function aa (){
debugger;
var cardID = IAEnthreeDes("74f9b968","2704122125150801");
var option = IAEnthreeDes("74f9b968","admin");
var price = IAEnthreeDes("74f9b968","110");
var url = "http://192.168.1.34:8080/Interface/GeneralInterfaceHandler.ashx";
var postStr = " do = GetDiscountMoney&CompCode = ' ' & ShopID= ' ' & CardIDorMobile= " + cardID + " & TotalMoney = " +price+ " & MasterAccount = " +option+ " & WeChatID= ''";
$.ajax({
url: url,
data: postStr,
type:'post',
dataType:'json',
success:function(data) {
alert(data);
},
error : function(xhr,erroType,error,msg) {
alert(error);
}
});
}
