请问有没有简洁的办法获得这段代码的所有class

<div>
T<span id='1' class='red'><span id='2' class='bold'>his</span></span> is <span id='3' class='blue'>som</span>e sample text. 
</div>

如何
获得 his 的两个class: red bold
som的一个class: blue
存入数组.

$('span').each(function(){
textArry.push($(this).text());
classArry.push($(this).attr('class'));
})

这样取出再处理,很麻烦.

<div>
T<span id='1' class='red'><span id='2' class='bold'>his</span></span> is <span id='3' class='blue'>som</span>e sample <span>text</span>. 
</div>
<script type="text/javascript" src="http://www.coding123.net/js/jquery.js"></script>
<script>
    $(function () {
        var cls = {};
        $('span').not(':empty').each(function () {
            if (this.firstChild.nodeType == 1) return true;
            kw = this.innerHTML;
            cls[kw] = $(this).parentsUntil('div').add(this).map(function () { return this.className }).get();
        });

        for (kw in cls) alert(kw + '=' + cls[kw]);
    });
</script>

那用下面这个吧

$(function(){
    var data = {} , key;
    $('span').each(function(){
        key = $.trim($(this).text());
        if(!data.hasOwnProperty(key)){
            data[key] = [];
        }
        data[key].push($(this).attr('class'));                
    }); 
    console.log(data);
});
