js虛擬鍵盤代碼_用js怎麼寫一個回車鍵盤事件

『壹』移動web 怎麼捕獲虛擬鍵盤彈出和關閉事件

1、當虛擬鍵盤彈出的時候，window的resize事件會被觸發，問題里的input是使用position:fixed嗎，如果是position: fixed，在resize觸發時應該會自動調整位置吧。

2、以下js可以實現此效果：

var wHeight = windows.innerHeight; //獲取初始可視窗口高度

$(window).resize(function() { //監測窗口大小的變化事件

var hh = windows.innerHeight; //當前可視窗口高度

var viewTop = $(window).scrollTop(); //可視窗口高度頂部距離網頁頂部的距離

if(wHeight > hh){ //可以作為虛擬鍵盤彈出事件碧攜掘

$("body,html").animate({scrollTop:viewTop+100}); //調隱衡整可視頁面的位置

}else{ //可以作為虛擬鍵盤關閉事悔核件

$("body,html").animate({scrollTop:viewTop-100});

}

wHeight = hh;

});

『貳』求js虛擬鍵盤鍵盤

按照apollo47的說法
當你取回來後再轉換一次就好
return orgStr.replaceAll("<br>","\r\n" );

我們再做開發時候一般會做個轉換的工具類
或者使用FCKEditor這種開源的組件
一般採用後者來做網上很多下個拿來就用

『叄』用js怎麼寫一個回車鍵盤事件

document.onkeydown=function(event){

var e = event || window.event || arguments.callee.caller.arguments[0];

if(e && e.keyCode==27){ // 按 Esc

//要做的事情

}

if(e && e.keyCode==113){ // 按 F2

//要做的事情

}

if(e && e.keyCode==13){ // enter 鍵

//要做的事情

}

};

</script>

Js鍵盤事件

keydown：按鍵按下

keyup：按鍵抬起

keypress：按鍵按下抬起

<body>

</body>

/*輸出輸入的字元*/

function myKeyDown(id) {

console.log(document.getElementById(id).value);

}

/*按鍵結束，字體轉換為大寫*/

function myKeyUp(id) {

var text = document.getElementById(id).value;

document.getElementById(id).value = text.toUpperCase();

}

</script>

常用的鍵盤事件對應的鍵碼：

keyCode 8 = BackSpace BackSpace

keyCode 9 = Tab Tab

keyCode 12 = Clear

keyCode 13 = Enter

keyCode 16 = Shift_L

keyCode 17 = Control_L

keyCode 18 = Alt_L

keyCode 19 = Pause

keyCode 20 = Caps_Lock

keyCode 27 = Escape Escape

『伍』想請教一下各位高手虛擬鍵盤應該如何寫。

使用keybd_event函數：
VOID keybd_event(
BYTE bVk, // virtual-key code
BYTE bScan, // hardware scan code
DWORD dwFlags, // flags specifying various function options
DWORD dwExtraInfo // additional data associated with keystroke
);
你是做了很多按鈕，然後響應按鈕按下的消息嗎？如果是這樣的話，就在按鈕按下的消息函數里添加如下的代碼就行了（反正就是添加到你姿襲需要模擬按鍵的那個地方）：
keybd_event(VK_H, 0, 0, 0); // 模卜冊消擬按下H鍵

『陸』 js怎麼聽移動端鍵盤展開事件

方法一實現代碼:

var winHeight = $(window).height();

$(window).resize(function(){

var thisHeight=$(this).height();

if(winHeight - thisHeight >50){

//窗口發生改變(大),故此時鍵盤彈出

//當軟鍵盤彈出，在這裡面操作

}else{

//窗口發生改變(小),故此時鍵盤收起

//當軟鍵盤收起，在此處操作

}

});

方法二:監控鍵盤。

監控的方式其實篩選下來也不過兩種：

① 時鍾setInterval不停監控

② 系統級別的監控，比如鍵盤出現時候通知window一個事件，但是很遺憾現在還沒有這個事件，但是這個事件等於

input類元素獲取焦點 == 彈出虛擬鍵盤

input類元素失去焦點 == 收起虛擬鍵盤

基於系統監控這點，我們還可以監控resize事件或者scroll事件，但是經過我的測試。

setInterval表現比較好.於是，我們簡單寫一段代碼，可靠是否滿足需求：

window.alert = function (msg) {

$('body').append('<div>' + msg + '</div>')

};

function fixedWatch(el) {

if(document.activeElement.nodeName == 'INPUT'){

el.css('position', 'static');

} else {

el.css('position', 'fixed');

}

setInterval(function () {

fixedWatch($('#headerview header'));

}, 500);

『柒』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>

『捌』 js怎麼控制虛擬鍵盤彈出和收起

js 移動端關於頁面布局，如果底部有position:fixed的盒子，又有input，當軟鍵盤彈出收起都會影響頁面布局。這時候可以監聽resize事件，代碼如下，而ios沒有相關事件。
var winHeight = $(window).height(); //獲取當前頁面高度$(window).resize(function(){ var thisHeight=$(this).height(); if(winHeight - thisHeight >50){ //當軟鍵盤彈出，在這裡面操作 }else{ //當軟鍵盤收起，在此處操作 }
});

/**
* 解決ios鍵盤彈出遮擋input
*/
function iosInput() {
if(isIos()){
$('.chart-footer').css('position','absolute');
//解決第三方軟鍵盤喚起時底部input輸入框被遮擋問題
var bfscrolltop = document.body.scrollTop;//獲取軟鍵盤喚起前瀏覽器滾動部分的高度
$(".chart-input").focus(function(){//在這里『input.inputframe』是我的底部輸入欄的輸入框，當它獲取焦點時觸發事件
interval = setInterval(function(){//設置一個計時器，時間設置與軟鍵盤彈出所需時間相近
document.body.scrollTop = document.body.scrollHeight;//獲取焦點後將瀏覽器內所有內容高度賦給瀏覽器滾動部分高度
},100)
}).blur(function(){//設定輸入框失去焦點時的事件
clearInterval(interval);//清除計時器
document.body.scrollTop = bfscrolltop;
//將軟鍵盤喚起前的瀏覽器滾動部分高度重新賦給改變後的高度
});
}
}
iosInput();
