Apply script functions to multiple fields?

[roattw]

I have a script forcing numeric characters only in a couple fields (thanks May Music).  

<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('InsertRecordFIELD1').onkeypress =isNumberKey;
</script>

 

I had several fields like this so I cheated and created one script for each FIELDNAME (I know, I know, Im still learning  :^).  How could I combine all fields into that one script above?  I tried this but it didnt work:

document.getElementById('InsertRecordFIELD1','InsertRecordFIELD2','InsertRecordFIELD3')

Just write two additional lines which will call function for each field:

document.getElementById('InsertRecordFIELD1').onkeypress =isNumberKey; 

document.getElementById('InsertRecordFIELD2').onkeypress =isNumberKey;

document.getElementById('InsertRecordFIELD3').onkeypress =isNumberKey;
