jQuery查找和插入(jQuery替换)

Question

<div class="twtr-tweet-text">
    <p>lorem ipsum <em>date 19th nov</em></p>
</div>
<div class="twtr-tweet-text">
    <p>lorem ipsum <em>date 18th nov</em></p>
</div>
<div class="twtr-tweet-text">
    <p>lorem ipsum <em>date 17th nov</em></p>
</div>

如何将此块转换为下面的代码.请记住,多个块包含相同的类名等.

<div class="twtr-tweet-text">
    <p><img src="speech_left.jpg" />lorem ipsum <img src="speech_right.jpg" /><em>date 19th nov</em></p>
</div>

所以在<em>开始标记之前和之后的<p>标记之后.twtr-tweet-text{}.

Answer 1

$('.twtr-tweet-text p').prepend('<img src="speech_left.jpg" />');
$('.twtr-tweet-text em').before('<img src="speech_right.jpg" />');
