Cookie Handling Routines in JavaScript

These routines are not rocket science, but they do provide a complete set of easy-to-use cookie handling routines in JavaScript. You will find below demonstrations of all the routines, together with the calling sequences used.

(Session Cookies + Persistent Cookies)

The following routines are provided in the zip file:

1) Test to see if session cookies are enabled.
2) Test to see if persistent cookies are enabled.
3) Write a session cookie
4) Write a persistent cookie
5) Get value of a named cookie
6) Delete a persistent cookie

JavaScript: Regular Expression on Domains (2 methods)

Method 1:

//-- section = 0 : index+sub-index, 1 : content --//

var section="0";

var str = document.location.href;



var url_pattern=new Array(

"^news.sina.com.hk$",

"^news.sina.com.hk/$",

"^news.sina.com.hk/index.html$",

"^/cgi-bin/nw/realtime.cgi$",

"^/cgi-bin/nw/main.cgi[?]cat=2$",

"^/cgi-bin/nw/main.cgi[?]cat=19$",

"^/cgi-bin/nw/international.cgi$",

"^/cgi-bin/nw/china.cgi$",

"^/cgi-bin/nw/main.cgi[?]cat=15$",

"^/cgi-bin/nw/main.cgi[?]cat=22$",

"^/cgi-bin/nw/main.cgi[?]cat=23$",

"^/cgi-bin/vote/index.cgi$",

"^/cgi-bin/nw/special.cgi$"

);



for(var i=0; i{

   if(new RegExp(url_pattern[i]).test(str))

   {

      section="0";

   }

   else

   {

      section="1";

   }

}



if(section=="0") {

   alert("index");

}

else {

   alert("content");

}

Method 2:

var as_section='ros'; //all page are ros except match the following

var as_curr_url = document.location.href;

    as_curr_url= as_curr_url.replace(RegExp("^http://"+location.hostname), '');



var as_exact_match = new Array(

"/",

"/index.html",

"/cgi-bin/nw/realtime.cgi",

"/cgi-bin/nw/main.cgi?cat=2",

"/cgi-bin/nw/main.cgi?cat=19",

"/cgi-bin/nw/international.cgi",

"/cgi-bin/nw/china.cgi",

"/cgi-bin/nw/main.cgi?cat=15",

"/cgi-bin/nw/main.cgi?cat=22",

"/cgi-bin/nw/main.cgi?cat=23",

"/cgi-bin/vote/index.cgi",

"/cgi-bin/nw/special.cgi"

);



var as_pattern = new Array(

//"/test/regex.html$"

);

                   

for ( var i = 0; i < as_exact_match.length; i++) {

  if (as_exact_match[i] == as_curr_url) {

  	as_section='index'; break;

  }

}



if (as_section == "ros"){

  for ( var i = 0; i < as_pattern.length; i++) {

    if (as_curr_url.match(as_pattern[i])) {

  	  as_section='index'; break;

    }

  }

}



if(as_section == 'index'){

   alert("index");

}else {

   alert("content");

}       

JavaScript: detect browser width and align layer to center

Equation:

var x = (document.body.clientWidth/2) - 364;

P.S. Banner Width (728)/ 2 = 364
