推荐答案
我会假设你有某种输入控件，你不想要一个回车键preSS自动提交当用户意外击中进入键。如果是这样你可以一个javascript安其preSS事件附加到要禁用此行为为每个控制。
I will assume you have some sort of input controls and you don't want an enter keypress to auto submit when a user accident hits the enter key. If so you can attach a javascript onkeypress event to each control that you want to disable this behavior for.
function disableEnterKey(e)
{
var key;
if (window.event) key = window.event.keyCode; // Internet Explorer
else key = e.which;
return (key != 13);
}
// In your aspx file Page_Load do the following foreach control you want to disable
// the enter key for:
txtYourTextBox.Attributes.Add("OnKeyPress", "return disableEnterKey(event);");
如果你需要禁用完全回车键提交表单。情况下使用的onkeydown处理器上＆LT;车身方式＆gt; 在页面上标记
If you need to disable the Enter key submitting form completely. case use the OnKeyDown handler on <body> tag on your page.
JavaScript的code：
The javascript code:
if (window.event.keyCode == 13)
{
event.returnValue = false;
event.cancel = true;
}
与jQuery这将是更清洁，更容易和推荐的方法。你可以提出延期使用：
With JQuery this would be much cleaner, easier and the recommended method. You could make an extension with:
jQuery.fn.DisableEnterKey =
function()
{
return this.each(function()
{
$(this).keydown(function(e)
{
var key = e.charCode || e.keyCode || 0;
// return false for the enter key
return (key != 13);
})
})
};
// You can then wire it up by just adding this code for each control:
<script type="text/javascript" language="javascript">
$('#txtYourTextBox').DisableEnterKey();
</script>
