How to retrieve multiple anchors URLs with jQuery?
I would like to create a javascript playlist with Jplayer. This is a nice and easy tool, however I never coded with javascript.
Look at the javascript used in this demo. It uses a list to store MP3 and Ogg files :
var myPlayList = [
{name:"Tempered Song",mp3:"http://www.miaowmusic.com/mp3/Miaow-01-Tempered-song.mp3",ogg:"http://www.miaowmusic.com/ogg/Miaow-01-Tempered-song.ogg"},
{name:"Hidden",mp3:"http://www.miaowmusic.com/mp3/Miaow-02-Hidden.mp3",ogg:"http://www.miaowmusic.com/ogg/Miaow-02-Hidden.ogg"},
{name:"Lentement",mp3:"http://www.miaowmusic.com/mp3/Miaow-03-Lentement.mp3",ogg:"http://www.miaowmusic.com/ogg/Miaow-03-Lentement.ogg"},
{name:"Lismore",mp3:"http://www.miaowmusic.com/mp3/Miaow-04-Lismore.mp3",ogg:"http://www.miaowmusic.com/ogg/Miaow-04-Lismore.ogg"},
{name:"The Separation",mp3:"http://www.miaowmusic.com/mp3/Miaow-05-The-separation.mp3",ogg:"http://w开发者_如何学运维ww.miaowmusic.com/ogg/Miaow-05-The-separation.ogg"},
{name:"Beside Me",mp3:"http://www.miaowmusic.com/mp3/Miaow-06-Beside-me.mp3",ogg:"http://www.miaowmusic.com/ogg/Miaow-06-Beside-me.ogg"},
];
So for now, I just use a django template (but it could be another template engine) to create this variable. However I would like to create this list (myPlayList) dynamically with a javascript function which would retrieve the MP3 urls and the Ogg vorbis URLs from the HTML code.
Thus, from this HTML code...:
<body>
<article id="track-0">
<h1>lorem ipsum</h1>
<ul>
<li><a href="...">Mp3</a></li>
<li><a href="...">Vorbis</a></li>
<li><a href="...">Flac</a></li>
</ul>
</article>
<article id="track-1">
<h1>lorem ipsum</h1>
<ul>
<li><a href="...">Mp3</a></li>
<li><a href="...">Vorbis</a></li>
<li><a href="...">Flac</a></li>
</ul>
</article>
<article id="track-2">
<h1>lorem ipsum</h1>
<ul>
<li><a href="...">Mp3</a></li>
<li><a href="...">Vorbis</a></li>
<li><a href="...">Flac</a></li>
</ul>
</article>
</body>
... I need to build a javascript list like this (where each index of the list represents the track-ID in the HTML:
var files = [
{mp3:"...", ogg:"..."},
{mp3:"...", ogg:"..."},
{mp3:"...", ogg:"..."},
];
Please excuse me for my ugly english. If you need more informations just tell me.
Thank you. :-)
This can be done in many ways, the following being one possibility:
var files = [];
$('article').each(function() {
files.push({
mp3: $('li:nth-child(1) a', this).attr('href'),
ogg: $('li:nth-child(2) a', this).attr('href')
});
});
I would add a class to each link, ex:
<a class="mp3_link" href="...">Mp3</a>
Then, you could do something like:
$("article").each(function() {
var mp3_url = $("a.mp3_link", this).attr('href');
// Keep going and build your data structure
});
加载中,请稍侯......
