再发一个WM_KEYUP

C# 模拟按键库，支持模拟窗口按键 InitSuperKeys() 安装WINIO驱动，一般用于Form_Load事件中调用 CloseSuperKeys() 卸载WINIO驱动，一般用于Form_Closed事件中调用 KeyDown(Key) 模拟普通Key键按下。 KeyDownEx(Key)模拟扩展Key键按下。 KeyUp(Key)模拟普通Key键弹起。 KeyUpEx(Key)模拟扩展Key键弹起。 KeyPress(Key)模拟普通Key键按下并弹起一次。其中按下和弹起的默认时间间隔是200毫秒 KeyPress(Key,Int32)模拟普通Key键按下并弹起一次。其中按下和弹起的时间间隔是第二个参数，单位为毫秒。 KeyPressEx(Key)模拟扩展按键Key按下并弹起一次。其中按下和弹起的默认时间间隔是200毫秒，写入扩展按键信息间隔时间为100毫秒 KeyPressEx(Key,Int32)模拟扩展按键Key按下并弹起一次。其中按下和弹起的时间间隔是第二个参数，单位为毫秒，写入扩展按键信息间隔时间为100毫秒。 KeyPressEx(Key,Int32,Int32)模拟扩展按键Key按下并弹起一次。其中按下和弹起的时间间隔是第二个参数，单位为毫秒，写入扩展按键信息间隔时间是第三个参数，单位为毫秒。

计数按键只是通过计算事件对模块进行简单测试。

jQuery 事件 jQuery 是为事件处理特别设计的。什么是事件？页面对不同访问者的响应叫做事件。事件处理程序指的是当 HTML 中发生某些事件时所调用的方法。实例：在元素上移动鼠标。选取单选按钮点击元素在事件中经常使用术语”触发”（或”激发”）例如： “当您按下按键时触发 keypress 事件”。常见 DOM 事件：鼠标事件键盘事件表单事件文档/窗口事件 dblclick() 当双击元素时，会发生 dblclick 事件。 dblclick() 方法触发 dblclick 事件，或规定当发生 dblclick 事件时运行的函数：实例

JavaScript+jQuery网页特效设计 jQuery事件基础 1、jQuery事件概述 jQuery对JavaScript操作DOM事件进行了封装，形成了更好的事件处理机制；包括常用事件、事件绑定与解绑等。jQuery事件处理方法是jQuery的核心函数。常用事件方法（教材P263表A-4）：分类事件方法描述鼠标 click() 单机鼠标左键时触发 dbclick() 双击鼠标左键时触发键盘 keypress() 键盘按键(Shift、CapsLock等非字符键除外)被按下时触发 keydown() 键盘按键被按下时触发焦点 keyup() 键盘按键被松开时触发 onfocus() 获取焦点时触发 onblur() 失去焦点时触发改变 change() 元素的值发生改变时触发其它 submit() 当表单提交时触发 select() 当文本框(包括和

中的文本被选中的时触<em>发</em>)
scroll()
当滚动条<em>发</em>生变化时触<em>发</em>
resize()
当调整浏览器<em>窗口</em>大小时触<em>发</em>
2、事件的绑定
bind() 方法：可以向被选元素添加一个或多</a></div><div data-report-view="{"mod":"popu_645","index":"5","dest":"https://download.csdn.net/download/weixin_38675797/13632089","strategy":"2~default~OPENSEARCH~Rate","extra":"{\"utm_medium\":\"distribute.pc_relevant_bbs_down_v2.none-task-download-2~default~OPENSEARCH~Rate-5-13632089-bbs-5784.264^v3^pc_relevant_bbs_down_v2_default\",\"dist_request_id\":\"1714132924607_61426\"}","spm":"1035.2023.3001.6557"}" class="list-item" data-v-ca2d15ac><div class="recommend-title" data-v-ca2d15ac><img src="data:image/png;base64,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" alt data-v-ca2d15ac> <a target="_blank" href="https://download.csdn.net/download/weixin_38675797/13632089" data-report-click="{"mod":"popu_645","index":"5","dest":"https://download.csdn.net/download/weixin_38675797/13632089","strategy":"2~default~OPENSEARCH~Rate","extra":"{\"utm_medium\":\"distribute.pc_relevant_bbs_down_v2.none-task-download-2~default~OPENSEARCH~Rate-5-13632089-bbs-5784.264^v3^pc_relevant_bbs_down_v2_default\",\"dist_request_id\":\"1714132924607_61426\"}","spm":"1035.2023.3001.6557"}" data-report-query="spm=1035.2023.3001.6557&utm_medium=distribute.pc_relevant_bbs_down_v2.none-task-download-2~default~OPENSEARCH~Rate-5-13632089-bbs-5784.264^v3^pc_relevant_bbs_down_v2_default&depth_1-utm_source=distribute.pc_relevant_bbs_down_v2.none-task-download-2~default~OPENSEARCH~Rate-5-13632089-bbs-5784.264^v3^pc_relevant_bbs_down_v2_default" class="title" data-v-ca2d15ac>Jquery 监视<em>按键</em>，按下回车键触<em>发</em>某方法的实现代码</a></div> <a target="_blank" href="https://download.csdn.net/download/weixin_38675797/13632089" data-report-click="{"mod":"popu_645","index":"5","dest":"https://download.csdn.net/download/weixin_38675797/13632089","strategy":"2~default~OPENSEARCH~Rate","extra":"{\"utm_medium\":\"distribute.pc_relevant_bbs_down_v2.none-task-download-2~default~OPENSEARCH~Rate-5-13632089-bbs-5784.264^v3^pc_relevant_bbs_down_v2_default\",\"dist_request_id\":\"1714132924607_61426\"}","spm":"1035.2023.3001.6557"}" data-report-query="spm=1035.2023.3001.6557&utm_medium=distribute.pc_relevant_bbs_down_v2.none-task-download-2~default~OPENSEARCH~Rate-5-13632089-bbs-5784.264^v3^pc_relevant_bbs_down_v2_default&depth_1-utm_source=distribute.pc_relevant_bbs_down_v2.none-task-download-2~default~OPENSEARCH~Rate-5-13632089-bbs-5784.264^v3^pc_relevant_bbs_down_v2_default" class="desc" data-v-ca2d15ac>代码如下:[removed]$(function () { $(‘input:text:first’).focus(); //把焦点放在第一个文本框 var $inp = $(‘input’); //所有的input元素$inp.<em>keypress</em>(function (e) { //这里给function一个事件参数命名为e，叫event也行，随意的，e就是IE<em>窗口</em><em>发</em>生的事件。    var key = e.which; //e.which是<em>按键</em>的值    if (key == 13) {        alert(“aaa”);    }}); })</a></div></div></div></div> <div class="public_pc_right_footer2020" style="display:none;" data-v-4a5a7f56></div></div> <div id="right-floor-user-content_562" data-editor="{"type":"floor","pageId":143,"floorId":562}" class="user-right-floor right-box main-box detail-user-right" data-v-229a00b0><div class="__vuescroll" style="height:100%;width:100%;padding:0;position:relative;overflow:hidden;"><div class="__panel __hidebar" style="position:relative;box-sizing:border-box;height:100%;overflow-y:hidden;overflow-x:hidden;transform-origin:;transform:;"><div class="__view" style="position:relative;box-sizing:border-box;min-width:100%;min-height:100%;"><div comp-data="[object Object]" baseInfo="[object Object]" community="[object Object]" class="introduce" data-v-4722a3ae><div class="introduce-title" data-v-4722a3ae><div class="img-info" data-v-4722a3ae><a href="https://bbs.csdn.net/forums/DelphiVCL" class="community-img" data-v-4722a3ae><img src="https://img-community.csdnimg.cn/avatar/0863b3b6b8774fe5b2e8bc593dbf652a.png?x-oss-process=image/resize,m_fixed,h_88,w_88" alt data-v-4722a3ae> <div title="Delphi" class="community-name" data-v-4722a3ae>
