一定是先要有submit reset对应设置onsubmit，onreset
函数1：id来获得对象，用来调对象的value
函数2：msg+=
<!doctype html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>表单提交、重置事件的应用</title>
<style type="text/css">
fieldset{width:300px;height:150px;}
</style>
<script language="javascript" type="text/javascript">
function $(id){return document.getElementById(id);}
function submitTest(){
var msg ="用户名:"+$("input1").value;
msg+="\n密码:是"+$("input2").value;
alert(msg);
return false;
}
function resetTest(){alert("将数据清空");}
</script>
</head>
<body>
<form onsubmit="return submitTest();" onreset="resetTest()">
<fieldset>
<legend>表单数据提交</legend>
<br><label>用户名：</label><input type="text" id="input1">
<br><label>密 码：</label><input type="password" id="input2">
<br><input type="submit" value="提交">
<input type="reset" value="重置">
</fieldset>
</form>
</body>
</html>
