Html中的comment其实也有nodeType的，只是我们一直不用罢了。它的nodeType = 8哦。于是，就有了一个基于jQuery的插件：comments

- // This jQuery plugin will gather the comments within

- // NOTE: Comments are wrapped in DIV tags.
- jQuery.fn.comments = function( blnDeep ){
- var blnDeep = (blnDeep || false);
- var jComments = $( [] );
- // Loop over each node to search its children for
- // comment nodes and element nodes (if deep search).
- this.each(
- function( intI, objNode ){
- var objChildNode = objNode.firstChild;
- var strParentID = $( this ).attr( "id" );
- // Keep looping over the top-level children
- // while we have a node to examine.
- while (objChildNode){
- // Check to see if this node is a comment.
- if (objChildNode.nodeType === 8){
- // We found a comment node. Add it to
- // the nodes collection wrapped in a

代码其实并不多，大概知道就好，本来是用phpQuery也这样写的。但发现。。。stick的时候，即使我选择了nodeType=8也取不到值。我晕啊，最后我只能用正则将注释取出来当成内容用了。
早先有人把代码扔在textarea里，用来当成数据加载，现在也有人开始无耻的利用注释了。真不厚道
