jscript function to validate a text field	1/2/2009 2:20:56 PM

E enfoque_traza author Hi, I want to use the function NIF (see code bellow) to validate a text field when adding or editing a record. The field name is 'DN+LETRA'. I've tried the following code in the "after record added" table events and I've copied the NIF function inside the include/jsfunctions.js file. It doesn't work: I cannot add any new record. Any suggestion? Thanks, ========================= dim DLE DLE=dict("DNI+LETRA") if nif(DLE) then AfterAdd = True else Response.Write "Error" AfterAdd = False end if ========================= function nif(dni) { if (dni.length!=9) return false; numero = dni.substr(0,dni.length-1); let = dni.substr(dni.length-1,1); numero = numero % 23; letra='TRWAGMYFPDXBNJZSQVHLCKET'; letra=letra.substring(numero,numero+1); if (letra!=let) return false; else return true; }

	Hi, to add JavaScript code proceed to the Visual Editor tab, switch to HTML mode and add your code at the end of the page. Here is a sample: <script> function nif(dni) { if (dni.length!=9) return false; numero = dni.substr(0,dni.length-1); let = dni.substr(dni.length-1,1); numero = numero % 23; letra='TRWAGMYFPDXBNJZSQVHLCKET'; letra=letra.substring(numero,numero+1); if (letra!=let) return false; else return true; } document.forms.editform.value_DLE.onchange=function() { if (!nif(document.forms.editform.value_DLE.value)) alert('Error'); } </script>
