我需要用微笑替换图像标签{smile:smilename}

   <?php
    $pattern = '<img src="/img/smile/(.*?).gif">';
    $replacement = '{smile:$1}';
    $subject = '<div contenteditable="true" id="message_text">text<img src="/img/smile/smile3.gif"><img src="/img/smile/smile3.gif"><img src="/img/smile/smile3.gif"><img src="/img/smile/smile3.gif"><img src="/img/smile/smile3.gif"><img src="/img/smile/smile3.gif"><img src="/img/smile/smile3.gif"><img src="/img/smile/smile3.gif"><img src="/img/smile/smile3.gif"><img src="/img/smile/smile3.gif"><img src="/img/smile/smile3.gif"><img src="/img/smile/smile3.gif"><img src="/img/smile/smile3.gif"><img src="/img/smile/smile3.gif"><img src="/img/smile/smile3.gif"><img src="/img/smile/smile3.gif"><img src="/img/smile/smile3.gif"><img src="/img/smile/smile3.gif"></div>';
    echo preg_replace($pattern, $replacement, $subject, -1 );
    ?>

我明白了:

<div contenteditable="true" id="message_text">text<{smile:smile3}><{smile:smile3}><{smile:smile3}><{smile:smile3}><{smile:smile3}><{smile:smile3}><{smile:smile3}><{smile:smile3}><{smile:smile3}><{smile:smile3}><{smile:smile3}><{smile:smile3}><{smile:smile3}><{smile:smile3}><{smile:smile3}><{smile:smile3}><{smile:smile3}><{smile:smile3}></div> 

• <{smile:smile3}>

但是我需要

• {smile:smile3}

我有以下代码:

$(this).parent().find(".age").removeClass('active').children("input").prop('checked', false);
$(this).addClass('active').children('input').prop('checked', true); 

这有效,但我想缩小它并做这样的事情:

$(this).parent().find(".age").removeClass('active').children("input").prop('checked', false).find(this).addClass('active').children('input').prop('checked', true); 

或者

$(this).parent().find(".age").removeClass('active').children("input").prop('checked', false).children(this).addClass('active').children('input').prop('checked', true); 

这两个例子不起作用,但希望你能得到这个想法.
