javascript - 仅对所有 iPhone 和 IPADS 进行样式设置的 CSS 样式

Question

问题:我的图像在除 iPhone 以外的所有平台上都具有响应能力。

在安卓版网站上，下图没有歪斜:

在网站的 iphone 版本上，它正在炸毁图像，我不确定。

我认为以下内容可以解决除 IPHONES 和 IPADS 之外的倾斜问题

#homepage .carousel .item { 
    height: auto !important; 
} 

#homepage .carousel .item img { 
    min-width: 100% !important; 
    max-width: 100% !important; 
    height: auto !important; 
    position: relative !important; 
} 

.carousel-indicators { 
    bottom: 2%; 
} 

话虽这么说，我还发布了我所做的其余 css，以使其响应不同的尺寸:

#homepage .carousel .item img {

我使用以下站点定位 iPhone 和 iPad，但它对 iPhone 或 iPad 没有影响:http://stephen.io/mediaqueries/ .图像继续倾斜。

有没有办法检测网站何时显示在 iphone 和 ipad 上。一旦检测到它，调用另一个仅适用于 iphones 和 ipad 的 css 文件？

我能够找到一行代码来检测它是否在 iphone 上，但不确定如何为 iphone 和 ipad 修改它。我做了以下操作，但它似乎没有检测到是否检测到 iphone 或 ipad:

        <script language=javascript>
        if ((navigator.userAgent.match(/iPhone/i)) || (navigator.userAgent.match(/iPod/i)) || (navigator.userAgent.match(/iPad/i))) {
            <link rel="stylesheet" href="/Regal-en-us/includes/themes/MuraBootstrap3/assets/bootstrap/css/iphone.css">
        }
    </script>

如有任何帮助，我们将不胜感激。

谢谢

我使用以下方法检测用户使用的是 ipad 还是 iphone:

    <script language=javascript>
    if ((navigator.userAgent.match(/iPhone/i)) || (navigator.userAgent.match(/iPod/i)) || (navigator.userAgent.match(/iPad/i))) {
        document.getElementsByTagName('head')[0].insertAdjacentHTML('beforeend', '<link rel="stylesheet" href="/includes/themes/MuraBootstrap3/assets/bootstrap/css/iphone.css">');
        alert("Hello1.1!");
    }
</script>

它确实检测到 iphone 和 ipad。但是，未检测到我正在做的样式。以下是我为 iphone 和 ipad 设置轮播图片样式的样式:

#homepage .carousel .item { 
    height: auto !important; 
} 

#homepage .carousel .item img { 
    min-width: 100% !important; 
    max-width: 100% !important; 
    height: auto !important; 
    position: relative !important; 
} 

.carousel-indicators { 
    bottom: 2%; 
} 

/* Portrait and Landscape iphone and ipad*/
/*@media only screen 
  and (min-device-width: 375px) 
  and (max-device-width: 760px) 
  and (-webkit-min-device-pixel-ratio: 2) { 
    #homepage .carousel .item { 
        height: 139px !important; 
        margin-top:285px !important;
    }
}*/
@media screen and (max-width:768px) and (orientation:portrait) and (-webkit-max-device-pixel-ratio:0) { 
    #homepage .carousel .item img {
        /*min-width: 100% !important;
        /*width: 100% !important;*/
        height: 293px !important;*/
        position: relative !important;
        margin-top: 200px;
    }
}

如您所见，它没有检测到媒体查询，但它被 IPAD 和 IPHONE 识别，因为警报消失了。

如有任何帮助，我们将不胜感激。

在这一点上，我只想在 iphone 和 ipad 上看起来不错。我已经为此工作了一段时间，但没有解决方案或进展

您的想法是正确的，您只需将链接标记插入到 DOM 中即可。

function isAppleSafari(userAgent){
  var iPhone = userAgent.match(/iPhone/i) !== null;
  var Apple = userAgent.match(/Apple/i) !== null;
  var Mac = userAgent.match(/Mac/i) !== null;
  var iPod = userAgent.match(/iPod/i) !== null;
  var iOS = userAgent.match(/iOS/i) !== null;
  var Safari = userAgent.match(/Safari/i) !== null;
  return Safari && (iPhone || Apple || Mac || iPod || iOS);
}

// Use like this...
if(isAppleSafari(navigator.userAgent)){ 
  document.getElementsByTagName('head')[0].insertAdjacentHTML('beforeend', '<link rel="stylesheet" href="/Regal-en-us/includes/themes/MuraBootstrap3/assets/bootstrap/css/iphone.css">');
}

我用了 insertAdjacentHTML 这里把它放在<head>页面的。
