<input type="button" name="ButtonMSDN" value="MSDN搜索" onclick="window.location='http://www.microsoft.com/china/msdn/searchredir.aspx?qu='+encodeURIComponent(tbMSDN.value)">
<input type="button" name="ButtonMSDN" value="MSDN搜索" onclick="window.location='http://www.microsoft.com/china/msdn/searchredir.aspx?qu='+encodeURIComponent(tbMSDN.value)">
