我有几个BIOS,看起来都是这样的:

<p>
  Lorem ipsum dolor sit amet, consectetur adipiscing elit. Quisque tincidunt auctor purus, ut cursus quam fringilla id. Suspendisse a libero id mauris faucibus convallis at ut lacus.
  <br><br> Lorem ipsum dolor sit amet, consectetur adipiscing elit. Quisque tincidunt auctor purus, ut cursus quam fringilla id. Suspendisse a libero id mauris faucibus convallis at ut lacus.
  <br><br> Lorem ipsum dolor sit amet, consectetur adipiscing elit. Quisque tincidunt auctor purus, ut cursus quam fringilla id. Suspendisse a libero id mauris faucibus convallis at ut lacus.
  <br><br> Lorem ipsum dolor sit amet, consectetur adipiscing elit. Quisque tincidunt auctor purus, ut cursus quam fringilla id. Suspendisse a libero id mauris faucibus convallis at ut lacus.
  <br><br> Lorem ipsum dolor sit amet, consectetur adipiscing elit. Quisque tincidunt auctor purus, ut cursus quam fringilla id. Suspendisse a libero id mauris faucibus convallis at ut lacus.
  <br><br> Lorem ipsum dolor sit amet, consectetur adipiscing elit. Quisque tincidunt auctor purus, ut cursus quam fringilla id. Suspendisse a libero id mauris faucibus convallis at ut lacus.
</p>

不是最漂亮的文本块,但它们是由系统自动生成的。我需要遍历每个<p>,并获取第一组break标记之后的所有内容,然后将其 Package 在类似<div>的东西中。
最终结果将是:

<p>
  Lorem ipsum dolor sit amet, consectetur adipiscing elit. Quisque tincidunt auctor purus, ut cursus quam fringilla id. Suspendisse a libero id mauris faucibus convallis at ut lacus.</p>
<div class="theRest">
  Lorem ipsum dolor sit amet, consectetur adipiscing elit. Quisque tincidunt auctor purus, ut cursus quam fringilla id. Suspendisse a libero id mauris faucibus convallis at ut lacus.
  <br><br> Lorem ipsum dolor sit amet, consectetur adipiscing elit. Quisque tincidunt auctor purus, ut cursus quam fringilla id. Suspendisse a libero id mauris faucibus convallis at ut lacus.
  <br><br> Lorem ipsum dolor sit amet, consectetur adipiscing elit. Quisque tincidunt auctor purus, ut cursus quam fringilla id. Suspendisse a libero id mauris faucibus convallis at ut lacus.
  <br><br> Lorem ipsum dolor sit amet, consectetur adipiscing elit. Quisque tincidunt auctor purus, ut cursus quam fringilla id. Suspendisse a libero id mauris faucibus convallis at ut lacus.
  <br><br> Lorem ipsum dolor sit amet, consectetur adipiscing elit. Quisque tincidunt auctor purus, ut cursus quam fringilla id. Suspendisse a libero id mauris faucibus convallis at ut lacus.
</div>
</p>

试试这个(灵感来自@Dave回答):

$("p").each(function(){

    // Add a div after the second <br /> (in the current <p>)
    $("br:eq(1)", this).after('<div class="theRest"> </ div>');

    // Split each "child" in an array
    $(this).contents().filter(function(index, elem){

        // Keep only children after the <div />
        return index > 3;

    // Remove and put them into the <div />
    }).detach().appendTo($(".theRest", this));
});

试试这个:

$('p').each(function() {
    $(this).contents(':gt(2)').wrap('<div class="theRest"></div>');
});

但这不是一个足够好的解决方案。
为了防止你的其他p元素被 Package ,你应该从任何父元素中找到如下:

$('.father').find('p').each(function() {
    $(this).contents(':gt(2)').wrap('<div class="theRest"></div>');
});

试试这个:

$($("p").contents().get(2)).after('<div class="theRest"></div>');
$("p").contents().filter(function(index, element) {
    return index > 3;
}).detach().appendTo(".theRest");

即使从服务器返回的格式是坏的,从我的标准,因为它复杂的事情为给定的目的。不过,有了一些技巧,还是有办法做到的。
说明:选择所有节点,丢弃第一个节点,因为它恰好是文本节点,然后使用jquery wrapAll方法获取该节点之后的所有内容并将其 Package 在新的div中。

Demo:http://jsfiddle.net/qe3bm92e/3/

var txt = $('.txt').contents();
txt.splice(0,1);
txt.wrapAll($("<div>").addClass('red'));

您可以用'p'替换'.txt',但这不是一个很好的实践,原因非常明显。
