Javascript捕获密钥 [英] Javascript capture key

问题描述

我正在尝试使用javascript从textarea中删除回车键。问题是虽然我能够发现按下输入键，但我无法避免它进入textarea。我不希望输入键即\ n显示在文本区域中。

I am trying to catpure the enter key from a textarea using javascript. The problem is that although I am able to find out that the "enter" key was pressed, I am not unable to avoid it from coming in the textarea. I dont want the enter key i.e. "\n" to be displayed in the text area.

有关如何实现这一点的任何建议吗？

Any suggestions on how to achieve that?

谢谢。

推荐答案

尝试将此功能设置为文本区域的onKeyDown事件：

Try setting this function as the onKeyDown event for the text area:

ex： onkeydown =javascript：return fnIgnoreEnter（event）;

function fnIgnoreEnter(thisEvent) {
  if (thisEvent.keyCode == 13) { // enter key
    return false; // do nothing
  }
}
