Instance 4:
Use the list component to create an MP3 playlist.
Create an XML document and enter Code , And then save as xml-004.xml.
Copy code The Code is as follows: <? XML version = "1.0" encoding = "gb2312"?>
<Mp3list>
<MP3 Path = "jmzcg133"> asan-Singing In loneliness </MP3>
<MP3 Path = "jmjywsls.mp3"> lonely because of who you miss </MP3>
<MP3 Path = "szwspdxd.mp3"> old wolf-brother sleeping in my upper bunk </MP3>
<MP3 Path = ".mp3"> vow-Buddha seeking </MP3>
<MP3 Path = "xyzth.pdf"> next day </MP3>
<MP3 Path = "nswdxfm.pdf"> Yi nengjing-Are you happy? </MP3>
<MP3 Path = "aqfx133"> love revival (rongzuer) </MP3>
<MP3 Path = "qrlg.mp3"> fengmu Xinnian-Autumn and Japanese love songs </MP3>
<MP3 Path = "qnyh.mp3"> Leslie Cheung-ghost </MP3>
<MP3 Path = "a.mp3"> A great English song (often played in bars) </MP3>
</Mp3list>
XML structure:
<Mp3list> top-level nodes in the XML document.
<MP3 Path = "jmzcg133"> asan-Sub-nodes under the top-level node of lonely singing </MP3>. path is the attribute under the MP3 node, "asan lonely singing" is the value of MP3 nodes.
Open flash to create a new flash document, the size of 200*150, save to the directory of the XML document just now, named as xml-04.fla. Create two layers named actions and cont respectively. In the cont layer, pull a list component to the first frame. The size is 200*150, the Instance name is mp3_list, and enter the following code in the first frame of the actions layer:
Copy code The Code is as follows: // xml-004.fla.
// Use the system code to prevent garbled characters.
System. usecodepage = true;
// Instantiate an XML object.
VaR myxml: xml = New XML ();
// Ignore spaces in the XML document during analysis.
Myxml. ignorewhite = true;
// Load the xml-004.xml documentation.
Myxml. Load ("xml-004.xml ");
// Call the XML. onload event.
Myxml. onload = function (success: Boolean)
{
// If the load is successful, success = true; otherwise, success = false;
If (SUCCESS ){
Trace ("loaded successfully! ");
// Use an array to reference the array of sublevel nodes of top-level nodes.
VaR child_arr: array = myxml. firstchild. childnodes;
// This For traversal is the sublevel 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: the node value of the XML node.
// Child_arr [I]. Attributes. path is the path attribute of the XML node.
Mp3_list.additem ({label :( I + 1) + "." + child_arr [I]. firstchild. nodevalue, data: child_arr [I]. Attributes. Path });
}
} Else {
Trace ("loading failed! ");
}
};
// The listevent function executes the change event in the list component.
Function listevent (): void
{
// This is the song address. You can use the loadsound method of the sound class to play the song. For example, mysound. loadsound (mp3_list.selecteditem.data). For details, see the help documentation.
Trace (mp3_list.selecteditem.data );
}
// Add a frame listener.
Mp3_list.addeventlistener ("change", listevent );
