i am getting error message but not clearing the fields after entering in the text box

Question

the below is the script i have written, by using below code i am getting error message properly but, if i enter the field the error message still be displaying any idea how to clear the error message.

var flag=0
     function otpValidate()
     (
         otp=oneTimePass.onetimepass.value
         if(otp=="")
         (
             document.getElementById('error0').innerHTML="Enter one time password"
             flag=1;
         )else if(otp.length != 6)
         (
             document.getElementById('error0').innerHTML="PIN must be 6 digits"
             flag=1
         )
     )   
     function check(form)
 (
     flag==0
     otpValidate()
     if(flag=1)
         return false

     else
         return true
 )

what line is erroring out? is oneTimePass an object with an attribute of .onetimepass that is not null? Obviously that would cause an error if so — Joseph Duty, Sep 28 '15 at 14:28
replace `function otpValidate() (... )` to `function otpValidate() {... }` — Sherali Turdiyev, Sep 28 '15 at 14:28
learn the difference in { vs ( - it seems to be popping up everywhere — Joseph Duty, Sep 28 '15 at 14:34

You have many errors.

if(flag=1) is not a condition but an allocation. Write if(flag==1) instead.

Replace function otpValidate() (... ) to function otpValidate() {... }.

It's the same for if statement. Replace if() (...) by if() {...}

Note : At the end line you should add ; in javascript

Code without mistake :

var flag = 0;
function otpValidate() {
     otp = oneTimePass.onetimepass.value;
     if(otp == "") {
         document.getElementById('error0').innerHTML = "Enter one time password";
         flag = 1;
     } else if(otp.length != 6) { 
         document.getElementById('error0').innerHTML = "PIN must be 6 digits";
         flag = 1;
     }
 }  
 function check(form) {
     flag = 0;
     otpValidate();
     if (flag == 1)
         return false;
     else
         return true;
 }
