JSP向Servlet传递数组参数

今天需要做一个多选删除功能，需要从JSP中获取已勾选的多选框的值，传递到Servlet中进行删除操作。

<input type="checkbox" name="checkProduct" value="${product.pid}"><input type="checkbox" name="checkProduct" value="${product.pid}"><input type="checkbox" name="checkProduct" value="${product.pid}"><input type="checkbox" name="checkProduct" value="${product.pid}"><button type="button" id="delete" name="delete" value="删除" class="button_add" onclick="delCheckProduct()">删除</button>


<script type="text/javascript"> function delCheckProduct() {    //获取多选框的选中状态    product = document.getElementsByName("checkProduct");checkProduct = [];for(k in product){    if (product[k].checked){checkProduct.push(product[k].value);}}//alert(checkProduct);//删除var isDel = confirm("确认删除吗？");if (isDel){    //将checkProduct数组当做参数传递到servlet    window.location.href = "${pageContext.request.contextPath}/adminDelProductByChecked?checkProduct="+checkProduct;}            }</script>

在Servlet中接收传递过来的值：
String checkProduct = request.getParameter("checkProduct");//        System.out.println(checkProduct);        String uid[] = checkProduct.split(",");        AdminDelProductByCheckedService service = new AdminDelProductByCheckedService();        try {            service.delProductByChecked(uid);        } catch (SQLException e) {            e.printStackTrace();        }        for (int i = 0; i < uid.length; i++){            System.out.println(uid[i]);        }    }
