是否有替代方法来模拟锚 Link/Target 伪 Class 的行为?
Is There an Alternative Method to Mimic the Behavior of an Anchor Link/Target Pseudo-Class?
原文Post:
onclick
在 <a>
标签中是否可以像 href
一样调用锚点 link?
在下面的代码片段中,我将 <a href="#view">
应用于所有图像,并且 <a id="close-customlightbox" class="lb-animate" href="#!">
作为 return URL 一旦每个图像从灯箱视图中关闭。
理想情况下,我宁愿让锚点提示它们不会为页面的 URL.
创建任何类型的扩展
所以在点击 <a href="#view">
之后,它会像这样添加到页面的 URL 中:
http://ARANDOMURL.com/page#view
然后一旦灯箱 window 关闭,URL 就会显示:
http://ARANDOMURL.com/page#!
然后您必须再点击浏览器的后退按钮很多次才能return到实际的上一页...
关于如何实现这一点有什么建议吗?

感谢 NetMage 的回答,现在可以使用了 :
$('.pic > img').click(function() {
var srcToCopy = $(this).attr('src');
$('body').find('.imgsrc').attr('src', srcToCopy);
$('body').addClass('no-scroll');
$('#view').addClass("target");

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 URL,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 class target
会添加到 #view
元素,这会导致它出现,当您单击关闭框,target
class 被删除,它们消失了。
您不再需要更改 URL 或 href
