问题描述
当我按下文本框上的回车键时如何防止表单自动提交？
解决方案
< script type = text / jscript language = javascript >
function submitButton（）{
if（window.event.keyCode == 0）{
return false;
}
else {
return true;
}
}
< / script >
你的按钮应该是这样的：
< form id =form1runat =serveronsubmit =return submitButton（）>
如果这是正确的，则标记为答案。
< script type = text / javascript >
function disableSubmitOnEnter（event）{
if（！event）
event = window.event
var keycode;
if（event.which）
keycode = event.which
else
var keycode = event.keyCode
if（keycode == 13）
return假;
else返回true;
}
< / script >
< input type =textonkeydown =return disableSubmitOnEnter（事件）; />

how to prevent auto submit of form when i press enter key on textbox?
解决方案
<script type="text/jscript" language="javascript"> function submitButton() { if (window.event.keyCode == 0) { return false; } else { return true; } } </script>
your button should like this:
<form id="form1" runat="server" onsubmit="return submitButton()">
If this is correct then Marked as Answer.
<script type="text/javascript"> function disableSubmitOnEnter(event) { if (!event) event = window.event var keycode; if (event.which) keycode = event.which else var keycode = event.keyCode if (keycode == 13) return false; else return true; } </script>
<input type="text" onkeydown="return disableSubmitOnEnter(event);" />
