DOM cookies and Javascript

 

You can create Cookies via DOM and set them in JavaScript. Cookies are name and value bindings - that exists during a session between a client and user.

 

 

Basic Code to Set Cookie using Javascript

function SetCookie (name, value) {

var argv = SetCookie.arguments;
var argc = SetCookie.arguments.length;
var expires = (argc > 2) ? argv[2] : null;
var path = (argc > 3) ? argv[3] : null;
var domain = (argc > 4) ? argv[4] : null;
var secure = (argc > 5) ? argv[5] : false;
document.cookie = name + "=" + escape (value) +
((expires == null) ? "" : ("; expires=" + expires.toGMTString())) + ((path == null) ? "" : ("; path=" + path)) +
((domain == null) ? "" : ("; domain=" + domain)) +
((secure == true) ? "; secure" : "");

}

 

 

Basic Code to Get Cookie

// Get Cookie function
function GetCookie(name) {
var arg = name+"=";
var alen = arg.length;
var clen = document.cookie.length;
var i = 0;
while (i < clen) {
var j = i + alen;
if (document.cookie.substring(i, j) == arg) return getCookieVal(j);
i = document.cookie.indexOf(" ", i) + 1;
if (i == 0) break;
}
return null;
}

 

Call above function to get cookie associated with the name "order_submitted"

var prod1=GetCookie("order_submitted");
