Changing Elements Content Without Refreshing Page?

Sep 3, 2010

What website do any of you recommend for learning Javascript browser compatibility? I'd like to learn more about acceptable javascript programming.

I am using the script below for changing elements content without refreshing my page. Typically it works fine on recent Mozilla and IE releases if they haven't had too many hijacked settings. I know this isn't really much of an excuse for a script not to execute if it is done properly so I am hoping someone here can help me make what I have more compatible with more settings and browsers.

Changing And Refreshing Div Content

Jun 22, 2007

I have a website with some navigation buttons on top. When one button is clicked I replace it's content with the content of a red button using this code:

document.getElementById('button').innerHTML = '
<a href="javascript:void(0)">
<img src="header/button_active.jpg" border="0" />
</a>'
The original code was enclosed in a DIV and I cant just change the img src because the original code is:

<div id="aanbiedingen">
<a href="javascript:void(0)">
<img src="1px_tranceparent.gif" name="Aanbiedingen" width="99px" height="20px" border="0" />
</a>
</div>

But when the orignal button is clicked, a ajax event goes off and loads the new page without reloading the button.
Using this code a button becomkes red once you click it. This is what I want.

Just one problem: when I click on another button, the first one stays red because it doesn't reload the page. Now I thought, I'll refresh the navigation page using a div and ajax. Code:

Nov 30, 2010

Im not sure if im going about this the right way but what I'm trying to achieve is to have my webpage seperated into two main div's.The first div contains a media player so it cant be refreshed or the media stops.The second div is used to view content.I've used innerHTML to change the content of the second div from links in the first.The problem is the URL displayed doesn't reflect the change in content of the second divI want to be able to load content into the second div using innerHTML while changing the URL so people can link directly to that content

Changing Data Without Refreshing Page

Oct 16, 2005

Given some recent success on a simple form validation (mainly due to
the kind folks in this forum), I've tried to tackle something a bit
more difficult. I'm pulling data down from a database and populating a
simple table. I'd like the table to contain 10 entries per page and
have the option for the user to scroll through the pages of data
without having to go back to refresh the page (I've already pulled all
the info I need from the database). So, I've taken a stab at it and
this is probably not the best way to do it (so if you have a better
idea I'm open), but I think it will work. Right now I'm encountering
an 'Object Expected' error and I don't know how to interpret what it's
telling me. Code:

Content Generation Without Page Refreshing?

Aug 19, 2009

I am teaching myself javascript and in the course of my experimentation have run into this roadblock: I want to display a styled navigation bar with a button beneath it. When the button is clicked, an onclick event will be triggered and the response of the browser should be to print the word "test" right beneath the button. However, what actually happens is the page blanks out and the word 'test' appears in the upper left corner of the screen.

CODE

<html>
<head>
<title>JavaScript Navanimation Example</title>
<style type="text/css">

Refreshing The Random Content?

Mar 12, 2011

What would be the jQuery-based way of refreshing random content that is currently managed by PHP?

PHP Code:

$num = Rand (1,5);switch ($num) {case 1:echo '<div>Random content</div>';break;// and so on...} 

I'd like to add the option to refresh this content with jQuery. I'm not sure how this might work (I'm only an amateur coder and not familiar with JS beyond using plugins). Would it be as simple as adding an ID to each div and then somehow displaying a new div at each click of an anchor? It doesn't really need to be random: in number order would be fine. I want to keep the underlying PHP method, or a near equivalent, so that it degrades nicely.

opening the app again".

Changing Elements In Page "onclick" With IFrames?

Jul 19, 2010

I'm new to this forum and am trying to find answers to a few issues I've been having. I'm building a website for my music (I'm a novice with web design so bear with me) and I'm having trouble with this page - [URL]...

As you can see, when you click on the "Filter By" buttons, the relevant gallery opens in the iFrame and the Titles (such as Latest Photos and Live Photos) are altered onclick by using the changeText function. The problem with this is that when I use the browser "Back" button, the iFrame goes back, but the "changeText" doesn't go with it.

So I've been trying to find solutions to this. Someone on another forum suggested hiding the album titles in a hidden element on each gallery page, and the title in when you click on the Filter By buttons. They suggested first putting some code such as: <input type="hidden" name="AlbumTitle" value="Live Photos">

Page Refreshing Issue

Sep 4, 2006

here's a few lines of code I've got in a page that has a php database query in it and I want it to arrive at the anchor link I have called "bottom each time"

<script language="javascript">

function loadPage()
{
location.href = "http://www.mysite.com/help/chat/chat_window.php?theID=<?php echo $id; ?>";
}

</script>

</head>

<body bgcolor="#CCCCCC" onLoad="setTimeout('loadPage()',20000)">

The page has enough data to produce scrollbars. Is there something I'm doing wrong?

Ajax :: Refreshing A Page With PHP?

Nov 14, 2008

The user enters their info, the info is sent to the php page through ajax, the php checks if the input fields are empty and checks if the info is correct.If fields are empty or the info is wrong, it updates a div layer with an error message telling them what is wrong.

My problem though is if the user enters correct info. If the user enters correct info I want the main page (index.php) to be refreshed (This is the page with the original form on it).This is my java script:

function createRequestObject() {
var ro;
var browser = navigator.appName;
if(browser == "Microsoft Internet Explorer"){

[code]....

I've tried various things with the meta tag, including updating multiple parts of the page (using ID|<blah> instead of just a plain echo) and a couple other things. None of them will get the original page itself to reload.

Refreshing A Page From Within A Popup

Feb 3, 2006

I'm working on this system, where an admin can manage articles and stuff. The editing, adding and deleting of articles is done from within a Javascript popup. When the new article is added, the admin can hit a "close this window"-link to return to the admin-page, which contains a list of all articles.

This works fine, however, when returning to the list-page, the new article hasn't been added to the list, because there was no page refresh. Is there any way to invoke a page refresh from within the editing-popup?

Refreshing A Div - Refreshing A Div Were For Updating Dropdown Boxes ?

Jun 6, 2009

I have been searching high and low on how to do this and I think I'm at a loss because I'm so unfamiliar with js and ajax.What I would like to do is have just a single div on a page refresh every 5-10 secs; the content of the div shows what users are logged on; the content is generated by a query on my db

<div id="players"><?php
$online_query = "SELECT user_log.user_id,user_log.ip,user_log.logged_in,user_log.logged_out,users.username,users.type_id FROM user_log LEFT JOIN users ON user_log.user_id=users.id WHERE user_log.logged_in IS NOT NULL AND user_log.logged_out IS NULL ORDER BY users.username";[code]....

almost all of the google results I got for refreshing a div were for updating dropdown boxes or dealt with some kind of page event...so now I'm at a loss on what else to look for..

JQuery :: Update Page Without Refreshing?

Jun 2, 2011

I came across this product page at nordstrom that allows users to filter products by certain criteria (size, fit, price, etc). [URL]..

They use ajax to update the page with any new criteria that users select, but with each page update the page url also changes and the browser history shows the new page. This is done without refreshing the page.

how this is done: creating a new page in browser history but without refreshing the page?

Updating The PHP Information Without Refreshing The Page?

My codes at the moment read:

$recentnumrows = mysql_num_rows($recentupdates);

[Code]....

the codes works of course. But I want it to be updated automatically when a new post has been made.

Reloading A Number Without Refreshing The Page?

May 2, 2011

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?
