我目前在网站右侧有2个抽屉/菜单,其中1个用于购物车,1个用于产品快速查看选项。

我已经使用Shopify Timber Framework构建了主题,并且抽屉当前滑动打开(#PageContainer在单击时向左移动以显示抽屉)。

我需要更改JS,以便在单击时z-index发生更改,以便正确调用的抽屉在堆栈中最高。

我对JS不太满意,所以不确定这是否简单吗?

任何帮助将不胜感激!

我的代码如下:

JS:

timber.Drawers = (function () {
var Drawer = function (id, position, options) {
var defaults = {
  close: '.js-drawer-close',
  open: '.js-drawer-open-' + position,
  openClass: 'js-drawer-open',
  dirOpenClass: 'js-drawer-open-' + position
};

this.$nodes = {
  parent: $('body, html'),
  page: $('#PageContainer'),
  moved: $('.is-moved-by-drawer')
};

this.config = $.extend(defaults, options);
this.position = position;

this.$drawer = $('#' + id);

if (!this.$drawer.length) {
  return false;
}

this.drawerIsOpen = false;
this.init();
};

Drawer.prototype.init = function () {
$(this.config.open).on('click', $.proxy(this.open, this));
this.$drawer.find(this.config.close).on('click', $.proxy(this.close, this));
};

Drawer.prototype.open = function (evt) {
// Keep track if drawer was opened from a click, or called by another function
var externalCall = false;

// Prevent following href if link is clicked
if (evt) {
  evt.preventDefault();
} else {
  externalCall = true;
}

// Without this, the drawer opens, the click event bubbles up to $nodes.page
// which closes the drawer.
if (evt && evt.stopPropagation) {
  evt.stopPropagation();
  // save the source of the click, we'll focus to this on close
  this.$activeSource = $(evt.currentTarget);
}

if (this.drawerIsOpen && !externalCall) {
  return this.close();
}

// Add is-transitioning class to moved elements on open so drawer can have
// transition for close animation
this.$nodes.moved.addClass('is-transitioning');
this.$drawer.prepareTransition();

this.$nodes.parent.addClass(this.config.openClass + ' ' + this.config.dirOpenClass);
this.drawerIsOpen = true;

// Run function when draw opens if set
if (this.config.onDrawerOpen && typeof(this.config.onDrawerOpen) == 'function') {
  if (!externalCall) {
    this.config.onDrawerOpen();
  }
}

if (this.$activeSource && this.$activeSource.attr('aria-expanded')) {
  this.$activeSource.attr('aria-expanded', 'true');
}

// Lock scrolling on mobile
this.$nodes.page.on('touchmove.drawer', function () {
  return false;
});

this.$nodes.page.on('click.drawer', $.proxy(function () {
  this.close();
  return false;
}, this));
};

Drawer.prototype.close = function () {
if (!this.drawerIsOpen) { // don't close a closed drawer
  return;
}

// deselect any focused form elements
$(document.activeElement).trigger('blur');

// Ensure closing transition is applied to moved elements, like the nav
this.$nodes.moved.prepareTransition({ disableExisting: true });
this.$drawer.prepareTransition({ disableExisting: true });

this.$nodes.parent.removeClass(this.config.dirOpenClass + ' ' + this.config.openClass);

this.drawerIsOpen = false;

this.$nodes.page.off('.drawer');
};
return Drawer;
})();

最佳答案

给您的两个抽屉一个普通的类,然后查询被单击的文档。
设置两个抽屉的z索引,然后将单击的抽屉的z索引设置为更高!

window.onload = function() {

    [].forEach.call(document.querySelectorAll('.drawers'), function(el) {
        el.addEventListener('click', drawerOpened);
    });

        function drawerOpened()
        {
            $('.drawers').css('z-index', '50');
            $(this).css('z-index', '60');
        }
    )};
