请看下面的代码。它在我身边起作用。

function validatePassword(){
  var password= document.forms["PestControl"]["password"];
  var confirmpassword= document.forms["PestControl"]["confirmpassword"];           
  var Exist   =   false;
  if((password.value === '') && (confirmpassword.value==='')) {
    alert('no input');
    Exist   =   false;
  } 
  else if(password.value != confirmpassword.value) {
   alert('wrong password');
   Exist   =   false;
  } 
  else {
    alert('correct');
    Exist   =   true;
  }
  async:false;
  return Exist;

}

Answer 2

function validatePassword(){
var password= document.getElementById("your pass id").value;
var confirmpassword= document.getElementById("confirm_password").value;                   
 var Exist   =   false;
if((password === '') && (confirmpassword==='')) {
  alert();
  Exist   =   false;
} 
else if(password != confirmpassword) {
  Exist   =   false;
} 
else {
  Exist   =   true;
}
}
