我正在尝试使用 html5 视频在滑块中显示视频。这与controls参数（显示控件）配合得很好。但是当我添加它时autoplay，它不会自动播放，所以我搜索了原因，发现 chome 只允许静音视频自动播放。
所以我muted向其中添加了参数，但是当我这样做时，我的整个视频变黑并且仍然无法自动播放。
为什么会这样呢？
我的代码：
<div class="r-slider-item">
<video width="100%" height="100%" autoplay muted loop>
<source src="assets/watertuin.mp4" type="video/mp4">
Your browser does not support the video tag.
</video>
<div class="container">
<div class="r-slider-top-content">
<h1 class="animated fadeInDown">RESERVEER <span>NU</span></h1>
<a href="#" class="btn btn-outlined animated fadeInUp"> Reserveren </a>
</div>
</div>
</div>
在 Firefox 和 IE 11 中它工作得很好。
我正在使用插件:charts.js
在悬停雷达图表(其中的子弹)时,会显示工具提示.我该如何删除它？
我有一个看起来像这样的字符串:
id_company=57&name=&address=&zip=&place=&phone=&mobile=&email=&birthdate=&birthplace=&bsn=&driver_expires=&role=&date_started=&contract=Tijdelijk&id_type=Paspoort&id_number=&id_expires=
上面的示例大部分都是空的(除了id_company).
我在jquery中序列化我的表单,如下所示:
var $serialized = $form.serialize();
在我的PHP中我这样做:
$jsonemployee = unserialize($_POST['serialized']);
之后我尝试打印它因为我期待一个数组:
echo '<pre>';
print_r($jsonemployee);
echo '</pre>';
但这没有给我什么.
我100%确定所有数据都已通过,在我的网络选项卡中,我看到发布的字符串,如果我只是回显字符串,则显示字符串.
如何从该字符串创建PHP数组？
我想要注释掉一些内联的css样式(在一些html标签内).我该怎么做呢？我是否使用CSS的/**/注释？或者<!-- -->对于HTML？
<span class="color_dark" style="top:20px;font-size: 17px;line-height: 0px;position: relative;">onbezorgd genieten van uw<br> haard of kachel</span>
这是我正在谈论的部分.我想评论一些样式属性.
I'm trying to shorten the speed of the autoplay on an owl carousel (I'm using owl carousel 1), but it's always stuck at 5 seconds. On the website (which is broken) it says you can add an integer after autoplay: but it doesn't matter what number I add, it always takes 5 seconds to play.
And I should mention that autoPlay (with capital P) does not work for me like it's shown on their website. Only if I use autoplay …

我需要在背景图像上添加透明的彩色图层.我尝试用rgba做这个但没有结果.
我现在得到的是:
page-heading {
background: rgba(36, 70, 105, 0.74) url("../images/samples/bg3.jpg") no-repeat fixed 50% 0px / cover;
opacity: 0.9;
position: relative;
text-align: center;
padding: 72px 0px;
}
我知道背景颜色是无法加载图像时的后备颜色.如何以正确的方式在其上添加图层？
