是否存在模仿锚链/目标伪类的行为的替代方法?

标签: jquery html onclick anchor href

原帖:

onclick标记中的<a>是否可以调用锚链接,就像href那样?

在下面的代码段中,我将<a href="#view">应用于所有图片,并在从灯箱视图关闭每个图片后将<a id="close-customlightbox" class="lb-animate" href="#!">作为返回网址。

理想情况下,我宁愿提示锚点,他们不会在页面的网址上创建任何类型的扩展名。

因此,点击<a href="#view">后,它会添加到网页的网址中,如下所示:

http://ARANDOMURL.com/page#view

然后,一旦灯箱窗口关闭,网址就会显示:

http://ARANDOMURL.com/page#!

然后你需要多次点击浏览器的后退按钮才能返回实际的上一页...

有关如何实现这一目标的任何建议吗?

查看您的示例,您似乎正在使用CSS :target选择器来处理显示和隐藏灯箱。 :target选择器应用于当前URL的目标元素,因此如果您不修改URL,更改不会生效。

不要修改网址,而是将CSS中的所有:target选择器更改为.target选择器。

然后,在您的事件处理程序中:

$('.pic > img').click(function() {
    var srcToCopy = $(this).attr('src');
    $('body').find('.imgsrc').attr('src', srcToCopy);
    $('body').addClass('no-scroll');
    $('#view').addClass("target");
});

$('#customlightbox-controls').on('click', function() {
    $('body').removeClass('no-scroll');
    $('#view').removeClass("target");
});

现在,当您单击图像时,CSS样式类target将添加到#view元素,这会导致它出现,当您单击“关闭”框时,{{1} } class被删除,它们就会消失。

您不再需要更改网址或target,因此您可以移除href的锚标记,然后关闭onclick以重新设置为#view

示例新灯箱实例:

#!

更改为关闭灯箱控件:
