我通过将其添加到函数resetForm（）

中解决了这个问题 
function resetForm(){
document.getElementById('errorFirstNameMissing').style.display='none';
document.getElementById('errorFirstNameInValid').style.display='none';
document.getElementById('errorLastNameMissing').style.display='none';
document.getElementById('errorLastNameInValid').style.display='none';
document.getElementById('errorMissingCategory').style.display='none';
document.getElementById('errorMissingGender').style.display='none';
document.getElementById('errorMissingDOB').style.display='none';
document.getElementById('errorDateInvalid').style.display='none';
document.getElementById('errorMissingAddress').style.display='none';
document.getElementById('errorMissingState').style.display='none';
document.getElementById('errorMissingCity').style.display='none';
document.getElementById('errorMissingPinCode').style.display='none';
document.getElementById('errorPinCodeInvalid').style.display='none';
document.getElementById('errorMissingEmail').style.display='none';
document.getElementById('errorEmailInvalid').style.display='none';
document.getElementById('errorStdCodeInvalid').style.display='none';
document.getElementById('errorPhoneNoInvalid').style.display='none';
document.getElementById('errorMissingMobileNo').style.display='none';

}

 function resetForm(){
 document.getElementById('errorFirstNameMissing').innerHTML="";
 document.getElementById('errorFirstNameInValid').innerHTML="";
 document.getElementById('errorLastNameMissing').innerHTML="";
 document.getElementById('errorLastNameInValid').innerHTML="";
 document.getElementById('errorMissingCategory').innerHTML="";
 document.getElementById('errorMissingGender').innerHTML=""
 document.getElementById('errorMissingDOB').innerHTML="";
 document.getElementById('errorDateInvalid').innerHTML="";
 document.getElementById('errorMissingAddress').innerHTML="";
 document.getElementById('errorMissingState').innerHTML="";
 document.getElementById('errorMissingCity').innerHTML="";
 document.getElementById('errorMissingPinCode').innerHTML="";
 document.getElementById('errorPinCodeInvalid').innerHTML="";
 document.getElementById('errorMissingEmail').innerHTML="";
 document.getElementById('errorEmailInvalid').innerHTML="";
 document.getElementById('errorStdCodeInvalid').innerHTML=""; 
 document.getElementById('errorPhoneNoInvalid').innerHTML="";
 document.getElementById('errorMissingMobileNo').innerHTML="";
