我有一系列复选框,通过ajax一次加载100个.

我需要这个jquery允许我按下按钮检查屏幕上的所有内容.如果加载了更多,并按下了按钮,或许可以关闭所有关闭,然后再次按下切换所有重新打开.

这就是我所拥有的,显然它不适合我.

$(function () {
 $('#selectall').click(function () {
  $('#friendslist').find(':checkbox').attr('checked', this.checked);
 });
});

按钮是#selectall,复选框是类.tf,它们都驻留在一个父div中#check,在div中调用div #friend,在div中调用#friendslist

例:

<div id='friendslist'>
    <div id='friend'>
        <div id='check'>
            <input type='checkbox' class='tf' name='hurr' value='durr1'>
        </div>
    </div>
    <div id='friend'>
        <div id='check'>
            <input type='checkbox' class='tf' name='hurr' value='durr2'>
        </div>
    </div>
    <div id='friend'>
        <div id='check'>
            <input type='checkbox' class='tf' name='hurr' value='durr3'>
        </div>
    </div>
</div>

<input type='button' id='selectall' value="Select All">

我是d3.js或java的新手.我正在使用http://bl.ocks.org/1093025中的缩进树示例.我花了两个小时才能在我的本地计算机上工作,所以这应该让你了解我的技能水平.

我打开了flare.json文件并开始搞乱它并且能够成功地操作它.看起来像这样

{
    "name": "Test D3",
    "children": [
        {
            "name": "News",
            "children": [
                {
                    "name": "CNN",
                    "size": 1000
                },
                {
                    "name": "BBC",
                    "size": 3812
                }
            ]
        },
        {
            "name": "Blogs",
            "children": [
                {
                    "name": "Engaget",
                    "size": 3938
                }
            ]
        },
        {
            "name": "Search",
            "children": [
                {
                    "name": "Google",
                    "size": 3938
                },
                {
                    "name": "Bing",
                    "size": 3938
                }
            ]
        }
    ]
}

我现在想做的是尝试添加超链接.例如,我希望能够点击"CNN"并转到CNN.com.我可以对flare.json进行修改吗？

我有以下代码创建一个ImageButton并在单击时播放声音:

ImageButton SoundButton1 = (ImageButton)findViewById(R.id.sound1);
SoundButton1.setImageResource(R.drawable.my_button);

SoundButton1.setOnTouchListener(new OnTouchListener() {
    public boolean onTouch(View v, MotionEvent event) {
        if (event.getAction() == MotionEvent.ACTION_DOWN ) {
            mSoundManager.playSound(1);
            return true;
        }

        return false;
    }
});

问题是我希望按下它时ImageButton上的图像会发生变化.OnTouchListener似乎覆盖了触摸并且不允许图像更改.一旦我删除了OnTouchListener,ImageButton会在按下时切换到不同的图像.关于如何在仍然使用OnTouchListener时在ImageButton上更改图像的任何想法？非常感谢你!

我将JAVA_HOME变量设置为指向jdk,并将%JAVA_HOME%\ bin添加到Path变量中.但是,我的蚂蚁脚本无法找到jdk.它正在查找Java编译器的错误文件夹.这是我得到的错误.

com.sun.tools.javac.Main不在类路径上.也许JAVA_HOME并没有指向JDK.它目前设置为C:\Program Files\Java\jre6

我设定了我的 JAVA_HOME=C:\Program Files (x86)\Java\jdk1.7.0

我究竟做错了什么？请帮忙!

我们在azure上使用DocumentDB.我们有一个包含7个集合的数据库,每个集合最多有15个记录.它不需要太多存储空间.

只有少数开发人员正在使用此数据库实例.因此流量也低于平均水平.

该服务器仍然每天使用67,600个RU.DocumentDB设置必定存在一些问题.那么,我正在寻找方向来准确分析这些RU的收费方式以及如何减少它们？

我正在使用capyfony + symfony2.
