不行。请帮助。

Answer 1

您似乎希望在.resize()事件中看到此内容：

$(function(){ // <----doc ready.
    $(window).resize(function(){ //<----resize event bound on window.
      if ($(window).width() <= 480) {
          $(".content").hide(); 
      }
    }).resize(); // <----triggered the event on doc ready.
});

Answer 2

在$（window）.resize（）和$（document）.ready（）事件上显示和隐藏.content块。 $（window）.resize（）的示例：

$(window).resize(function() {
    $(".content").toggle($(window).width() >= 480);
});

Answer 3

if ($(window).width() <= 480) {
  $(".content").hide();
}

<div class="content">
  <div class="ui-menu-item"><span style="color:white" class="glyphicon glyphicon-phone" aria-hidden="true"> 0(333)3333333</span></div>
   <a href="mailto:info@bbbbbbbweb.com"><div class="ui-menu-item"><span style="color:white" class="glyphicon glyphicon-envelope" aria-hidden="true"> info@bldkcomweb.com</span></div></a>
</div>
