我经常需要在页面元素中存储少量引用,大多数时候是a <div>.我找不到太多关于创建自己的属性的有效性的文档.你有什么建议是最有效的方法,甚至可以做到这一点？如果是这样,我可以使用jQuery的attr()调用来获取引用吗？

例如: <div class="sample" dataref="Sample Data Reference"></div>

如何使用WebClient.DownloadFile摘要式身份验证和查询字符串？

当我尝试使用它时,我得到401响应.

这是Apache错误日志:

[Tue Jun 24 17:31:49 2014] [error] [client x.x.x.x] Digest: uri mismatch - </file-1.php> does not match request-uri </file-1.php?since=1403587422>

以下是我尝试下载文件的方法:

Uri uri = new Uri("http://example.com/file-1.php?since=1403587422");
WebClient webClient = new WebClient();
CredentialCache credentialCache = new CredentialCache();
credentialCache.Add(
  new Uri(uri.GetLeftPart(UriPartial.Authority)),
  "Digest",
  new NetworkCredential("username", "password")
);
webClient.Credentials = credentialCache;
webClient.DownloadFile(uri, file.OutputFile);

如何调试没有错误消息的错误？

加载PHP页面时,我在Firefox中收到此错误.

The connection to the server was reset while the page was loading.

它没有说明除了它似乎是Apache崩溃之外的原因.

Apache错误日志显示:

我有一个联系消息系统的查询,我做的连接越多,指数越来越慢.

表结构基本上是联系表和联系人字段表.

查询多次加入联系人字段表,对于每次加入,它需要两倍的时间.

这是查询.

SELECT  SQL_CALC_FOUND_ROWS
    `contact_data`.`id`,
    `contact_data`.`name`,
    `fields0`.`value` AS `fields0`,
    `fields1`.`value` AS `fields1`,
    `fields2`.`value` AS `fields2`,
    ...etc...

如何在Web应用程序的客户端解密某些加密数据？

例如

• 数据以加密方式存储在服务器上.
• 它是使用公共GPG密钥加密的.
• 服务器将加密的内容发送给客户端.
• 客户端需要使用本地私钥解密它.

可能我可以将私钥传递给浏览器并使用Javascript来解密数据.

如何从PHPUnit的代码覆盖范围中排除基目录？

这是我的phpunit.xml

<?xml version="1.0" encoding="UTF-8"?>
<phpunit bootstrap="include.php"
         stopOnError="false"
         stopOnFailure="false"
         stopOnIncomplete="false"
         stopOnSkipped="false">
    <testsuite name="MyProject">
        <directory>classes/*</directory>
    </testsuite>
    <logging>
        <log type="coverage-html" target="../reports/coverage" charset="UTF-8" yui="true" highlight="false" lowUpperBound="35" highLowerBound="70"/>
        <log type="coverage-xml" target="../reports/coverage.xml"/>
        <log type="test-xml" target="../reports/logfile.xml" logIncompleteSkipped="false"/>
        <log type="testdox-html" target="../reports/testdox.html"/>
        <log type="testdox-text" target="../reports/testdox.txt"/>
    </logging>
</phpunit>

输出时,它包括所有基本目录,如:

c:\work\some\path\MyProject

如何使其仅包括...\MyProject\*代码覆盖率输出？

如何使用Respect Validation获得多个自定义错误消息.

我有一些输入,我想针对多个验证器进行验证.我希望每次验证都有自定义错误消息.

这是我试过的:

try {
    Respect\Validation\Validator::create()
        ->key('foo',
            v::length(20)->setName('bar')->setTemplate('Custom length message.')
             ->alnum()->setName('baz')->setTemplate('Custom alnum message.')
        )
        ->assert([
            'foo' => 'Hello, world!',
        ]);
} catch (Respect\Validation\Exceptions\ValidationException $exception) {
    $errors = $exception->findMessages([
        'bar',
        'baz',
    ]);
    var_dump($errors);
}

输出是:

array (size=2)
  'bar' => string '' (length=0)
  'baz' => string 'Custom alnum message.' (length=21)

我希望它输出两个自定义错误消息.

Idealy我可以获得1个输入的消息数组,如:

var_dump($exception->findMessages(['foo']));

会给我:

array (size=1)
  'foo' => 
    array (size=2)
      0 => string 'Custom length message.' (length=22)
      1 => string 'Custom alnum message.' (length=21)

这个问题看起来像是杂草.

这个错误在IE10/11中意味着什么:

Error: Could not complete the operation due to error 800a025e. 

我该如何调试它？

它说它的这一行:

this.nativeSelection.removeAllRanges();

有没有办法嵌套jQuery sortables？与嵌套容器一样,不是嵌套列表.

<div class="container">
    <div class="item"></div>
    <div class="item"></div>
    <div class="item"></div>
</div>
<div class="container">
    <div class="item"></div>
    <div class="container">
        <div class="item"></div>
        <div class="item"></div>
        <div class="item"></div>
    </div>
    <div class="item"></div>
</div>

$('.container').sortable({
    connectWith: '.container'
});

http://jsfiddle.net/ExLqv/2/

这个例子非常有效,但是当我删除嵌套容器时,我收到一个错误:

Uncaught HierarchyRequestError: A Node was inserted somewhere it doesn't belong. 

我认为这是因为当拖动container它时,它位于鼠标下方,所以当我放下它时,它会尝试将它放在自身内部.

我有一个工作,虽然不理想所以问题仍然存在.

$('.container').sortable({
    connectWith: '.container:not(.ui-sortable-helper)',
    tolerance: "pointer",
    cursorAt: { left: -50 }
});

是否有纯粹的JS等同于jQuery .is()(仅限现代浏览器).

我知道有querySelector,但我想检查节点本身,而不是找到子节点.
