當自動完成文本框展開並且用戶滾動瀏覽器頁面時,框保持在相同的位置並且不會消失。如果它保持在同一位置,我可以開放,但我不明白它爲什麼會停留在同一個位置。jQuery自動完成框在滾動時保持打開並處於相同位置

任何鏈接/的jsfiddle /代碼,您是否可以提供?像這樣的問題不能真正回答。 – elclanrs 2012-02-04 04:50:26
我添加了代碼,雖然它的格式不正確,我試圖解決這個問題,所以我不花時間在那... – kav 2012-02-04 05:12:02
你正在使用哪個'autocomplete plugin';有很多外面。請提及插件鏈接atleast – diEcho 2012-02-04 06:59:28
