<div class="text">Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s with the release of Letraset sheets containing Lorem Ipsum passages, and more recently with desktop publishing software like Aldus PageMaker including versions of Lorem Ipsum.

您好，我有两个问题，首先，如果文本大于 div 大小，如何在右下角显示文本“显示更多”，然后单击它并在弹出窗口中显示所有文本？

Answer 1

可以用JS统计文本中有多少个字符，如果超过了div的数量，则显示“显示更多”按钮。然后，您可以使用 window.open 打开一个弹出窗口。参见 this fiddle
