加密是把部分字符转化为了unicode，我只能解到这里:(
var OxOe1b4=["dialogArguments","","<tr>","<td style='align: left; height: 20; font-size: 12px; ' bgcolor=white width='18' align=center onClick='getchar(this)' onmouseover='spcOver(this)' onmouseout='spcOut(this)' title='","' >","&#",";","</td>","</tr>","background","style","#0A246A","color","white","black","Verdana","innerHTML","Unicode","innerText","<span style='font-family:","'>","</span>"];
