<script type="text/javascript">
            function MinNum(p1, p2) {
                return (p1 > p2) ? p2 : p1;
            }                
            
            $(function () {
                $("#btnShow").bind("click", function () {
                    $(".tip").html("");
                    var strTmp = "17与18中最小的数是：";
                    strTmp += MinNum(17,18);
                    //显示在页面中
                    $(".tip").show().append(strTmp);
                });
