本文實(shí)例總結(jié)了javascript實(shí)現(xiàn)回車(chē)鍵提交表單方法。分享給大家供大家參考。具體分析如下：
第一種方法：javascript實(shí)現(xiàn)
復(fù)制代碼代碼如下:
<html>
<head>
<title> javascript 實(shí)現(xiàn)回車(chē)鍵提交表單</title>
<meta http-equiv="content-type" content="text/html;charset=utf-8" />
<script type="text/javascript">
document.onkeydown = function(ev){
ev = ev || window.event;
if(ev.keyCode == 13){
alert("我要提交表單了");
}
}
</script>
</head>
<body>
<h3>按下回車(chē)鍵，有驚喜</h3>

<script type="text/javascript">
document.onkeydown = function(ev){
ev = ev || window.event;

alert("我要提交表單了");
}
}
</script>
</head>
<body>
<h3>按下回車(chē)鍵，有驚喜</h3>

</html>
第二種方法：jquery實(shí)現(xiàn)（ie8、chrome和firefox都支持）
復(fù)制代碼代碼如下:
<html>
<head>
<title> javascript 實(shí)現(xiàn)回車(chē)鍵提交表單</title>
<meta http-equiv="content-type" content="text/html;charset=utf-8" />
<script type="text/javascript" src="jquery-1.8.2.min.js"></script>
<script type="text/javascript">
$(function(){
$(document).keydown(function(e){
var curKey = e.which;
if(curKey == 13){
alert("我要提交表單了");
}
});
});
</script>
