如何在JavaScript中验证出生日期为正确的日期格式 [英] How to validate a date of birth as correct date format in JavaScript

问题描述

我正在寻找帮助撰写IF声明，以确认输入的出生日期是正确的格式，例如dd / mm / yyyy但由于我不熟悉JavaScript，我不确定如何做到这一点。



我有一个函数用于何时从文本中插入数据下面显示的方框，但是我需要在此函数中使用if语句来确认DOB是否有效。



任何帮助将不胜感激。

I am looking for help in writing an IF statement to validate that an inputted date of birth is in the correct format e.g. dd/mm/yyyy but as i am new to JavaScript i am unsure on how to do this.

I have a function for when the data is inserted from the text boxes shown below but i need to have the if statement within this function to confirm DOB is valid.

any help would be greatly appreciated.

function butUpdate() {

        var vUserid = escape($("#dEditlogin").val());
        var vStaffid = escape($("#dEditstaff").val());
        var vSurname = escape($("#dEditsurname").val());
        var vFirstname = escape($("#dEditfirstn").val());
        var vMiddlename = escape($("#dEditmiddle").val());
        var vDateofbirth = escape($("#dEditdob").val());
        var vJobtitle = escape($("#dEditjob").val());
        var vDepartment = escape($("#dEditdept").val());
        var vSite = escape($("#dEditsite").val());

        var link = 'EditUser.aspx?userid=' + vUserid + '&staffid=' + vStaffid + '&surname=' + vSurname + '&firstname=' + vFirstname + '&middlename=' + vMiddlename + '&dob=' + vDateofbirth + '&jobtitle=' + vJobtitle + '&department=' + vDepartment + '&site=' + vSite;

        $.get(link, function (data) {
            $("#dMsg").empty().append(data);
            $("#ContentPlaceHolder1_dUpdatemsg").css("left", "200px");
            $("#ContentPlaceHolder1_dUpdatemsg").css("display", "block");
            });


    }
