$(".calBtn").click(function () {

    if($(this).children('a').hasClass('btn_sty') && $(".son_check + label.mark").length > 0){
        var sp_ids = ""
        $(".son_check + label.mark").each(function () {
            sp_ids += ($(this).attr("for")+"_")
        })
        $.post('/user/provideOrders',{"sp_ids":sp_ids},function (result) {
            if(result.error == 0){
                zlalert.alertSuccess("生成订单成功，接下来为你跳转到订单页面",function () {
                    window.location.href="/user/showOrder?oid="+result.oid
                })
            }
        })
    }
})

<button type="button" class="btn btn-success calBtn">去支付</button>

你期待的结果是什么？实际看到的错误信息又是什么？

如何实现这个按钮，让它正常跳转。实际上点击没有任何反应。
