Hi,
How do I validate a form text input only if it has any value in it? I am using ValidNumeric and ValidDate for some form text boxes. But I want to validate them only if they have any value in it. I don’t want to validate a textbox if it is empty. Thanks.
Just create a custom validation rule as
docs.dhtmlx.com/doku.php?id=dhtm … _extension
dhtmlxValidation.isValidNumericEmpty=function(a){
if (a=="") return true;
return this.isValidNumeric(a);
}
//after that ValidNumericEmpty rule can be used
That was really helpful. Thanks a ton!
