Use Flash and XML to build Forum instances (2)

3. view the text

View the body, that is, the server receives the ID number sent from the Flash end, queries the database based on the ID number, and returns the query result to the Flash end in XML format.

A. Passed XML

1. Request Message

<FILE> <ID> ID of the topic to be viewed </ID> </FILE>

2. Response Message

<FILE id = "id" title = "topic" author = "author" content = "content" reply = "reply content"> </FILE>

B. Flash end

1. Create ten buttons in the second frame scenario, the instance names are "filebtn1", "filebtn2", "filebtn3", "filebtn4", "filebtn5", "filebtn6", "filebtn7", "filebtn8", and "filebtn9" and "filebtn10 ". The placement position and display content 2 are shown.

2. Add the following statement to the Action Script panel of Button filebtn1:

On (release ){
FileXml1 = new XML (); file: // Note 1
FileElement1 = fileXml1.createElement ("FILE"); file: // comment 2
IdElement1 = fileXml1.createElement ("ID"); file: // comment 3
IdNode1 = fileXml1.createTextNode ("id ");
IdNode1.nodeValue = _ root. fileId1;
IdElement1.appendChild (idNode1); file: // comment 4
FileElement1.appendChild (idElement1 );
FileXml1.appendChild (fileElement1 );
_ Root. fileNowId = _ root. fileId1; file: // comment 5
FileRepley1 = new XML ();
FileRepley1.onLoad = onFileReply1; file: // Note 6
Function onFileReply1 (filesuccess1 ){
If (filesuccess1 ){
_ Root. filetxt = fileRepley1.firstChild. attributes. title + fileRepley1.firstChild. attributes. author + response. attributes. content + fileRepley1.firstChild. attributes. reply; file: // comment 7
_ Root. gotoAndPlay ("content ");
}
}

<%
Set MyFileObject = Server. CreateObject ("Scripting. FileSystemObject") 'comment 1

Set objid = objdom.doc umentElement. SelectSingleNode ("// FILE/ID") 'comment 5
Id = objid. text

'Judge

%>

Note 1: create a temporary file object.

NOTE 2: Write the XML string from the Flash end to a temporary file.

NOTE 3: Create an XML object.

Note 4: import the XML string sent from Flash to an XML object.

Note 5: Read the content of the // FILE/ID node in the XML object.

Note 6: Create An ADO connection for a database.

Note 7: Construct an SQL string and query the database based on the sent ID.

Note 8: if a qualified record exists, read the corresponding record.

Note 9: the query condition for the reply post is Fid, so you need to query the database again.

Note 10: Construct the query records into a string.

Note 11: the pointer of the record set is moved down one step.

Note 12: Construct an XML string and send it to the Flash end.
