codemirror autocomplete after any keyup?

问题 I'm working on trying to add a custom autocomplete, that I want to trigger whenever the user is typing (configurable of course). I've found a couple examples of autocomplete for codemirror: http://codemirror.net/demo/complete.html and http://codemirror.net/demo/xmlcomplete.html But both of these trigger on specific keys (Control-Space for one and '<' for the other) and both use the extraKeys functionality to process the events, but I want to trigger from any key. I have tried the following:

余生颓废 提交于 2019-12-01 21:42:49
My following code for checking whether Capslock is on or not works fine on "onkeypress" event. But i want it for "onfocus" event. i tried replacing "onkeypress" with "onfocus" for the control,but it doesnt work for me. Any help? (either in javascript or Jquery) <script type="text/javascript" language="Javascript"> function capLock(e) { kc = e.keyCode ? e.keyCode : e.which; sk = e.shiftKey ? e.shiftKey : ((kc == 16) ? true : false); if (((kc >= 65 && kc <= 90) && !sk) || ((kc >= 97 && kc <= 122) && sk)) document.getElementById('divMayus').style.visibility = 'visible'; else document

How to make TextBox to receive only number key values using KeyDown Event in C#?

本秂侑毒 提交于 2019-12-01 12:31:28
This code in my form updates the textBox1.Text twice whenever number keys are pressed. private void textBox1_KeyDown( object sender, KeyEventArgs e ) { //MessageBox.Show(); if( char.IsNumber((char)e.KeyCode) ) { textBox1.Text += (char)e.KeyCode; } } Explain why if you can? Modify the code or provide me a better solution for this. Input ( in textbox1 ): 54321 Output: 1234554321 When you press a key, a character is already appended to your TextBox . Then you run the following code and, if the key represents a number, you append it again: if (char.IsNumber((char)e.KeyCode)) { textBox1.Text +=

Javascript - simulate key events on Chrome 53

问题 I am trying to simulate key event (press) on Chrome 53 . All the solutions that I found on StackOverflow seems not to be working.. My goal is to have a function that gets a keyCode and simulates a key press with it - Pure JS is required function keyPressSimulate(keyCode) {...?} Code samples that I already tried: Node.prototype.fire=function(type,options){ var event=new CustomEvent(type); for(var p in options){ event[p]=options[p]; } this.dispatchEvent(event); } document.fire("keyup",{ctrlKey

How do you remove the Ctrl+C action on a JFileChooser?

China☆狼群 提交于 2019-11-29 13:38:07
I'm embedding a JFileChooser in my program in my own frame with other custom components in the frame. Here's a design of my app as it may help visualize my issues: If you can't tell, the lists directly under the JFrame titles are JFileChoosers . The way this is supposed to work is you assign shortcuts to destinations and then when you press those shortcut keys, the selected file moves to the destination. My strategy for doing this is to assign the shortcut to a javax.swing.JComponent.WHEN_IN_FOCUSED_WINDOW scope of the InputMap of the entire frame. But what's annoying is that something (I

Use keyPressEvent to catch enter or return

*爱你&永不变心* 提交于 2019-11-29 04:34:47
I have a simple form with some combos, labels, buttons and a QTextEdit. I try to catch the enter or return key with keyPressEvent, but for some reason I'm not able to. The ESC key however, that I also use, is recognized. Here's a piece of the code: def keyPressEvent(self, e): print e.key() if e.key() == QtCore.Qt.Key_Return: self.created.setText('return') if e.key() == QtCore.Qt.Key_Enter: self.created.setText('enter') if e.key() == QtCore.Qt.Key_Escape: self.cmbEdit = not(self.cmbEdit) if self.cmbEdit: etc... Am I missing something? It's not completely clear from your code, but it looks like
