JSF輸出樣式

<h:outputStylesheet>標籤用類型「text/css」呈現類型爲「link」的HTML元素。

此標籤將外部樣式表文件添加到JSF頁面。

以下JSF標籤 -

<h:outputStylesheet library="css" name="styles.css"  />

被渲染成如下HTML代碼 -

<link type="text/css" rel="stylesheet" 
   href="/helloworld/javax.faces.resource/styles.css.jsf?ln=css" />

例子

以下是文件：UserBean.java 中的代碼 -

package com.yiibai;

import java.io.Serializable;
import java.math.BigDecimal;
import java.util.ArrayList;
import java.util.Arrays;

import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;

@ManagedBean(name="book")
@SessionScoped
public class UserBean implements Serializable{
  private static final long serialVersionUID = 1L;
  String bookNo;
  String productName;
  BigDecimal price;
  int qty;
  public String getBookNo() {
    return bookNo;
  }
  public void setBookNo(String bookNo) {
    this.bookNo = bookNo;
  }
  public String getProductName() {
    return productName;
  }
  public void setProductName(String productName) {
    this.productName = productName;
  }

  public BigDecimal getPrice() {
    return price;
  }

  public void setPrice(BigDecimal price) {
    this.price = price;
  }

  public int getQty() {
    return qty;
  }

  public void setQty(int qty) {
    this.qty = qty;
  }

  private static final ArrayList<Book> bookList = 
    new ArrayList<Book>(Arrays.asList(

    new Book("1", "CSS", new BigDecimal("123.12"), 1),
    new Book("2", "HTML", new BigDecimal("321.12"), 2),
    new Book("3", "SQL", new BigDecimal("12333.33"), 8),
    new Book("4", "Javascript", new BigDecimal("1233.33"), 3),
    new Book("5", "Web", new BigDecimal("123.22"), 10)
  ));

  public ArrayList<Book> getBookList() {
    return bookList;
  }
  public String addAction() {
    Book book = new Book(this.bookNo, this.productName, 
      this.price, this.qty);
    bookList.add(book);
    return null;
  }
  public String deleteAction(Book book) {

    bookList.remove(book);
    return null;
  }

    public static class Book{

      String bookNo;
      String productName;
      BigDecimal price;
      int qty;

      public Book(String bookNo, String productName, 
          BigDecimal price, int qty) {
        this.bookNo = bookNo;
        this.productName = productName;
        this.price = price;
        this.qty = qty;
      }

      public String getBookNo() {
        return bookNo;
      }
      public void setBookNo(String bookNo) {
        this.bookNo = bookNo;
      }
      public String getProductName() {
        return productName;
      }
      public void setProductName(String productName) {
        this.productName = productName;
      }
      public BigDecimal getPrice() {
        return price;
      }
      public void setPrice(BigDecimal price) {
        this.price = price;
      }
      public int getQty() {
        return qty;
      }
      public void setQty(int qty) {
        this.qty = qty;
      }
    }

}

以下是文件： table-style.css 的代碼 -

.book-table-header{
  bbook-bottom:1px solid #BBB;
  padding:16px;
  color: red;
}

.book-table-odd-row{
  bbook-top:1px solid #BBB;
}

.book-table-even-row{
  bbook-top:1px solid #BBB;
}

以下是文件： index.xhtml 的代碼 -

運行測試

這裏使用NetBeans創建一個名稱爲：OutputStylesheet 的Web項目。並使用以提及的代碼文件。

Tomcat啓動完成後，在瀏覽器地址欄中輸入以下URL。

http://localhost:8084/OutputStylesheet/

訪問上面URL應該會看到以下結果 -
