自已練功，解決Javascript編碼的問題(破解)

其實，這不是我發生的問題，是廸亞哥的問題，我大概知道解法，就拿這隻apycom.com的jquery下拉選單(drop down menu)來開刀。其實處理的方式沒有很難。只是因為他寫的javascript code太機車，會擋到程式設計師debug的訊息，我才決定拿他開刀的。我不反對版權，但是，這樣的版權提示訊息不能造成使用者的不便，造成使用者的不便，結果使用者跑來吵我，那就不能怪我囉！所以兇手是廸亞哥，我只是共犯。

加密的地方在menu的js，一共有3段加密，前一段是jquery.easing.js V1.3版的內容，第二段是jquery easing compatibility V1的內js內容。我是不知道為什apycom.com拿別人的code過來還加密。拾人牙慧嗎？如果要拾人牙慧，有種的話把板權宣告拿掉，做絕一點，直接擾亂視聽，覺得怎樣啊？重點來了，會造成「No back link」字樣的code在第三段編碼。

傳統的做法，都是在eval(function(p,a,c,k,e,d)這個地方，把eval改成alert或是document.write，這樣，就會把解編碼過後的結果顯示在螢幕上。

最後一投換掉即可，前兩段要換也可以，等下提供
顯示出來的結果其中有一段，就是造成問題的地方

if (document.body){
var box = document.createElement(‘div’);
box.innerHTML = ‘<div style=”z-index:9999;visibility:visible;display:block;padding:3px;font:bold 11px Arial;background-color:#95d13d;position:absolute;top:10px;left:10px;”><a style=”color:#000;” href=”http://defencew.blog.163.com/blog/http://apycom.com/”>No back link</a></div>’;
document.body.appendChild(box);
}
return false;

拿掉之後，乾淨的第三段內容解編碼如下

jQuery(function(){ var $ = jQuery;
// retarder
$.fn.retarder = function(delay, method){

var node = this;

if (node.length){

if (node[0]._timer_) clearTimeout(node[0]._timer_);

node[0]._timer_ = setTimeout(function(){ method(node); }, delay);

}

return this;

};

(function(){

var links = document.getElementsByTagName(‘a’);

for (var i = 0; i < links.length; i++){

if (links[i].href && /^http:\/\/(?:www\.|)apycom\.com[\/]*$/i.test(links[i].href))

return true;

}
return false;

})();
$(‘#menu’).addClass(‘js-active’);if($.browser.msie&&parseInt($.browser.version)==7)
$(‘#menu’).addClass(‘ie7’);$(‘ul div’,’#menu’).css(‘visibility’,’hidden’);$(‘.menu>li’,’#menu’).hover(function()
{var ul=$(‘div:first’,this);if(ul.length){if(!ul[0].hei)ul[0].hei=ul.height();ul.css({height:20,overflow:’hidden’}).retarder(500,function(i){$(‘#menu’).removeClass(‘js-active’);$(‘a:first’,ul[0].parentNode).addClass(‘over’);$(‘#menu>ul>li.back’).css(‘display’,’none’);i.css(‘visibility’,’visible’).animate({height:ul[0].hei},{duration:500,complete:function(){ul.css(‘overflow’,’visible’)}})})}},function(){var ul=$(‘div:first’,this);if(ul.length){var css={visibility:’hidden’,height:ul[0].hei};$(‘#menu>ul>li.back’).css(‘display’,’block’);$(‘#menu’).addClass(‘js-active’);$(‘a:first’,ul[0].parentNode).removeClass(‘over’);ul.stop().retarder(1,function(i){i.css(css)})}});$(‘ul ul li’,’#menu’).hover(function(){var ul=$(‘div:first’,this);if(ul.length){if(!ul[0].wid)ul[0].wid=ul.width();ul.css({width:0,overflow:’hidden’}).retarder(100,function(i){i.css(‘visibility’,’visible’).animate({width:ul[0].wid},{duration:500,complete:function(){ul.css(‘overflow’,’visible’)}})})}},function(){var ul=$(‘div:first’,this);if(ul.length){var css={visibility:’hidden’,width:ul[0].wid};ul.stop().retarder(1,function(i){i.css(css)})}});$(‘#menu ul.menu’).lavaLamp({speed:400});if($.browser.msie&&$.browser.version.substr(0,1)==’6′){$(‘ul ul a span’,’#menu’).css(‘color’,’rgb(4,52,84)’).hover(function(){$(this).css({color:’rgb(255,255,255)’})},function(){$(this).css({color:’rgb(4,52,84)’})})}
else{$(‘ul ul a span’,’#menu’).css(‘color’,’rgb(4,52,84)’).hover(function(){$(this).animate({color:’rgb(255,255,255)’},500)},
function(){$(this).animate({color:’rgb(4,52,84)’},200)})}});

第一段和第二段編碼的內容如下，喜歡的話，可以貼回去
