Question

input中id怎么变成活的，并让jquery获取volist循环出的id（这是购物车加减功能）

<volist name="products" id="hostlist">
<div class="t">数量：</div>
<div class="c buynum">
<i style="cursor: pointer;" class="numadjust dec" onclick="plus_minus({pigcms:$hostlist.id}, -1,{pigcms:$hostlist.price})"></i>
<input id="buy_num" name="goods[num]" type="text" value="1">
<i style="cursor: pointer;" class="numadjust add" onclick="plus_minus({pigcms:$hostlist.id}, 1,{pigcms:$hostlist.price})"></i>
<span class="stock"><span id="stock">{pigcms:$hostlist.num}</span></span>
</div>
</volist>

Answer 1

id="id_{$id}"

可以这样~~

追问

var num = parseInt($('#buy_num').val());
input中id变化了，jquery中怎么传过去呀，本人菜鸟，在做多个商品加减按钮
