这种JS如何才能知道代码？求解。。。。

使用google浏览器，打开浏览器，然后按f12，选择console，然后{"\x48\x6F\x6D\x65":{"\x55\x72\x6C":document["\x55\x52\x4C"],"\x54\x70\x6C":"\x64\x65\x66\x61\x6C\x75\x74","\x43\x68\x61\x6E\x6E\x65\x6C":"","\x47\x65\x74\x43\x68\x61\x6E\x6E\x65\x6C":function (_0xa267x1){if(_0xa267x1=="\x31"){return "\x76\x6F\x64";} ;if(_0xa267x1=="\x32"){return "\x6E\x65\x77\x73";} ;if(_0xa267x1=="\x33"){return "\x73\x70\x65\x63\x69\x61\x6C";} ;} ,"\x4A\x73":function (){this["\x43\x68\x61\x6E\x6E\x65\x6C"]=this.GetChannel(Sid);if($("\x23\x77\x64")["\x6C\x65\x6E\x67\x74\x68"]>0){$key="输入影片名称或主演名称";if($("\x23\x77\x64")["\x76\x61\x6C"]()==""){$("\x23\x77\x64")["\x76\x61\x6C"]($key);} ;$("\x23\x77\x64")["\x66\x6F\x63\x75\x73"](function (){if($("\x23\x77\x64")["\x76\x61\x6C"]()==$key){$("\x23\x77\x64")["\x76\x61\x6C"]("");} ;} );$("\x23\x77\x64")["\x62\x6C\x75\x72"](function (){if($("\x23\x77\x64")["\x76\x61\x6C"]()==""){$("\x23\x77\x64")["\x76\x61\x6C"]($key);} ;} );} ;$("\x23\x66\x61\x76")["\x63\x6C\x69\x63\x6B"](function (){var _0xa267x2=window["\x6C\x6F\x63\x61\x74\x69\x6F\x6E"]["\x68\x72\x65\x66"];try{window["\x65\x78\x74\x65\x72\x6E\x61\x6C"]["\x61\x64\x64\x46\x61\x76\x6F\x72\x69\x74\x65"](_0xa267x2,document["\x74\x69\x74\x6C\x65"]);} catch(err){try{window["\x73\x69\x64\x65\x62\x61\x72"]["\x61\x64\x64\x50\x61\x6E\x65\x6C"](document["\x74\x69\x74\x6C\x65"],_0xa267x2,"");}
前后这个前后添加'',复制到console下面，然后直接按enter键就可以看到了

var FF={"Home":{"Url":document["URL"],"Tpl":"defalut","Channel":"","GetChannel":function (_0xa267x1){if(_0xa267x1=="1"){return "vod";} ;if(_0xa267x1=="2"){return "news";} ;if(_0xa267x1=="3"){return "special";} ;} ,"Js":function (){this["Channel"]=this.GetChannel(Sid);if($("#wd")["length"]>0){$key="输入影片名称或主演名称";if($("#wd")["val"]()==""){$("#wd")["val"]($key);} ;$("#wd")["focus"](function (){if($("#wd")["val"]()==$key){$("#wd")["val"]("");} ;} );$("#wd")["blur"](function (){if($("#wd")["val"]()==""){$("#wd")["val"]($key);} ;} );} ;$("#fav")["click"](function (){var _0xa267x2=window["location"]["href"];try{window["external"]["addFavorite"](_0xa267x2,document["title"]);} catch(err){try{window["sidebar"]["addPanel"](document["title"],_0xa267x2,"");}

这里有JS脚本可以实现转换：

你也可以用chrome浏览器进行查看。方法@m1989mmm有介绍了。

\x74这类明显是16进制的字符，转换下就可以了
