[gs038538]

网页源码是~~~~

<td width="50%" valign="top">
<h2 style="color: black">Choose your new plan</h2>

<span style="line-height: 150%">

<input type="radio" name="planTag" value="linode1024.4" id="linode1024.4"><label for="linode1024.4">Linode 1024</label><br>

<input type="radio" name="planTag" value="linode2048.4" id="linode2048.4" disabled><label for="linode2048.4"><strike>Linode 2048</strike></label> (current plan)<br>

<input type="radio" name="planTag" value="linode4096.4" id="linode4096.4"><label for="linode4096.4">Linode 4096</label><br>

<input type="radio" name="planTag" value="linode8192.4" id="linode8192.4"><label for="linode8192.4">Linode 8192</label><br>

<input type="radio" name="planTag" value="linode16384.4" id="linode16384.4"><label for="linode16384.4">Linode 16384</label><br>

<input type="radio" name="planTag" value="linode32768.4" id="linode32768.4"><label for="linode32768.4">Linode 32768</label><br>

<input type="radio" name="planTag" value="linode49152.4" id="linode49152.4"><label for="linode49152.4">Linode 49152</label><br>

<input type="radio" name="planTag" value="linode65536.4" id="linode65536.4"><label for="linode65536.4">Linode 65536</label><br>

<input type="radio" name="planTag" value="linode98304.4" id="linode98304.4"><label for="linode98304.4">Linode 98304</label><br>

</span>

<br>
<input type="submit" class="button" name="doit" value="Resize this Linode Now!" onClick="return confirm('Immediately shut down, migrate your Linode, and invoice this account for the difference?')">

</td>



需要选中 <input type="radio" name="planTag" value="linode2048.4" id="linode2048.4" disabled>
然后 <input type="submit" class="button" name="doit" value="Resize this Linode Now!" onClick="return confirm('Immediately shut down, migrate your Linode, and invoice this account for the difference?')">
然后对话框提示 onClick="return confirm('Immediately shut down, migrate your Linode, and invoice this account for the difference? 要点确认~~

重复以上步骤直到刷出来~~~


参考脚本如下，肯定是错误的，不知道怎么修改成正确的~~求大大指点。
谢谢！

window.setTimeout(YTFunc, 3000);
