Updating an area with new text inputed by user?

[Sim]

I want to create an ajax mud and I was wondering how to update an area of text with new text that is retreived from the mySQL database from the command giving by the user?

element.innerHTML is a very common method.

The innerHTML property sets the contents of the element and causes the browser to render any html that's included.

Check out my AJAX preferences, I did exactly what your looking for with the all of it, but namely the User Signatures - which will probably help you most.

* Keep in mind I use the Dojo Toolkit for the AJAX calls here.

[20:58] <floydian> what's confusing ya about what I said in the forum?

[20:58] <Sim> I dunno. what I do with innerHtml?

[20:59] <floydian> first, you need to "get" the element you're putting the response into

[20:59] <floydian> have you done that?

[20:59] <Sim> hmm No. I don't know where to even begin with ajax. I downloaded an ajax chat example to try to learn from but it doesn't use mySQL. it uses a txt file.

[21:00] <floydian> (and to make the thread make sense, I'll post what's said here so it closes up that thread nicely)

[21:00] <Sim> Sounds good to me.

[21:00] <floydian> it sounds like you need to study some ajax examples then

[21:01] <floydian> there's lots of them out there

[21:01] <Sim> http://ce.pastebin.com/m26c7883c

[21:02] <Sim> I can figure out how to write to mySQL file without refreshing page.

[21:02] <Sim> just not read from and update from mySQL

[21:03] <Sim> Is it as simple as echoing? ;]

[21:03] <floydian> #

[21:03] <floydian> function ajax_read(url) {

[21:03] <floydian> when you do that function call

[21:03] <floydian> the URL you put in there

[21:03] <floydian> will be executed as a normal page would

[21:03] <floydian> and yes, anything you echo from that file that is executed

[21:04] <floydian> would be placed into the web page

[21:04] <floydian> by

[21:04] <floydian> document.getElementById("chatwindow").innerHTML = xmlhttp.responseText;

my php file:

is a simple: echo $_GET['m'] . '

';

Re: Updating an area with new text inputed by user?

That recursive call to ajax_read() is killing the script. And you still have the script outside of the HTML tags...
