Post方法,返回text,后台获得Data
View
$.ajax({
type: "POST",
dataType: "text",//返回类型为文本
url:"/Order/AjaxGetCoupon?ids="+id, data: { ConponCode: code, TotalPrice: totalPrice },
success: function (data) {
if (data == "False") {
ShowFailTip('服务器繁忙,请稍候再试!');
return;
}
else if (data == "No") {
ShowFailTip('您输入的优惠券不存在或已过期!');
return;
} else if (data == "Used") {
ShowFailTip('您输入的优惠券已使用!');
return;
} else if (data == "Limit") {
ShowFailTip('您输入的优惠券不满足最低消费金额!');
return;
} else {
$("#couponPriceId").text("¥" + data.split("|")[0]);
$("#payPriceId").text("¥" + data.split("|")[1]);
}
}
});
Code
[HttpPost]
public ActionResult AjaxGetCoupon(FormCollection Fm,int ids)
{//ids为url中的参数或后台获得URL后的参数 Request.QueryString["ids"]
if (string.IsNullOrWhiteSpace(Fm["ConponCode"]))
{
return base.Content("False");
}
string couponCode = Fm["ConponCode"];
decimal num = Globals.SafeDecimal(Fm["TotalPrice"], (decimal) 0M);
BLL.CouponInfo info = new BLL.CouponInfo();
Model.CouponInfo couponInfo = info.GetCouponInfo(couponCode, false);
if (couponInfo != null)
{
if (couponInfo.Status == )
{
return base.Content("Used");
}
if (couponInfo.LimitPrice >= num)
{
return base.Content("Limit");
}
ShoppingCartInfo cartInfo = new ShoppingCartHelper(base.currentUser.UserID).GetShoppingCart4Selected();
switch (info.GetUseStatus(cartInfo, couponInfo))
{
case :
return base.Content("No"); case :
{
string str2 = (num - couponInfo.CouponPrice).ToString("F");
return base.Content(couponInfo.CouponPrice.ToString("F") + "|" + str2);
}
case :
return base.Content("Used"); case :
return base.Content("Limit"); case :
return base.Content("CategoryLimit"); case :
return base.Content("ProductLimit"); case :
return base.Content("SKULimit"); case :
return base.Content("CategoryNo"); case :
return base.Content("ProductNo"); case :
return base.Content("SKUNo");
}
}
return base.Content("No");
}
若需要返回json则将 $.ajax 中 dataType: "json"
后台:public JsonResult AjaxGetCoupon(FormCollection Fm,int ids){
return Json(new { errCode =0,message= "非常抱歉" });
}
页面传参
location.href = " Order/SubmitOrder?sku=" + sku + "&g=" + groupbuyid;
public ActionResult SubmitOrder(string sku, int count = 1, int c = 0, int g = 0, string viewName = "SubmitOrder")
{
ShoppingCartInfo cartInfo = new ShoppingCartInfo();
return base.View(viewName, cartInfo);
}
