基于jQuery的为attr添加id title等效果的实现代码

核心代码:复制代码代码如下:<script language="javascript" type="text/javascript"> $(document).ready(function(){ //$('div.chapter a').attr({'rel':'external'}); $('div.chapter a').each(function(index){ var $linkthis=$(this) $linkthis.attr({ 'rel':'external', 'id':'wikilink-'+index, 'title':'你好，现在在试验'+$linkthis.text() }); }); $('#wikilink-1').css('fontSize',33); }); </script> 完整测试代码：复制代码代码如下:<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>DOM Manipulation</title> <script language="javascript" src="http://demo.jb51.net/jslib/jquery/jquery-1.5.2.min.js"></script> <script language="javascript" type="text/javascript"> $(document).ready(function(){ //$('div.chapter a').attr({'rel':'external'}); $('div.chapter a').each(function(index){ var $linkthis=$(this) $linkthis.attr({ 'rel':'external', 'id':'wikilink-'+index, 'title':'你好，现在在试验'+$linkthis.text() }); }); $('#wikilink-1').css('fontSize',33); }); </script> </head> <body>  <h1 id="f-title">Flatland: A Romance of Many Dimensions</h1> <div id="f-author">by Edwin A. Abbott</div> <h2>Part 1, Section 3</h2> <h3 id="f-subtitle">Concerning the Inhabitants of Flatland</h3> <div id="excerpt">an excerpt</div> <div class="chapter"> <p class="square">Our Professional Men and Gentlemen are Squares (to which class I myself belong) and Five-Sided Figures or <a href="http://en.wikipedia.org/wiki/Pentagon">Pentagons</a>.</p> <p class="nobility hexagon">Next above these come the Nobility, of whom there are several degrees, beginning at Six-Sided Figures, or <a href="http://en.wikipedia.org/wiki/Hexagon">Hexagons</a>, and from thence rising in the number of their sides till they receive the honourable title of <a href="http://en.wikipedia.org/wiki/Polygon">Polygonal</a>, or many-Sided. Finally when the number of the sides becomes so numerous, and the sides themselves so small, that the figure cannot be distinguished from a <a href="http://en.wikipedia.org/wiki/Circle">circle</a>, he is included in the Circular or Priestly order; and this is the highest class of all.</p> <p><span class="pull-quote">It is a Law of Nature <span class="drop">with us</span> that a male child shall have <strong>one more side</strong> than his father</span>, so that each generation shall rise (as a rule) one step in the scale of development and nobility. Thus the son of a Square is a Pentagon; the son of a Pentagon, a Hexagon; and so on.</p> </div> </body> </html>
