Question

我正在点击这个网址

http://localhost:8001/#/verifyMail?4c4e77a2

那时我做了

的console.log（$ stateParams）;

显示空对象

我的路线是

.state('mailVerification', {
        url: "/verifyMail?id",
          templateUrl: "app/views/common/emailVerification.html",
          controller: 'accountCtrl',
          data: {
              authorizedRoles: [USER_ROLES.all]
          }
      })

为什么我没有获得$ stateParams.id值？请帮帮我。

Answer 1

您需要解析数据。

private class BtnNewButtonActionListener implements ActionListener {

    public void actionPerformed(ActionEvent e) {

        Card card = B.pop(); //Card one is from Deck B, need to compare to the button

        int actionValue = Integer.parseInt(e.getActionCommand());
        int cardValue = (actionValue - 1) + (card.getSuitNumber() * 13);
        Card match = new Card(cardValue);

        System.out.println("Match " + match + " to " + card);

        if (card.equals(match)) {
            System.out.println("Winner");
        } else {
            System.out.println("Loser");
        }
    }

}

并在控制器内部：

    private Deck B = new Deck(); //B have 52 cards, and shuffled  

    /**

     */
    public static void main(String[] args) {
        EventQueue.invokeLater(new Runnable() {

                try {
                    CardGame window = new CardGame();
                    window.frame.setVisible(true);
                } catch (Exception e) {
                    e.printStackTrace();

        });
    }

    public CardGame() {

            JButton btn1 = new JButton(Integer.toString(index + 1));
            btn1.addActionListener(new BtnNewButtonActionListener());
            frame.getContentPane().add(btn1, gbc);

        }
    }

    private class BtnNewButtonActionListener implements ActionListener {

        public void actionPerformed(ActionEvent e) {

            Card card = B.pop(); //Card one is from Deck B, need to compare to the button

            int actionValue = Integer.parseInt(e.getActionCommand());
            int cardValue = (actionValue - 1) + (card.getSuitNumber() * 13);
            Card match = new Card(cardValue);

            System.out.println("Match " + match + " to " + card);

            if (card.equals(match)) {
                System.out.println("Winner");
            } else {
                System.out.println("Loser");
            }
        }

    }

    public static class Card {

        //Numerical equivalent of the suit and face

                System.exit(0);
            }
            suitNum = num / 13;
            faceNum = num % 13;
        }

        // Return a calculated value that combines suit and face numbers
        public int getTotalNumber() {
            return (this.suitNum * 13 + this.faceNum);
        }

        public int getFaceNumber() {
            return faceNum;
        }

        public int getSuitNumber() {
            return suitNum;
        }

        public String toString() {
            int num = getTotalNumber();
            String outStr = FACES[num % 13];
            outStr += " of ";
            outStr += SUITS[num / 13];
            return outStr;
        }

        @Override
        public int hashCode() {
            int hash = 7;
            hash = 97 * hash + this.suitNum;
            hash = 97 * hash + this.faceNum;
            return hash;
        }

        @Override
        public boolean equals(Object obj) {
            if (obj == null) {
                return false;
            }
            if (getClass() != obj.getClass()) {
                return false;
            }
            final Card other = (Card) obj;
            if (this.suitNum != other.suitNum) {
                return false;
            }
            if (this.faceNum != other.faceNum) {
                return false;
            }
            return true;
        }

    }

    public class Deck extends Stack<Card> {
        //pop method already in the stack 

        // Create a new shuffled deck
        public Deck() {
            for (int ii = 0; ii < 52; ii++) {
                push(new Card(ii));
            }
            Collections.shuffle(this);
        }

        // For debug purposes
        public void printDeck() {
            for (int ii = 0; ii < 52; ii++) {
                System.out.println(get(ii).toString());
            }
        }
    }

}

即使路由有参数，$ stateParams也会变为空值
