小编BIL*_*ILL的帖子

我有一些代码

<input type="checkbox" id="chk" value="value" />
<label for="chk">Value </label>
<br/>
<input type="button" id="But1" value="set value" />
<br />
<input type="button" id="But2" value="read checked" />

JavaScript的:

$(document).ready(function () {
    console.log("Ready ...");
    registerHandlers();

    function registerHandlers() {
        $('#But1').click(function () {
            $('#chk').prop('checked', !$('#chk').is(':checked'));
        });
        $('#But2').click(function () {
            var chk1 = $('#chk').is(':checked');
            console.log("Value : " + chk1);
        });

        $('input[type="checkbox"]').change(function () {
            var name = $(this).val();
            var check = $(this).prop('checked');
            console.log("Change: " + name + " to " + check);
        });
    }
});

我有这个类用于在Java中创建一个线程

package org.vdzundza.forms;

import java.awt.Graphics;
import java.awt.Graphics2D;

public class DrawThread extends Thread {
    private static final int THREAD_SLEEP = 500;
    public CustomShape shape;
    private Graphics g;

    public DrawThread(CustomShape shape, Graphics g) {
        this.shape = shape;
        this.g = g;
    }

    @Override
    public void run() {
        while (true) {
            try {
                Thread.sleep(THREAD_SLEEP);
                Graphics2D g2d = (Graphics2D) g;
                g2d.setColor(this.shape.getColor());
                g2d.fill(this.shape.getShape());
                System.out.println(String.format("execute thread: %s %s",
                        Thread.currentThread().getName(), this.getName()));
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }
}

控制台将以下文本显示为输出

execute thread: red rectangle Thread-2
execute …

我有一些表行

<tr class="b_row">
    <td>
        <div class="cpt">
            <h2>
                <a href="/ref/ref/1.html">example</a>
            </h2>
        </div>
    </td>
</tr>

<!--more elements -->

<tr class="b_row">
    <td>
        <div class="cpt">
            <h2>
                <a href="/ref/two/23.html">example N</a>
            </h2>
        </div>
    </td>
</tr>

我需要在属性中获取超链接.我用这个脚本

function openAll()
{
    $("tr.b_row").each(function(){
    var a_href = $('div.cpt').find('h2 a').attr('href');
    alert ("Href is: " + a_href);
}

问题:变量a_href总是/ ref/ref/1.html

我有功能

public static int func(int M,int N){
    if(M == 0 || N == 0) return M+N+1;
    return func(M-1, func(M, N-1));
}

我想我的版本1.2到1.3的angular-animate.js存在迁移问题.这是我的动画

'use strict';
angular.module('cookbook', ['ngAnimate'])
    .animation('.slide-down', function() {
        var NG_HIDE_CLASS = 'ng-hide';

        return {
            beforeAddClass: function(element, className, done) {
                alert('before add');
                if(className === NG_HIDE_CLASS) {
                    element.slideUp(done);
                }
            },
            removeClass: function(element, className, done) {
                if(className === NG_HIDE_CLASS) {
                    element.hide().slideDown(done);
                }
            }
        };
    });
