jQuery不断扩大和缩小的textarea [英] Jquery growing and shrinking textarea

问题描述

当您按Enter键时，我试图使文本区域增大，当您删除行时，请收缩文本区域.换句话说，在编辑文本时，文本区域的大小足以容纳其中的文本.

I'm trying to make a textarea grow when you press enter and shrink when you finish deleting a line. In other words, the textarea remains just big enough to contain the text inside of it, while the text is being edited.

除非有人知道更好的方法，否则现在我正在使用jquery检测按键.在Enter印刷机上使文本区域变大是相当容易的，但是当您删除回车符时，如何缩小文本区域我是茫然的.

Unless anyone knows a better way to do this, right now I'm doing it with jquery detecting keypresses. It's fairly easy to make the textarea larger on an enter press, but I'm at a loss as to how to make it shrink when you delete a carriage return.

您(最好是使用jquery)如何检测何时在文本区域中删除回车符?

How do you (preferably with jquery) detect when a carriage return is deleted in a textarea?

推荐答案

尝试使用TextArea调整大小插件:

Try the TextArea resizer plugin:
