我已经构建了这个使用HTML5拖放和javascript的棋盘格应用程序.它适用于chrome和firefox,但不适用于IE9或IE8.我的猜测是问题在于我如何附加事件.

        allPieces[i].addEventListener('dragstart', handlePieceDragStart, false);
}
for (var i = 0, len = allSquares.length; i < len; i++){
            allSquares[i].addEventListener('dragstart', handleDragStart, false);
            allSquares[i].addEventListener('dragenter', handleDragEnter, false);
            allSquares[i].addEventListener('dragover', allowDrop, false);
            allSquares[i].addEventListener('dragleave', handleDragLeave, false);
            allSquares[i].addEventListener('drop', handleDrop, false);  
    }
}

function eventerIE(){
    for (var i = 0, len = allPieces.length; i < len; i++){
            allPieces[i].attachEvent('dragstart', handlePieceDragStart, false);
    }
    for (var i = 0, len = allSquares.length; i < len; i++){ …
