i'm working on html javascript for room visualizer when displaying image on ui level, and getting data from Q4 parameter in function i'm not able to resolve please help me out ASAP

Script-2.js

function selectTile(tiles) {
    if(activeShape != null){
        selectShape(tiles[0].id);     
    } else {
        setTile(tiles[0].tile_type,tiles,function(tid,tile_data)
        {
            console.log_(tid,tile_data);
            var layoutType = $('.layout-type-input[data-tile-id=' + tid + ']:checked').val() || "grid";

            if(layoutType=="dragdrop")
            {
                var td=tile_data[0];
                var i=free_tiles[tid].indexOf(td);
                if(i==-1)
                    free_tiles[tid].push(td);
                free_tiles_cur[tid]=td;
            }
