Java Script Function

try here they have some input masks that you can download for free http://www.webresourcesdepot.com/javascript-input-masks/

Hi,

try this:

function format()
{
   var num = document.getElementById('phone').value;
   bluh
   bluh
   bluh
}

<input name="phone" type="text" id="phone" onchange="format();" /></form>

Select allOpen in new window

that will trigger your function, everytime the inputfield looses its focus. If you want to trigger it everytime the value changes, use the onkeyup-event instead of onchange.

Hi Dr_Pitter,

  I have several text fields that need to apply this mask.  From what you described, that means I'll need to build one function for each text field.  Is there a better way?

Thank you!

hi cuconsortium,

You can set the formatting to all inputs with the same classname after loading the page by using the window.onload event.

Given you have these inputs where to set the formatting:

<input name="phone" type="text" id="phone" class="num_format" />
<input name="phone1" type="text" id="phone1" class="num_format" />
<input name="phone2" type="text" id="phone2" class="num_format" />
<input name="phone3" type="text" id="phone3" class="num_format" />

Create these javascript functions:

<script type="text/javascript">
function  format(num) {
    bluh
    bluh
    bluh
}
function setFormat()  {
      var inputs = document.getElementsByClassName('num_format');

      for( var x=0; x<inputs.length; x++ ) {
           //set the formatting
            inputs[x].onchange = function() {
                  var num = this.value;
                 
                  format(num);
            }
       }
}

window.onload = setFormat;
</script>

With that, all settings of onchange event to inputs with "num_format" class will be done after the loading of page.

Hope that helps... Have a good day... :)
