IE e.keyCode - How can I differentiate between ampersand and up-arrow?

我怕爱的太早我们不能终老 提交于 2019-12-04 10:59:36
问题 I am fighting with a very strange javascript behavior on a jQuery UI widget I'm trying to fix. IE7 (win XP), jQuery 1.2.6 (yes, it's an old version). The widget is a combo-box, which captures keyboard events and has special behaviors for the arrow keys. When I try to type the "&" character into the flexbox input field, I get strange behavior. The flexbox has some code like: //initialization $myInputElement.keypress($.flexbox.process_key); $.flexbox.process_key = function process_key(e) { $

问题 I would like to call power off,reboot, etc.. dialog as same as default android dialog when push power button long from my application. I no need to call directly reboot,power off, etc... from my application. Just would like to call that dialog. How to call it ? or How to send power button key on application ? Thanks in advance. 回答1: If you look at the source code, you'll see it's handled internally (PhoneWindowManager.java and GlobalActions.java). There is no interface whatsoever through the

Send key code to command line program on OS X

问题 I want to make a script that starts a program and then sends it key input. In psuedo-script: #!/bin/bash ./program << (PRESS CONTROL-Z) The program is running so if there were additional commands in the script they will not be reached unless say control-z terminates the program. Is this possible? From what I've found I thought it might require key codes but I could be wrong. 回答1: You might be looking for expect (from http://expect.nist.gov/). This deals with the complexities of pseudo-ttys

使用JS监听键盘按下事件(keydown event)

1、监听全局键盘按下事件,例如监听全局回车事件 $(document).keydown(function(event){ if(event.keyCode == 13){ alert('你按下了Enter'); } }); 2、监听某个组件键盘按下事件,例如监听id为btn的button组件的回车按下事件 $("#btn").keydown(function(event){ if(event.keyCode==13){ alert('你按下了Enter'); } }); 3、如果是要监听组合键,例如监听ctrl+c $(document).keyup(function(event){   if(event.ctrlKey && event.keyCode==67){     alert('你按下了CTRL+C')   } }); 4、详细keyCode值列表 原文链接: https://www.cnblogs.com/pangpanghuan/p/6423204.html 来源: https://www.cnblogs.com/gyt79082/p/11810336.html

UGUI 实现屏幕方向输入

北战南征 提交于 2019-12-03 10:27:13
在Unity中实现屏幕输入方向(例如摇杆),一般会用到 Input 类来获取触摸点的屏幕位置,然后根据触摸点的位置变动,计算出输入方向。 但是会存在一个问题,如果游戏界面中有按钮,对按钮的点击事件,也会影响到Input 的触摸点输入,我们希望能避免这个问题。 一个比较好的实现方案就是,不使用Input,而是使用UGUI的触摸事件。 这个方案比较简单,新建一个DirectionInput 继承MonoBehaviour,并且继承IPointerDownHandler,IPointerUpHandler,IDragHandler 三个接口。然后在代码中实现 OnPointerDown,OnDrag,OnPointerUp三个方法。 具体代码如下,可以在其他模块中,读取该对象的direction字段来获取方向。 using UnityEngine; using UnityEngine.EventSystems; /// <summary> /// 玩家屏幕方向输入 /// </summary> public class DirectionInput : MonoBehaviour ,IPointerDownHandler,IPointerUpHandler,IDragHandler { private const float MIN_MOVE_DISTANCE = 30f; public
