AJAX Post HTML Code

I'm having an issue with sending some HTML code using AJAX please see my code below
<iframe src="http://www.w3schools.com" width="10" height="10" id="awc_frame"></iframe>
<script>var iframe = document.getElementById("awc_frame");</script>
Here is the AJAX code below
<script>
$.ajax({
type: "POST",
url: "mobileView.php",
data: { val : iframe },
success: function(data){
console.log(data);
}
})
</script>
The code isn't sending the variable to the PHP file. Looking into the Network side of things it sends text ie if I put "" around iframe it sends this code
"val = iframe" but not the actual code within the iframe. The "var iframe"does work and pulls back the HTML code of the iframe
Please tell me what I'm doing wrongly.
Thanks in advance.
EDIT: I'm sorry. It's not the HTML code within the iFrame I need to send, It's the entire iFrame code I need to send.
Another Edit: What I'm trying to accomplish when a visitor from my company goes to my website I would like Javascript or Jquery to load an internal website from the visitors computer and then have all of the code from that website that's on the client's end to be sent to a Server which will store the entire iFrame code in a database.

This would send the entire html inside the iframe.
var iframe = $('#awc_frame').html();

First of all, var iframe does not contain HTML of the iframe element - it contains a DOM Node, which is kind of a wrapper around the iframe element (it contains various properties of that element, including the HTML).
Next thing, you probably want to wait for the iframe to completely load all the contents, so you'll have to bind to the load event of it.
Something like this should work:
var $iframe = $("#awc_frame");
$iframe.on("load", function () {
var iframeHTML = $iframe[0].contentWindow.document.body.innerHTML;
// jQuery alternative
var iframeHTML = $iframe.contents().find("body").html();
$.ajax({
type: "POST",
url: "mobileView.php",
data: {
val: iframeHTML
},
success: function(data){
console.log(data);
}
});
});
Super important thing in this example
Just one more thing - please note that for websites outside of your own domain, this code won't work (due to Same Origin Policy). Any other code won't work too.

Since javascript has problems with getting the HTML from a cross-domain iframe, you can't do this across domains. However, why not just send the iframe's src attribute to the PHP page, and then just use file_get_contents to get the HTML, and then store that? Problem solved:
Javascript:
var iframe = $('#awc_frame').prop('src');
$.ajax({
type: "POST",
url: "posttest.php",
data: { val : iframe },
success: function(data){
console.log(data);
}
});
PHP:
$html = file_get_contents($_POST['val']);

what are you trying to do?
var iframe = document.getElementById("awc_frame");
above code is an javascript object of your iframe which contains a lot of properties.. since you are using jQuery, you could get that with:
var iframe = $('#awc_frame');
keep in mind that above code is the element it self in jquery object format you could get element object like this:
var iframe = $('#awc_frame')[0];
** you're doing something wrong.
if you're trying to get iframe HTML content:
var iframe_contents = $("#awc_frame").contents();
if you explain more about what you are trying to do, i can update my answer to suit you.
* UPDATE *
considering what you are trying to do..
Method #1: (Easy Way)
you could use php to fetch content of the website you need:
<?php
$contents = file_get_contents('http://www.w3schools.com');
// Saving $contents to database...
?>
Method #2: (Hard Way)
as #mdziekon said, you first should wait until your iframe gets loaded then:
var iframe = $("#awc_frame");
iframe.on("load", function () {
var contents = $(this)[0].innerHTML;
$.ajax({
type: "POST",
url: "mobileView.php",
data: {
val: contents
},
success: function(data){
console.log(data);
}
});
});
hope it solves your problem

Why .html() method does not load data in the element?

$.get("progress.txt", null, function(data_aj){
if(data_aj.substr(0,14) == "<!-- MSG:: -->"){
$("#list").html("<li>"+data_aj+"</li>");
window.clearTimeout(timeOutId);
}else{
$("#list").html(data_aj);
}
});
I really have tried everything but can't figure out whats wrong. If I use alert(data_aj); it gives the desired output and just works fine but HTML(data_aj) just doesnt loads into a <ul> element #list using .html(). Can anyone tell me why?

Have you tried putting your code in a document ready, as your alert will fire fine but if your dom is not loaded then you cannot append to it. Also use .append() for lists not html
$(document).ready(function() {
$.get("progress.txt", null, function(data_aj){
if(data_aj.substr(0,14) == "<!-- MSG:: -->"){
$("#list").append("<li>"+data_aj+"</li>");
window.clearTimeout(timeOutId);
}else{
$("#list").append(data_aj);
}
});
});

Listen up...
$.get() is a shorthand for $.ajax().
So when you do this
$.get(uri, function(data){
//Your functionality
});
You're really doing this
$.ajax({
url: uri,
type: "GET",
success: function(data) {
//Your functionality
}
});
By default this returns the page as HTML. Or rather, by default, it first checks the MIME-type on the page, and if none is found, it returns HTML. As you are requesting a .txt file it will interpret it as a simple textfile. If you want to tell it what you would like to return (HTML), you can either do it in the MIME-type on the server page, or you could use $.getJSON().
An easy way to solve this is thus doing:
$.get(uri, function(data) {
//Your functionality
},
"html");
Which is the same as doing:
$.ajax({
url: uri,
type: "GET",
dataType: "HTML",
success: function(data) {
//Your functionality
}
});
Also it is not a good idea to use html() because you are replacing the existing html inside of your ul element every time you want to add an additional new node.
Try making use of:
$('#list').append('<li>' + data_aj + '</li>');
Basically you can just append the <li> to the <ul> itself.
Lastly make sure your dom has already been loaded by placing all your JQuery code into the
$(document).ready(function() {
//Your code...
});
Otherwise if your HTML is not fully loaded yet, your list might not exist yet so there is no way for JQuery to put some values into unexisting HTML.

Jquery masonary formatting changes after ajax update

I'm using the masonary jquery plugin to format images loaded into my page via ajax.
It's all working perfectly except for when images are loaded in through ajax, they seem to gain extra margin/padding values from nowhere and do not fit seamlessly like the images already on the page. I've tried adding margin:0; padding:0; but nothing seems to work
All my code is currently live here:
http://1hype.me/
Any ideas are greatly appreciated!
EDIT:
The problem is occurring on everything i've tested, Safari, Chrome & FF (mac)
Here's a screenshot that explains it a bit more: http://cl.ly/0d0q37290W1r0j0X2g0c

This is due to whitespace.
You could just return the image from the ajax call (without any script)
and just run
function fetch() {
//autoupdater
$.ajax({
type: "POST",
url: "ajax/fetch_image.php",
cache: false,
data: "after=000000",
success: function(results){
var imgHolder = $('#image_holder');
/* prepend the results
results is just the image (without whitespace around it) */
imgHolder.prepend(results);
/* fade in the first image (the one we just prepended)*/
imgHolder.find('img:first').fadeIn(1100);
/* do the masonry thing.. */
imgHolder.masonry({ singleMode: true });
}
});
}
if that is not an option (altering the fetch_image.php) then you can use
function fetch() {
//autoupdater
$.ajax({
type: "POST",
url: "ajax/fetch_image.php",
cache: false,
data: "after=000000",
success: function(results){
var imgHolder = $('#image_holder');
/* exclude text whitespace nodes (not included in a tag).*/
var $results = $(results).filter(function(){return this.nodeType != 3});
imgHolder.prepend( $results.eq(0) );
$('body').append( $results.eq(1) );
}
});
}

Embedding Javascript in html document

I'm trying to implement the following code in a html document:
$(function () {
$.ajax({
type: "GET",
url: "/projects/img/Bathurst/PhotoGallery.xml", // location of your gallery's xml file
dataType: "xml",
success: function(xml) {
$(xml).find('img').each(function() {
var location = '/projects/img/Bathurst/'; // relative path to the directory that holds your images
var url = $(this).attr('src');
var alt = $(this).attr('alt');
$('<li></li>').html('<img class="thumb" src="'+location+''+url+'" alt="'+alt+'" title="'+alt+'" />').appendTo('#gallery-ul');
});
$('<script type="text/javascript"></script>').html('Shadowbox.clearCache(); Shadowbox.setup();').appendTo('#photo-gallery');
}
});
});
The code works perfectly when I use it in an external .js file, but I cant get it working when i implement it, it just renders with error in the code.
II'm I missing something and dos anyone have a suggestion to this? The reason why I need to implement it, in case some one wonderes, is that I'm building a custom webapp and the line "/projects/img/Bathurst/PhotoGallery.xml" and "/projects/img/Bathurst/" is dynamic variables.
All answers are very much appreciated! :)

The problematic line ($('<script type="text/javascript">...) is a convluted and unnecessarily complicated way to run two lines of Javascript.
You should replace it with simple method calls. (Shadowbox.clearCache(); Shadowbox.setup();)

You can't have a </script> inside a script.
Change
$('<script type="text/javascript"></script>')
to
$('<script type="text/javascript"><\/script>')

JQuery Treeview not working with Ajax

I'm new to JQuery and web development in general. I'm trying to load some data from an XML file and build an unordered list. I've got that part working, now I'm trying to use the TreeView plugin so I can collapse/expand the data. The data is loaded like this:
$(document).ready(function(){
$.ajax({
type: "GET",
url: "solutions.xml",
dataType: ($.browser.msie) ? "text" : "xml",
success: function(data) {
var xml;
if (typeof data == "string") {
// Work around IE6 lameness
xml = new ActiveXObject("Microsoft.XMLDOM");
xml.async = false;
xml.loadXML(data);
} else {
xml = data;
}
list = ""
$(xml).find("Group").each(function() {
group = $(this).attr("name");
list += "<li><span>" + group + "</span><ul>";
$(this).find("Solution").each(function() {
solution = $(this).attr("name");
list += "<li><span>" + solution + "</span></li>";
});
list += "</ul></li>";
});
$("#groups").html(list);
},
error: function(x) {
alert("Error processing solutions.xml.");
}
});
$("#groups").treeview({
toggle: function() {
console.log("%s was toggled.", $(this).find(">span").text());
}
});
});
and the HTML looks like this:
<html>
...
<body>
<ul id="groups">
</ul>
</body>
</html>
The unordered list shows correctly, but the little [+] and [-] signs don't show up and the sections aren't collapsible/expandable. If I get rid of my Ajax loading and insert an unordered list inside of #groups manually it works as expected.
What am I doing wrong? Is there any other plugins or Javascript libs that could make this easier? The solution needs to work on IE6 locally (i.e. webserver).
Update: I found a work-around: If I define my treeview stuff like this it works:
function makeTreeview() {
$("#container").treeview({
toggle: function() {
console.log("%s was toggled.", $(this).find(">span").text());
}
});
}
setTimeout('makeTreeview();', 50);
I think the problem is, when I create the treeview, the ajax stuff hasn't done it's work yet, so when treeview() is called, the unordered list hasn't been created yet. I haven't tested this with IE6 yet. Is there a nicer way to do this, without using SetTimeout()?

I made the same type of call for another project.
For other reasons you will probably want to wrap your ajax call in an anonymous function to create a closure so that your variables remain what you expect them to...
The success method is a callback function that happens after your call is complete , just create your treeview inside that method, or break it out into a seperate fumction if you need to for clarity.
in the example that you show - your treeview will still fail if the ajax call takes longer than 50ms - which could easily happen during initial load if more than two objects are being loaded from that same server.
This example used JSON, and concurrently loaded html data from a page method into a series of divs.
$(document).ready(function() {
for (i= 1;i<=4;i++)
{
(function (){
var divname ="#queuediv"+i;
$.ajax({
type: "POST",
contentType: "application/json; charset=utf-8",
dataType: "json",
url: "test12.aspx/GetHtmlTest",
data: "{}",
error: function(xhr, status, error) {
alert("AJAX Error!");
},
success: function(msg) {
$(divname).removeClass('isequeue_updating');
$(divname).html(msg);
$("#somethingfromthemsg").treeview();
}
});
})();
}
});
Hope that helps!

You need to get FireBug (Firefox add-in) and then you can see in the console what is being returned, and make sure it matches what you expect (And that it is actually doing the request..).
Once you get it working in FF, you can support the ancient 10-year old IE6 browser.
There's also some other things you may want to consider:
The whole ActiveXObject("Microsoft.XMLDOM") jumps out as me as unnecessary. If you pass XML in a string to $(), jQuery turns it into a DOM object.
Additionally, .Find can be replaced by:
$('Element', this);
So for example:
var xmlDoc = '<Group><Solution name="foo" /><Solution name="bar" /></Group>';
$('Solution', xmlDoc).each(function() {
document.write( $(this).attr('name') );
});
would spit out:
foo
bar
Also, with firebug, stick a console.log(list); at the end, to be sure you're generating the HTML you think you are. If you're really stuck in IE6, alert(list) somewhat works as a poor man's equivalent (as long as your file isn't too big).
In short, I think you're on the right track, you just need the tools to debug properly.

For anyone who also finds their way to this post. I had this trouble with an ajax call.
If you want to wait for the ajax call to be returned, you need to set async as false.
$.ajax({
type: 'POST',
async: false,
