Trying to get a number field (Age) to only allow numeric entries.  Possible?  In a basic HTML5 form it would just be <input type="number">.  Am I missing something?

In a perfect world, a pop up message when alpha characters entered would also e nice.


As far as I know you can't define "number" form element on a datapage, I suppose that your field is set to text form element even if your datatype is number in a table. However, you will not be able to submit characters, an error message should appear once you hit "Submit"

I use script from this  post on my datapage. This script allows entering numbers only in a field.

Another option - you can create an html form and submit data to caspio: http://howto.caspio.com/tech-tips-and-articles/advanced-customizations/how-to-convert-existing-html-forms-to-work-with-caspio/

Mylene.  This is working with one exception.  

Works great but wont work on two other text fields setup the same way. The only thing different is that the two fields where it doesn't work are fields that Show/Hide based on a Rule. Wondering if that Rule status is preventing the field name to be recognized by the script?


function isNumberKey(evt){
var charCode = (evt.which) ? evt.which : event.keyCode
if (charCode > 31 && (charCode < 48 || charCode > 57))
return false;
return true;
document.getElementById('InsertDTN_time').onkeypress =isNumberKey;
