Short note of Javascript refresher

			September 28th, 2009 
			

				
In the program i made, which tabulates the latest 20 call in a minute, I’ve found some good resource for it.

My setup, perl-cgi script is the one that generates the list of calls. This script is just called via an Ajax function.


The main important part of that is  part that contains this setInterval.

I chose setInterval since the “Call Accounting System” i made needs a refreshing every minute to update

the user about the activity of PBX.


The code also requires to have an id “content” to have the content generated by “refresher.cgi” displayed.

An example of usage will be.


<div id=”content”>&nbsp;</div>


and i put the code at the bottom of the html page.


<script type=”text/javascript” src=”20records.js”></script>


Below is the content of the 20records.js file:


var xmlhttp;


function showList()

{

xmlhttp=GetXmlHttpObject();

if (xmlhttp==null)

  {

  alert ("Browser does not support HTTP Request");

  return;

  }

var url="refresher.cgi";

url=url+"?sid="+Math.random();

xmlhttp.onreadystatechange=stateChanged;

xmlhttp.open("GET",url,true);

xmlhttp.send(null);

}


function stateChanged()

{

if (xmlhttp.readyState==4)

{


document.getElementById('content').innerHTML = xmlhttp.responseText;

}

}


function GetXmlHttpObject()

{

if (window.XMLHttpRequest)

  {

  // code for IE7+, Firefox, Chrome, Opera, Safari

  return new XMLHttpRequest();

  }

if (window.ActiveXObject)

  {

  // code for IE6, IE5

  return new ActiveXObject("Microsoft.XMLHTTP");

  }

return null;

}

window.setInterval("showList();",60000)

			

		
		
 

		
		

		
			
A notes UTF8 in MySQL and PHP

			May 12th, 2009 
			

				
According to Wikipedia, the Congo Region has 3 countries, the 2 Congo countries and the Angola.


I was tasked to list the countries all over the world and that includes the two (2) countries of Congo called Republic of the Congo (Congo-Brazzaville) and the Democratic Republic of the Congo (Congo-Kinshasa).


The addition of the dash – thing on the country to identify that separate country rendered some special unknown characters in both IE and Firefox browser. So upon seeing the content of the combo-box that contains the list of the country, this 2 country was rendered then as Congo <special character> Kinshasa and Congo <special character> Brazzaville.  I thought that was just the result of the uploads via LOAD DATA INFILE command of Mysql yet when I browse the code via mysql client console, the dash stays there.  Later I realize that this UTF8 thing really made that difference.


Thus using the command :

mysql_query("SET NAMES 'utf8'");

resolves that issue.
