jQuery .slideUp问题
.slideDown工作正常。 第二次单击链接时，会再次出现.slideDown动画而不是.slideUp。 请帮我一把 谢谢。
$(document).ready(function() { $('#toggleButton').click(function() { if ($('#toggleSection').is(":hidden")) { $('#toggleSection').slideDown("slow"); } else { $('#toggleSection').slideUp("slow"); } return false; }); }); 以下是整个模块的代码。 这个php包含在主页面上，其中还包含页眉和页脚。
11) { $phone = substr($phone, 0, 11); } // Do we want to convert phone numbers with letters to their number equivalent? // Samples are: 1-800-TERMINIX, 1-800-FLOWERS, 1-800-Petmeds if ($convert == true && !is_numeric($phone)) { $replace = array('2'=>array('a','b','c'), '3'=>array('d','e','f'), '4'=>array('g','h','i'), '5'=>array('j','k','l'), '6'=>array('m','n','o'), '7'=>array('p','q','r','s'), '8'=>array('t','u','v'), '9'=>array('w','x','y','z')); // Replace each letter with a number // Notice this is case insensitive with the str_ireplace instead of str_replace foreach($replace as $digit=>$letters) { $phone = str_ireplace($letters, $digit, $phone); } } $length = strlen($phone); // Perform phone number formatting here switch ($length) { case 7: // Format: xxx-xxxx return preg_replace("/([0-9a-zA-Z]{3})([0-9a-zA-Z]{4})/", "$1-$2", $phone); case 10: // Format: (xxx) xxx-xxxx return preg_replace("/([0-9a-zA-Z]{3})([0-9a-zA-Z]{3})([0-9a-zA-Z]{4})/", "($1) $2-$3", $phone); case 11: // Format: x(xxx) xxx-xxxx return preg_replace("/([0-9a-zA-Z]{1})([0-9a-zA-Z]{3})([0-9a-zA-Z]{3})([0-9a-zA-Z]{4})/", "$1($2) $3-$4", $phone); default: // Return original phone if not 7, 10 or 11 digits long return $OriginalPhone; } } } // Has the form been submitted? if (isset($_POST['submit-add_student'])) { // Convert the instrument and teacher to IDs $resultIns = mysql_query("SELECT i_ID FROM instrument WHERE instrument_name = '$_POST[instrument]'"); $instID = mysql_fetch_row($resultIns); $instID = $instID[0]; $resultTeach = mysql_query("SELECT f_ID FROM faculty WHERE last_name_fac = '$_POST[teacher]'"); $facID = mysql_fetch_row($resultTeach); $facID = $facID[0]; // Seperate first and last name $names = "$_POST[last_name]"; $namesArray = explode(" ", $names); $firstName = $namesArray[0]; $lastName = $namesArray[1]; // The actual insert command $ins = "INSERT INTO students (s_ID, last_name, first_name, phone, email_stu, instrument, teacher, year) VALUES (s_ID,'$lastName','$firstName','$_POST[phone]','$_POST[email_stu]','$instID','$facID','$_POST[year]')"; $resultStu = mysql_query($ins); if(!$resultStu) { die('Error: ' . mysql_error()); } echo ''; echo 'window.location="index.php"'; echo ''; } // Has the DELETE form been submitted? if (isset($_POST['submit_delete-stu'])) { // The actual delete command $stuDelete = "DELETE FROM students WHERE s_ID = '$_POST[ID]'"; $resultStuDelete = mysql_query($stuDelete); if(!$resultStuDelete) { die('Error: ' . mysql_error()); } echo ''; echo 'window.location="index.php"'; echo ''; } // Toggle the display order $order = $_GET['order']; if (empty($order)) { $orderBy="ASC"; $order="down"; } else { if ($order=="up") { $orderBy="ASC"; $order="down"; } elseif ($order=="down") { $orderBy="DESC"; $order="up"; } } // Change the sort parameter $sort = $_GET['sort']; if (empty($sort)) { $sort="students.last_name"; } else { switch ($sort) { case "name": $sort="students.last_name"; break; case "phone": $sort="phone"; break; case "email": $sort="email_stu"; break; case "inst": $sort="instrument"; break; case "teacher": $sort="teacher"; break; case "year": $sort="year"; break; } } // Display the table header links echo ""; echo ""; echo "Name"; echo ($sort=="students.last_name") ?

根据评论我认为重要的是要注意live()是折旧的：
live（）现在已经折旧（从1.7开始，从1.8开始删除）。 你应该像on（）那样使用（例子）：$（document）.on（“click”，“＃turngButton”，function（）{}）;. 您可以缩小文档范围，只要它在页面加载时作为DOM元素存在即可。 文档
我会使用.slideToggle（）来解决这个问题。 不要把它与姐姐混淆.fadeToggle（）
$(document).ready(function() { $('#toggleButton').click(function() { $('#toggleSection').slideToggle('slow'); }); });
更少的代码，并做同样的事情，对。

我在livexample中使用过
Bacon ipsum dolor sit amet pork chop magna pork, tempor in jowl ham labore rump tenderloin pariatur pancetta tri-tip pork loin. Spare ribs meatloaf ground round chicken, non esse cow.
看着你的实际代码，我无法复制问题。 http://jsfiddle.net/zXwRB/我在chrome 12.0.742.91和firefox 3.6中试过这个
UPDATE
根据你的评论，我想知道将它包装在.live（）中是否是正确的方法。
$(document).ready(function() { $('#toggleButton').live('click', function() { $('#toggleSection').slideToggle('slow'); }); });
不幸的是，如果没有看到更多代码，可能很难说。
由于API中的以下段落，我建议使用.live()
.live（）方法能够通过使用事件委托来影响尚未添加到DOM的元素：绑定到祖先元素的处理程序负责在其后代上触发的事件。 传递给.live（）的处理程序永远不会绑定到元素; 相反，.live（）将一个特殊的处理程序绑定到DOM树的根。
如果您可能稍后通过PHP添加项目可能会有一些冲突….这是我最好的猜测，而不会看到代码。
您也可以仅使用toggle而不是slideToggle 。
