关于修改数量后自动提交的问题
<form id="form1" name="form1" method="post" action="">
<input name="num" type="text" id="num" />
</form>
现在要实现的功能，num域本来有个默认数量，如果修改了数量（和以前的数量不一样），失去焦点后，自动提交，不用点提交按钮，如何失现？
[解决办法]
- HTML code
<html xmlns="http://www.w3.org/1999/xhtml"><head> <title></title></head><body><form id="form1" name="form1" method="post" action=""> <input name="num" type="text" id="num" onchange='change()' value='10'/></form><script> function change() { form1.submit(); }</script></body></html>
[解决办法]
<script type="text/javascript">
function ss(){
document.forms[0].submit();
}
</script>
</head>
<body>
<form id="form1" name="form1" method="post" action="">
<input name="num" type="text" id="num" value="1" onchange="ss()"/>
</form>
</body>
</html>
这样？
