javascript - 如何为响应式设计禁用 javascript

Question

我一直在为我网站的幻灯片背景使用超大型 jQuery。我正在使网站响应并使用 css 媒体查询。

我希望能够在低于 480 像素时禁用脚本。

这是实际 slider 背景的脚本

$(document).ready(function(){

         jQuery(function($){

            $.supersized({

                // Functionality
                slideshow               :   1,          // Slideshow on/off
                autoplay                :   0,          // Slideshow starts playing automatically
                start_slide             :   1,          // Start slide (0 is random)
                stop_loop               :   0,          // Pauses slideshow on last slide
                random                  :   0,          // Randomize slide order (Ignores start slide)
                slide_interval          :   3000,       // Length between transitions
                transition              :   6,          // 0-None, 1-Fade, 2-Slide Top, 3-Slide Right, 4-Slide Bottom, 5-Slide Left, 6-Carousel Right, 7-Carousel Left

                mouse_scrub             :   0

            });
        });

我想我可以通过使用 css 来简单地做到这一点，例如在我的媒体查询中只需将 #supersized as display:none

这是不好的做法吗，因为它仍然会运行脚本，最好以某种方式禁用它吗？

正如其他人所提到的，您可以使用大量的 jQuery 插件。但是，如果您只想使用普通的 jQuery，您也可以随心所欲。

可以使用jquery中的resize方法来检测窗口的大小。

$(window).resize(function() {
   if ($(this).width() > 480) {
      // call supersize method
   }
});

然后在准备好文档时，只需确保调用调整大小窗口，以便它最初会调用或不调用该方法，具体取决于您窗口的当前大小:

$(document).ready(function() {
   $(window).resize();
});

PS > 如果您不需要每次调整窗口大小时都运行此脚本，而是仅在它达到 480 像素以下时运行，则可以在脚本需要禁用或启用后进行轻微修改以取消绑定(bind)调整大小方法。
