新手问下按键功能怎么实现

[yoonayao]

jsp用的template
<button class="btn-small pull-right btn-primary relieve-btn btnpadding padding4" onclick>{{if v.status==1}}立即使用{{else}}立即领取{{/if}}</button>

controller
/**
* 优惠券微网站领取
* @return
*/
@RequestMapping("/couponSendWebReceive")
@ResponseBody
public Result couponSendWebReceive(HttpServletRequest request,QueryCouponSendParam receiveParam){
Result result = Result.successResult();
UserDTO user=(UserDTO)request.getSession().getAttribute(Constants.SESSION_LOGIN);
receiveParam.setUserName(user.getId());
try {
couponSendManagerSerivce.couponSendWebReceive(receiveParam);
LogUtil.insertLog(logtextService, 2, receiveParam.getCustomerId()+"会员领取优惠券", user.getName());
} catch (Exception e) {
result = Result.errorResult("操作失败");
}
return result;
}
新手问下按键功能怎么实现,这是我写的
$(".padding4").click(function() {
$.ajax({
url:ctxAdmin+"/couponSend/couponSendWebReceive",
type:"post",
success:function(data){
if(data.status==0){
data.status=1,
$(".padding4").value="立即使用";
}else{
console.log("111");
}
}
});
});

按键功能就是button啊，给个方法就好了

[yoonayao]

方法可以了，if判断不行

jsp 用el表达式，或者写 js判断
