网上找了一些大家提供的js，不太满意，主要原因是和我拿到手的json格式出入很大，导致改起来很麻烦，于是自己写了点
先上效果图，因为工程原有，带有其他样式插件，不好搬过来，所以这里自己简单画了点样式。
我处理过后的json数据如下：
{
"spec_keys": [
"颜色",
"款式"
],
"spec_kv": {
"颜色": [
"白色",
"黑色",
"橙色"
],
"款式": [
"豪华版",
"标准版"
]
},
"spec_infos": [
{
"spec_info": "@-@黑色@-@标准版@-@",
"sku_id": 111
},
{
"spec_info": "@-@黑色@-@豪华版@-@",
"sku_id": 112
},
{
"spec_info": "@-@白色@-@标准版@-@",
"sku_id": 113
},
{
"spec_info": "@-@白色@-@豪华版@-@",
"sku_id": 114
},
{
"spec_info": "@-@橙色@-@标准版@-@",
"sku_id": 115
}
]
}html代码就比较简单了
<label class="control-label">规格</label>
<div class="spec-div"></div>
<div class="form-control">
<span class="input-group-addon sku-name">随机</span>
<span class="input-group-addon sku-name-lable">X</span>
<span class="input-group-addon sku-count-btn" id="task-count-sub">-</span>
<input type="text" id="taskCount" name="taskCount" value="0">
<span class="input-group-addon sku-count-btn" id="task-count-add">+</span>
</div>js代码如下：
/** ******************************sku********************************************* */
var skuInfos;
var skuKeys;
$(function() {
search_sku();
$(".spec-div").delegate(".spec-uncheck", "click", function() {
if(!$(this).hasClass('spec-invalid')){

});

$(".sku-name").text("随机");
}
});
$("#task-count-sub").on('click', function() {

if (intnum == 0) {
return false;
} else {

}

});

$("#taskCount").val(intnum);
