第一步：把如下代码加入到head区域中
SCRIPT LANGUAGE="JavaScript"
!-- Begin
function Encrypt(theText) {
output = new String;
Temp = new Array();
Temp2 = new Array();
TextSize = theText.length;
for (i = 0; i TextSize; i++) {
rnd = Math.round(Math.random() * 122) + 68;
Temp[i] = theText.charCodeAt(i) + rnd;
Temp2[i] = rnd;
}
for (i = 0; i TextSize; i++) {
output += String.fromCharCode(Temp[i], Temp2[i]);
}
return output;
}
function unEncrypt(theText) {
output = new String;
Temp = new Array();
Temp2 = new Array();
TextSize = theText.length;
for (i = 0; i TextSize; i++) {
Temp[i] = theText.charCodeAt(i);
Temp2[i] = theText.charCodeAt(i + 1);
}
for (i = 0; i TextSize; i = i+2) {
output += String.fromCharCode(Temp[i] - Temp2[i]);
}
return output;
}
// End --
/script
第二步：把如下代码加入到body区域中
