asp.net – 如何禁用提交行为的asp：ImageButton？

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);");

如果您需要完全禁用Enter键提交表单.案例使用< body>上的OnKeyDown处理程序标签在你的页面上

JavaScript代码：

if (window.event.keyCode == 13) 
{
    event.returnValue = false; 
    event.cancel = true;
}

使用JQuery这将会更清洁,更容易和推荐的方法.您可以使用以下扩展名：

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>
