Re: [S2] Pre-populating Checkboxes

[Nuwan Chandrasoma]

Hi,

I have done it like this.

// code in my action

   private String[] skill;

   public String[] getSkill() {
       return skill;
   }

   public void setSkill(String[] skill) {
       this.skill = skill;
   }

   public void prepare() throws Exception {
       skills = new ArrayList();
       skills.add("Java");
       skills.add("C#");
       skills.add("Spring");
       skills.add("Struts 2");

       skill = new String [2];

       skill[0] = "Java";
       skill[1] = "Spring";
   }
//jsp

<s:checkboxlist name="skill" list="skills"/>

Java and Spring check boxes will be selected.

Thanks,

Nuwan

Hi,

Thank you very much for your assistance, but I am already able to
display the checkboxes.  I guess my question wasn't very clear.  I need
to know how to redisplay the checked boxes a user selected in a previous
session.  So if there are five check boxes and the user selects three of
them and submits the form, how do I automatically check the three boxes
when the user returns the next day?  It appears that returning a string
array with the users selections is not working.

Thanks,
Dave

Hi,

This is how i do it, i have implemented the prepreable interface in my action and in prepare method, i populate the list i wanted to display in

as check box values.

eg:-

private List skills;

    public List getSkills() {
        return skills;
    }

    public void prepare() throws Exception {
        skills = new ArrayList();
        skills.add("Java");
        skills.add("C#");
        skills.add("Spring");
        skills.add("Struts 2");
    }

in jsp i have this tag and which will render 4 check boxes.

<s:checkboxlist name="skill" list="skills"/>

Thanks,

Nuwan

Hello,

I'm new to Struts 2 and I was wondering how to pre-populate checkboxes
with values from a database (or even hard-coded values).  I am

iterating

through an arraylist of hashmaps (description, type_cd) to create the
checkboxes in the form.  I then create a string array with the values

from a database to pre-populate, but it's not working.

* When the checkboxes are checked and the form is submitted, I am able
to capture the values (String array) properly.


JSP:
<s:iterator value="all_type_codes">
        <s:checkbox name="type_cd" fieldValue="%{type_cd}"/>
        <s:property value="description"/>
    <br>
</s:iterator>



Action Page:
public String[] getType_cd() {
    return type_cd;
}
public void setType_cd(String[] type_cd) {
    this.type_cd = type_cd;
}

// this is a test
// these are the options the user selected in a previous session
type_cd = new String[3];
type_cd[0] = "EQ";
type_cd[1] = "SF";
type_cd[2] = "SS";



Any help would be greatly appreciated!
