例如:
原始码

[Copy to clipboard] [ - ]CODE:
function fastreply(subject) {
if($('postform')) {
$('postform').subject.value = subject;
$('postform').message.focus();
}
}

加密:

[Copy to clipboard] [ - ]CODE:
eval(function(p,a,c,k,e,d){e=function(c){return(c¦ ¬(¡){«($('¢')){$('¢').¡.¨=¡;$('¢').ª.©()}}',12,12,'subject|postform|script|javascript|type|function|text|value|focus|message|if|fastreply'.split('|'),0,{}))
