Re: How to add and remove css classes the right way?

[ncollette]

Obviously this is an old thread, but I just wanted to throw out another way
to remove a css class whilst preserving any existing css classes.

new SimpleAttributeModifier(class,
String.valueOf(this.getMarkupAttributes().get(class)).replaceFirst(edit,
));

In the case above - edit was the class I was removing.

 Hi Folks,

 I'am getting totally confused how to add and remove css classes to and form
 my text-input-fields on ajax-form-validation.

 At first i try to add two css classes step by step:

 IteratorFeedbackMessage iter =
 Session.get().getFeedbackMessages().messages(getFeedbackMessageFilter()).iterator();
 if(iter.hasNext()){
 indicatorFor.add(new SimpleAttributeModifier(class,validation_error));
 indicatorFor.add(new SimpleAttributeModifier(class, test));
 }

 But gets the Markup only with class='test' 

 How can i add more than one value to class?

 And how can i remove one special css-class from an component if the
 validation is okay to this field?


 Thanks in Advance for any help.

Hello Martin ;)

i tired

indicatorFor.add(new AttributeModifier(class,new
ModelString(validation_error)));
inicatorFor.add(new AttributeModifier(class,new ModelString(test)));

but in the markup no class attribute appears?

Re: How to add and remove css classes the right way?

[MattyDE]

Ah i did it . but is this the best way?

@Override
protected void onValidate() {   
super.onValidate();

visitFormComponents(new FormComponent.IVisitor() {

@Override
public Object formComponent(IFormVisitorParticipant 
formComponent) {
Component _c = (Component)formComponent;

if(formComponent instanceof 
IValidatingComponent){  



if(((IValidatingComponent)_c).getField().hasErrorMessage()){
AttributeAppender _attr = new 
AttributeAppender(class,new
ModelString(validation_error),  ){
@Override
public boolean 
isTemporary() {return true; }
};



((IValidatingComponent)_c).getField().add(_attr);   

}

}
return _c;
}
});


}
