load div content from external file - php

I've tried several options to try and load the content from a div on one page with id="container" into a div on a different html page id="landing".
I used the answer here and also lots of variations of it
Load content of a div on another page
I've run a test and Jquery is being loaded.
The test files are here http://www.salcombeyurts.co.uk/test/landing.html
My code looks like this:
<script type="text/javascript">
$('#landing').load('source.html #container');
</script>
This will eventually end up on a PHP page. Part of a Joomla site.

You run the script before the #landing div is defined.
Run your code after the DOM ready event
$(function(){
$('#landing').load('source.html #container');
});

It seems like the suggestion you got was to do an AJAX request and load the entire page into the #container div on the current page, which is not a bad idea. What you seem to be trying to do, on the other hand, is load the page and then get the content of a div inside that page and put it in a container div on the current page, which is overly complicated and a bad solution to what ever the problem is.
Here is my solution none the less
$(function() {
$.get('page with the div you want', function(data) {
var content = $(data); //turn the page into a jquery object
var div = content.find('#div'); // this is the div you want the content from
$('#container').html(div.html()); // this will set the content of the current div
});
});

I would move your script to the bottom of the page and replace it like so.
Original:
<script type="text/javascript">
$('#landing').load('source.html #container');
</script>
New:
<script type="text/javascript">
$(document).ready(function() {
$('#landing').load('source.html #container');
});
</script>
Note the space removal between source.html and #container.

jQuery's GET is acting up for me. Using CodeIgniter. It returns source code for a view instead of one value

I am trying to test the jQuery GET method, but what I am getting as result is completely insane. All I am trying to do is call a function from my controller with jQuery and then display the echoed value in a div within my view. Below is my code and finally a breakdown of the problem I am encountering.
Controller
public function generate_suggestions2() {
echo "James";
}
View views\suggestions_v.php
<body>
//This DIV is used a button to call the jQuery function
<div id="next_btn">
<p>Click here to display a name</p>
</div>
//In this div the value retrieved by the jQuery should be displayed
<div id="listB"></div>
//This is the function that calls the function within my controller
<script type="text/javascript">
$( "#next_btn" ).click(function() {
$.get("core/generate_suggestions2/",
function(data) {
$( "#listB" ).html(data);
});
});
</script> //For some reason I need to put the script at the end of the body. When it's in the head nothing happens when I click the button. Also something I do not understand.
</body>
Now the problem is that when I click the DIV next_btn it does NOT display the James in the DIV listB.
Instead it populates the DIV listB with my source code from my main view views\core_v.php
I have no idea how this is even remotely possible, so please if you have a clue or even better you know what I am doing wrong please tell me. I am trying to get this to work for the past three days without any success or progress :(
Try using this code in your view
<script type="text/javascript">
"$( "#next_btn" ).click(function() {
$.get("<?php echo site_url().'/core/generate_suggestions2';?>",
function(data) {
$( "#listB" ).html(data);
});
});"
</script>
Also delete the </script> tag just right before this block comment.
Regarding this comment you have:
//For some reason I need to put the script at the end of the body. When it's in the head nothing happens when I click the button. Also something I do not understand.
It is because the DOM is not yet fully loaded and Javascript executes its code when the browser has finished loading the DOM you are referring to. So you either have to put it after the DOM element you want to edit, like you do now or you could use $(document).ready(function(){
}
); .

This line is pretty strange:
</script><script type="text/javascript">
Try to delete first closing tag 'script' on it.

Jquery: Building navigation including page inside body

I builded for my home page (index.php) a navigation bar, where I can click on one of the available links (anchors). Selecting one link a new body is loaded inside my page (index.php) that contains this code:
<script type="text/javascript">
$(document).ready(function(){
$('#myselector a').click(function(e) {
var url = $(this).attr('href');
$('#body').load(url);
e.preventDefault();
});
});
this works good.
But, now after loading new page page1.php inside the body of index.php I have this trouble:
My page1.php contains a form, and after the submission I need to reload the index.php with page2.php inside. How can I perfrom this?
Note: I edit my question: If you think that now it is clear can you upvote plese? (I was banned for this question and I can't post other question)
In order to catch events from nodes inserted at a later point you need to use event-delegation, for example like this:
$("body").on("click", "a", function(e){
var url = $(this).attr('href');
e.preventDefault();
$('#body').load(url);
});
This way every click on a link, which is a childnode of body will cause the eventhandler to fire. If you do not want to target all links, but just specific ones you can do that by adding a class to them and the selector.

Javascript within AJAX loaded pages

I have a main (index) page which loads pages dynamically and places them inside it's div but the Javascript within those pages doesn't execute. Specifically this part
<script type="text/javascript">
$(document).ready(function(){
$('#regForm').submit(function(e) {
register();
e.preventDefault();
});
});
</script>
You will have to use getScript like this:
$('#foo').load('bar.html', function(){
$.getScript("js/fileName.js");
// call a function from fileName.js
});
You will have to put your JS code in that file and call that via getScript and then you can call functions from it as shown above.
Write your javascript in the index.php or write at the bottom of loaded page without document.ready
This is in reality a cross-browser issue: When <div>s are dynamically filled with HTML containing <script> tags, these scripts may or may not run - and this behaviour is different not only between browsers, but also between browser versions.
The only workaround I know of is to extract your JS, send it seperately and execute it after the <div> content has been set.

JavaScript problem

I am building a website that uses PHP and JavaScript. I have a main menu that dynamically, when I click on a button it loads a page in the content div and runs its JavaScript script.
Now the problem is when I have loaded a JavaScript file and I go to another page that loads its contents in the same content div, the old JavaScript file that was included in the previous page is still loaded. Is there a way to prevent this.
JavaScript code:
$(".button").click(function(){
$("#content").empty();
$("#content").load("PHP/home.php");
});
PHP/home.php code
<html>
<head>
<title>test</title>
<script type="text/javascript">
$(document).ready(run);
function run(){
alert("test");
setTimeout(run, 500);
}
</script>
</head>
<body>
<h1>Homepage</h1>
</body>
the Jquery is loaded in the HTML that the content div is. And all the other buttons and PHP pages is being used the same way. When i load a new page the Alert function of the home.php is still going.
just have a clue because you haven't shown enough code
try clearing out the div with
document.getElementById("content").innerHMTL = "";
then adding other page content in it

Best way of loading external page with AJAX

I'm not brilliant with AJAX but could somebody please write me a quick code for switching a DIV tag with an external page.
For example:
<script type="text/javascript">
// Fun Stuff Here //
</script>
<div id="random">HIDDEN</div>
It would be AWESOME if the content could fade-in when it's loaded.
Ok, I have this so far (but it doesn't seem to be working):
<ul>
<li>ss3</li>
<li>ss4</li>
</ul>
<script type="text/javascript">
$(function(){
$("a.load").click(function (e) {
e.preventDefault();
$("#folioWrap").load($(this).attr("href"));
});
});
</script>
<div id="folioWrap"></div>
You may want to try this JavaScript AJAX loader jQuery plugin that can load page elements content via AJAX and it alters all the links in such way that when you click on the links of the AJAX loaded content, the new page element content is also loaded via AJAX.
I suppose you can hack it to add any fade transition effects when the new page element is loaded.
