Ajax :: Beginning - Nteraction Without Reloading The Page
Sep 22, 2009
I'm starting to learn Ajax after playing around with JSP and Javascript, I felt the need for interaction without reloading the page. I've searched everywhere for a simple java servlet/ajax example that I can play around with but just found a lot of asp and complex java examples. basic as typing a name in a text field and text being displayed beneath the text field after the word/letter has been typed. i.e. User must enter a name that is 3 or more letters else the text says "Error". I'm currently using Netbeans, so if the example could work there, that wold be preferable!

I'm trying to display content dynamically in a DIV My Script is a merge of two other scripts I found online one function (showUser) uses a GET method and the other (funcionPost) uses a POST method independently they work like a charm, but combined in the same script they throw some issues.
PHP Code:
<script type="text/javascript">
alert("Comienzo Script");
function getXMLObject() //XML OBJECT
{ alert("Comienzo ~ getXMLObject()");
var xmlHttp = false;
[Code]..

Something like starting animation to a page with about 10 jpgs. When the page start is starting slideshow fadein animation between about 10 large pics, and when the last one appears it stays as a background to content and buttons must appear when the last picture is loaded, too with fade in animation. Is sounds not so difficult, but for me become a hard task.

how to use $.ajax for the first time and I have a question specific to how I need to implement ajax.
I have a table that is dynamically built in php from a database. The user can click on an "Edit" link that is in each line/row in the table. When they do, a UI dialog pops up with the information from the line the user clicked on. When the user clicks the Submit button in the dialog box, $.ajax will send the info to a server-side script that will process the edited data.
I haven't yet implemented the above yet, but I have a pretty good grip on how to do what I have described above.
how to refresh the table to reflect the changes the user made in the dialog. This is AJAX, so I shouldn't have to reload the whole page - I'd imagine at the most the whole table. How do I do this?

It appears that one is being inserted by jquery and the other is being inserted by the normal form submission. How do I remove/override the normal form submission? My html code is as follows:

I have a page that has several layers that I will either show/hide
based on a graphic/tab that the user clicks. (works perfectly)
On several of the layers there are forms that the user can update
information on. Well, after the user updates the information, I need
to 1.) refresh the data on the page(means a reload of the page), and
2.) take the user right back to were they started.
My problem is that when I refresh, the page goes back to the 1st layer
that is set as default to show.
So, here is what I did. I have two functions.
Function 1 is called when the user clicks on one of the tabs (Assets)
in this case. This will 1.) show the Assets tab and 2.) hide all the
rest of the tabs.
Well if I update that form for Assets, I need to 1.) refresh the data
and 2.) bring the user right back to Assets.
What I did for this (please tell me if there is a better way) was to
set a hidden field with the lastlocation of where the user clicked. In
this case the field value is now set to Assets.
So far everything is working great...
Well, if I submit the form because I've updating information, I need to
return back to the assets layer. To do this I set the location.url and
put a var in the url that I evaluate when I OnLoad the page. If the
value = Assets then I am able to show/hide the layers to get to the
Assets.
Again, this works great after much banging of my head against the
wall... Here come the problem.
Because I set the location.URL (I've also tried location.href) the
browser will automatically refresh. I do not want this. I want to set
the url and only refresh when I want to.
For example when I submit a form that updates data.

Is there a way of reloading a page programatically - for example,
<script language="javascript>
document.location.reload()
</script>
BUT NOT HAVING TO MANUALLY CLICK A "RESET" BUTTOM.

I made a form with a tooltip function when you hover over an input field.But when I load the page, after about 500ms, the page turns white and the ""Loading..."-message from the browser stays forever.I found out that this is because of the tooltip function, especially the code:document.write(table)
Here's the javascript:
//////// Tooltip code

I have a div tag that I want to loop through and refresh at the end of the loop. I understand Ajax is probably the best option for this but how do I refresh just the div tag alone without reloading the page?
In the title I meant to say How do I refresh a div tag without reloading the page?

I have a window that generates a popup. In the popup a link takes you to a second page within the popup.In the 2nd page of the popup I have the following
Code:
<body onUnload="opener.location.replace(window.opener.location);">
This reloads the original parent window. This reloads the page but is causing the problems, the page seems to change but it is going to this URL
http://www.mysitehere.com/[object]
It should refresh the page but instead it is adding the [object] piece to the end.
Do you have any idea's on how to fix this (or an alternative)?

I'm trying to learn js &html5. now i have an issue. i'm working on a dice game (craps) using the html5 <canvas>. my dice are working fine but every time i click the "roll" button the page reloads which resets my form. the form provides feedback about the rolls. it includes the output of the counter variable, and win, lose, or shoot again info.
Html5 can be viewed at
Here is some of the js. if you need it all i'll post it later - just let me know.
Fyi- if i take the call to fxInit() out of the body tag in the html5 the canvas does not persist, it blinks with every (roll) onClick Event
I have used ie9 js debugger and it steps through flawlessly every time 4-5 counts .
var firstTurn = true;

I have a google map which shows a car moving along a line that it reads from xml.the problem is that if the user clicks the button again without reloading the page, the map moves but the car remains at its last point.From what I can figure out, this means that the startAnimation() function has restarted but the animate(d) function has not restarted. but trying to call the animate(d) function from the button, where the startAnimation() gets called,is there some way of resetting the animate(d) function when the startAnimation() function gets called, so everything goes back to the start? Or is there some other way of "refreshing" everything without reloading the page?

I'm trying to create a feature similar to facebooks "like" system.
I have a page with peoples posts in, and when someone clicks on "like", I want to first run the query to insert a new like into the database, then reload just the number of likes, without refreshing the entire page.
I know this way is harder but I want it to work without reloading everything. Here's what I have so far:
function for like (reverse engineered, might be completely wrong..)
function like(){
$('#postoptions').load('php_files/likecount.php');
}
postoptions.php
[Code]....
I know that at the moment there is no query to add an entry to the database when clicking on the like link, but I'm not too sure how to put it. I tried putting this:
$addLike = "INSERT INTOlike (username, postid) VALUES ('$username','$postid')";
$run = mysql_query($addLike) or die(mysql_error());
but because the posts are loaded with a while loop, clicking like on one made me like all of them on that page.
I though reloading the "likecount.php" page would reload the count for the page?

I'm trying to reload some dynamic content that is contained within div tags without refreshing the entire page. After some searching it appears that Ajax is my best bet, but I have never worked with JQuery before.
Here is the code snippet from the page containing the data I'm looking to refresh when a user click the "update" form button:
Code:
<div id="data">
<table cellpadding="0" cellspacing="2">
<tr>
[Code]....
As you can see I'm currently just reloading the entire page, which is weak.

I work mostly in PHP, with just a bit of JavaScript when necessary. I've inherited an app that among other things, uploads files to the server. When the user clicks the "Save" button, it targets an invisible iframe and actions the php upload script -- that is:
Code:
<form action="doupload.php" method="post" enctype="multipart/form-data" name="doupload" target="doupload_iframe_target">
The outer, top level window has the icons for the files uploaded so far, and the total number.
The upload works fine, but the icons & total count don't get updated in the outer window unless I manually click refresh on the browser. Naturally, I'd like the new number and icon list to appear automatically after an upload, so I tried putting both:
window.location.reload(); and parent.location.reload();
at the end of the doupload.php script within the iframe (appropriately encapsulated in <script> </script>).
Both of which work, sort of, but they apparently repost the data to the iframe, which causes the upload to be re-executed, which then causes the reload to happen again, for an endless loop.
If I manually refresh the browser page from the firefox toolbar, this doesn't happen; it just refreshes and shows the new total number & appropriate icons.
So obviously I'm out of my depth here with the javascript and dom structure. I want to refresh the top window without reposting to the iframe.

how to do the following, here is a simplified example:
Let's say I have a database of pictures of animals. A search for "pets" is performed and it loads a page of thumbnail images. Somewhere on the page is a list of other search criteria (text link or checkbox) that would narrow the initial returned results. An example would be "cats", "dogs", "hamster", etc.
Is there a way after the initial search is performed that the results could be further filtered without having to hit a submit button and reload the page?

I am embedding several youtube videos on a page, by default, youtube videos do not autoplay.
To get them to autoplay, one simply appends &autoplay=1 to the youtube url.
E.g. http://www.youtube.com/v/6YR0LGK_HHA&autoplay=1
(will autoplay)
As opposed to:
http://www.youtube.com/v/6YR0LGK_HHA
(will not autoplay)
Does anyone know of a cool trick for being able to do this when the client clicks on a JS link labelled Play Video (without refreshing the page)? Code:

I have a set of tabs that are set with an href that adds a query string to the url such as "?t=1", meaning the first tab is selected.
Technically it works just fine but every time I click a tab it reloads the page and I'm not entirely sure how to stop this.
I'm using a jquery plugin to handle the query strings. Here's the plugin [URL].
Here's the piece of the code that matters:
var url = location.search;
var tab = $.query.get('t');
init(tab);
function init(tab){

Is it possible to alter the query string of the current URL without triggering a page load.
eg. Say you have AJAX pagination, allowing people to change pages without the whole page reloading, just the content of the paginated area. However in case somebody bookmarked the page, they would really only be bookmarking the page 1 - even if they were on page 10.
So, what I was wondering is if it is possible when a user clicks Next, Previous, or Page 10, 15 etc, to alter (with javascript/jQuery) the URL (shown in the browser navigation bar) so that it reflects the page number they are on.
I am sure something like this is possible, either that or it is a damn fast connection. When I browse photos in somebody's photo album in Facebook, the photo loads with AJAX, yet the URL query string changes to reflect the current photo. And all this happens without any obvious full page reload. It appears that the URL/query string is being updated using Javascript while the photo changes using AJAX.
