Allow only number entry

Recommended Posts

Add HTML block at the end of your element list or in the footer of your page, click on Source and use the code below


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

Replace InsertRecordPhone with actual field ID that you want to only allow numbers

Hello @Armopankaj,

You may refer to this post https://forums.caspio.com/topic/4377-js-guide-caspio-form-elements/

If you have a Submission form and let`s say the field name is Number, then please use document.getElementById('InsertRecordNumber').

Hope this helps.  Feel free to update this thread if you need any help with the script.
