1.在body处
<body onkeydown="on_return(event);">
2.声明一下js代码
<script type="text/javascript">
window.onload = function () { document.getElementById('account').value = '' } //账号框
window.onload = function () { document.getElementById('pwd').value = '' } //密码框
function on_return(event){
if(event.keyCode == 13){
if (document.all('login') != null) {
document.all('login').click(); //登陆按钮id
}
}
}
</script>
3.登陆按钮加点击事件
onclick="check()"
