Skip to comments (31) cross browser XMLHttpRequest
Posted by Erik on Oct 29 2005 @ 20:19 :: 9211 unique visits

With AJAX programming being so populair these days I thought I post this.

CODE: JAVASCRIPT

function createXMLHttpRequest() {

  var types = [

    'Microsoft.XMLHTTP',

    'MSXML2.XMLHTTP.5.0',

    'MSXML2.XMLHTTP.4.0',

    'MSXML2.XMLHTTP.3.0',

    'MSXML2.XMLHTTP'

   ];

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

    try {

      return new ActiveXObject(types[i]);

    } catch(e) {} 

  }

  try {

    return new XMLHttpRequest();

  } catch(e) { }

  return false; // XMLHttpRequest not supported

}

Modified the function after guest posting.

You can also use this code to add a XMLHttpRequest to IE so you can just use
new XMLHttpRequest(); as in other browsers.

CODE: JAVASCRIPT

if (!window.XMLHttpRequest) {

   window.XMLHttpRequest = function() {

      var types = [

        'Microsoft.XMLHTTP',

        'MSXML2.XMLHTTP.5.0',

        'MSXML2.XMLHTTP.4.0',

        'MSXML2.XMLHTTP.3.0',

        'MSXML2.XMLHTTP'

       ];

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

         try             {

           return new ActiveXObject(types[i]);

         } catch(e) {}

       }

       return false; // XMLHttpRequest not supported

    }

}

lol, no I can't (this link will). But if you don't know what an XMLHttpRequest does you will probably never need this code.

I think this version works better and is more stable:

CODE: JAVASCRIPT

function createXMLHttpRequest()

{

    // Create and initialise the temporary variable

    var http_request = false;

    // This check is for Mozilla, Safari, Opera,...

    if (window.XMLHttpRequest)

    {

        try

        {

            http_request = new XMLHttpRequest();

            if (http_request.overrideMimeType)

            {

                http_request.overrideMimeType('text/xml');

            }

        }

        catch (e)

        {

            http_request = false;

        }

    }

    // For Internet Explorer

    else

    {

        try

        {

            http_request = new ActiveXObject("Msxml2.XMLHTTP");

        }

        catch (e)

        {

            try

            {

                http_request = new ActiveXObject("Microsoft.XMLHTTP");

            }

            catch (e)

            {

                http_request = false;

            }

        }

    }

    return (http_request != null && http_request != false) ? http_request : false;

}

hehe, the function in the startpost will also work correctly and maybe better, because return wil exit the function after it's called, so he won't reach te next line. ;)

Looks interresting. I will do some tests with this and then probably modify the code I submitted.

7. On Dec 14 2005 @ 23:09 Erik wrote:

Found some problems today. When XMLHttpRequest is not supported createXMLHttpRequest returns null. But when you compare the result to null you will get an error in IE (not in firefox).

CODE: JAVASCRIPT

var req = createXMLHttpRequest();

if (req == null) { // error here

  ...

I have fixed this by letting the function return false and doing the check like this:

CODE: JAVASCRIPT

var req = createXMLHttpRequest();

if (typeof req == 'boolean') { // error here

  ...

Way to teach a dog infected with love and enjoyment of the people around them is dog training. Not all the people who keep the dog know how to train a puppy, but who often find it impossible to carry out dog obedience training , people who have a different feel that they do so. Although some people will tend to the field of veterinary medicine, other people will choose more specific career dog. Perhaps the most popular dog-centric professional area is that dog training.
Police dog training is a great way for those who love the dogs, to help them use and dissemination of information. One important thing to remember is that the dog trainer can not only teach dog tricks and working dogs and their masters. In fact, owners tend to play a bigger roll than the dogs training process.
Some people choose to learn some dog training tips from an experienced coach or a veterinary surgeon of similar projects in the apprenticeship. This is often useful, because many of these puppies training experience in the field and constant practice. Customers will often choose a coach approved no more than one certification. Other routes may be the next dog learning how to train a puppy through the animal science program behavior.

Do you know how to lose weight? No matter how you do, do not skip breakfast. People who began the day a good healthy breakfast does not have loss weight diet throughout the day than those who do not eat breakfast. Or, if you prefer to drink your breakfast to reach weight loss, fruit juice is a good choice. All you need to do is the integration and go! Super simple!
In addition, how to lose pounds? Plan your meals so you eat every 3-4 hours, about 5-6 times a day. Do you want to ensure that your last meal is 3-4 hours, and then go to bed. It seems to eat more frequently in the first strange, but studies ways to lose weight by the books and internet, you’ll not only lose pounds success, but also have the energy level of the day.

Are you annoying with belly fat? I am sure you hear that sit-ups are one of the best belly fat exercises. How to lose belly fat? There are not only belly fat exercises, but have belly fat diet. Although it is entirely correct sit-ups will strengthen the abdominal muscles and make you more powerful in this regard, you may get rid of belly fat because you’re fat to improve the muscle to hold better, which in fact did not lose belly fat itself.
The key to lose belly fat is actually quite simple. Therefore, these two key points, first of all to take action to belly fat exercises, second, have belly fat diet every day. Do these, you will lose belly fat!

As a child, you can find kids jobs to get money. If not, maybe you are considering how to make children work in additional funds. jobs for 15 year olds are so many. However, we know that you will not find a real job; you just need a working pocket money. Finding jobs for 16 year olds is not a difficult task.

To make money online, first you need to make necessary preparations. In any field or industry you need in all walks of life through appropriate channels to meet their own, in order to succeed. Can you imagine how to starting your own business? It would be a good way to Make Money on the Internet and move forward at full speed is going to just be disastrous.
In the network marketing, you can set up shop online, start flower shop, or you can start carpet cleaning business.In my opinion, there are also other popular ways to make money,for instance, So starting a laundromat business at home, another way is to manage furniture making business at home.
