I want to know if there is a way to display an external php file after clicking on a link, and then display another external file right below(not INSTEAD of) it after a different link was clicked. Here is my code.
index.html
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<div id="menu">

<li id="home">DOWNLOADS</li>
<li id="tutorials">ERRORS</li>
</ul>
</div>
<div id="content">

</body>
</html>
core.js
//On load page, init the timer which check if the there are anchor changes each 300 ms
$().ready(function(){
setInterval("checkAnchor()", 100);
});
var currentAnchor = null;
//Function which chek if there are anchor changes, if there are, sends the ajax petition
function checkAnchor(){
//Check if it has changes
if(currentAnchor != document.location.hash){
currentAnchor = document.location.hash;
//if there is not anchor, the loads the default section
if(!currentAnchor)
query = "page=1";
else
{
//Creates the string callback. This converts the url URL/#main&id=2 in URL/?section=main&id=2
var splits = currentAnchor.substring(1).split('&');
//Get the section
var page = splits[0];
delete splits[0];
//Create the params string
var params = splits.join('&');
var query = "page=" + page + params;
}
//Send the petition
$("#loading").show();
$.get("callbacks.php",query, function(data){
$("#content").html(data);
$("#loading").hide();
});
}
}
downloads.php
<b>DOWNLOADS</b>
errors.php
<b>ERRORS</b>
callbacks.php
<?php
//used to simulate more waiting for load the content, remove on yor projects!
sleep(1);
//Captures the petition and load the suitable section
switch($_GET['page']){
case "errors": include 'errors.php'; break;
case "downloads": include 'downloads.php'; break;
default: include 'downloads.php'; break;
}
?>
This works perfectly except it uses a switch and I want to be able to see both errors.php and downloads.php at the same time, not only one or the other.
EDIT
Pseudo code to make it clearer:
If download is clicked show download.php only. If error is clicked show error.php only(right after downloads.php) and don't remove downloads.php or any other external file that may or may not be included on the main page already.
Any suggestions?
p.s. I've looked through many, many threads about this and that's why I can't post all the code I've tried (sorry I can't include links either, last time my question was downvoted for doing that...>:/) so I can promise I've done my homework.
p.s.s. If you think this deserves a down vote please be kind enough to explain why. I'm open to criticism but just thumbs down is not helpful at all.
EDIT:
Updated core.js to
$(document).ready(function(){
$('#menu li a').click(function() {
var currentAnchor = $(this).attr('href');
if(!currentAnchor)
var query = "page=1";
else
{
var splits = currentAnchor.substring(1).split('&');
//Get the section
var page = splits[0];
delete splits[0];
//Create the params string
var params = splits.join('&');
var query = "page=" + page + params;
}
//Send the petition
$("#loading").show();
$.get("callbacks.php",query, function(data){
$("#content").html(data);
$("#loading").hide();
});
return false;
});
});

EDIT:
core.js (revised)
//On load page, init the timer which check if the there are anchor changes each 300 ms
$(document).ready(function(){
$('#menu li a').click(function() {
var currentAnchor = $(this).attr('href');
if(!currentAnchor)
var query = "page=1";
else
{
var splits = currentAnchor.substring(1).split('&');
//Get the section
var page = splits[0];
delete splits[0];
//Create the params string
var params = splits.join('&');
var query = "page=" + page + params;

$("#loading").show();
$.get("callbacks.php",query, function(data){
$("#content").html(data);
$("#loading").hide();
});
return false;
});
});

EDIT:
This one will "append" data [coming from either downloads or errors] to the existing content.
$.get("callbacks.php",query, function(data){
$("#content").append(data);
$("#loading").hide();
});
Hope this helps.
If you want to show both pages at once, in your callbacks.php page you should be able to do something like this (all I did was remove the switch statement):
include 'errors.php';
include 'downloads.php';
Any reason why you can't do this?

I want to change url without reload the page because Im using AJAX function to reload a div.
The problem is that when the AJAX load the div, it doesn't read the url parameter.
My code (I've already load the jquery.js etc.) :
index.php
<a href="#page=1" onClick='refresh()'> Link </a>
<a href="#page=2" onClick='refresh()'> Link2 </a>
<script type="text/javascript">
$.ajaxSetup ({
cache: false
});
function refresh() {
$("#test").load("mypage.php"); //Refresh
}
</script>
<div id="test">
</div>
mypage.php
<?php
if (isset($_GET['page'])){
$page = $_GET['page'];
}
echo $page;
?>
PHP can't read the fragment without reloading the page. This can be done using JS.
Below the script I use to read the parameter values without reloading the page. I don't think it's the best method there is, as there are plugins you could use to do the same (and much more), but it works. I found it online some time ago, but unfortunately I don't remember where :(
var urlParams;
(window.onpopstate = function () {
var match,
pl = /\+/g, // Regex for replacing addition symbol with a space
search = /([^&=]+)=?([^&]*)/g,
decode = function (s) { return decodeURIComponent(s.replace(pl, " ")); },
query = window.location.hash.slice(1);
urlParams = {};
while (match = search.exec(query)) {
urlParams[decode(match[1])] = decode(match[2]);
}
})();
You would then get the parameter value with:
urlParams['page']
If you will work a lot with hash urls, you should check out this plugin: http://benalman.com/projects/jquery-bbq-plugin/
Getting after # hash tag:
With PHP (Required page load)
parse_url() fragment index thats you need
$url = parse_url($_SERVER['REQUEST_URI']);
$url["fragment"]; //This variable contains the fragment
With jQuery: (Not required page load)
var hash = $(this).attr('href').split('#')[1];
var hash = $(this).attr('href').match(/#(.*$)/)[1];
Demo (Used without hash tag)
index.php
Link | Link2
<script type="text/javascript">
$(".myLink").click(function(e) { // when click myLink class
e.preventDefault(); // Do nothing
var pageId = $(this).attr('data-id'); // get page id from setted data-id tag
$.ajax({
type:'POST',
url:'mypage.php', // post to file
data: { id: pageId}, // post data id
success:function(response){
$("#test").html(response); // write into div on success function
}
});
});
</script>
<div id="test"></div>
mypage.php
<?php
// get with $_POST['id']
echo "Loaded Page ID: ".($_POST['id'] ? $_POST['id'] : "FAILED");
?>
You need to pass a page parameter to the URL you're requesting.
Try this:
<a href="#page=1" onClick='refresh(1)'> Link </a>
<a href="#page=2" onClick='refresh(2)'> Link2 </a>
<script type="text/javascript">
$.ajaxSetup ({
cache: false
});
function refresh(pageNumber) {
$("#test").load("mypage.php?page="+pageNumber); //Refresh
}
</script>
It is possible for you to pass parameters through the load() function in jQuery.
There are 2 common ways of doing so:
Using get:
JS:
$('#test').load('mypage.php?page=mypage');
PHP:
<?php
if (isset($_GET['page']))
{
$page = $_GET['page'];
}
echo $page;
?>
Or using data as a post:
JS:
$('#test').load('mypage.php', { page: mypage });
PHP:
if (isset($_POST['page']))
{
$page = $_POST['page'];
}
echo $page;
?>
New here and glad to be, I've gotten a lot of answers from this forum. I am however stuck at the moment.
I have some javascript that is creating a window color and handle picker (click on the color swatch it changes the image, click on a handle and it does the same). Below the image is a description of the window selected. This text is being generated by the javascript by pulling the image titles.
Now the fun part. Below this picker I need to add a form that will be emailed using php. Within that email I need to pull the window description that is being generated by the javascript.
I have tried so many things today I have lost count. The last bit of code I tried was
<script>
$(document).ready(function() {
$("windowDesc").each(function() {
var html = jQuery(this).html();
});
});
</script>
And in the php mail file I added:
$windowtitle = $_GET['html'];
as well as trying
$windowtitle = $_POST['html'];
and I have also tried the following:
<script>
var content = $('#windowDesc').html();
$.ajax({
url: 'send_mail.php',
type: 'POST',
data: {
content: content
}
});
</script>
And in the php mail file I added:
$windowtitle = $_GET['content'];
as well as trying
$windowtitle = $_POST['content'];
Not to mention a plethora of other things.
Basically what I am trying to do is grab the content of the div that holds the generated text and email it. If any of the above are correct then I must be placing them in the wrong position or something. With the first one I have tried it inside the form, outside the form, before the div, after the div. Just haven't tried it on top of my head yet. It's been a long day, thanks in advance :o)
Sorry for the delay, been a busy two days. OK, so here is the code that handles the window color and handle picker:
var Color = "color";
var Handle = "handledescription";
var ColorDesc = "color";
var HandleDesc = "handle description"
function Window(Color,Handle,ColorDesc,HandleDesc) {
$('#windowPic').animate({opacity: 0}, 250, function () {
thePicSrc = "http://www.site.com/images/windows/" + Color + Handle + ".jpg";
$('#windowPic').attr('src', thePicSrc);
$('#windowDesc').html("<p>" + ColorDesc + " frame with " + HandleDesc + " hardware</p>");
$('#windowPic').animate({opacity: 1}, 250)
})
}
$(document).ready(function() {
$('#wColors li').click( function() {
Color = $(this).attr('id');
ColorDesc = $(this).attr('title');
Window(Color,Handle,ColorDesc,HandleDesc);
});
$('#wHandles li').click( function() {
Handle = $(this).attr('id');
HandleDesc = $(this).attr('title');
Window(Color,Handle,ColorDesc,HandleDesc);
});
});
You need a hidden input in your form:
<form id="send_email" action="send_email.php">
<input id="content" type="hidden" name="content"/>
... other inputs here
</form>
Then you can use Javascript to fill it in before submission:
$("#send_email").submit(function() {
$("#content").val($("#windowDesc").html());
}
<script>
var content = $('#windowDesc').html();
$.ajax({
url: 'send_mail.php',
type: 'POST',
data: content
});
</script>
It worked here.
on http://zentili.koding.com i've got this javascript that loads the content of the linked menu item inside the main #content div of the index page, and applies an hash with the name of the loaded page minus the '.php', otherwise it loads the hash + '.php' if it's entered in the url. works very good. On other hand, the ENG/ITA entries add ?locale=lang_LANG inside the url, right before the hash, so that localization is also working fine. If you look well, you may notice that when you switch between ENG and ITA, the index-content appears just for one moment before going to the hash. I know this is because the page is first loaded, then taken to the hash but i was wondering if there some way for hiding the homepage and going directly to the hash location when it's loaded.
Here the code for my menu:
<script type="text/javascript">
$(document).ready(function() {
var hash = window.location.hash.substr(1);
var href = $('#menubar a.item').each(function(){
var href = $(this).attr('href');
if(hash==href.substr(0,href.length-4)){
var toLoad = hash+'.php';
$('#content').load(toLoad);
$("#menubar a.item").removeClass("current");
$(this).addClass("current");
}
});
$('#menubar a.item').click(function(){
window.location.hash = $(this).attr('href').substr(0,$(this).attr('href').length-4);
var toLoad = $(this).attr('href');
$('#content').fadeOut('fast',loadContent);
function loadContent() {
$('#content').load(toLoad,'',showNewContent) }
function showNewContent() {
$('#content').fadeIn('fast'); }
$("#menubar a.item").removeClass("current");
$(this).addClass("current");
return false;
});
});
function goENG(){
var hash = window.location.hash;
var eng = '?locale=en_EN';
window.location.replace(eng+hash) ;
};
function goITA(){
var hash = window.location.hash;
var ita = '?locale=it_IT';
window.location.replace(ita+hash) ;
};
</script>
the functions goENG() and goITA() are called via onclick on the ENG and ITA a's. I hope to find some solution into this.
The page cannot directly go to the link. It will load in its natural order and then it will go to the hash. For what you want to achieve, there is a simple solution i believe.
Hide the main content div until the document loads. use css rule "visibility:hidden" for this
If there is any hash, load it and then make the content visible.
If there is no hash in url, make the content visible on dom load.
$(document).ready(function() {
var hash = window.location.hash.substr(1);
if ($('#menubar a.item').length > 0) {
var href = $('#menubar a.item').each(function(){
var href = $(this).attr('href');
if(hash==href.substr(0,href.length-4)){
var toLoad = hash+'.php';
$('#content').load(toLoad, function(){
$('#content').attr('visibility', 'visible');
});
$("#menubar a.item").removeClass("current");
$(this).addClass("current");
} else {
$('#content').attr('visibility', 'visible');
}
});
} else {
$('#content').attr('visibility', 'visible');
}
});
--UPDATE--
If you are setting #content as "visibility:hidden"
$('#content').attr('visibility', 'visible');
should always fire, else your #content div will be invisible. The trick here is to set it to visible after we are done with checking for hash. You can keep loading the content in the div and make it visible. Making the #content div visible need not be done after entirely loading the hash.
I am experiencing the strangest behaviour on our website, and it is making things incredibly slow.
My team and I have a website running entirely on AJAX. So for the login, I have some js ajax that loads the login box into our index page. The html containing the login box has a script link in the head. This script listens for the login form submission, and sends the form data to the server for authentication through ajax.
The html that contains the login box only gets loaded once, but the js file that it links to gets loaded multiple times. The amount of times change. From 5 times to 15 times and I cannot see a pattern or anything. This happens everywhere on our site, not just at login time.
This issue really has me stumped and I'm totally stuck. Is it because I have ajax in a js file that is loaded in initially with ajax?
I would really appreciate your insight and help!
EDIT:
As requested, some code:
This is a stripped down version of loadContent() in the Interface.js file. This specific function loads all site content into the content area on index.php. When the page is refreshed, the first thing sent to the function is the location of the login.php file, containing the login box:
loadContent: function(page) {
var self = this;
//just some animations to make things look good
$(self.error).fadeOut(150, function() {
$(self.content).fadeOut(150, function() {
$(self.loading).fadeIn(150, function() {
$.ajax({
url: page,
success: function(data) {
//response data
var $response = $(data);
$(self.content_1).html($response);
//definitions for contentbox-2
self.contentHeading_2.html("Replies:");
self.content_2.html(postReplies);
//redisplay the content after it has loaded in.
$(self.loading).fadeOut(150, function() {
$(self.content).fadeIn(150, function() {
// Content faded in
});
});
},
error: function() {
$(self.loading).fadeOut(150, function() {
$(self.error).fadeIn(150, function() {
// Error faded in
});
});
}
});
});
});
});
this.page = page;
}
And then the login.php file:
<!DOCTYPE HTML>
<html>
<head>
<title></title>
<script type="text/javascript" src="js/login.js"></script>
</head>
<body>
<div class="padded loginphp">
<div id="loginbox">
<!-- the login box comes here
</div> <!-- #loginbox -->
</div>
</body>
</html>
And the login.js file:
$(document).ready(function() {
$('#honeyloginform').submit(function(event) {
//event.preventDefault();
login();
return false;
});
});
function login() {
$('.errorinputfields').removeClass('errorinputfields');
if (isEmpty($('#username'))) {
$('#username').addClass('errorinputfields');
$('#username').focus();
return;
}
if (isEmpty($('#password'))) {
$('#password').addClass('errorinputfields');
$('#password').focus();
return;
}
$('#honeyloginform').fadeOut(100, function(){
$('#loginbox .loading').fadeIn(300, function(){
var pword = $('#password').val();
var remember = "no";
if ($('#remember').is(':checked')) {
remember = "yes";
}
var JSONobj = {
username: $('#username').val(),
password: pword,
rem: remember
};
$.ajax({
url: 'ajax/login.php',
data: JSONobj,
success: function(data) {
//alert(data);
var JSONobj = JSON.parse(data);
if (JSONobj.Success) {
Interface.login(); //just loads the landing page after login
//window.setTimeout('location.reload()', 300);
} else {
$('#loginbox .loading').fadeOut(300,function(){
$('#honeyloginform').fadeIn(300);
});
$('#username').focus();
$('#loading-message').text(JSONobj.Message).show();
}
}
});
});
});
}
I've managed to find the problem, and fix it!
I've made a change to my interface layout, and as a result, the three selectors, $(self.error), $(self.content) and $(self.loading) each contain more than one element, where it always only contained one each.
This seems to cause the callback functions to be compounded or something, as everything inside the final callback in loadContent() was called 9 times.
So it was a simple case of redefining the selectors, so that they refer to one element each.
Hey guys. I'm usign a js/ajax script that doesnt work with internet explorer. Firefox its ok.
Btw the head tag, im using this:
$(document).ready(function () {
//Check if url hash value exists (for bookmark)
$.history.init(pageload);
//highlight the selected link
$('a[href=' + document.location.hash + ']').addClass('selected');
//Seearch for link with REL set to ajax
$('a[rel=ajax]').click(function () {
//grab the full url
var hash = this.href;
//remove the # value
hash = hash.replace(/^.*#/, '');
//for back button
$.history.load(hash);
//clear the selected class and add the class class to the selected link
$('a[rel=ajax]').removeClass('selected');
$(this).addClass('selected');
//hide the content and show the progress bar
$('#content').hide();
$('#loading').show();
//run the ajax
getPage();
//cancel the anchor tag behaviour
return false;
});
});
function pageload(hash) {
//if hash value exists, run the ajax
if (hash) getPage();
}
function getPage() {
//generate the parameter for the php script
var data = 'page=' + encodeURIComponent(document.location.hash);
$.ajax({
url: "http://pathfofolder/js/loader.php",
type: "GET",
data: data,
cache: false,
success: function (html) {
//hide the progress bar
$('#loading').hide();
//add the content retrieved from ajax and put it in the #content div
$('#content').html(html);
//display the body with fadeIn transition
$('#content').fadeIn('slow');
}
});
}
The loader.php contain the php code to get pages, something like:
switch($_GET['page']) {
case '#link1' : $page = 'contenthere'; break;
}
echo $page;
So, on the links, i'm using Link 1 to load the content into the div content.
The script does works well with firefox, but with internet explorer it doesnt load the content. Could someone pls help me to fix this?
It not go into the success function at all on IE, and i'm getting no html error from IE too.
Best Regards.
Make sure your html is sounds. FF tends to auto fix the syntax.
