HTML - JS How to open an image in an image popup by clicking on it?
提问by Alessio
I should write some code in htmlor javascriptor other to open a popup window by clicking on an image.
I have already seen the window.open()method, but this isn't what I am looking for.
Precisely I want to open an image popup like Twitter does: overshadowing the background and displaying the image enlarged in the middle of the screen.
我应该写一些代码html或javascript或其他通过点击图片即可打开一个弹出窗口。我已经看过这个window.open()方法，但这不是我要找的。确切地说，我想像 Twitter 那样打开一个图像弹出窗口：遮蔽背景并在屏幕中间显示放大的图像。
Any suggestions?
有什么建议？

It's really simple to use. Include the script tags and CSS stylesheets in your HTML file, and then simply use:
使用起来真的很简单。在 HTML 文件中包含脚本标签和 CSS 样式表，然后只需使用：

You can use Bootstrap, else, make a DIV with position absolute/fixed and centered. On click get the URL of image and put this inside the new DIV in a img tag. Finally Add a fadeIn/Out to the new DIV for the effect.
您可以使用 Bootstrap，否则，制作一个位置绝对/固定和居中的 DIV。单击获取图像的 URL 并将其放在新 DIV 中的 img 标签中。最后在新的 DIV 中添加淡入/淡出效果。
