我在wordpress网站上有以下代码
<article class="post-featured post-grid overlay overlay-ratio overlay-ratio-vertical parallax-video post-6792 post type-post status-publish format-video has-post-thumbnail hentry category-tech post_format-post-format-video post-visible" style="background-image: url(http://http://theoldcontinent.mgtestsite.com/wp-content/uploads/2017/07/Schermafbeelding-2017-07-10-om-18.54.13-530x300.jpg);" data-video="http://www.youtube.com/watch?v=GnfNta6SosA">
::before
<span class="overlay-label"><i class="icon icon-ribbon"></i></span>
<div class="overlay-container"></div>
<a href="http://theoldcontinent.mgtestsite.com/watch-the-1961-chevrolet-corvette-the-definition-of-cool/" class="overlay-link"></a>
</article>
我需要为移动overlay overlay-ratio overlay-ratio-vertical parallax-video删除这些类。我想使用jQuery或CSS。我希望代码简单地读取如下所示，因此移动设备的布局不同：
<article class="post-grid post-6800 post type-post status-publish format-standard has-post-thumbnail hentry category-last-night-in-sweden post-visible">
我需要使用哪个选择器？我试过这个，但没有任何反应：
$('article').removeClass("post-grid.overlay.overlay-ratio.overlay-ratio-vertical.parallax-video");
如何删除样式和数据视频。所有这一切只适用于移动设备？最大宽度：600px的
您可以使用此选项删除类
最终答案：
var window_weight = $(window).width();
if (window_weight <= 600) {
$('article').removeClass('post-grid overlay overlay-ratio overlay-ratio-vertical parallax-video');
}
还检查一下

}
选项1使用确切的类名，并在每个类名中添加空格
$('article').removeClass('post-grid overlay overlay-ratio overlay-ratio-vertical parallax-video');
选项2
您可以像这样使用多个removeClass
$("article").removeClass("post-grid").removeClass("overlay ").removeClass("overlay-ratio") ...;
我认为它应该是这样的
$('article').removeClass("post-grid overlay overlay-ratio overlay-ratio-vertical parallax-video");
改变“。”与“[空间]”
使用Modernizr（https://modernizr.com/docs）
Modernizr.mq允许您以编程方式检查当前浏览器窗口状态是否与媒体查询匹配。
在自定义脚本中使用此选项
if (Modernizr.mq('(max-width: 600px)')) {
//Code goes here
}
使用javascript检查设备
if( /Android|webOS|iPhone|iPad|iPod|BlackBerry|IEMobile|Opera Mini/i.test(navigator.userAgent) ) {
// add code for removing classes here
}
