使用jquery从段落中删除某些单词

Question

我有一个这样的网页：

<p class="author">By ... on Jan 23, 2012</p>
<p class="content">(some content)</p>

<p class="author">By ... on Jan 23, 2012</p>
<p class="content">(some content)</p>

<p class="author">By ... on Jan 23, 2012</p>
<p class="content">(some content)</p>

...

我想使用jquery从p.author中删除“By”和“on”，结果将是：

<p class="author">... Jan 23, 2012</p>
<p class="content">(some content)</p>
...

谢谢！

Answer 1

$('.author').each(function(){
$(this).text($(this).text().replace(/on|by/g,""))
});

Answer 2

无需额外each：

$("p.author").text(function() {
    return $(this).text().replace(/(By|on)/g, '');
});

Answer 3

$(".author").each( function(){
    var text = this.firstChild.nodeValue;
    this.firstChild.nodeValue = text.replace( /(^By|\bon\b)/g, "" );
});
