我已经搜索过了,但似乎无法理解我找到的答案。感谢任何帮助!!
目标:在section#info中列出的消息头下面的section#details中显示选定消息的详细信息。
问题:
- 下面的代码警告一个结果,但不会fadeIn();,(或show();,或…任何)。 下面的代码只抓取PHP while循环中最后一个结果的值。
php/html/jquery javascript:
<section id="info">
<?php
$user = $session->username;
$q = sprintf("SELECT * FROM mail WHERE UserTo = '%s' ORDER BY SentDate DESC",
mysql_real_escape_string($user));
$getMail = mysql_query($q, $link) or die(mysql_error());
if(mysql_num_rows($getMail) == 0) {
echo "<p>you have no mail</p>";
}
else {
?>
<form id="inbox" class="mail">
<fieldset>
<ul>
<li style="border: 2px solid purple; width: 100%;">
<span style="display: inline-block; border: 1px solid black; width: 8%; margin-left: 13%;">Status</span>
<span style="display: inline-block; border: 1px solid black; width: 15%;">From</span>
<span style="display: inline-block; border: 1px solid black; width: 45%;">Subject</span>
<span style="display: inline-block; border: 1px solid black; width: 16%;">Time</span>
</li>
<?php
while($mail = mysql_fetch_object($getMail)) {
$status = $mail->status;
$mailId = $mail->mail_id;
$from = $mail->UserFrom;
$subject = $mail->Subject;
$received = $mail->SentDate;
$theMessage = $mail->Message;
?>
<li class="outerDiv" style="border: 2px dotted purple;">
<button style="display: inline;" class="viewButton">View</button>
<button style="display: inline;">Delete</button>
<?php
echo "<span style='border: 1px solid red;'>" . $mail_id . "</span>";
echo "<span style='display: inline-block; width: 8%; border: 1px solid red;'>" . $status . "</span>";
echo "<span style='display: inline-block; width: 15%; border: 1px solid red;'>" . $from . "</span>";
echo "<span style='display: inline-block; width: 45%; border: 1px solid red;'>" . $subject . "</span>";
echo "<span style='display: inline-block; font-size: x-small; width: 17%; border: 1px solid red;'>" . $received . "</span>";
?>
</li>
<?php }
} ?>
</ul>
</fieldset>
</form>
</section>
<section id="details">
<div class="theMessage" style="display: none;"><?php echo $theMessage; ?></div>
<script type="text/javascript">
$(document).ready(function() {
$(".outerDiv").click(function(e) {
if($(e.target).is(".viewButton")) {
alert($(document).find(".theMessage").text()); //this works
$(document).find(".theMessage").text().fadeIn(1000); //this doesn't work
var theMessage = $(document).find(".theMessage").text();
theMessage.fadeIn(1000); //this doesn't work
}
});
return false; (sometimes prevents default..sometimes not?
});
</script>
</section>
注。疯狂的颜色和边框是临时布局的目的。此外,删除按钮显然会有功能…等我弄明白了。
代替
$(document).find(".theMessage").text().fadeIn(1000);
使用$('.theMessage').fadeIn(1000);
Starx是对的,但我想我也会给出一个解释。
$('.theMessage').fadeIn(1000);
如果你不明白为什么,看看http://api.jquery.com/text/。text()方法只返回一个字符串,而不是可以操作的实际HTML元素(在本例中为fadeIn)。所以text()对于获取或设置元素的内容是很好的,但是要创建动画,你需要直接调用$('. themessage ')元素上的方法。
