Ⅰ 怎樣用js模擬鍵盤事件

主動觸發事件是一個經常會用到的技巧，它很重要。它和事件綁定一樣存在著瀏覽器兼容性問題。傳統瀏覽器（IE8-）使用createEventObject來創建事件對象，用fireEvent這個方法來觸發事件；現代瀏覽器用createEvent來創建對象，用dspatchEvent來觸發事件。

//獲取瀏覽器版本
var isIE=navigator.userAgent.match(/MSIE (;d)/i);
isIE=isIE?isIE[1]:undefined;

//事件函數
function onclick(e){
e=eevent;
alert(e.msg表醬紫啦，人家羞澀啦～);
};

//給document綁定一個點擊事件
isIElt;9
//傳統瀏覽器使用attachEvent
?document.attachEvent(onclick,onclick)
//現代瀏覽器使用addEventListner
:document.addEventListener(click,onclick,false);

//觸發自定義事件
if(isIElt;9){
//傳統瀏覽器
//創建對象
var event=document.createEventObject();
//給事件對象添加屬性
event.msg=我是fireEvent觸發的;
//觸發事件
document.fireEvent(onclick,event);
}else{
//現代瀏覽器
//創建事件對象
var e=document.createEvent(MouseEvents);
//初始化事件對象
e.initMouseEvent(click),
//給事件對象添加屬性
e.msg=我是despatchEvent觸發的;
//觸發事件
document.dispatchEvent(e);
};

Ⅱ 如何用js輸出鍵盤按鍵

<input type="button" name="btn" value="點擊101"
onclick=" cal(prompt('請輸入第一個鍵盤按鍵字母：'),prompt('請輸入第二個鍵盤按鍵字母：')) " />
<script type="text/javascript">
function cal(num01,num02){
/*var num11 = parseInt(num01);
var num22 = parseInt(num02);*/
alert(num01);
alert(num02);
}
</script>

Ⅲ 求鍵盤的所有按鍵對應的JS函數~~~！！！！或者提供網頁鍵盤源代碼！！

$(window).keydown(function(event){
switch(event.keyCode) {
// ...
// 不同的按鍵可以做不同的事情
// 不同的瀏覽器的keycode不同
// 更多詳細信息: http://unixpapa.com/js/key.html
// ...
}
});

Ⅳ js能模擬鍵盤輸入么

我跟你一樣。有的網頁可以用data數據：way.set("name","用戶名")，其中格式是data-way-name
有的沒有data這下就麻煩了，應該是在按鍵事件裡面沒有執行標記，導致提交函數檢查到沒有執行按鍵事件，建議每個input獲取到焦點，自動填入數據，再發送個按鍵事件。

Ⅳ 如何使用JavaScript調用系統的軟鍵盤

<html>
<body>
<input type="text" id="tt" />
<script language="javascript" type="text/javascript">
document.getElementById('tt').onfocus = function(){
var shell = new ActiveXObject("wscript.shell");
shell.run("osk.exe");
}
</script>
</body>
</html>
我知道：
這個只能在IE瀏覽器實現,而且需要設定IE的安全級別,允許瀏覽器載入ActiveXObject控制項，如圖。
如果不用系統自帶的軟鍵盤，可以用js實現。網上找到一個js寫的。你可以看看

Ⅵ js若何才能模擬鍵盤按鍵

document.onkeydown=function(e){
var e=e|| event;
if(e.ctrlKey && e.keyCode==83){ e.preventDefault(); //阻止默認行為
alert(String.fromCharCode(e.keyCode));}
/*else{alert(e.keyCode)}//這句去掉,看鍵盤的ASCII碼再用*/
}//為document綁定keydown事件

一、設計思路：設計一個簡單的輸入對話框，然後按下enter進行輸入事件。

二、聊天輸入框的代碼如下：

Ⅷ js如何才能模擬鍵盤按鍵

這個不能把，我要是能的話不斷模擬用戶點擊 alt+F4，那網頁還能打開嗎有安全漏洞的東西，瀏覽器一般不會允許
