對不起,我再次提出同樣的問題,因爲我沒有明確提出問題,所以沒有人能夠幫助我澄清昨天的困惑。這裏是codepen(似乎無法在ie8中打開)。我想要拖動'move-obj',但它在IE瀏覽器(8,9,10)中不起作用(如果在後臺有圖像)。我怎樣才能使這個演示工作在IE8以上的IE瀏覽器?如果在背景中有圖像,不能不選擇IE中的元素

向元素應用'higher z-index'試試這個...它工作正常你期望什麼? – guradio

它仍然不起作用@guradio – yzajoee

不要重複提出問題,如果您在原始文章中「_沒有明確提出問題」_,那麼編輯原文更加清晰。 –

只需設置一個透明圖像的.move-obj背景或代替透明圖像嘗試將其設置爲url(about:blank)也應該工作。

好主意,謝謝 – yzajoee
