如何加载特定字体

适用于所有IPAD设备...... 1. IPAD应仅在所有IPAD设备Safari中加载 2.它应该加载所有OS浏览器+ IPAD所有设备Safari

CSS：

    1.//*IPAD this should load only in all IPAD Devices Safari
            @font-face {
            font-family:'Calibri';
              src: url('fonts/calibri.eot'); /*IE9 Compat Modes */
              src: url('fonts/calibri.eot?#iefix') format('embedded-opentype'), /* IE6-IE8 */
                 url('fonts/calibri.woff') format('woff'), /*Modern Browsers*/      
                  url('fonts/calibri.ttf') format('truetype'), /*Safari, Android, iOS */
                  url('fonts/calibri.svg#calibri') format('svg') /*Legacy iOS*/
            }
            //*IPAD Devices Safari



           2. // This should load in all OS browsers + IPAD all Devices Safari
            @font-face {
            font-family:'HelveticaNeueLT Std Lt';
            src: url('fonts/HelveticaNeueLTStd-Lt.eot'); /* IE9 Compat Modes */
            src: url('fonts/HelveticaNeueLTStd-Lt.eot?#iefix') format('embedded-opentype'), /* IE6-IE8 */
                url('fonts/HelveticaNeueLTStd-Lt.woff') format('woff'), /* Modern Browsers */
                 url('fonts/HelveticaNeueLTStd-Lt.ttf')  format('truetype'), /* Safari, Android, iOS */
                 url('fonts/HelveticaNeueLTStd-Lt.svg#HelveticaNeueLT Std Lt') format('svg') /* Legacy iOS */
            }
            // this should load in all OS browsers + IPAD all Devices Safari

您应该可以通过查看所用浏览器中的user agent字符串来执行此操作。

使用JavaScript，您可以阅读浏览器UA字符串，然后检查Apple浏览器中的常用字符串，并仅为它们提供可选代码。

<script type="text/javascript">
$(document).ready(function() {
  //check for iOS
  var is_uiwebview = /(iPhone|iPod|iPad).*AppleWebKit(?!.*Safari)/i.test(navigator.userAgent);
  var is_safari_or_uiwebview = /(iPhone|iPod|iPad).*AppleWebKit/i.test(navigator.userAgent);

  var ipad_only_fonts = "font-family:'Calibri'; url('fonts/calibri.woff') format('woff'), url('fonts/calibri.ttf') format('truetype'), url('fonts/calibri.svg#calibri') format('svg')";
  var all_apple_device_fonts = "font-family:'HelveticaNeueLT Std Lt'; url('fonts/HelveticaNeueLTStd-Lt.woff') format('woff'), url('fonts/HelveticaNeueLTStd-Lt.ttf') format('truetype'), url('fonts/HelveticaNeueLTStd-Lt.svg#HelveticaNeueLT Std Lt') format('svg')";
  if(is_uiwebview || is_safari_or_uiwebview) {
    // iphone/ipad/ipod detected

    // Add your fonts here
  }
});
</script>

adding CSS to your pages via Javascript有各种方法，但您可以通过以下摘录实现您的要求。

<script type="text/javascript">
$(document).ready(function() {
  //check for iOS
  var is_uiwebview = /(iPhone|iPod|iPad).*AppleWebKit(?!.*Safari)/i.test(navigator.userAgent);
  var is_safari_or_uiwebview = /(iPhone|iPod|iPad).*AppleWebKit/i.test(navigator.userAgent);

  var is_uiwebview_ipad = /(iPad).*AppleWebKit(?!.*Safari)/i.test(navigator.userAgent);
  var is_safari_or_uiwebview = /(iPad).*AppleWebKit/i.test(navigator.userAgent);

  if(is_uiwebview_ipad || is_safari_or_uiwebview_ipad) {
    // ipad detected
    $('body').css('@font-face', ipad_only_fonts); 
  }
  if(is_uiwebview || is_safari_or_uiwebview) {
    // iphone/ipod detected
    $('body').css('@font-face', ipad_only_fonts); 
  }
});
</script>

免责声明：我没有在实际设备上对此进行测试，但应该工作！
