效果：成型日期-齡期=要求試驗日期！

事件：

當(dāng)改變成型日期文本框后觸發(fā)事件！
當(dāng)改變齡期文本框后觸發(fā)事件！
代碼：
（說明：成型日期ID: tbcxrq     齡期ID: tblq      要求試驗日期ID: tbyqsyrq）

復(fù)制代碼 代碼如下:

<script type="text/javascript">

        $(function() {
            $("#<%=tbcxrq.ClientID %>").change(function() { CaclDate(); });
            $("#<%=tblq.ClientID %>").change(function() { CaclDate(); });
            //根據(jù)齡期計算試驗時間
            function CaclDate() {

if ($("#<%=tblq.ClientID %>").val() == "" || $("#<%=tbcxrq.ClientID %>").val() == "") {
                    $("#<%=tbyqsyrq.ClientID %>").val("");
                }
                else {
                    var MoldingDate = $("#<%=tbcxrq.ClientID %>").val();
                    MoldingDate = MoldingDate.replace("-", "/")
                    var d = new Date(MoldingDate);
                    var AgeDate = $("#<%=tblq.ClientID %>").val();
                    d.setDate(d.getDate() + parseInt(AgeDate));
                    var month = d.getMonth() + 1;
                    if (parseInt(month) < 10)
                        month = "0" + month;
                    var day = d.getDate();
                    if (parseInt(day) < 10)
                        day = "0" + day;

                    var date = (d.getFullYear()) + "-" + month + "-" + day;
                    $("#<%=tbyqsyrq.ClientID %>").val(date);
                }
            }
        });
    </script>
