我是Wicket的新手。在第一次使用wicket datatable之后,我实现了wicket:panel和wicket:容器被添加到HTML中。但是,我根本没有任何标记面板或容器。我需要一些帮助来确保HTML不包含不必要的wicket标记。感谢!!!
HTML代码
<!DOCTYPE html>
<html lang="en"
xml:lang="en"
xmlns:wicket="http://wicket.apache.org>
<head>
<title> Wicket test </title>
</head>
<body>
<table cellspacing="0" wicket:id="table"></table>
</body>
</html>
Java代码
import java.util.ArrayList;
import java.util.List;
import org.apache.wicket.markup.html.WebPage;
import org.apache.wicket.extensions.markup.html.repeater.data.table.DefaultDataTable;
import org.apache.wicket.extensions.markup.html.repeater.data.table.IColumn;
import org.apache.wicket.extensions.markup.html.repeater.data.table.PropertyColumn;
import org.apache.wicket.model.Model;
public class TestPage extends WebPage {
public TestPage() {
final UserProvider userProvider = new UserProvider();
List<IColumn<UserProvider.Contact, String>> columns = new ArrayList<IColumn<UserProvider.Contact, String>>(2);
columns.add(new PropertyColumn<UserProvider.Contact, String>(new Model<String>("First Name"), "name.first", "name.first"));
columns.add(new PropertyColumn<UserProvider.Contact, String>(new Model<String>("Last Name"), "name.last", "name.last"));
DefaultDataTable<UserProvider.Contact, String> dataTable = new DefaultDataTable<UserProvider.Contact, String>("table", columns, userProvider, 10);
add(dataTable);
}
}
UserProvider的Java代码
import java.util.*;
import java.io.Serializable;
import org.apache.wicket.extensions.markup.html.repeater.data.sort.SortOrder;
import org.apache.wicket.extensions.markup.html.repeater.util.SortableDataProvider;
import org.apache.wicket.model.AbstractReadOnlyModel;
import org.apache.wicket.model.IModel;
import org.apache.wicket.model.PropertyModel;
public Class UserProvider extends SortableDataProvider {
class SortableDataProviderComparator implements Comparator<Contact>, Serializable {
public int compare(final Contact o1, final Contact o2) {
PropertyModel<Comparable> model1 = new PropertyModel<Comparable>(o1, (String) getSort().getProperty());
PropertyModel<Comparable> model2 = new PropertyModel<Comparable>(o2, (String) getSort().getProperty());
int result = model1.getObject().compareTo(model2.getObject());
if (!getSort().isAscending()) {
result = -result;
}
return result;
}
}
private List<Contact> list = new ArrayList<Contact>();
private SortableDataProviderComparator comparator = new SortableDataProviderComparator();
public UserProvder() {
setSort("name.first", SortOrder.ASCENDING);
list.add(new Contact(new Name("Abbie", "Zed")));
list.add(new Contact(new Name("Benny", "Yellen")));
list.add(new Contact(new Name("Charles", "Wukong")));
list.add(new Contact(new Name("Dennis", "Rose")));
list.add(new Contact(new Name("Elaine", "Poppy")));
list.add(new Contact(new Name("Peter", "Jax")));
}
public Iterator<Contact> model(long first, long count) {
List<Contact> newList = new ArrayList<Contact>(list);
Collections.sort(newList, comparator);
return newList.subList((int) first, (int) (first + count)).iterator();
}
public IModel<Contact> model(final Object object) {
return new AbstractReadOnlyModel<Contact>() {
@Override
public Contact getObject() {
return (Contact) object;
}
};
}
public long size() {
return list.size();
}
class Contact implements Serializable {
private final Name name;
public Contact(final Name name) {
this.name = name;
}
public Name getName() {
return name;
}
}
class Name implements Serializable {
private String firstName;
private String lastName;
public Name(final String fName, final String lName) {
firstName = fName;
lastName = lName;
}
public String getFirst() {
return firstName;
}
public String getLast() {
return lastName;
}
public setFirst(final String firstName) {
this.firstName = firstName;
}
public setLast(final String lastName) {
this.lastName = lastName;
}
}
}
上面的Java代码来自一些在线示例。从代码,wicket:panel和wicket:容器没有被使用;但是,一旦部署了这个webapp。客户端接收带有unsed wicket标签的HTML页面。
答案 0 :(得分:4)
在Application类的init()方法中,调用
getMarkupSettings().setStripWicketTags(false);
您还可以使用setStripComments()
从结果HTML中删除评论,并使用setCompressWhitespace()
