                style='z-index: 0; left: 200px; top: 90px; width: 0px; height: 0px; position: relative;'
                class="dragAble">
                <img name='imageshow' id="images1" width="560" src='./images/test.jpg' border='0'
                    onload="return imgzoom(this,600);" style="cursor: pointer;" alt="" /></div>
        </div>
    </body>
    </html>这样？

    document.getElementById("block1").style.top
    这样就行了呀。
