form태그 내 input(type=text) 1개일 시, input에서 엔터키입력=>자동 submit

case1. input(text) 1개일 때 자동 서브밋을 그대로 이용. (onkeypress 를 넣지 않음)

========================================================

<script>

function check(){

if(!(document.f.pwd.value=="1234"))

return false;

}

</script>

<form action="2.jsp" method="post" name="password" onsubmit="return check()">

<input type="text" name="pwd">

</form>

=========================================================

case2. 강제로 input(text) 2개를 만듬. (추천?)

=========================================================

<script>

function enter(){

if (event.keyCode == 13)

check();

}

function check(){

if( document.f.pwd.value=="1234")

password.submit();

else

return false;

}

</script>

<form action="2.jsp" method="post" name="password" onsubmit="return check()">

<input type="text" name="pwd" onkeyperss="enter()">

<input type="text" style="display: none;">

</form>
