显示段落的第一行 [英] Show first line of a paragraph

问题描述

我有一个多行段落的DIV。

I have a DIV with a multi-line paragraph.

有任何方式（可能使用jQuery）只显示段落的第一行，其他？

Is there any way (maybe using jQuery) to only show the first line of the paragraph and hide the others?

推荐答案

没有一个明确的方法来指定第一行。建议改变DIV的高度使用CSS只显示第一行。在我看来，它是最简单的解决方案。如果你随后要更改为使用javascript显示整行，只需使用它将DIV的高度更改回100％即可。

There is not an outright way to do this by specifying the first line. I would suggest changing the height of the DIV using CSS to only show the first line. It would seem to me to be the simplest solution. If you then want to change to show the whole line with javascript just use it to change the height of the DIV back to 100%.

EDIT ：我立即纠正，我不知道有一个一线伪类。但是更改高度可能仍是最简单的方法。

EDIT: I stand corrected, I was not aware that there was a first-line pseudo class. However changing the height may still be the simplest way.
