我需要抓住以下内容：
alt =＆＃34; 2806＆＃34;
的2806部分值的35分=＆＃34; 35＆＃34;标题=＆＃34;数量＆＃34;
alt =＆＃34; 1120＆＃34;
的1120部分值的104部分=＆＃34; 104＆＃34;标题=＆＃34;数量＆＃34;
alt =＆＃34; 2922＆＃34;
的2922部分值的3部分=＆＃34; 3＆＃34;标题=＆＃34;数量＆＃34;
1666部分的alt =＆＃34; 1666＆＃34;
22的值=＆＃34; 22＆＃34;标题=＆＃34;数量＆＃34;
我看过这个页面：
Javascript: How to loop through ALL DOM elements on a page?
和这个页面：
http://www.w3schools.com/js/js_htmldom_nodelist.asp
而且我有点过头了。
我需要的是一些javascript代码，它将导致...包含以下内容的变量：
<input type="hidden" name="prodnum" value="2806" />
<input type="hidden" name="prodqty" value="35" />
<input type="hidden" name="prodnum" value="1120" />
<input type="hidden" name="prodqty" value="104" />
<input type="hidden" name="prodnum" value="2922" />
<input type="hidden" name="prodqty" value="3" />
<input type="hidden" name="prodnum" value="1666" />
<input type="hidden" name="prodqty" value="22" />
我会继续为此而努力，看看我是否能够自己解决这个问题，但这种可能性并不适合我。
感谢您提供的任何帮助！

你可以使用三维javascript对象来做到这一点：
var stObj = {};
$('#mybutt').click(function(){
var cnt = 0;
$('.shop_table tbody tr:not(:last-child)').each(function(){
//alert( this.className );
cnt++;
stObj[cnt] = {};
$this = $(this);
var thImg = $this.find('.product-thumbnail a img').attr('alt');
//alert(thImg);
var prQty = $this.find('.product-quantity div input').val();
//alert(prQty);
stObj[cnt]['thImg'] = thImg;
stObj[cnt]['prQty'] = prQty;
});
alert( JSON.stringify(stObj) );
});
注意：
（1）对象stObj全局定义（即外部 - 上面 - 使用它的函数）
（2）jQuery选择器tr:not(:last-child)阻止尝试在最后一行表中找到alt和value
（3）在jsFiddle中，#tst div立即被代码隐藏。如果可见，它只显示代码被破坏而无需按任何按钮。
