Im coding a chat system, but the main thing which I cannot get working which is stopping me from doing this is displaying the data from the database. I have made a test XML document for the time being so that I can get the JavaScript/AJAX working properly, then I will figure out why my PHP isnt generating the XML file properly. Here is my XML document:

I have a form that asynchronously submits to a PHP file. The PHP file returns the following:
PHP Code:
echo json_encode($array);
In my Console, I see the following:
Response:
{"groupname":"XYZ Group","id":4}
How do I display that JSON code through jQuery code?
Here's the jQuery code I have so far:
Code:
$.post("addgroup.php", { groupname:f.groupname },
function(data){
$("#groups tr:last")
.clone(true)
.insertAfter("#groups tr:last")
.html("<td class='tbldata'>"+ /* Returned JSON data (groupname) */ +"</td><td class='tbldata'> /* Returned JSON data (id) */ </td>");
I have a PHP file which is called upon through AJAX. The PHP file "fetch.php" searches the database with the given JS variables, an x and y co-ordinate, through GET, and brings back the user id associated with those co-ordinates. So I then get that users information... I'm then trying to bring those PHP variables back into the AJAX call on the original page and display the results. Here's what I've got so far...
Javascript/jQuery
Code JavaScript:
<script type="text/javascript">
jQuery.fn.elementlocation = function() {
var curleft = 0;
var curtop = 0;
var obj = this;
do {
curleft += obj.attr('offsetLeft');
curtop += obj.attr('offsetTop');
obj = obj.offsetParent();
} while ( obj.attr('tagName') != 'BODY' ); .....
Everything is working fine, except one thing, I've check the php file and it does echo a username so I know there is a result being sent back from my query. It's just I can't seem to get the user_name_area and user_online_area to display the results from the fetch.php file. Am I parsing them correctly, do I have to assign them to a variable or is what I'm trying to do impossible? I've never attempted this whole json thing before and I seem to be having some problems with it.
I have a <input type = file> button for uploading a file in my php page. As soon as i select a file from the button, i need the file data to be displayed so that i check whether the file selected has the correct data. How can i do this.

I'm writing a script and I've encountered a problem.. I have a txt file with many words, each word in a different line. For example: the file words.txt contains:
word1
word2
word3
word4
word5
I need to load the content of the file into a variable in my script. I prefer that all the words will be in the same variable with line breaks, but if you'll figure out a way to put it in an array, it's ok too. I really don't know how to do it, and I tried to google but didn't understand.. By the way, I don't want to change the txt file to js file, I need it to remain txt..

I want to display the time in a particular timezone (US Central) regardless
where the computer is located. I have written the script below which
displays the time in the Eastern, Central, Mountain, Pacific and Alaska time
zones in the US. It works okay if the computer is located in the Central

Central time. Can anyone offer any suggestions?

View 1 Replies View RelatedI want to display an image using javascript instead of HTML (or use javascript to change the HTML code dynamically when an update is made). I have created an XML file, which contains text data which is displayed in HTML by using Javascript.What I am having trouble with is getting Javascript to grab the image URL from the XML file, and then display that image in the correct div. How does one show an image by using javascript? and how do you get javascript to get the url from the XML?
So what I want to do is create a function that grabs the url (relative) from the PIC tag in the XML ("newssmall.jpg") and then uses this URL to display the image on the HTML page.This way, only the XML needs updating when updating the news section of the site.
I wrote a function (shown below) that is to take numbers from <div> tags add them up and display the value in a different <div> tag. It also prints the total in a hidden input tag to be sent when submitted.All was working fine until today I noticed that the total was no longer showing up in either the <div> tag or the hidden input tag.on change of any of the select menus correctly displays the expected value in its corresponding <div> tag.I have no Idea what might be causing this, so I need fresh eyes.

I searched the forum on how to display a year. What I want to do is include the code so that the copyright year will automatically change without me manually changing it every year. I found the following code when doing a search in codingforums. Can I use this code on my site?
<SCRIPT LANGUAGE="JavaScript">
<!-- Begin
var year=new Date().getYear();
if ( window.ActiveXObject ) {
document.write("" + year + "");
} else {
document.write("" + parseInt(year + 1900) + "");
}
// End -->
</SCRIPT>
Also, some sites have the original year the website was created for the copyright. Others have the current year, and yet others have the created year thru the current year. Is there any 'rule' on what is supposed to be displayed?
The problem we are having now is that it does not show the php design in all browsers. It displays just fine in firefox but in in ie and crome it has no style, can anyone advise on how we would get it to display the styling that the php has without having to heavily modify this javascript code.

I've got this bit if JavaScript that loads a Flash applet. It also has a noscript tag in case the user has JavaScript turned off.Works great in all browsers I've tried, but it doesn't work at all in IE8 (nor IE7 emulated). Even the noscript content isn't showing up.W3C validator shows no issues.I've even tried lowering the browser security with no change -- but that wouldn't have been a good solution if it had worked anyway; I can't tell my visitors to lower their browser security.

I got an [object error] from IE 7.0.5730.11 when moving the <script
src="..." type="text/javascript" /tag from the <headpart to the
<bodysection of a HTML file.
Is not possibile to include Javascript code via <script src="..."
type="text/javascript" /from the <bodysection, instead from the
<headone? If yes, anyone has any idea of which the problem could be?
If not, how can I programmatically include a javascript external file

to some particular native functions?
is there a way to assign an event to a file input so that when a user selects a file to upload the event is triggered and i can check out the file extension? The reason why is simple, i want to perform different actions depending on the type of the file.
View 2 Replies View RelatedI'm trying to put in place a file upload validation check. So at the client-side, the User selects a file. Before uploading, at the GUI, if the file exceeds an imposed limit, it will prompt the User that it exceeds the permitted size for upload.
And if it is within the permitted size, the full file path of the file to be uploaded will then be obtained and then used for the actual upload to the Server.
