:) You're welcome.

The new window must be interpreted as HTML. If you name the page with a php extension (.php) then the server should interpret it as HTML, and execute the JavaScript.

However, you can also send...

Usually, if it is a regular download, then the filename is in the Content-Disposition header.

However, it really depends on how you structure your HTTP Response. You can easily send the filename...

Something that might interest you is that before you could do XMLHttpRequest, the basis of AJAX, you could create Iframes programmatically with client side scripting.

Back then it was called...

The Form has to be submitted by the browser, instead of programmatically via JavaScript, in order to send the file contents.

The Iframe does not belong to the same document. So the browser can...

It is a good exercise.

Something not really used in JS is the second parameter of parseInt().

You can use it to convert between bases:

eg:

// binary to decimal
parseInt('101', 2); // 5

So converting between...

Something like this should work:

/**
* Return html numeric entities encoded string
*/
String.prototype.toHtmlEntities = function() {
return this.replace(/[^a-z0-9\.\-\_\s\t]/ig, function(c)...

You can create or display and HTML Element, that has the message.

Example of creating one:

var msg = documement.createElement('div');
msg.innerHTML = 'Your message';

Then attach that div...

BTW: in the parent, you'll have defined the function: uploadDone()

eg:

function uploadDone(status) {

if (status) alert('upload complete');
else alert('upload error');

}

Yes, unfortunatley you can't use XMLHttpRequest to upload a file fro the users computer.

The reason is that JavaScript does not have access to the file contents. It only has access to the file...

Mozilla is working on getting location into the browser:
http://labs.mozilla.com/2008/10/introducing-geode/

You'll need a service that does the location guessing for you at the moment.

Loki...

You're welcome. :)

newDiv.innerHTML = '<input type="file" name="' + divIDName + '" size="57"> <a href="#" onclick="removeAdditionalFile(this.parentNode, this.count)">Remove</a>';

this.count would refer to the...

Glad you got it solved - too bad it wasn't exactly how you wanted.

There is a good example on the page I linked.

All you need to do is take the response from the HTTP Request (AJAX Call) and use eval to turn that string into an actual JavaScript Object.

...

You can execute JS by using eval(). If the JavaScript is specifically JSON, then you can use JSON library.

Its actually displaying, but breaks the layout. The images come outside of the main box. So I think you may just have a CSS problem.

btw: You sent me the link to index.php which you mention:

Do you get any JS errors?

Firefox has a great extension called Firebug. It has good JS debugging. Safari and Chrome also have similar debuggers/consoles.

Changing the url you have the AJAX...

A change it the URL path won't affect "AJAX". Only a domain change, such as a subdomain.

So it must be something else in your code.

If you're trying to remove the last element in the array, use Array.pop() instead.
https://developer.mozilla.org/En/Core_JavaScript_1.5_Reference/Global_Objects/Array

However, your splice looks...

If you're using Firefox, download Firebug. It will give you the error. Safari and Chrome also have a JS debugger/console built in.

Take a look at the window.location object:
https://developer.mozilla.org/en/DOM/window.location

I'm sure it would be relative to the canvas object. Wouldn't make any sense otherwise.

I'm not too familiar with canvas. I think I read somewhere that it isn't possbile to edit/manipulate...

Is it possible to redraw the canvas on however, or is that too slow?

see:

/**
* Parse strings into XML Object

textToXML: function(strXML) {...

You'll need to know a bit of JavaScript.

Basically, on each type of a few characters into the search input, you send the search to the server, and load the results.

eg: HTML

<input...

I've looked into this a bit. There is a similar exploit mentioned on Linux.com:

However, this works on a bug in Firefox which makes it populate the user and...

I've noticed this before but your post got me thinking about XSS and I just realized that it can be carried out even if you are not logged into a website.

The common misconception is that you...

I can't see anything wrong with your HTML at all.

You can't really target all browsers, especially old ones. If you do so, you would be limiting the site in newer ones. (But its really your...

IE5.0? wow, I don't think there are many of those around.

Do you get any error messages in IE5.0? Or is the page just blank?

You have the javascript within the PHP loop.

You need to take it out so that it loads only once.

JavaScript was designed for the browser and still is it's main use but its usefulness has outgrown just the browser.
It can run on the server side, just like PHP, Java etc.
It can be a standalone...

Very accurate discussion here:

I think that definition would mean that every programming language on a web server is a scripting language since it supports the web server's task of serving HTML. lol.. Just as JavaScript does it...

I think what you want is how to populate a second select box based on the selection in the first select box and/or vise versa. (which isn't really nested select boxes)

Basically, the steps are...

Normally XMLHttpRequest (XHR) can only be made to the same host.

Cross domain is only possible if the web service (remote host) implements it. Either using a workaround such as cookies, url...

Use try{ ... yoru code ... } catch(e) { alert(e); } to see whats going wrong.
XHR also requires the same origin for request and remote server. Even if www or a sub domain is considered a different...

How is your ezine subscription implmented? You'll need to be able to retrieve the list of users subscribed to your ezine, and have them insert their email, and/or password before carrying on.
