js監聽鍵盤回車_用js怎麼寫一個回車鍵盤事件

Ⅰ js監聽回車鍵觸發了方法，但是可以不換行么，求高手

<html>
<head>
<scriptsrc="jquery-1.6.4.min.js"></script>
<script>
functionback(event){
event=event||window.event;
if(event.keyCode==13){
event.returnValue=false;
returnfalse;
}
}
</script>
</head>
<body>
<textarearows="3"cols="40"id="te"onkeypress="back(event);"></textarea>
<textarearows="3"cols="40"id="te1"></textarea>
</body>
</html>

Ⅱ 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

Ⅲ JS 鍵盤回車和滑鼠單擊事件合並

一個是鍵盤事件，一個是mouse 事件！
是不可以合並的!
不就是執行重復的么？
重新定義專個函數啊屬！repeat=function(){$('#single_slide_show_wrapper').addClass('slideshow_already_start');
$("video").prop('muted', true); // if is home page
$('.slider_wrapper').unslider({
speed: 500,
// The speed to animate each slide (in milliseconds)
delay: false,
arrows: true,
fluid: true,
keys: true,
dots: true,

complete: function() {}}
直接調用就可以了呀！

Ⅳ 怎麼在JS中增加鍵盤監聽

鍵盤的每個鍵都有對應的事件值，用按鍵按下或抬起事件，就可以綁定了，事件和對應值如下：
1、keydown()
keydown事件會在鍵盤按下時觸發.
2、keyup()
keyup事件會在按鍵釋放時觸發,也就是你按下鍵盤起來後的事件
3、keypress()
keypress事件會在敲擊按鍵時觸發,我們可以理解為按下並抬起同一個按鍵

對應值：
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

Ⅳ JS如何獲取用戶輸入的回車，空格等特殊字元

document.onkeydown=function(e){console.log(e.keyCode)}

監聽鍵盤事抄件，回車是13，空格襲是32；

你可以復制上面的代碼，按F12 粘貼進控制台，按鍵盤就可以看到每個鍵對應的code

Ⅵ JavaScript中如何捕獲一個鍵盤輸入，如當按回車後，焦點移動到下一個元素

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>焦點事件</title>
</head>
<script type="text/javascript">

function change(){
if(window.event.keyCode==13){
var text = document.getElementById("2");
text.focus();
}
}
function init(){
var text = document.getElementById("1");
text.focus();
}
</script>
<body onload="init();">
<input type="text" id="1" onkeydown="javascript:change();"/>
<input type="text" id="2"/>

</body>
</html>

Ⅶ 如何在交互中捕捉鍵盤回車事件

按下回車鍵執行事件需要使用監聽鍵盤按鍵來實現，然後就和普通的事件綁定一樣寫處理事件函數即可。工具原料：編輯器、瀏覽器 1、實現一個按鍵事件，按下回車鍵觸發一個處理函數

Ⅷ 用js怎麼寫一個回車鍵盤事件

Ⅸ react js 怎樣綁定鍵盤敲擊回車事件

class Demo extends Components{

componentDidMount(){

document.addEventListener("keydown",this.handleEnterKey);

}

componentWillUmount(){

document.removeEventListener("keydown",this.handleEenterKey);

}

handleEnterKey = (e) => {

if(e.keyCode === 13){

//do somethings

}

render(){

}

擴展抄資料

React獲取表單值襲

1、監聽表單的改變事件 onChange

2、在改變的事件里獲取表單輸入的值通過事件對象獲取值 e.target.value

3、把表單輸入的值賦值給username this.setState({})

4、點擊按鈕的時候獲取state裡面的username this.state.username

Ⅹ 關於js中事件監聽的問題（文本框回車鍵失去焦點）

你可以在輸入框裡面一個js事件onkeydown=「document.getElementById('確定按鈕的Id').focus()」
如果還不行把你的代碼貼出來我看下
