怎么设置回车键触发某个button按钮

<script language="javascript">        function SubmitKeyClick()        {               if (event.keyCode == 13)             {                     event.keyCode=9;              event.returnValue = false;              document.all('button1').click();            }}
</script>
<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title>无标题页</title>
    <script>
    function cli()
    {
        location.href="http://www.sina.com";
    }

    function bin()
    {
         if (event.keyCode == 13)
         {
            document.getElementById('Button1').click();
         }
    }
    </script>

</head>
<body onkeydown="bin()">
    <form id="form1" runat="server">
    <div>
        <input id="Button1" type="button" value="button" onclick="cli()" /></div>
    </form>
</body>
</html>
在你的代码文件中Page_Load()事件里加上这段代码：
假设你页面的form的id为fm，button的id为btn

  protected   HtmlForm   fm;
  string   ref=Page.GetPostBackEventReference(btn);
  fm.Attributes.Add("onkeydown","if(event.keyCode==13){if(PageValidate(){"+ref+";}}");
