Hello @JScript,
Perfect code especially for communities which are using codes.
Very useful.

Ah yes this is the code you developed to help with my phpbb2/conflicting avacweb coding problem. Works great and has been very helpful. Thanks again for this lovely code and feature JScript .

Very nice i like this new selection code!

I also wrote code to count the number of lines. My way is count br tag length and create numbered columns.

Code:

$("code").each(function() {
   var $this = $(this),
      lines = $("br", $this).length,
      i,
      $numbers = $("<div>", {
         "class": "lineNumber"
      }).insertBefore($this);

   for (i = 0; i <= lines; i++) {
      $numbers.append($("<span>", {
         text: (i + 1)
      }));
   }
});

I have written code discrimination 3 types of code html, css and js. Maybe it would be helpful if you want highlight codes. http://jsfiddle.net/baivong/v6WUw/

@Zzbaivong
His method is manual, my method is done automatically with < ol > tag!

Imagine having to enumerate codes on a topic that contains 10 threads and each contain a 800 code lines!!!

What do you mean? Numbering or performance issues?

@Zzbaivong
Performance! Compare your way of numbering with my ...

JS

First test:

Code:

console.time("jScript");
var tagCode = jQuery('.cont_code, code'),
   codebox = null;

for (var i = 0, len = tagCode.length; i < len; i++) {
   codebox = jQuery(tagCode[i]).closest('.codebox');
   codebox.before(
      '<pre class="jsCode_block">' +
      '  <ol class="linenums">' + tagCode[i].innerHTML.replace(/<br>/mg, '<li class="L1"><span>') + '</ol>' +
      '</pre>'
   );
   codebox.remove();
}
console.timeEnd("jScript");
>> jScript: 7.25 ms

Code:

console.time("baivong");
$("code").each(function() {
   var $this = $(this),
      lines = $("br", $this).length,
      i,
      $numbers = $("<div>", {
         "class": "lineNumber"
      }).insertBefore($this);

   for (i = 0; i <= lines; i++) {
      $numbers.append($("<span>", {
         text: (i + 1)
      }));
   }
});
console.timeEnd("baivong");
>> baivong: 28.79 ms

@JScript won  

Then I have revised my codes and test again:

Code:

console.time("baivong");
$("code").each(function() {
   var $this = $(this),
      lines = $("br", $this).length,
      i, arr = [],
      $numbers = $("<div>", {
         "class": "lineNumber"
      }).insertBefore($this);

   for (i = 0; i <= lines; i++) {
      arr[i] = '<span></span>';
   }
   $numbers.html(arr.join(''));
});
console.timeEnd("baivong");
>> baivong: 2.45 ms

console.time("baivong");
var code = document.getElementsByTagName("CODE"),
    codeLength = code.length;
for (var i = 0; i < codeLength; i++) {
    var codeEach = code[i],
        lines = codeEach.getElementsByTagName("BR").length,
        arr = [];
    var linesBlock = document.createElement("div");
    linesBlock.className = "lineNumber";
    codeEach.parentNode.insertBefore(linesBlock, codeEach);
    for (var j = 0; j <= lines; j++) {
        arr[j] = '<span></span>';
    }
    linesBlock.innerHTML = arr.join('');
}
console.timeEnd("baivong");
>> baivong: 1.97 ms

I won

This code is awesome. Thank you, JScript!
