", "res/pixiDreapta.svg");
            $("#porumbel").prop("src", "images/happyPigeon.svg");
            $("#linieFinal").css("visibility", "visible");
            resetBtn.disabled = false;
            checkBtn.disabled = true;
            updateBubble(2);
    }
        else{
            revert();
            checkBtn.disabled = true;
            $("#screenPartner").prop("src", "res/pixiDreaptaTrist.svg");
            $("#porumbel").prop("src", "images/sadPigeon.svg");
            toChange = [];
            updateBubble(3);
            } 
        }
        }
};

function revert(){  
    for(var i=0; i < toChange.length; i++){
            if (toChange[i] ==  correctAnswers){
                $("#dropspot" + toChange[i]).children("img").prop("src", "images/drop.svg");
                $(dropObjects[toChange[i]]).children("p").hide();
                $(dragObjects[toChange[i]]).css("visibility", "visible");
                $(dropObjects[toChange[i]]).droppable('enable');
            }
    }
    return true;
};

正确的顺序是数组var correctAnswers = [0,1,2,3,4,5];并且改变存储错误索引的数组，最终数组存储正确定位的图像索引。

我需要什么：当图像定位正确以从checkanswer功能获得正确的反馈时，如果某些图像没有正确定位则是另一个，所以应该还原和其他一些东西。我在编写代码时错了吗？
