The smallest Ajax library - jx has been very useful for me - so much that it found its way to the common.js file of the Bin-Co site. So I thought that I will release a slightly updated version.
// jx Library - http://binnyva.blogspot.com/2006/02/jx-ajax-library-in-object-notation.html (Version 1.01.A)
var jx = {
http : false,
getHTTPObject : function() {
var xmlhttp = false;
if(typeof ActiveXObject != 'undefined') {
try {xmlhttp = new ActiveXObject("Msxml2.XMLHTTP");}
catch (e) {
try {xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");}
catch (E) {xmlhttp = false;}
}
} else if (XMLHttpRequest) {
xmlhttp = new XMLHttpRequest();
}
return xmlhttp;
},
getData : function(url,callback,type) {
if(!this.http) {
this.init();
if(!this.http) return;
}
if(!type) var type = "text";
this.http.open("GET", url, true);
this.http.onreadystatechange = function () {
if (jx.http.readyState == 4) {
var result = "";
if(jx.http.responseText) result = jx.http.responseText;
type = type.toLowerCase();
if(type == "json" || type == "j") result = eval(result);
if(callback) callback(result);
}
}
this.http.send(null);
},
init : function() {
this.http = this.getHTTPObject();
}
}
//////////////// Init ///////////
//Call it like this.
function init() {
jx.getData("data.php?id=3&whatever=something",function (data) {
alert(data);
},'t');
}
window.onload=init;
Changes
Very little changes to speak of, but here goes.
- Removed the comments to make the code smaller - if you need to see how the code works, see the original post on the jx Ajax Library.
- Don't have to call the jx.init() function - the script does it automatically.
- Made the code smaller.
- Some more small changes.
