Animating a swap of cells in a table on click using JQuery

Question

I'm trying to make a simple flash-card game in JavaScript using JQuery. In one part of the game, you should click on a row in a "table" ( tablica ) made out of div s ( tablica[i][j] ) to swap the cells in that row (to put the content in the cell in the correct column). Here is the relevant piece of code:

for (var j=0; j<odgovor1.length; j++)
            for (var i=1; i<3; i++)
            {
                tablica[i][j]=document.createElement("div");
                tablica[i][j].setAttribute("class","rijecUDrugomDijelu");
                if (i===1) tablica[i][j].appendChild(document.createTextNode(odgovor1[j]));
                else if (i===2) tablica[i][j].appendChild(document.createTextNode(odgovor2[j]));
                tablica[i][j].style.top=228+27*j;
                tablica[i][j].style.left=-153+110+153*i;
                tablica[i][j].onclick=eval(
                        "(function()"+
                        "{"+
                        "var tmp=tablica[1]["+j+"].style.left;"+
                        "tablica[1]["+j+"].style.left=tablica[2]["+j+"].style.left;"+
                        "tablica[2]["+j+"].style.left=tmp;"+
                        "tmp=odgovor1["+j+"];"+
                        "odgovor1["+j+"]=odgovor2["+j+"];"+
                        "odgovor2["+j+"]=tmp;"+
                        "})"
                        );
                pozadina.appendChild(tablica[i][j]);
            }

When the user clicks on a row in that table, the cells in that row are swapped, and the content of the table is correctly tracked in the string arrays odgovor1 and odgovor2 . However, they are swapped without any animation, they are swapped immediately. When I try to apply JQuery animations to the cells ( div s) tablica[1][j] and tablica[2][j] , the program crashes. Do you know how to do that properly?
Again, I assure you, the code above works well now, but when I try to use JQuery animations instead of simply swapping the properties style.left , it crashes.

Using object properties instead of eval appears to work:

for (var j=0; j<odgovor1.length; j++)
            for (var i=1; i<3; i++)
                    {
                    tablica[i][j]=document.createElement("div");
                    tablica[i][j].setAttribute("class","rijecUDrugomDijelu");
                    if (i===1) tablica[i][j].appendChild(document.createTextNode(odgovor1[j]));
                    else if (i===2) tablica[i][j].appendChild(document.createTextNode(odgovor2[j]));
                    tablica[i][j].style.top=228+27*j;
                    tablica[i][j].style.left=-153+110+153*i;
                    tablica[i][j].redak=j;
                    tablica[i][j].onclick=
                            function()
                            {
                            var tmp=tablica[1][this.redak].style.left;
                            $(tablica[1][this.redak]).animate({left:(tablica[2][this.redak].style.left)},500);
                            $(tablica[2][this.redak]).animate({left:(tmp)},500);
                            tmp=odgovor1[this.redak];
                            odgovor1[this.redak]=odgovor2[this.redak];
                            odgovor2[this.redak]=tmp;
                            }
                    pozadina.appendChild(tablica[i][j]);
                    }
