Client Script alert

[nicolaosoteo]

Hi All,

Hoping for some help with my alert message client script.

I have a requirement to have my customer fill out a field with a minimum and maximum of 6 numbers and no characters.

I have created an onchange client script which appears to work well, however I get a looping alert which needs to be closed for the customer to progress. Can soomebody please tell me what I have done incorrectly in my code?

function onChange(control, oldValue, newValue, isLoading) {   
   if (isLoading ) {   
   return;   
   }   
         var myFieldValue = g_form.getValue('u_mcn_io_number');   
       if (myFieldValue.toString().length < 6) { // or whatever number you want   
               g_form.setValue('u_mcn_io_number','');   
               alert('Please enter 6 or more characters.');   
       }   
   if(oldValue != newValue){   
   var VALIDCHARS = "1234567890";   
   var number   = newValue.trim();   
   var regEx = "^[0-9]*$";   
   var rtn = number.match(regEx);   
   g_form.hideFieldMsg('u_mcn_io_number', true);   
   if (rtn == null) {   
   g_form.showFieldMsg('u_mcn_io_number', number + " is an invalid   number, please re-enter using only characters from " + VALIDCHARS ,'error');   
   return;   
   }   
   }   
}

Here you go, replace first if with this

if (isLoading || newValue === '') {

          return;

  }

Your script will be

function onChange(control, oldValue, newValue, isLoading) {     

if (isLoading || newValue === '') {
           return;
   }



       var myFieldValue = g_form.getValue('u_mcn_io_number');     
       if (myFieldValue.toString().length < 6) { // or whatever number you want     
               g_form.setValue('u_mcn_io_number','');     
               alert('Please enter 6 or more characters.');     
       }     

   if(oldValue != newValue){     

   var VALIDCHARS = "1234567890";     
   var number   = newValue.trim();     
   var regEx = "^[0-9]*$";     
   var rtn = number.match(regEx);     
   g_form.hideFieldMsg('u_mcn_io_number', true);     
   if (rtn == null) {     
   g_form.showFieldMsg('u_mcn_io_number', number + " is an invalid   number, please re-enter using only characters from " + VALIDCHARS ,'error');     
   return;     
   }     
   }     

}
