Hi Yasser,

Thanks for your useful suggestion!
It works with:
public class RegisterAction {
...
   public Country getSelectedCountryObject(String selectedCountry) {
  for (Country c : countryList) {
 if (String.valueOf(c.getCountryId()).equals(selectedCountry))
return c;
  }
  return new Country(0, "");
   }
...
}

RE: How to display both selected key and value of s:select

Hi Albert,

The simplest method can be something like this:

public class RegisterAction {
...
public Country getSelectedCountryObject() {
foreach (c in countryList) if(c.countryId==selectedCountry) return c;
}
...
}



Thanks for using Struts.

Kind Regards.

How to display both selected key and value of s:select

2018-12-22 Thread albert kao 
I want to display both selected key and value of s:select.
e.g. for the following codes, after I select
key="2", value="Canada"
and press the submit button.
Only the key "Country: 2" is displayed in the registerResult.jsp as desired.
How to make the value "Canada" to display also in the browser?

public class RegisterAction extends ActionSupport {
private String country, selectedCountry;
private ArrayList countryList;

public RegisterAction() {
countryList = new ArrayList();
countryList.add(new Country(1, "India"));
countryList.add(new Country(2, "Canada"));
countryList.add(new Country(3, "US"));
return;
}
}

public class Country {
private int countryId;
private String countryName;
public Country(int countryId, String countryName)
{
this.countryId = countryId;
this.countryName = countryName;
}
public int getCountryId() {
return countryId;
}
public void setCountryId(int countryId) {
this.countryId = countryId;
}
public String getCountryName() {
return countryName;
}
public void setCountryName(String countryName) {
this.countryName = countryName;
}
}

register.jsp








registerResult.jsp
Country: 
selectedCountry: 
CountryListAll: 
CountryListAll2: 
CountryList: 
CountryList.get 


http://localhost:8080/Struts2Example/register.action
