title: Not allow more than 5 digits after decimal. in on javascript "OnKeyUp"?
body: <p>I have a javascript code for textbox that will put commas on in digits like (11,23,233)</p>
  
  <pre><code> mTextbox.Attributes.Add("OnKeyUp", "javascript:this.value=Comma(this.value);")
  
  function Comma(Num) {
  
          Num += '';
          Num = Num.replace(',', ''); Num = Num.replace(',', ''); Num = Num.replace(',', '');
          Num = Num.replace(',', ''); Num = Num.replace(',', ''); Num = Num.replace(',', '');
          x = Num.split('.');
          x1 = x[0];
          x2 = x.length &gt; 1 ? '.' + x[1] : '';
          var rgx = /(\d+)(\d{3})/;
          while (rgx.test(x1))
              x1 = x1.replace(rgx, '$1' + ',' + '$2');
          return x1 + x2;
      } 
  </code></pre>
  
  <p>Now same here I need to restrict user to enter not morethan 5 digits after decimal (ex: </p>
  
  <pre><code>Allow: 12,23,221.34323
  
  Not Allow: 12,23,232.232423
  </code></pre>
  
  <p>I can change above javascript to work that?</p>
