My QQ: 5642382. My QQ group: 2577162

Function: when posting a post, use the [php] php code [/php] Mark to highlight the php code,
Use the [runcode] Html code [/runcode] Mark to run HTML code (running non-server on the client ).

To add a plug-in, follow these steps:
1. Modify include/common. js
Search
Function copycode (obj ){
Var rng = document. body. createTextRange ();
Rng. moveToElementText (obj );
Rng. scrollIntoView ();
Rng. select ();
Rng.exe cCommand ("Copy ");
Rng. collapse (false );
}
Add the following at the end of the function:

[Copy to clipboard] [-] CODE:
Function runCode (obj ){
Var winname = window. open (''," _ blank ",'');
Winname.doc ument. open ('text/html ', 'replace ');
Winname.doc ument. writeln (obj. value );
Winname.doc ument. close ();
}

Function saveCode (obj ){
Var winname = window. open ('', '_ blank', 'top = 10000 ');
Winname.doc ument. open ('text/html ', 'replace ');
Winname.doc ument. writeln (obj. value );
Winname.document.execcommand('saveas', '', 'code.htm ');
Winname. close ();
}
2. Modify include/discuzcode. func. php
Search

[Copy to clipboard] [-] CODE:
$ Discuzcodes ['codecs'] ++;
Return "[\ tDISCUZ_CODE _ $ discuzcodes [pcodecount] \ t]";
}
(Note: You can also use Editplus to directly find the 110th lines of code to add the following code)
Continue to add below:

3. Continue to modify include/discuzcode. func. php
Search

$ Message = preg_replace ("/\ s * \ [code \] (. + ?) \ [\/Code \] \ s */ies "," codedisp ('\ 1') ", $ message );
Add the following content:
