o:highlight
is a helper component which highlights all invalid UIInput
components and the
associated labels by adding an error style class to them. Additionally, it by default focuses the first invalid
UIInput
component. The <o:highlight />
component can be placed anywhere in the view, as
long as there's only one of it. Preferably put it somewhere in the master template for forms.
<h:form> <h:inputText value="#{bean.input1}" required="true" /> <h:inputText value="#{bean.input1}" required="true" /> <h:commandButton value="Submit" action="#{bean.submit}" /> </h:form> <o:highlight />
The default error style class name is error
. You need to specify a CSS style associated with the class
yourself. For example,
label.error { color: #f00; } input.error, select.error, textarea.error { background-color: #fee; }
You can override the default error style class by the styleClass
attribute:
<o:highlight styleClass="invalid" />
You can disable the default focus on the first invalid input element setting the focus
attribute.
<o:highlight styleClass="invalid" focus="false" />
