If you need to use a 24 bit PNG in IE6 and want it to work, you’re going to need a little help. First, start by creating a new stylesheet just for IE6, call it ‘f**kYouIE6.css’ or whatever you’d like. Then call the css with the following code after all of your other CSS calls.

<!--[if lt IE 7]>
<link rel="stylesheet" type="text/css" href="css/ie6Blows.css">
<![endif]-->

Then, in your CSS file, add the following property to whatever class/id/object will be using the alpha layer transparency.

img {
filter: progid:DXImageTransform.Microsoft.AlphaImageLoader("images/button.png");
}

please keep in mind, that if you’re making a website for anybody other than yourself, the aforementioned naming conventions for css files is strongly discouraged.

204. url += chiave + "=" + encodeURIComponent(valore) + "&"; //encodeURIComponent removes special characters that may break the key/value pair.

If you enter an apostrophe, it thinks the string has ended. If you enter an ampersand it thinks you’re joining a new key/value pair. So we just encode those (and all) values that would otherwise break the code.  Pretty simple solution to an annoying problem.

Further documentation: W3Schools – encodeURIComponent

The button on your form should look something like this:

<button id="submit" onclick="validate(event); return false;">Send Email</button> the return false prevents the default action here

The validation code might go something like this:

function foo(evt){

evt = evt || window.event;

var theform = document.contactForm; //this is how I capture my form, by using the form's name

/* validation code can go here */

if (isvalid){ //a test i'm using based on validation requirements

theform.submit(); //will submit the form
}

//the following test will cancel bubbling and default actions across the form, we use this for IE.
if (evt.stopPropagation)

evt.cancelBubble = true;


}

Essentially what you’re doing is stopping the browsers natural reaction to an event, such as clicking the submit button on the form and letting it run through your validation code. The added lines at the bottom prevent certain browsers from continuing on with the default actions even though you’ve coded return false; in your button click. Thanks Internet Explorer.
