javascript - 单击时可折叠的 div 高度问题

Question

我遇到了一个关于可折叠 div 高度的奇怪问题。即使在 div 关闭/折叠后，div 的展开高度仍然存在。请引用下图

Javascript 在点击时将高度添加到 li。作为引用，这里是检查元素部分。

<ul id="og-grid" class="og-grid">

            <li><a target="_blank" href="www.somewebsite.com" data- 
   largesrc="uploadimage/project/sfs.jpg" data-title="Website Redesign of " 
   data-type="WebSite" data-description="Website Redesign "><img 
   src="uploadimage/project/thumb/sfs.jpg" alt="img00"></a></li>

   <li style="**transition: height 350ms ease 0s; height: 719px;**" 
 class="">
   <a href="#/" data-largesrc="uploadimage/project/notouch.jpg" data- 
  title="No Touch" data-type="Mobile Application" data-description="Notouch 
  is a simple but useful app that helps you to lock the screen temporarily 
  to prevent unauthorized clicks or to go to other apps from the current

</ul>

Javascript 部分(我相信)是这样的。

  open: function () {

        setTimeout($.proxy(function () {
            // set the height for the preview and the item
            this.setHeights();
            // scroll to position the preview in the right place
            this.positionPreview();
        }, this), 25);

    },
    close: function () {

        var self = this,
            onEndFn = function () {
                if (support) {
                    $(this).off(transEndEventName);
                }
                self.$item.removeClass('og-expanded');
                self.$previewEl.remove();
            };

        setTimeout($.proxy(function () {

            if (typeof this.$largeImg !== 'undefined') {
                this.$largeImg.fadeOut('fast');
            }
            this.$previewEl.css('height', 0);
            // the current expanded item (might be different from this.$item)
            var $expandedItem = $items.eq(this.expandedIdx);
            $expandedItem.css('height', $expandedItem.data('height')).on(transEndEventName, onEndFn);

            if (!support) {
                onEndFn.call();
            }

        }, this), 25);

        return false;

    },
    calcHeight: function () {

        var heightPreview = winsize.height - this.$item.data('height') - marginExpanded,
            itemHeight = winsize.height;

        if (heightPreview < settings.minHeight) {
            heightPreview = settings.minHeight;
            itemHeight = settings.minHeight + this.$item.data('height') + marginExpanded;
        }

        this.height = heightPreview;
        this.itemHeight = itemHeight;

    },
    setHeights: function () {

        var self = this,
            onEndFn = function () {
                if (support) {
                    self.$item.off(transEndEventName);
                }
                self.$item.addClass('og-expanded');
            };

        this.calcHeight();
        this.$previewEl.css('height', this.height);
        this.$item.css('height', this.itemHeight).on(transEndEventName, onEndFn);

        if (!support) {
            onEndFn.call();
        }

    },
    positionPreview: function () {

        // scroll page
        // case 1 : preview height + item height fits in window´s height
        // case 2 : preview height + item height does not fit in window´s height and preview height is smaller than window´s height
        // case 3 : preview height + item height does not fit in window´s height and preview height is bigger than window´s height
        var position = this.$item.data('offsetTop'),
            previewOffsetT = this.$previewEl.offset().top - scrollExtra,
            scrollVal = this.height + this.$item.data('height') + marginExpanded <= winsize.height ? position : this.height < winsize.height ? previewOffsetT - (winsize.height - this.height) : previewOffsetT;

        $body.animate({ scrollTop: scrollVal }, settings.speed);

    },
    setTransition: function () {
        this.$previewEl.css('transition', 'height ' + settings.speed + 'ms ' + settings.easing);
        this.$item.css('transition', 'height ' + settings.speed + 'ms ' + settings.easing);
    },
    getEl: function () {
        return this.$previewEl;
    }
}

return {
    init: init,
    addItems: addItems
};

})();

请指教，如何解决这个问题。 (有没有CSS或者Javascript方式)

Answer 1

尝试在动画结束时执行命令 javascript:在包含打开图像的容器上删除 ()，或清空 ()。如果在尝试这些命令后您仍然看到错误的高度，这意味着您已经在容器上应用了宽度/高度属性，因此您必须删除它们，将它们的值更改为 ''。

编辑:

close: function () {
    ....
    setTimeout($.proxy(function () {            
        document.getElementsByClassName('og-expander')[0].parentElement.removeAttribute("style");
        if (typeof this.$largeImg !== 'undefined') {
    ....

我已经测试过，它有效。
