控制器下的代码
[HttpPost] public ActionResult Index6() { string zh ="XXXXXXX";//短信接口账户 string mm = "123456";//账户密码 int sms_type = 42; //通道编号 string dealType = Request["dealType"];//电话号码 string uid = Request["uid"];//用户ID string code = Request["code"];//随机数
//内容 string nr = "您好用户：" + uid + ",你的验证码为：" + code + "请尽快输入!";
//短信接口通道地址如： string url = "http://www.6610086.net/jk.aspx?zh=" + zh + "8&mm=" + mm + "&hm=" + dealType + "&nr=" + nr + "&sms_type=" + sms_type; Response.Redirect(url); // Response.Write("<script>$.ajax({type: ‘POST‘, dataType: ‘text‘, url: " + url + ",data:null,error: function (XMLHttpRequest, textStatus, errorThrown) { },success: function (msg) { }});</script>"); //Response.Write("<script>$.ajax([type:‘POST‘,dataType:‘text‘,]);</script>"); return View(); }
jquery 实现 点击按钮后倒计时效果，多用于实现发送手机验证码
