在 document.ready、jquery 中调用函数
我有这样的代码
<script>$(document).ready(function(){
var myPlayList = [];
//document.write(whatTo);
//New instance of jPlayerSkin
var skin = new jPlayerSkin( '#jplayer_container' , myPlayList );
//Start the player
skin.initialize();
});
</script>
，并且有函数，即 function updatePlaylist(song,title,url) { /* code */ }
现在我想要的就是在 document.ready 中执行此 updatePlaylist 函数因为在这个函数中我还调用了 Skin.add() ，它仅在 document.ready 中可用。但是当我将函数放在 document.ready() 中时，我无法执行它，如果我将它放在外面，我可以执行该函数，但它无法访问 Skin.add() 。
i have a code like this
<script>$(document).ready(function(){
var myPlayList = [];
//document.write(whatTo);
//New instance of jPlayerSkin
var skin = new jPlayerSkin( '#jplayer_container' , myPlayList );
//Start the player
skin.initialize();
});
</script>
and i have function , which is function updatePlaylist(song,title,url) { /* code */ }
Now all i want is to execute this updatePlaylist function in document.ready because in this function i also call skin.add() , which is available in document.ready only. But when i place the function in document.ready() , i can't execute it, and if i put it outside, i can execute the function but it can't access skin.add().

将
var myPlayList = [];和var Skin = null移到文档之外。准备好后，使用updatePlaylist(song,title,url)重试>在文档中.readymove
var myPlayList = [];andvar skin = nulloutside of the document.ready, try again withupdatePlaylist(song,title,url)in document.ready不要将该函数放在传递给
document.ready的函数内，这只会在本地作用域。将其保留为全局并从该函数中调用它。
Don't put the function inside the function you pass to
document.ready, that will just locally scope it.Keep it as a global and just call it from that function.
