我有一个我要为手机和平板电脑禁用的模型，但是想要保留更大的屏幕。我在CSS媒体查询中尝试了visibility:hidden和display:none，但结果却很奇怪。我想我需要禁用onClick功能，但无法弄清楚如何只为较小的屏幕做到这一点。

由于您使用Javascript来显示模型，因此只需在实际显示之前检查设备是否符合您的条件。我已根据另一个SO帖子编写了一个自定义功能，以检查设备是否可移动。然后你还可以检查屏幕宽度是否允许。

用以下内容替换您的Javascript：

$(function() {
    $('.pop').on('click', function() {
      $('.imagepreview').attr('src', $(this).find('img').attr('src'));
      if($( window ).width()<800 || isMobile()){
         //do substitute operation for mobile screens
      } else {
         $('#imagemodal').modal('show');
      }   
    });   
});
function isMobile() {
  var isMobile = false; //initiate as false
  // device detection
  if (/(android|bb\d+|meego).+mobile|avantgo|bada\/|blackberry|blazer|compal|elaine|fennec|hiptop|iemobile|ip(hone|od)|ipad|iris|kindle|Android|Silk|lge |maemo|midp|mmp|netfront|opera m(ob|in)i|palm( os)?|phone|p(ixi|re)\/|plucker|pocket|psp|series(4|6)0|symbian|treo|up\.(browser|link)|vodafone|wap|windows (ce|phone)|xda|xiino/i.test(navigator.userAgent) || /1207|6310|6590|3gso|4thp|50[1-6]i|770s|802s|a wa|abac|ac(er|oo|s\-)|ai(ko|rn)|al(av|ca|co)|amoi|an(ex|ny|yw)|aptu|ar(ch|go)|as(te|us)|attw|au(di|\-m|r |s )|avan|be(ck|ll|nq)|bi(lb|rd)|bl(ac|az)|br(e|v)w|bumb|bw\-(n|u)|c55\/|capi|ccwa|cdm\-|cell|chtm|cldc|cmd\-|co(mp|nd)|craw|da(it|ll|ng)|dbte|dc\-s|devi|dica|dmob|do(c|p)o|ds(12|\-d)|el(49|ai)|em(l2|ul)|er(ic|k0)|esl8|ez([4-7]0|os|wa|ze)|fetc|fly(\-|_)|g1 u|g560|gene|gf\-5|g\-mo|go(\.w|od)|gr(ad|un)|haie|hcit|hd\-(m|p|t)|hei\-|hi(pt|ta)|hp( i|ip)|hs\-c|ht(c(\-| |_|a|g|p|s|t)|tp)|hu(aw|tc)|i\-(20|go|ma)|i230|iac( |\-|\/)|ibro|idea|ig01|ikom|im1k|inno|ipaq|iris|ja(t|v)a|jbro|jemu|jigs|kddi|keji|kgt( |\/)|klon|kpt |kwc\-|kyo(c|k)|le(no|xi)|lg( g|\/(k|l|u)|50|54|\-[a-w])|libw|lynx|m1\-w|m3ga|m50\/|ma(te|ui|xo)|mc(01|21|ca)|m\-cr|me(rc|ri)|mi(o8|oa|ts)|mmef|mo(01|02|bi|de|do|t(\-| |o|v)|zz)|mt(50|p1|v )|mwbp|mywa|n10[0-2]|n20[2-3]|n30(0|2)|n50(0|2|5)|n7(0(0|1)|10)|ne((c|m)\-|on|tf|wf|wg|wt)|nok(6|i)|nzph|o2im|op(ti|wv)|oran|owg1|p800|pan(a|d|t)|pdxg|pg(13|\-([1-8]|c))|phil|pire|pl(ay|uc)|pn\-2|po(ck|rt|se)|prox|psio|pt\-g|qa\-a|qc(07|12|21|32|60|\-[2-7]|i\-)|qtek|r380|r600|raks|rim9|ro(ve|zo)|s55\/|sa(ge|ma|mm|ms|ny|va)|sc(01|h\-|oo|p\-)|sdk\/|se(c(\-|0|1)|47|mc|nd|ri)|sgh\-|shar|sie(\-|m)|sk\-0|sl(45|id)|sm(al|ar|b3|it|t5)|so(ft|ny)|sp(01|h\-|v\-|v )|sy(01|mb)|t2(18|50)|t6(00|10|18)|ta(gt|lk)|tcl\-|tdg\-|tel(i|m)|tim\-|t\-mo|to(pl|sh)|ts(70|m\-|m3|m5)|tx\-9|up(\.b|g1|si)|utst|v400|v750|veri|vi(rg|te)|vk(40|5[0-3]|\-v)|vm40|voda|vulc|vx(52|53|60|61|70|80|81|83|85|98)|w3c(\-| )|webc|whit|wi(g |nc|nw)|wmlb|wonu|x700|yas\-|your|zeto|zte\-/i.test(navigator.userAgent.substr(0, 4))) isMobile = true;

完整的工作代码：

如果模式是移动设备或屏幕尺寸小于800像素，模式将不会显示。根据需要调整到您的设置。点击run code snippet查看其实际效果！

感谢L.Dia提及屏幕尺寸检查。我添加了支票。

答案 1 :(得分：1)

随着冰人的回复 您也可以根据宽度取消绑定按钮，或者它是否是平板电脑/手机：

if( isMobile() || (screen.width <= 800)) {
            $(#yourbutton).unbind('click');
        }

使用css根据宽度更改按钮的外观，用户不会想要点击。

答案 2 :(得分：0)

我假设你正在使用Bootstrap。如果是这样，您可以使用本地隐藏类引导程序，如 hidden-xs 等。或者，您可以使用可见性类，如 visible-lg ;由于Bootstrap是移动的第一个框架，因此您的模式不会显示其他大屏幕设备。对于您的方案，这工作正常。

<div class="modal fade visible-lg" id="imagemodal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
  ...
</div>

如果您仍然坚持使用JavaScript解决方案，仍然假设您正在使用Bootstrap，那么您使用的是jQuery，这将获得窗口宽度并允许您控制事件。

$(document).ready(function () {
            var $window = $(window);

            function checkWidth() {
                var windowsize = $window.width();
                if (windowsize < 1200) {
                    $(".pop").click(function (event) {
                        event.preventDefault();
                    });
                }

                else {
                    $(function () {
                        $('.pop').on('click', function () {
                            $('.imagepreview').attr('src', $(this).find('img').attr('src'));
                            $('#imagemodal').modal('show');
                        });
                    });
                }
            }

            checkWidth();
            $(window).resize(checkWidth);
        });
