我的表單上有兩個輸入，當文檔加載時我想更改其值。文檔加載後無法處理輸入「更改」事件或值
這是我的代碼：
<?php
$base = dirname(dirname(__FILE__));
include($base."/include/db.php");
?>

<p>Once you have followed the link we provided in the email, you will see your signature displayed fully on your device's web browser.</p>
<p>Simply highlight all of your signature and copy it to your device's clipboard as demonstrated below.</p>

<p>Great! We've copied your signature and it is now ready to be installed!</p>
<p>We just need to find your mail's signature settings.</p>
<p>These are located at <b>Settings -> Mail, Contacts, Calendars -> Signature</b>

<h3>Installing your signature</h3>

<p><h2>Installing your signature</h2></p>
<p>Now that we have your signature settings open, you'll find an empty box ready for your signature to be pasted.</p>
<p>So all you need to do now is paste what we copied earlier into the box.</p>
<p><img src="../img/install/iphone_5.png" width="320px" height="480px"></p>
<p>One final thing you'll need to do is give your phone a quick shake to undo any of the modifications that your device will attempt to make to your signature's HTML code.</p>
<p>This is necessary for your signature to appear <i>exactly</i> how it appeared when you opened it.</p>

這是行不通的。
但是，我在Chrome的控制檯中複製了相同的代碼，並且它完美地工作。我唯一的假設是，在文檔加載完成後，這些控件會與Bootstrap/jQuery混淆和/或重新創建。
但我不知道在哪裏或爲什麼，或我該怎麼辦。
你有什麼應該可以正常工作 - 除了在文檔準備處理程序上缺少''''，儘管我認爲這只是一個錯誤的問題。你有沒有檢查過「email」和「pin」設置是否正確？控制檯中有任何錯誤？當頁面加載時，你確定'＃email'和'＃pin'元素在DOM中可用嗎？你能舉出一個問題的例子嗎？ –
我用整個代碼更新了它。看一看。 – ThePerplexedOne
