Hi Dave,
The JavaScript code sample for Number validation: for Client side validation
function isNumeric(obj, fieldName) {
var str = obj.value;
if ( ! isEmpty(obj, fieldName) ) {
if ( ! ValidateNumeric(obj.value) ) {
alert(fieldName + " can have only numeric values.");
obj.value = "";
obj.focus();
return false;
}
else {
//obj.value = parseInt(str);
return true;
}
}
else {
return false;
}
return true;
}
function isEmpty(obj, fieldName) {
var str = obj.value;
if ( ! ValidateNotEmpty(str) ) {
alert(fieldName + " is a mandatory field.");
obj.value = "";
obj.focus();
return true;
}
return false;
}
if ( ! isNumeric (document.formName.fieldName, 'FieldDisplayName') ) {
return false;
}
The Javat code sample for Number validation: for Server side validation
public static boolean isNumeric(String sTextString) {
boolean bResult = false;
Pattern p = Pattern.compile("^[0-9.]+$");
Matcher m = p.matcher(sTextString);
bResult = m.matches();
return bResult;
}
if ( ! ClassName.isNumeric(objBean.getFunctionId().trim()) ) {
objErrors.add(ActionErrors.GLOBAL_ERROR, new
ActionError("errors.database.error", "Selected Function Name in Form Input
is Not Valid."));
}
