Recently I decided to try reducing the size of hacking the HTTP request for cross browser support in AJAX. This little snippet has been tested and is working.

1 2 3 4 |
// new xml http object
var xmlHttp = new XMLHttpRequest() ? new XMLHttpRequest() :
( new ActiveXObject("Msxml2.XMLHTTP") ? new ActiveXObject("Msxml2.XMLHTTP") :
( new ActiveXObject("Microsoft.XMLHTTP") ? new ActiveXObject("Microsoft.XMLHTTP") : null ) ); |
I find this new method easier to read and is much more elegant than the method bellow; which is the only method I’ve seen out there.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
try{
// Firefox, Opera 8.0+, Safari
xml=new XMLHttpRequest();
}catch(e){
// Internet Explorer
try{
xml=new ActiveXObject("Msxml2.XMLHTTP");
}catch(e){
try{
xml=new ActiveXObject("Microsoft.XMLHTTP");
}catch(e){
alert("Your browser does not support AJAX!");
return false;
}
}

I know that I am not the only who has tried to shorten this section of code. Let me know what you think or how you handle it yourself.
