Javascript Enter name: Output Enter name: Set Cookie Now your machine has a cookie called name. You can set multiple cookies using multiple key=value pairs separated by comma. Reading Cookies Reading a cookie is just as simple as writing one, because the value of the document.cookie object is the cookie. So you can use this string whenever you want to access the cookie. The document.cookie string will keep a list of name=value pairs separated by semicolons, where name is the name of a cookie and value is its string value. You can use strings' split() function to break a string into key and values as follows: Example Try the following example to get all the cookies.
Javascript // Get all the cookies pairs in an array cookiearray = allcookies.split(';'); } // Now take key value pair out of this array for(var i=0; i name = cookiearray[i].split('=')[0]; value = cookiearray[i].split('=')[1]; document.write ("Key is : " + name + " and Value is : " + value); click the following button and see the result: Note: Here length is a method of Array class which returns the length of an array. We will discuss Arrays in a separate chapter. By that time, please try to digest it. Output click the following button and see the result: Get Cookie Note: There may be some other cookies already set on your machine. The above code will display all the cookies set on your machine. 85
