高手来帮忙看一行取随机数Javascript语句

Question

怎么可能随机呢？这表达的参数就没变过。function test(){return ((((((((((0x0fffffff^104)|100)^101)|104)^104)^105)^102)|107)^102)&107);}var s = "";
for (var i = 0; i < 10; i++)
s += test() + "\r\n";
alert(s);测试一下就知道了。都是9。

Answer 1

链接地址是啥？或者可调试的html。总之先让我们能看到效果。

Answer 2

是校内的网页游戏“古惑仔”里的银行页面
http://mob.xiaonei.com/bank.do这是里面的一部分源码<div id="m_content">
    <div class="mc_innerWrap">
        <h2>银行<span class="lime">(银行存款：$9000)</span></h2>
        
        <script type="text/javascript">
            function xn_rand_function(){ return ((((((((((0x0fffffff&101)^101)|100)&108)|107)&104)&101)^101)|107)|102);}
        </script>
        <table class="item_table" cellspacing="3" cellpadding="0">
            <tbody>
                <tr>
                    <th width="55%">取款</th>
                    <th width="45%">存款</th>
                </tr>
                <tr>
                    <td>
                        <form id="withdrawform" name="withdrawform" action="/withdraw.do" method="post">
                            <input type="hidden" name="key" value="2010076141224993911317"/>

                        </form>
                        <p>取款是免费的</p>
                    </td>
                    <td>
                        <form id="depositform" name="depositform" action="/deposit.do" method="post" onsubmit="return doEnt();">

                            <input id="run2" type="hidden" name="run" value="2">

                        <p>存款收取<em>10%</em>的费用</p>
                    </td>
                </tr>
            </tbody>
        </table>
        <script>
            function doSub(o) {
                var pr = o.previousSibling;
                if (!/^\d+$/.test(pr.value)) {
                    alert("请输入数字！");
                    pr.focus();
                    return false;
                }
                $('run1').value = xn_rand_function();
                $('run2').value = xn_rand_function();
                o.parentNode.submit();
            }            function doEnt() {
                var pr = $('depositvalue');
                if (!/^\d+$/.test(pr.value)) {
                    alert("请输入数字！");
                    pr.focus();
                    return false;
                }
                $('run2').value = xn_rand_function();
                return true;
            }
        </script>
    </div>
</div>
下面是点击depositform中的存款按钮时，我通过抓包得到的页面POST的数据：
key=2010076141224993911317&run=111&depositCash=1317
