Example 4:
Use the list component to make a MP3 playlist.
Create a new XML document, enter the following code in Notepad, and save it as Xml-004.xml.
Copy Code code as follows:
<?xml version= "1.0" encoding= "gb2312"?>
<mp3List>
<mp3 path= "Jmzcg.mp3" > Asan-Loneliness in singing </mp3>
<mp3 path= "Jmjywsls.mp3" > Loneliness is because of missing who </mp3>
<mp3 path= "Szwspdxd.mp3" > Old Wolf-sleeping on my upper bunk brother </mp3>
<mp3 path= "Qf.mp3" > Oath-Seek Buddha </mp3>
<mp3 path= "Xyzth.mp3" > Next Stop Days </mp3>
<mp3 path= "Nswdxfm.mp3" > Yi Jing-you are my happiness </mp3>
<mp3 path= "Aqfx.mp3" > Love Renaissance (Joey) </mp3>
<mp3 path= "Qrlg.mp3" > Mu-Autumn Sonata </mp3>
<mp3 path= "Qnyh.mp3" > Leslie Cheung-Qian Female Ghosts </mp3>
<mp3 path= "A.mp3" > A great English song (often put in bars) </mp3>
</mp3List>
XML Structure:
<mp3list>xml the top-level node in the document.
<mp3 path= "Jmzcg.mp3" > Asan-Loneliness in singing </mp3> child nodes under the top-level node, path is the attribute under the MP3 node, "Asan-loneliness in singing" is the MP3 node value.
Open Flash Create a new flash document, size 200*150, saved to the directory of the XML document just now, named Xml-04.fla. New 2 layers Name the actions, Cont, and the Cont layer to pull a list component to the first frame. The size is 200*150, the instance name is the first frame of the mp3_list,actions layer, enter the following code:
Copy Code code as follows:
Xml-004.fla.
Use system encoding. Prevent garbled characters.
System.usecodepage = true;
Instantiates an XML object.
var myxml:xml = new XML ();
Whitespace in an XML document is ignored during profiling.
Myxml.ignorewhite = true;
Loads the Xml-004.xml document.
Myxml.load ("Xml-004.xml");
Invokes the Xml.onload event.
Myxml.onload = function (Success:boolean)
{
If the load succeeds, success=true; otherwise success=false;
if (success) {
Trace ("Load succeeded!");
Use an array to refer to an array of neutron-level nodes of the top-level node.
var child_arr:array = myxml.firstChild.childNodes;
This for traversal is a child node under the top-level node.
for (var i = 0; i<child_arr.length; i++) {
Add the song to the list component.
Child_arr[i].firstchild.nodevalue This is the node value of the XML node.
Child_arr[i].attributes.path This is the path attribute under the XML node.
Mp3_list.additem ({label: (i+1) + "." +child_arr[i].firstchild.nodevalue, Data:child_arr[i].attributes.path});
}
} else {
Trace ("Load failed!");
}
};
The Listevent function is to perform the Change event in the list component
function Listevent (): Void
{
This is the song address. Use the Loadsound method of sound class to play the song. Example: Mysound.loadsound (mp3_list.selectedItem.data); see the help documentation for details.
Trace (Mp3_list.selectedItem.data);
}
Add a frame listener.
Mp3_list.addeventlistener ("Change", listevent);
