Need Help To Combine Functions

[Schrene]

I am still learning.

How would I combine these?

Or not repeat “The variable that makes Ajax possible” part of the code.

[code]function showID(){
var idRequest; // The variable that makes Ajax possible!

try{
	// Opera 8.0+, Firefox, Safari
	idRequest = new XMLHttpRequest();
} catch (e){
	// Internet Explorer Browsers
	try{
		idRequest = new ActiveXObject("Msxml2.XMLHTTP");
	} catch (e) {
		try{
			idRequest = new ActiveXObject("Microsoft.XMLHTTP");
		} catch (e){
			// Something went wrong
			alert("Your browser broke!");
			return false;
		}
	}
}


idRequest.onreadystatechange = function(){
	if(idRequest.readyState == 4){
		var idDisplay = document.getElementById('color_id');
		idDisplay.innerHTML = idRequest.responseText;
	}
}
var color = document.getElementById('color').value;

var queryString = "?color=" + color;
idRequest.open("GET", "colorfil_data_color_id.php" + queryString, true);
idRequest.send(null); 

}
function showName(){
var nameRequest; // The variable that makes Ajax possible!

try{
	// Opera 8.0+, Firefox, Safari
	nameRequest = new XMLHttpRequest();
} catch (e){
	// Internet Explorer Browsers
	try{
		nameRequest = new ActiveXObject("Msxml2.XMLHTTP");
	} catch (e) {
		try{
			nameRequest = new ActiveXObject("Microsoft.XMLHTTP");
		} catch (e){
			// Something went wrong
			alert("Your browser broke!");
			return false;
		}
	}
}


nameRequest.onreadystatechange = function(){
	if(nameRequest.readyState == 4){
		var nameDisplay = document.getElementById('color_name');
		nameDisplay.innerHTML = nameRequest.responseText;
	}
}
var color = document.getElementById('color').value;

var queryString = "?color=" + color;
nameRequest.open("GET", "colorfil_data_color_name.php" + queryString, true);
nameRequest.send(null); 

}
function showNum(){
var numRequest; // The variable that makes Ajax possible!

try{
	// Opera 8.0+, Firefox, Safari
	numRequest = new XMLHttpRequest();
} catch (e){
	// Internet Explorer Browsers
	try{
		numRequest = new ActiveXObject("Msxml2.XMLHTTP");
	} catch (e) {
		try{
			numRequest = new ActiveXObject("Microsoft.XMLHTTP");
		} catch (e){
			// Something went wrong
			alert("Your browser broke!");
			return false;
		}
	}
}


numRequest.onreadystatechange = function(){
	if(numRequest.readyState == 4){
		var numDisplay = document.getElementById('color_num');
		numDisplay.innerHTML = numRequest.responseText;
	}
}
var color = document.getElementById('color').value;

var queryString = "?color=" + color;
numRequest.open("GET", "colorfil_data_color_num.php" + queryString, true);
numRequest.send(null); 

}[/code]

Thanks in advance for your help ;D
