我有一些用鼠标滚轮转换幻灯片的 jquery。我添加了 jquery 滑块，并根据 ui.value 与当前幻灯片索引绑定了单击事件以转换幻灯片。问题是，如果您不快速移动滑块，它可以正常工作，但如果您移动它太快，则幻灯片转换当前索引与 ui.value 不一致。ui.value 是正确的，所以我认为这里的点击事件被跳过了？站点 mixmastercocktails.com，单击主图像以显示幻灯片。关于如何确保点击事件被调用的任何想法？

    $('#slider-vertical').slider({
    orientation: 'vertical',
    range: 'min',
    min: 1,
    max: $('#cards li').length,
    value: 1,
    step: 1,
    slide: function( event, ui ) {
        if(ui.value > current_index)
        {
            next.trigger('click');
        }
        if(ui.value < current_index)
        {
            prev.trigger('click');
        }
    }
});

完整的js文件：

(function($) {
var counter = 1;

var newy = 0;
var width = 475;
var nwidth = 475;
var current_index = 1;

    var newz = counter+1000;

    $(this).css('z-index', newz );
    //$(this).html(newz);

$(document).bind('mousewheel', function(event, delta, deltaX, deltaY)

slide当您单击并跳转滑块时不处理该事件。你应该change改用

$('#slider-vertical').slider({
  orientation: 'vertical',
  range: 'min',
  min: 1,
  max: $('#cards li').length,
  value: 1,
  step: 1,
  change: function( event, ui ) {
    if(ui.value > current_index) {
      var index_change = ui.value - current_index;
      for (var i = 0; i < index_change; i++) {
        next.trigger('click');
      }
    }

    if(ui.value < current_index) {
      var index_change = current_index - ui.value;
      for (var j = 0; j < index_change; j++) {
        prev.trigger('click'); 
      }
    }
  }
});
