推荐答案

如果您正在DataView中寻找分页，那么启用分页所需要做的就是在数据视图上调用setItemsPerPage(int).

If you are looking for pagination in DataView then ,all you need to do to enable paging is to call setItemsPerPage(int) on the dataview.

检查以下示例 JAVA 代码

    public class RepeatingPage extends BasePage
{
    private static final long serialVersionUID = 1L;

    /**
     * Constructor
     */
    public RepeatingPage()
    {
        Iterator<Contact> contacts = new ContactDataProvider().iterator(0, 10);

        RepeatingView repeating = new RepeatingView("repeating");
        add(repeating);

        int index = 0;
        while (contacts.hasNext())
        {
            AbstractItem item = new AbstractItem(repeating.newChildId());

            repeating.add(item);
            Contact contact = contacts.next();

            item.add(new ActionPanel("actions", new DetachableContactModel(contact)));
            item.add(new Label("contactid", String.valueOf(contact.getId())));
            item.add(new Label("firstname", contact.getFirstName()));
            item.add(new Label("lastname", contact.getLastName()));
            item.add(new Label("homephone", contact.getHomePhone()));
            item.add(new Label("cellphone", contact.getCellPhone()));

            final int idx = index;
            item.add(AttributeModifier.replace("class", new AbstractReadOnlyModel<String>()
            {
                private static final long serialVersionUID = 1L;

                @Override
                public String getObject()
                {
                    return (idx % 2 == 1) ? "even" : "odd";
                }
            }));

            index++;
        }
    }
}

HTML 代码

<wicket:extend xmlns:wicket="http://wicket.apache.org">
<br/><br/>

<table cellspacing="0" class="dataview">
    <tr>
        <th>Actions</th>
        <th>ID</th>
        <th>First Name</th>
        <th>Last Name</th>
        <th>Home Phone</th>
        <th>Cell Phone</th>
    </tr>
    <tr wicket:id="repeating">
        <td><span wicket:id="actions">[actions]</span></td>
        <td><span wicket:id="contactid">[contactid]</span> </td>
        <td><span wicket:id="firstname">[firstname]</span></td>
        <td><span wicket:id="lastname">[lastname]</span></td>
        <td><span wicket:id="homephone">[homephone]</span></td>
        <td><span wicket:id="cellphone">[cellphone]</span></td>
    </tr>
</table>

</wicket:extend>
