javascript - 是否可以跳入 slider ？

标签 javascript jquery html css slider

是否可以获得特定幻灯片的链接？一旦我在示例中选择了链接， slider 就不再起作用。只显示没有功能的列表项。选择链接时， slider 应滚动到相应的幻灯片。这有可能吗？任何帮助将不胜感激。谢谢。

jQuery(document).ready(function($) {

  $('#checkbox').change(function() {
    setInterval(function() {
      moveRight();
    }, 3000);
  });

  var slideCount = $('#slider ul li').length;
  var slideWidth = $('#slider ul li').width();
  var slideHeight = $('#slider ul li').height();
  var sliderUlWidth = slideCount * slideWidth;

  $('#slider').css({
    width: slideWidth,
    height: slideHeight
  });

  $('#slider ul').css({
    width: sliderUlWidth,
    marginLeft: -slideWidth
  });

  $('#slider ul li:last-child').prependTo('#slider ul');

  function moveLeft() {
    $('#slider ul').animate({
      left: +slideWidth
    }, 200, function() {
      $('#slider ul li:last-child').prependTo('#slider ul');
      $('#slider ul').css('left', '');
    });
  };

  function moveRight() {
    $('#slider ul').animate({
      left: -slideWidth
    }, 200, function() {
      $('#slider ul li:first-child').appendTo('#slider ul');
      $('#slider ul').css('left', '');
    });
  };

  $('a.control_prev').click(function() {
    moveLeft();
  });

  $('a.control_next').click(function() {
    moveRight();
  });

});

最佳答案

你必须在这里做更多的工作 - 所以这就是我所做的:

I. 首先我创建了一个 slideRight 函数，它有一个回调:

function slideRight(callback) {
    $('#slider ul').animate({
      left: -slideWidth
    }, 200, function() {
      $('#slider ul li:first-child').appendTo('#slider ul');
      $('#slider ul').css('left', '');
      callback();
    });
}

II. 使用链接到相应幻灯片的属性 data-peek 修改链接，如下所示:

<a href="#" class="peek" data-peek="one">SLIDE 1</a>

III. 现在下面的脚本将发挥作用:

$('a.peek').click(function() {
    slide($('#slider ul'), $(this).attr('data-peek'));
  });

  function slide(el, peek) {
    if (el.find('li:nth-child(2)').attr('id') !== peek) {
      slideRight(function() {
        slide(el, peek);
      });
    }
  }

请看下面的演示:

jQuery(document).ready(function($) {

  $('#checkbox').change(function() {
    setInterval(function() {
      moveRight();
    }, 3000);
  });

  var slideCount = $('#slider ul li').length;
  var slideWidth = $('#slider ul li').width();
  var slideHeight = $('#slider ul li').height();
  var sliderUlWidth = slideCount * slideWidth;

  $('#slider').css({
    width: slideWidth,
    height: slideHeight
  });

  $('#slider ul').css({
    width: sliderUlWidth,
    marginLeft: -slideWidth
  });

  $('#slider ul li:last-child').prependTo('#slider ul');

  function moveLeft() {
    $('#slider ul').animate({
      left: +slideWidth
    }, 200, function() {
      $('#slider ul li:last-child').prependTo('#slider ul');
      $('#slider ul').css('left', '');
    });
  };


  function moveRight() {
    $('#slider ul').animate({
      left: -slideWidth
    }, 200, function() {
      $('#slider ul li:first-child').appendTo('#slider ul');
      $('#slider ul').css('left', '');
    });
  };

  function slideRight(callback) {
    $('#slider ul').animate({
      left: -slideWidth
    }, 200, function() {
      $('#slider ul li:first-child').appendTo('#slider ul');
      $('#slider ul').css('left', '');
      callback();
    });
  }

  $('a.control_prev').click(function() {
    moveLeft();
  });

  $('a.control_next').click(function() {
    moveRight();
  });

  $('a.peek').click(function() {
    slide($('#slider ul'), $(this).attr('data-peek'));
  });

  function slide(el, peek) {
    if (el.find('li:nth-child(2)').attr('id') !== peek) {
      slideRight(function() {
        slide(el, peek);
      });
    }
  }

});

编辑:

这是一个不使用自定义属性的解决方案——使用 id 代替:

jQuery(document).ready(function($) {

  $('#checkbox').change(function() {
    setInterval(function() {
      moveRight();
    }, 3000);
  });

  var slideCount = $('#slider ul li').length;
  var slideWidth = $('#slider ul li').width();
  var slideHeight = $('#slider ul li').height();
  var sliderUlWidth = slideCount * slideWidth;

  $('#slider').css({
    width: slideWidth,
    height: slideHeight
  });

  $('#slider ul').css({
    width: sliderUlWidth,
    marginLeft: -slideWidth
  });

  $('#slider ul li:last-child').prependTo('#slider ul');

  function moveLeft() {
    $('#slider ul').animate({
      left: +slideWidth
    }, 200, function() {
      $('#slider ul li:last-child').prependTo('#slider ul');
      $('#slider ul').css('left', '');
    });
  };


  function moveRight() {
    $('#slider ul').animate({
      left: -slideWidth
    }, 200, function() {
      $('#slider ul li:first-child').appendTo('#slider ul');
      $('#slider ul').css('left', '');
    });
  };

  function slideRight(callback) {
    $('#slider ul').animate({
      left: -slideWidth
    }, 200, function() {
      $('#slider ul li:first-child').appendTo('#slider ul');
      $('#slider ul').css('left', '');
      callback();
    });
  }

  $('a.control_prev').click(function() {
    moveLeft();
  });

  $('a.control_next').click(function() {
    moveRight();
  });

  $('a.peek').click(function() {
    slide($('#slider ul'), $(this).attr('id').split('_')[1]);
  });

  function slide(el, peek) {
    if (el.find('li:nth-child(2)').attr('id') !== peek) {
      slideRight(function() {
        slide(el, peek);
      });
    }
  }
