Question

我阻止了8个容器（project_block）和光滑的滑块。另外在底部我有一个小按钮。

滑动滑块仅在990像素中触发。当它开始滑动时，我需要删除底部的按钮。但是如何删除他不会为空的按钮。？

当我使用方法btn.remove()按钮移除时，我会在我的滑块中停留，看看左侧的白色区域

请帮助

以下是Codepen代码段

＆＃13;

$(window).on('load', function() {
  if ($(window).width() < 990) {
    $('.container-slick').slick({
      centerMode: true,
      infinite: true,
      prevArrow: false,
      nextArrow: false,
      speed: 200,
      slidesToShow: 2,
      slidesToScroll: 1,
      autoplay: true,
      responsive: [{
        breakpoint: 568,
        settings: {
          slidesToShow: 1
        }
      }]
    });
  }
});
$(window).on('resize', function() {
  if ($(window).width() < 990) {
    $('.container-slick').not('.slick-initialized').slick({
      centerMode: true,
      infinite: true,
      prevArrow: false,
      nextArrow: false,
      speed: 200,
      slidesToShow: 2,
      slidesToScroll: 1,
      responsive: [{
        breakpoint: 568,
        settings: {
          slidesToShow: 1
        }
      }]
    });
  } else {
    $(".container-slick.slick-initialized").slick("unslick");
  }
});

Answer 1

1）考虑使用css media query将display: none设置为您要删除的按钮

2）考虑使用JS调整大小时将样式display: none添加到按钮（非常糟糕）

3）当你只需要隐藏它时，考虑不要用js删除按钮

4）在发布到SO之前考虑搜索网页

------- --------编辑

刚试过以下，它成功隐藏了btn

@media screen and (max-width: 990px){
  .btn_container {
    display: none !important;
  }
}

如何使用js正确删除按钮
