sharepoint 2013 在office 365中 如何嵌入JS代码实现搜索功能

先写标题，开会后手敲文字。

 <script language="javascript" type="text/javascript">
        function show() {
            var msg = document.getElementById('topsearch');
            var k = msg.value;
            window.open('/search/Pages/results.aspx?k=' + k + '', '', 'height=768,width=1024,toolbar=yes,resizable=yes,location=yes,menubar=yes,scrollbars=yes,status=yes');
        }
        function cleartext() {
            if (document.getElementById('topsearch').value == "搜索此网站...") {
                document.getElementById('topsearch').value = "";
            }
        }
        function pop(url) { window.open(url); }
    </script>

 <table width="220" height="18" border="0" cellpadding="0" cellspacing="0" bgcolor="white">
              <tr>
                <td width="200"><input name="topsearch" type="text" id="topsearch" value="搜索此网站..." size="160" maxlength="160" onfocus="cleartext()" onkeydown="if (event.keyCode==13) show();"  style="width:160px;" /></td>
                <td width="20" align="left" valign="middle"><label>
                  <input type="image" name="Submit" value="" style="width:13; height:13" src="/_layouts/cofcomaster/images/fdj_06.gif" onclick="show()" />
                </label></td>
              </tr>
            </table>
