Change this in formValidate() 在formValidate（）中更改此
document.myForm.Name.value == "" to document.myForm.dob.value == "" document.myForm.Name.value == "" to document.myForm.dob.value == ""
document.myForm.EMail.value == "" to document.myForm.email.value == ""
Do not use 不使用
document.write("<b>" + day + "/" + month + "/" + year + "</b>");
It will replace the whole contents of your body 它将取代你身体的全部内容

First of all,in your formValidate(), 首先，在你的formValidate(),
First if condition is incorrect.Your form does not have a "name" element, it should either be "dob" or "age" or "value". 首先，如果条件不正确。您的表单没有“name”元素，它应该是“dob”或“age”或“value”。
Secondly , in the second if instead of this if( document.myForm.EMail.value == "" ) , it should be if( document.myForm.email.value == "" ) . 其次 ，在第二个if而不是if( document.myForm.EMail.value == "" ) ，它应该是if( document.myForm.email.value == "" ) 。
