試試這個:http://shaquin.tk/experiments/select-ajax2.html。
HTML:
<select name="select-choice" id="select-choice">
<optgroup label="News">
<option value="feature">Feature</option>
<option value="current">Current</option>
<option value="research">Research</option>
</optgroup>
<optgroup label="Archive">
<option value="archive">Archive</option>
</optgroup>
<optgroup label="Video">
<option value="video">Video</option>
</optgroup>
<optgroup label="Submit">
<option value="story">Story</option>
<option value="event">Event</option>
</optgroup>
</select>
<div id="article">Please select an article to view.</div>
JS:
var origText = '';
$(document).ready(function() {
origText = $('#article').text();
$('select').on('change', changed);
});
function changed(e) {
$('#article').html('<span class="loading">Loading...</span>');
$('#article').load('content.php', $.param({0: e.target.value, 1: origText}));
}
PHP:
<?php
$selected = $_GET[0];
$articles = array(
'' => $_GET[1],
'feature' => 'Feature article goes here',
'current' => '<p>Lorem ipsum dolor sit amet, denique laetare ... se est Apollonius.</p>',
'research' => 'You selected <code>research</code>',
'archive' => 'Archives',
'video' => '<div style="font-size:48pt;font-weight:bold;font-style:italic;background:red;text-align:center;padding:20px;margin:10px;border-radius:20px;-moz-border-radius:20px;-webkit-border-radius:20px;">Video</div>',
'story' => 'Submit a story',
'event' => 'Submit an event'
);
$article = $articles[$selected];
echo $article;
?>
CSS(選擇有理):
body {
background: #ccc;
text-align: center
}
#article {
padding: 30px;
margin: 20px;
text-align: left;
background: #eee;
text-shadow: 1px 1px #fff;
text-shadow: 0 0 3px #fff;
border-radius: 8px;
-moz-border-radius: 8px;
-webkit-border-radius: 8px;
}
.loading {
text-transform: uppercase;
font-size: 15pt;
text-shadow: 1px 1px #f00, 1px 2px #f00, 2px 2px #f00, 3px 3px #f00;
}
在PHP中,你可能會想獲取從數據庫中文字:PHP - MySQLi。
沒有人會爲您編寫代碼。查看一些[jQuery教程並閱讀文檔](http://docs.jquery.com/Main_Page),並在遇到特定問題或問題時回來。 – 2012-07-12 22:09:12
究竟是什麼問題?我的帖子中沒有看到問題。 – jmoerdyk 2012-07-12 22:10:53
我只是想要開始。你能指定我確切的地方看jQuery網站嗎? – ak1481 2012-07-12 22:12:05
