这对你管用。

我所做的是为您创建一个函数，并在$(window).load和$(window).resize中调用它-

var cloneFun = function() {
  if ($(window).width() <= 420) {
    $(".trust-datail").each(function(i) {
      var clonId = "#" + i,
        clon = $(this).clone();
      $(clonId).find('.clearfix').before(clon);
      $(this).addClass('mob-none');
    });
  } else {

    $(".trust-datail").removeClass('mob-none');
  }
};

$(window).load(function() {
  cloneFun();
});

$(window).resize(function() {
  cloneFun();
});

此函数检查窗口大小，如果小于420px，它将复制您的div并将其粘贴到.trust-wrap中

并且我使用.mob-none在移动视图中隐藏您的详细信息。

null

$(".trust-datail").hide();
$(".trust-wrap").each(function(i) {
  $(this).attr('id', +i);
});

$(".trust-datail").each(function(i) {
  $(this).addClass("tab_" + i);
});


$(".trust-wrap").click(function() {
  $(".trust-datail").slideUp();
  var id = $(this).attr('id');

  if ($(".tab_" + id).is(':visible')) {
    $(".tab_" + id).slideUp();
  } else {
    $(".tab_" + id).slideDown();
  }
});
$(".close-new").click(function() {
  $(this).parent(".trust-datail").slideUp();
});

var cloneFun = function() {
  if ($(window).width() <= 420) {
    $(".trust-datail").each(function(i) {
      var clonId = "#" + i,
        clon = $(this).clone();
      $(clonId).find('.clearfix').before(clon);
      $(this).addClass('mob-none');
    });
  } else {

    $(".trust-datail").removeClass('mob-none');
  }
};

$(window).load(function() {
  cloneFun();
});

$(window).resize(function() {
  cloneFun();
});

.trust-wrap {
