Latar belakang
Pengakses web saat ini beragam, tidak hanya dari PC desktop saja, namun bnayak juga dari perangkat bergerak (mobile device). Ada kalanya yang punya web tidak mempersiapkan secara khusus tampilan web yang user friendly jika diakses dari perangkat mobile yang punya keterbatasan dalam tampila, resource dan akses data. Intinya kalau diakses dari mobile device harus bisa lebih simpel supaya cepat dan hemat data (bagi pengakses).
Skenario Sistem
Skenario sistem kita memang tidak punya punya 2 web yang satu khusus untuk desktop dan satunya khusus untuk mobile. Script Redirect web Jika diakses dari HP / Smartphone ini menggunakan javascript yang langsung bisa pasangkan di web kita. skenarionya sebagai berikut :
- Website1 utama design awalnya memang untuk diakses dari PC /Desktop
- Ada Website2 yang disiapkan secara khusus bisa untuk Mobile/Desktop fleksibel
- Jika ada yang akses dari Mobile browser ke website1 akan diredirect ke Website2 secara otomatis
- Jika sudah di website2 (versi mobile) pingin balik ke Website1 (vesti Desktop) masih tetap bisa.
Saya menggunakan script yang ada di sini untuk Implementasi ini.
[code language=”javascript”]
<script type=”text/javascript”>
function setCookie(c_name, value, exdays) {
c_name = c_name.toLowerCase();
var exdate = new Date();
exdate.setDate(exdate.getDate() + exdays);
var c_value = escape(value) + ((exdays == null) ? “” : “; expires=” + exdate.toUTCString());
document.cookie = c_name + “=” + c_value;
}
function getCookie(c_name) {
c_name = c_name.toLowerCase();
var i, x, y, ARRcookies = document.cookie.split(“;”);
for (i = 0; i < ARRcookies.length; i++) {
x = ARRcookies[i].substr(0, ARRcookies[i].indexOf(“=”));
y = ARRcookies[i].substr(ARRcookies[i].indexOf(“=”) + 1);
x = x.replace(/^\s+|\s+$/g, “”);
if (x == c_name) {
//alert(“x = ” + x);
return unescape(y);
}
}
}
function getQuerystring(key, default_) {
key = key.toLowerCase();
//alert(“key : ” + key);
//alert(“default_ : ” + default_);
if (default_ == null) default_ = “”;
key = key.replace(/[\[]/, “\\\[“).replace(/[\]]/, “\\\]”);
var regex = new RegExp(“[\\?&]” + key + “=([^&#]*)”);
var qs = regex.exec(window.location.href.toLowerCase());
if (qs == null) {
//alert(“default_ : ” + default_);
return default_;
}
else {
//alert(“qs[1] : ” + qs[1]);
return qs[1];
}
}
function detectMobileAndRedirect(a,b){
// alert(location.href);

Sementara untuk menambahkan link balik ke website1 (Versi Desktop) anda bisa gunakan tag ahref dengan sedikit modifikasi seperti ini :
<a href="http://www.YourSite.com/?ViewFullSite=true">View Full Site</a></p>
