带有CSS滑块的导航按钮

标签: javascript jquery html css css3

我有一个CSS滑块,除了两件我无法弄清楚的东西外,大部分都有效。第一个是,如何使我的滑块导航按钮按照我的方式工作。现在,如果您点击其中一个,我的addClass会将.active添加到所有按钮,而不是仅添加一个按钮。除此之外,我无法弄清楚如何将滑块位置与导航菜单相关联。我的意思是,如果用户没有点击任何按钮,我仍然希望按钮显示哪个幻灯片处于活动状态。

我的第二个问题是,无论何时点击按钮,它都会停止幻灯片放映。

我在尝试中做错了什么?

偏离主题,但是现在很难将我现有的内容转换为幻灯片而不是滑动它们吗?



$('.control-button').click(function() {
    button = $(this).attr('id');
    id = button.replace('slide', '');
    pos = (id - 1) * 100;
    $('div#slider figure').css('animation-play-state', 'paused');
    $('div#slider figure').removeClass('figure2');
    $('.control-button').addClass('active');
    posStr = '-' + pos + '%';
    $('.figure').css('left', posStr);
});

$('img').click(function() {
    $('div#inner').css('left', '0px');
    $('div#slider figure').addClass('figure2');
    $('div#slider figure').css('animation-play-state', 'running');

这使所有按钮都处于活动状态:

$('.control-button').addClass('active');

将其替换为:

$('.control-button').removeClass('active');
$(event.target).addClass('active');

event参数添加到该函数中,以便您可以使用event.target

$('.control-button').click(function(event) {

修改

使控制按钮激活&#34;自然&#34;因为图像幻灯片有点难。

让每张图片都有一个属性,说明它是哪张幻灯片:

<figure class="figure figure2">
    <img data-number="slide1" src="https://iso.500px.com/wp-content/uploads/2016/02/stock-photo-139669245.jpg" alt>
    <img data-number="slide2" src="http://i.cbc.ca/1.3376224.1450794847!/fileImage/httpImage/image.jpg_gen/derivatives/4x3_620/tundra-tea-toss.jpg" alt>
    <img data-number="slide3" src="https://static.pexels.com/photos/22804/pexels-photo.jpg" alt>
    <img data-number="slide4" src="https://iso.500px.com/wp-content/uploads/2016/02/stock-photo-139669245.jpg" alt>
</figure>

创建一个系统来检测图像何时进入视图:

window.setInterval(function() {

检测正在显示的图像:

    var activeImage = document.elementFromPoint($(window).width()/2, 10); // The image at the horizontal midpoint of the screen

将相应控制按钮的class设置为active

    $('.control-button').removeClass('active');
    $("#"+$(activeImage).attr("data-number")).addClass('active'); // Sets whichever control button that corresponds to the image under the horizontal midpoint of the screen as active

设置在setInterval

结束时检查的频率
}, /*time interval in miliseconds*/);

答案 1 :(得分:1)

至于添加&#39;活跃&#39;对于所有按钮,你应该替换它:

$('.control-button').addClass('active');

用这个:

$('.control-button').removeClass('active');  //this removes all '.active' first
     $(this).addClass('active');

这里发生的是.control-button点击功能,$(this)代表当前的.control-button元素。

那这个呢?我改进了你的脚本。我拿出了你的CSS动画并用另一个JavaScript动画替换了它。看看吧!

$('.control-button').click(function() {
  clearInterval(setInt);
  $('.control-button').removeClass('active');
  $(this).addClass('active');
  var getIndex = $(this).index('.control-button');
  $('.figure img').hide();
  $('.figure img').eq(getIndex).show();
  setInt = setInterval(slide, 5000);
});

function slide() {
  var getIndex = $('.figure img:visible').index('.figure img');
  $('.control-button').removeClass('active');
  $('.figure img:visible').animate({
    width: 'toggle'
  }, 350);
  getIndex++;
  if ((getIndex) == $('.control-button').length) {
    $('.control-button').eq(0).addClass('active');
    $('.figure img').eq(0).animate({
      width: 'toggle'
    }, 350);
  } else {
    $('.control-button').eq(getIndex).addClass('active');
    $('.figure img').eq(getIndex).animate({
      width: 'toggle'
    }, 350);
  }
};
var setInt = setInterval(slide, 5000);
