To emulate the pressing of a button on the ENTER key, use the following code. The code can be seen in action in the Live Demo and produces the following Output when text is entered and the ENTER key is pressed in the input field. The Example uses the keypress() event to trigger the...
enterPressed(event) { var code = event.keyCode || event.which; if(code === 13) { //13 is the enter keycode //Do stuff in here } } 所以它所做的是向输入元素添加一个事件侦听器。请参阅 React 的键盘事件。函数 enterPressed 然后在事件上触发,现在 enterPressed 检测键码,如果是13,做一些...
You will need to listen for the ENTER key press event. Take a look at Enter key press event in JavaScript for some examples on how it is done. Share Improve this answer Follow edited May 23, 2017 at 10:31 CommunityBot 111 silver badge answered Jan 17, 2012 at 12:04 moranjk 15111...

我正在使用PyQt5和Qt Designer中的QTableWidget来创建数据输入表。我想要的是一种简单的方法,让“回车”keyPressEvent在表格中移动,就像按下Tab键一样。下面的代码捕获Enter键按下事件。我如何让它移动光标?def keyPressEvent(self, ev): if ev.key() in (QtCore.Qt.Key_Return, QtCore.Qt.Key_EnterOpti...
You need to register it with keypress event. It should work after that. On my system it's working. 複製 $(document).keypress(function(event){ var keycode = (event.keyCode ? event.keyCode : event.which); if(keycode == '13'){ alert('You pressed a "enter" key in somewhere'); }...
if (e.KeyChar == (char)Keys.Enter) { SendKeys.Send("{tab}"); } } 二、手动置下一个需要获取焦点的文本框 如果想让焦点跳到任意文本框或者其他地方, 在文本框的键盘按下事件中,将焦点放到目标文本框上。 private void textBox1_KeyPress(object sender, KeyPressEventArgs e) ...
