我認爲錯誤必須與IE8和cookies操作不兼容，因爲在IE8中您可以看到密碼和登錄詢問屏幕，但是當您輸入數據併發送它的瀏覽器似乎什麼都不做，這是你可以試試我的代碼的URL：http://200.8.27.127/tiempo/teacher.phpPHP代碼適用於每個瀏覽器，但不適用於IE8
，這是代碼：

你覺得isuue可以上的JavaScript？
嘗試使用Firefox或谷歌瀏覽器的代碼firts，然後在IE8中嘗試。
document.getElementById（「charCounter」）。innerHTML = 300 - textfield.value.length; 您是否允許將innerHTML設置爲數字？它是否隱式轉換爲字符串？ 您可以嘗試： document.getElementById（「charCounter」）。innerHTML =「」+（300 - textfield.value.length）; – Chad 2010-06-10 02:20:18
它不是，我必須添加到我的問題： 嘗試用戶：djsoftlayer和密碼：1234 在Firefox中你會得到訪問，但不是在IE8 請試試這個 – DomingoSL 2010-06-10 02:50:22
