下拉菜单不允许我单击菜单项

Question

我的网站上有一个下拉菜单，除了不能单击链接之外，它都可以正常运行。每当我单击链接（在下拉列表中）时，它只会关闭下拉列表，而不会重定向到页面。我试着玩了一下代码，但是并没有解决它。任何帮助表示赞赏。

jQuery(document).ready(function() {
    // insert toggle button
    jQuery(".advanced-sidebar-nav").each(function() {
        jQuery(".menu-item-has-children", jQuery(this)).each(function() {
            // insert toggle button
            jQuery("> a", jQuery(this)).append(
                '<span class="advanced-sidebar-nav-toggle"></span>'
            );

            // add indent
            var depth = jQuery(this).parents(".menu-item-has-children").length;
            jQuery("ul li a", jQuery(this)).attr(
                "style",
                "padding-left:" + (depth + 2) * 20 + "px !important"
            );

            // open nav menu toggle
            if (jQuery("ul", jQuery(this)).css("display") == "block") {
                jQuery(".advanced-sidebar-nav-toggle", jQuery(this)).addClass(
                    "advanced-sidebar-nav-toggle-open"
                );
            }
        });
    });
    jQuery(".advanced-sidebar-nav").on(
        "click",
        ".dropdown",
        function(e) {
            e.preventDefault();

            
           const self = $(this).find(".advanced-sidebar-nav-toggle");

            jQuery(".advanced-sidebar-nav-menu-open").each(
              function() {
                  $(this).find(".advanced-sidebar-nav-toggle").parent("a").removeClass("advanced-sidebar-nav-menu-open").siblings("ul").slideUp(300);
                  $(this).find(".advanced-sidebar-nav-toggle").not(self).removeClass("advanced-sidebar-nav-toggle-open");
              }
            );

            jQuery(self).toggleClass("advanced-sidebar-nav-toggle-open");

            if(jQuery(self).hasClass("advanced-sidebar-nav-toggle-open")) {
                jQuery(self)
                      .parent("a")
                      .addClass("advanced-sidebar-nav-menu-open")
                      .siblings("ul")
                      .slideDown(300);
                      
                  } else {
                    jQuery(self)
                      .parent("a")
                      .removeClass("advanced-sidebar-nav-menu-open")
                      .siblings("ul")
                      .slideUp(300);
                  }
        }
    );
    
});

Answer 1

请检查此内容。我仅将您的目标点.dropdown更改为.dropdown > a，但我不知道为什么使用非常困难的方法来实现这一目标。

jQuery(document).ready(function() {
    // insert toggle button
    jQuery(".advanced-sidebar-nav").each(function() {
        jQuery(".menu-item-has-children", jQuery(this)).each(function() {
            // insert toggle button
            jQuery("> a", jQuery(this)).append(
                '<span class="advanced-sidebar-nav-toggle"></span>'
            );

            // add indent
            var depth = jQuery(this).parents(".menu-item-has-children").length;
            jQuery("ul li a", jQuery(this)).attr(
                "style",
                "padding-left:" + (depth + 2) * 20 + "px !important"
            );

            // open nav menu toggle
            if (jQuery("ul", jQuery(this)).css("display") == "block") {
                jQuery(".advanced-sidebar-nav-toggle", jQuery(this)).addClass(
                    "advanced-sidebar-nav-toggle-open"
                );
            }
        });
    });
    jQuery(".advanced-sidebar-nav").on(
        "click",
        ".dropdown > a",
        function(e) {
            e.preventDefault();

            
           const self = $(this).find(".advanced-sidebar-nav-toggle");

            jQuery(".advanced-sidebar-nav-menu-open").each(
              function() {
                  $(this).find(".advanced-sidebar-nav-toggle").parent("a").removeClass("advanced-sidebar-nav-menu-open").siblings("ul").slideUp(300);
                  $(this).find(".advanced-sidebar-nav-toggle").not(self).removeClass("advanced-sidebar-nav-toggle-open");
              }
            );

            jQuery(self).toggleClass("advanced-sidebar-nav-toggle-open");

            if(jQuery(self).hasClass("advanced-sidebar-nav-toggle-open")) {
                jQuery(self)
                      .parent("a")
                      .addClass("advanced-sidebar-nav-menu-open")
                      .siblings("ul")
                      .slideDown(300);
                      
                  } else {
                    jQuery(self)
                      .parent("a")
                      .removeClass("advanced-sidebar-nav-menu-open")
                      .siblings("ul")
                      .slideUp(300);
                  }
        }
    );
