com.missiondata.oss.lakeshore.Validator
- Direct Known Subclasses:
- RequiredField
- public abstract class Validator
- extends java.lang.Object
'Validate' a filed on second use
First attempt at pulling validation up into the framework. Time will tell if it will stay and grow...
On example use of this is
In the render:
final boolean valid = validator.isValid();
if( !valid) cssClass("error");
tableRow(new F(){public void f(){
cssClass("label");
tableData(label);
cssClass("value");
tableData(new F(){public void f(){
textInputOn(model, property);
if(!valid)
{
cssClass("error");
span(validator.getMessage());
}
}});
}});
In the submit handler
if(firstName.validate() & lastName.validate() & emailAddress.validate() & password.validate())
Note: Notice the aritmetic & instead of the boolean &&. This will ensure all validations are run
