no dots in input

hey I need a script for no dots so when some one fills in the input filed they are not able to put in dots.

 

I have found one that removes spaces but not one that removes dots.

 

remove spaces:

<script type="text/javascript">
function nospaces(t){
if(t.value.match(/\s/g)){
alert('Sorry, you are not allowed to enter any spaces');
t.value=t.value.replace(/\s/g,'');
}
}
</script>

 

 

                       

<input class="input mediumfield" name="username" onkeyup="nospaces(this)" type="text" value="" />

Well, no matter what you do you also need to validate on the server page that processes the input.

 

You can handle this in different ways. Personally I don't like scripts that validate on every keystroke. Instead I will validate onblur or on submission of the form. But, to each his own. The following function should work fine.

 

<html>
<head>
<script language="JavaScript" type="text/javascript">
  function hasPeriods(value)
  {
    return value.match(/\./);
  }

  function checkDot(fieldObj)
  {
    if (hasPeriods(fieldObj.value))
    {
        alert('Periods are not allowed.');
        fieldObj.value = fieldObj.value.replace('.', '');
    }
    return;
  }
  </script>
  </head>

  <body>
    <input type="text" name="test_field" onkeyup="checkDot(this);" />
  </body>
</html>
