Struts 2 stextfield HTML input type text example
In struts 2 application you could define HTML input type text by using below s:textfield as shown below:
<s:textfield name=”firstName” key=”label.firstName”/>
or with attributes:
<s:textfield name=”firstName” size=”30″ maxlength=”50″ label=”First Name”/>
As you see above there is two way to define label:
- You could directly use label=”First Name” to give field name
- OR use key=”label.firstName” which will be read from resource bundle
