JQuery用标题切换OL列表

Question

我有一个OL列表作为手风琴使用jQuery切换，我还有一个带有锚链接的侧边栏链接到OL列表标题。我想这样做，以便锚链接链接并切换各自的标题。

有人可以帮我添加这个脚本，这样当我点击锚链接时，相应的部分div会打开吗？

谢谢！

jQuery('#sections > li > div').hide();

jQuery('#sections > li > h2').click(function(e){
    
    e.preventDefault();
    // hide all div
    var $li = jQuery(this).parent();
    var $div = jQuery(this).parent().find('div');
    jQuery("#sections > li > div").not($div).hide();
    jQuery("#sections > li").not($li).removeClass('active');
    
    // here is what I want to do
    $div.toggle();
    $li.toggleClass('active');
    
});

Answer 1

您可以使用锚点的href手动触发点击。

$('#sections_list li').click(function(e) {
  e.preventDefault();
  var href = $(this).find('a').attr('href');
  $(href).click();
})

jQuery('#sections > li > div').hide();

jQuery('#sections > li > h2').click(function(e) {

  e.preventDefault();
  // hide all div
  var $li = jQuery(this).parent();
  var $div = jQuery(this).parent().find('div');
  jQuery("#sections > li > div").not($div).hide();
  jQuery("#sections > li").not($li).removeClass('active');

  // here is what I want to do
  $div.toggle();
  $li.toggleClass('active');

});

$('#sections_list li').click(function(e) {
  e.preventDefault();
  var href = $(this).find('a').attr('href');
  $(href).click();
})
