JS set method to get cookies _javascript tips

Combining the JavaScript authority guide with the data collected on the Web during project development, two methods of setting up and getting cookies were sorted out.

Copy Code code as follows:

<script>

Set Cookie Method One
function Setcookie (name,value) {
var exp = new Date ();
Exp.settime (Exp.gettime () + 1*60*60*1000);/valid for 1 hours
Document.cookie = name + "=" + Escape (value) + "expires=" + exp.togmtstring ();
}

* * Access to the cookie is generally easy to inject characters to encode, the corresponding in the acquisition of cookies to decode, there are many ways to encode, there is time to write a blog about encoding and decoding * *

Set Cookie method two to store cookies directly
Document.cookie = "homepage = http://www.jb51.net";

/*-------------------------------------------------------------------------------------------------------*/

A method of taking cookies function
function GetCookie (name) {

var arr = Document.cookie.match (New RegExp ("(^|)" +name+ "= ([^;] *)(;|$)"));

if (arr!= null)

Return unescape (arr[2]);

return null;

}

Method of fetching Cookies function two
function GetCookie (key) {
if (key==null)
return null;
if (Object.prototype.toString.call (key) = = ' [Object String] ' | | Object.prototype.toString.call (key) = = ' [object number] ')
{
var arrstr = Document.cookie.split (";");
for (var i= 0;i<arrstr.length;i++) {
var temp = arrstr[i].split ("=");
if (Temp[0]==key)
Return unescape (temp[1]);
}
return null;
}
return null;
}

</script>

In learning a lot of JS methods encountered will not be on the Internet to find information, until mastered.
