javascript - 如何基于Microsoft CRM 2011中的出生日期来计算年和月的年龄

我知道这是使用javascript库完成的。当前，我为CRM 2011找到的唯一示例仅涉及使用以下代码计算年龄（以年为单位）：

function CalcAge()
{
var now = new Date(); //Todays Date
var birthday = Xrm.Page.getAttribute("birthdate").getValue(); //Get the Date of Birth value
var diff = now.getMonth() - birthday.getMonth();  //Check to see if Birthday  has already passed

if (diff > -1) //If Birthday has already occurred
{
    var bd1 = now.getFullYear() - birthday.getFullYear();

    //set the age attribute
    Xrm.Page.getAttribute("frc_age").setValue(bd1.toString());
}
else //If Birthday has not already occurred
{
    var bd2 = now.getFullYear() - birthday.getFullYear() - 1;
    Xrm.Page.getAttribute("frc_age").setValue(bd2.toString());
}
}

我需要帮助来实现一个类似的功能，该功能也占了几个月的时间。

最佳答案

如果DOB的格式为“ MM / dd / yyyy”，则可以尝试以下代码。您也可以相应地将其更改为其他格式。

var now = new Date(); //Todays Date
var birthday = Xrm.Page.getAttribute("birthdate").getValue();
birthday=birthday.split("/");

var dobMonth= birthday[0];
var dobDay= birthday[1];
var dobYear= birthday[2];

var nowDay= now.getDate();
var nowMonth = now.getMonth() + 1;  //jan = 0 so month + 1
var nowYear= now.getFullYear();

var ageyear = nowYear - dobYear;
var agemonth = nowMonth - dobMonth;
var ageday = nowDay- dobDay;
if (agemonth <= 0) {
       ageyear--;
       agemonth = (12 + agemonth);
        }
if (nowDay < dobDay) {
      agemonth--;
      ageday = 30 + ageday;
      }
var val = ageyear + "-" + agemonth + "-" + ageday;
return val;

您还可以使用以下一些功能：
