我正在开发视频播放器,其中XML是我的播放列表。这是代码:
$crxml=file_get_contents('http://spoti.com/latest.xml/?lang=en');
$rss=new SimpleXMLElement($crxml);
$playlistitem=1;
foreach($rss->channel->item as $post)
if($playlistitem<=8)
echo '<ul>';
echo '<li class="xtitle">'.$post->title.'</li>';
echo '<li class="xdesc">'.$post->description.'</li>';
$dc=$post->children('http://search.yahoo.com/mrss/');
echo '<li class="xthumb">'.$dc->thumbnail->attributes()->url.'</li>';
echo '<li class="xpreview">'.$dc->thumbnail->attributes()->url.'</li>';
echo '<li class="xsources_mp4">'.$dc->content->attributes()->url.'</li>';
$dc->content->attributes()->url=preg_replace('/.mp4/','.webm',$dc->content-attributes()->url);
echo '<li class="xsources_webm">'.$dc->content->attributes()->url.'</li>';
echo '</ul>';
$playlistitem++;
当用户点击语言时,我想用新内容替换旧内容,所有条目都替换为新条目

一个例子
if(isset($_POST["lang"]))
{
$lang = $_POST["lang"];
} else {
$lang = "eng";
}
$crxml=file_get_contents('http://spoti.com/latest.xml/?lang='.$lang);
$rss=new SimpleXMLElement($crxml);
$playlistitem=1;
foreach($rss->channel->item as $post) {
if($playlistitem<=8) {
echo '<ul id="playlist">';
echo '<li class="xtitle">'.$post->title.'</li>';
echo '<li class="xdesc">'.$post->description.'</li>';
$dc=$post->children('http://search.yahoo.com/mrss/');
echo '<li class="xthumb">'.$dc->thumbnail->attributes()->url.'</li>';
echo '<li class="xpreview">'.$dc->thumbnail->attributes()->url.'</li>';
echo '<li class="xsources_mp4">'.$dc->content->attributes()->url.'</li>';
$dc->content->attributes()->url=preg_replace('/.mp4/','.webm',$dc->content-attributes()->url);
echo '<li class="xsources_webm">'.$dc->content->attributes()->url.'</li>';
echo '</ul>';
$playlistitem++;
}
}
然后在页面上的jQuery中有一个带有语言的选择框,名为#langSelect
$('#langSelect').change( function() {
var langSelected = $(this).val();
$("#playlist").load("<?php echo $_SERVER['PHP_SELF']."?uid=".time(); ?> #playlist", {lang: langSelected});
});
要使用此调试尝试:
$('#lang').change( function() {
var langSelected = $(this).val();
alert('Selected language: '+langSelected);
var url = '<?php echo $_SERVER['PHP_SELF']."?uid=".time(); ?>';
alert('Ajax POST URL is: '+ url);
$("#playlist").load(url+" #playlist", {lang: langSelected}, function(response, status, xhr) {
alert(status);
alert(response);
}
});
});
