JavaScript Validation of only "|" (pipe) in the sp

In my textbox I should be able to allow all characters, numbers and special characters except "|" (Pipe) .
The validation should be done using javascript.
I am having the Javascript code for validating all the special characters
But i need to validate only "|"(Pipe) in all special characters

It is very urgent
I need it ASAP.

If you have the code, then just delete all the special symbols except | from it. Hope yoy get what I mean, if not, give us your script

A basic example:

Code:

<input type="text" value="t|e|s|t" onblur="alert(this.value.indexOf('|')>-1?'Pipe should not exist.':'It\'s a valid input');">

the above code is working very fine but
My requirement is , when i enter "|" (pipe) it must not show in the text grid . Please see my code and reply me ASAP .

The below code is my text area

Code:

<textarea rows="4" cols="40" onKeyDown="textCounter(this.form.UNFCCC_Comments,this.form.remLen, 250)" onKeyUp="textCounter(this.form.UNFCCC_Comments,this.form.remLen, 250)"  >

The below code is JS

Code:

function textCounter(field, countfield, maxlimit) {
      //var re = /^[a-zA-Z0-9\n\r\f]*$/; // checking for all the special characters.
      var re = "t|e|s|t" ; 
      if (!re.test(field.value)) 
         {
         field.value = field.value.replace(('|'),"");
         //alert(this.value.indexOf('|')>-1?'Pipe should not exist.':'It\'s a valid input');
         }
      else if (field.value.length > maxlimit) // if too long...trim it!
         field.value = field.value.substring(0, maxlimit);
         
      else    // otherwise, update 'characters left' counter
         countfield.value = maxlimit - field.value.length;
      }

      function trim(str)
      {
         return str.replace(/^\s*|\s*$/g,"");
      }
      function startsWith(str1, str2)
      {
         return (str1.match("^"+str2)==str2);
      }
      function endsWith(str1, str2)
      {
         return (str1.match(str2+"$")==str2)
      }

What's the name of your textarea? Reading the code, you could have simplified it with this:

Code:

<script type="text/javascript">
var ray={
filter:function(el,limit)
   {
   val = el.value.replace(/\|/g,'') ; // Trim trailing white spaces
   el.value=val;
   }
}
</script>
<textarea rows="4" cols="40" onKeyDown="ray.filter(this,250)" onKeyUp="ray.filter(this,250)">
