另一個問題，我發佈關於我與PHP頁面的問題我正在對一些人的工作評論告訴我，我正在使用textarea標記作爲自我關閉標記，這是導致我所有的問題。我知道比這樣做更好，所以它讓我雙重和三重檢查我的編碼，正如我已經預料的那樣，標籤已關閉。下面是它在Dreamweaver中的圖片瀏覽器如何將我的textarea標籤變成自閉標籤？
所以剛開始我沒有線索，他們在談論，但在在開發的Chrome瀏覽器工具檢查它，我看到了這一點
因此，瀏覽器以某種方式將自己的textarea標籤更改爲自閉標籤。它是如何做到這一點，我該如何阻止它？到目前爲止，據我所知，它只對這裏列出的textarea有效。我的調查問卷的完整版本中有更多，據我所知，他們都表現良好。這是什麼引發了這種事情發生？
///////////////////////////////////// UPDATE //////// //////////////////////////
確定我右點擊並選擇「查看源」和「檢查元件」和它的確示出textarea標籤被渲染成一個自閉標籤。我發佈的第一張照片是「檢查元素」選項，這裏是「查看源」選項。
所以是.....莫名其妙它越來越交換了我和它吃的PHP文件的其餘部分一路走過來關閉HTML標記。感謝所有yoru幫助到目前爲止，希望我們可以得出這個想法，我花了3天的時間才發現這是問題，我最初從我的.js文件中得到一個錯誤，說onclick函數不能爲null，我的語法很完美。它是這樣回來的，因爲它吞噬了它試圖提及的因素，所以沒有什麼東西可以適用於它。
/////////////////////////////// UPDATE 2 ///////////// ////////////////////////
OK我曾經在W3.org的驗證的建議，這就是它掀開
我拿出PHP數據，以防止它來了作爲一個錯誤。但這是我在Dreamweaver中的。

我也通過PHP驗證器運行它，並得到0錯誤。我嘗試在textarea標籤之間放置文本，似乎阻止了它的發生，但是我在textarea裏面找到了信息，我在這裏發現了另一個帖子，他們說這裏放置了>，但我也能看到，而且我不認爲任何事情都適用於我正在做的任何事情。
是否錯誤，並在任何這種編碼的幫助棚子光？
嘗試通過w3c驗證程序運行整個頁面。作爲結果，textarea有什麼問題？ – charlietfl
如果您在標籤之間放置文本，開發工具會顯示什麼內容？ –
看着張貼在之前的問題頁面有身體和頭部之間的無效的標記 – charlietfl
