<div class="modal fade"  id="updateModal" aria-labelledby="updateModalLable" aria-hidden="true" tabindex="-1">

    <script >
         function values(productName,id,productType,productNum,productAmt,createTime){
             $('#productName').val(productName)
             $('#productType').val(productType)
             $('#productNum').val(productNum)
             $('#productAmt').val(productAmt)
             $('#createTime').val(createTime)

         }

    </script>

注意点：

使用标签 th:οnclick="values([[${obj.getProductName()}]],[[${obj.getId()}]],[[${obj.getProductType()}]],[[${obj.getProductNum()}]],[[${obj.getProductAmt()}]],[[${obj.getCreateTime()}]])"

变量参数要使用[[${ }]]这种方式，以免出错。
