js监听键盘回车_用js怎么写一个回车键盘事件

Ⅰ js监听回车键触发了方法，但是可以不换行么，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怎么写一个回车键盘事件

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 键

//要做的事情

}

};

</script>

Js键盘事件

keydown：按键按下

keyup：按键抬起

keypress：按键按下抬起

<body>

</body>

/*输出输入的字符*/

function myKeyDown(id) {

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

}

/*按键结束，字体转换为大写*/

function myKeyUp(id) {

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

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

}

</script>

常用的键盘事件对应的键码：

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 键盘回车和鼠标单击事件合并

一个是键盘事件，一个是mouse 事件！
是不可以合并的!
不就是执行重复的么？
重新定义专个函数啊属！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() {}}
直接调用就可以了呀！

Ⅳ 怎么在JS中增加键盘监听

键盘的每个键都有对应的事件值，用按键按下或抬起事件，就可以绑定了，事件和对应值如下：
1、keydown()
keydown事件会在键盘按下时触发.
2、keyup()
keyup事件会在按键释放时触发,也就是你按下键盘起来后的事件
3、keypress()
keypress事件会在敲击按键时触发,我们可以理解为按下并抬起同一个按键

对应值：
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
keycode 19 = Pause
keycode 20 = Caps_Lock
keycode 27 = Escape Escape

Ⅳ JS如何获取用户输入的回车，空格等特殊字符

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

监听键盘事抄件，回车是13，空格袭是32；

你可以复制上面的代码，按F12 粘贴进控制台，按键盘就可以看到每个键对应的code

Ⅵ JavaScript中如何捕获一个键盘输入，如当按回车后，焦点移动到下一个元素

<!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>焦点事件</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 如何在交互中捕捉键盘回车事件

按下回车键执行事件需要使用监听键盘按键来实现，然后就和普通的事件绑定一样写处理事件函数即可。工具原料：编辑器、浏览器 1、实现一个按键事件，按下回车键触发一个处理函数

Ⅷ 用js怎么写一个回车键盘事件

Ⅸ react js 怎样绑定键盘敲击回车事件

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(){

}

扩展抄资料

React获取表单值袭

1、监听表单的改变事件 onChange

2、在改变的事件里获取表单输入的值通过事件对象获取值 e.target.value

3、把表单输入的值赋值给username this.setState({})

4、点击按钮的时候获取state里面的username this.state.username

Ⅹ 关于js中事件监听的问题（文本框回车键失去焦点）

你可以在输入框里面一个js事件onkeydown=“document.getElementById('确定按钮的Id').focus()”
如果还不行把你的代码贴出来我看下
