本文介绍了一个基于JSP的满减功能实现方案，通过Java后台处理数据，并使用JavaScript进行前端交互，实现了满减条件的动态添加与删除。

1:jsp页面

				<div class="control-group form-group all_activity">
				<c:choose>
				   <c:when test="${fullCutList !=null  && fullCutList.size() >0}">
				      <c:forEach items="${fullCutList }" var="fullCut" begin="0" varStatus="status">
				      <c:set var="num" value="${status.count-1}"></c:set>
					      <div class="activity_class" >
							<label for="fullMoney" class="col-md-2 control-label" style="width: 50px">满</label>
	 						<div class="col-md-1">
								<input type="text" id="fullCutList[${num}].fullMoney" name="fullCutList[${num}].fullMoney"value="${fullCut.fullMoney }" class="form-control full_money" style="width: 150%" />
							</div>
							<label for="subtractMoney" class="col-md-2 control-label" style="width: 50px">减</label>
							<div class="col-md-1">
								<input type="text" id="fullCutList[${num}].subtractMoney" name="fullCutList[${num}].subtractMoney"value="${fullCut.subtractMoney }" class="form-control subtract_money" style="width: 150%" />
							</div>
						   </div>
					    </c:forEach>
				   </c:when>
				   <c:otherwise>
				      <div class="activity_class" style="margin-top:-26px;">
						<label for="fullMoney" class="col-md-2 control-label" style="width: 50px">满</label>
 						<div class="col-md-1">
							<input type="text" id="fullCutList[0].fullMoney" name="fullCutList[0].fullMoney"value="" class="form-control full_money" style="width: 150%" />
						</div>
						<label for="subtractMoney" class="col-md-2 control-label" style="width: 50px">减</label>
						<div class="col-md-1">
							<input type="text" id="fullCutList[0].subtractMoney" name="fullCutList[0].subtractMoney"value="" class="form-control subtract_money" style="width: 150%" />
						</div>
					  </div>
				   </c:otherwise>
				</c:choose>
				</div>
				<div class="activity_add">
				   <span class="title_name add_coupon">添加条件</span>
				   <span class="konck_icon konck_h"></span>
				</div>

下面是js

//点击“加”事件
		$(".activity_add").click(function(e) {
			addFullSubtract();//调用满减优惠动态添加方法
			sort();//排序方法
		});
		//点击“删除”事件
		$('body').on('click', '.dell_all', function() {
			$(this).parent().remove();
			sort();//排序方法
		});
	//满减优惠动态添加方法
	function addFullSubtract() {
		var fullSubtract = '<div class="activity_class">'
				+ '<label for="fullMoney" class="col-md-2 control-label" style="width: 50px">满</label>'
				+ '<div class="col-md-1">'
				+ '<input type="text" value="" class="form-control full_money" style="width: 150%" />'
				+ '</div>'
				+ '<label for="subtractMoney" class="col-md-2 control-label" style="width: 50px">减</label>'
				+ '<div class="col-md-1">'
				+ '<input type="text" value="" class="form-control subtract_money" style="width: 150%" />'
				+ '</div>' + '<div class="dell_all" style="margin-left: 28px;" >'
				+ '<span class="title_name dell_coupon">删除</span>'
				+ '<span class="konck_icon konck_i"></span>' + '</div>'
				+ '</div>';
		$(".all_activity").append(fullSubtract);
	}
	//排序
	var sort = function(){
		$(".activity_class").each(function(i){
			$(this).find(".full_money").attr("name","fullCutList["+i+"].fullMoney");
			$(this).find(".subtract_money").attr("name","fullCutList["+i+"].subtractMoney");
		});
	}

下面是java 后台代码

    /**
     * 保存
     */
    @Override
    public String execute() throws Exception {
        JSONObject result = new JSONObject();
        try {
            List<FullCut> fullCutList = activityFullSubtractParams.getFullCutList();
            Stall stall = stallService.load(activityFullSubtractParams.getStall().getId());

            activityFullSubtract = new ActivityFullSubtract();
            BeanUtils.copyProperties(activityFullSubtractParams, activityFullSubtract);

            if (fullCutList != null && fullCutList.size() > 0) {
                Object fullCutJson = JSON.toJSON(fullCutList);
                activityFullSubtract.setConditions(fullCutJson.toString());// 满多少减多少,以JSON格式保存
            }
            activityFullSubtract.setStall(stall);
           //判断是否合法新建活动
            boolean whether = activityStallService.verificationActivity(activityFullSubtract);
            if(whether){
                result.put("success", "保存失败。该档口在在当前有效日期内已经存在一个活动了");
            }else{
                //保存数据前刷新一下
                String url = orderDomain+"/activity/refreshActivity?stallId="+activityFullSubtract.getStall().getId();
                String data = HttpClientUtil.getCloseableHttpResponse(url);
                System.out.println(data);
                activityFullSubtractService.addActivityFullSubtract(activityFullSubtract);// 保存
                result.put("success", "保存成功");
            }
        } catch (Exception e) {
            e.printStackTrace();
        }
        Struts2Util.renderJson(getResponse(), result.toString());
        return null;
    }
