onblur="TotalMoney(); onblur 失去焦点事件  TotalMoney（）调用这个方法

 

function TotalMoney() {

            var TotalMoneyCount = $("#detailq").find('.PurchaseIndent').length;

            for (var i = 0; i < TotalMoneyCount; i++) {

                var id = "detail" + i;

                var TotalMoneyOne = $("#" + id + " input:eq(4)").val();

                var TotalMoneyTwo = $("#" + id + " input:eq(5)").val();

                var TotalMoneytherr = $("#" + id + " input:eq(6)").val();

                console.log(id);

                if (TotalMoneyOne != "" && TotalMoneyTwo != "" && TotalMoneytherr != "") {

                    if (TotalMoneyOne != "") {

                        $("#" + id + " input:eq(7)").val(TotalMoneyOne * TotalMoneyTwo * TotalMoneytherr);

                        //TotalMoneyCout();

                        //console.log(TotalMoneyOne);

                    }

                    else {

                        layer.alert("折扣错误！！！");

                    }

                }

                else {

                    layer.alert("数据不能为空！！！");

                }

            }

        }

 

在购买数量为1，且不打折情况金额计算如下

更改购买数量，折扣后在点击页面刷新所得金额
