要自动选择面板(例如自动 slider /图片库)，您需要假点击每个选项卡(药丸)链接。

基础是:

• 在标记中添加一些内容，表明这是一个“选项卡 slider ”。在本例中，是一个data- 属性。
• 循环集合并实例化每个选项卡 slider 。对于每个选项卡 slider :
  • 获取每个选项卡的引用。
  • 计数选项卡 - 与模运算符 (%1) 和增量变量一起使用以确定要显示的面板。
  • 创建一个可以重复调用的函数 setTimeout，它将通过触发选项卡上的点击事件前进到下一个面板。

$( '[data-widget="tab-slider"]' ).each( function ( i, el ) {

  const $container   = $( this );
  const $sliderLinks = $container.find( '.nav-link' );
  const panelCount   = $sliderLinks.length;
  const delay        = 3000; // milleseconds
  let   index        = 0;

  function nextTabSliderPanel() {

    $sliderLinks.eq( index++ % panelCount ).trigger( 'click' );
    setTimeout( nextTabSliderPanel, delay );

  }
  
  nextTabSliderPanel(); // Start the slider.

} );
