基于jQuery的為attr添加id title等效果的實現(xiàn)代碼

更新時間：2011年04月20日 21:13:28 作者：

下面的例子是通過jquery為連接增加title描述的代碼，在當前頁的連接上寫上，你好，現(xiàn)在在試驗連接文字的簡單描述。

核心代碼:

<script language="javascript" type="text/javascript"> 
$(document).ready(function(){ 
//$('div.chapter a').attr({'rel':'external'}); 
$('div.chapter a').each(function(index){ 
var $linkthis=$(this) 
$linkthis.attr({ 
'rel':'external', 
'id':'wikilink-'+index, 
'title':'你好，現(xiàn)在在試驗'+$linkthis.text() 
}); 
}); 
$('#wikilink-1').css('fontSize',33); 
}); 
</script>

復制代碼代碼如下:

<p class="square">Our Professional Men and Gentlemen are Squares (to which class I myself belong) and Five-Sided Figures or <a >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 >Hexagons</a>, and from thence rising in the number of their sides till they receive the honourable title of <a >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 >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>
