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

jquery .load() does not load external JS

I am loading external content into a div element using jquery.load() without a selector. If the content loaded has embedded JS, the JS works as expected. HOWEVER, if the content includes a script tag with src=path-to-js-code the js-code is not loaded.
Am I correct in this observation and if so is there a good solution other than embedding the JS in the loaded content?
EDIT :
A few clarifications and observations:
To load the content I am using
$("#DivId").load("path/to/content.php", CallbackFunction(response, status, xhr) {
error checking and post processing code
});
Changing the load code to:
$.get("path/to/content.php", CallbackFunction(response, status, xhr) {
error checking
$("#DivId").html(response);
post processing
});
Does not seem to change the behavior (more on the behavior below)
I have not tried parsing the response to retreive the script src and then using getScript().
Now more on the behavior...
Using Firefox, it seems that the external JS is loaded but only if it has been about 2 min from the last load. I do not see an attempt in Firebug unless the refresh is about 2m after the last load of the external JS. (weird). When I was making JS code changes and hitting refresh, it was not loading my new code and thus the original question.
So i will withdraw my question in light of this clarified behavior (2m caching?).
Thanks.

Both the .load() and .html() jQuery methods utilise the .innerHTML property. This won't execute scripts added with <script> tag. Use a regular AJAX call e.g. .get() then in the callback use .append() to add your HTML string and the scripts will run once it's parsed e.g.
$.get("path/to/content.php", function(response, status, xhr) {
// error checking
$("#DivId").append(response); // Any <script> tags in the response string will execute
// post processing
});
Thing is you need to make sure you're running trusted code if it's added by .append()

I was wondering you can get the script src in the response text of $.load method with regular expressions, then use $.getScript() method to load the script, maybe something like this:
$("#DivId").load("path/to/content.php", function(response, status, xhr) {
var regexp = new RegExp('script.*?src="(.*?)"'),
execresults = regexp.exec(response);
if(execresults.length > 1)
{
// the first result is the entire match including
// the 'script..src=', so abandon it
var matches = execresults.slice(1);
$.each(matches, function(){
$.getScript(this, function(){
// do something after load script
});
});
}
});
Hope this can help

This is the easy way to load an external JS to your jQuery
$.ajax({
type: "GET",
url: "path/to/content.php",
dataType: "script"
success:CallbackFunction(response, status, xhr)
});

Error with find() after correct result

I have some errors in my extension. I have this code that do a find() on an external page:
$.ajax({
url: 'http://www.subspedia.tv/traduzioni.php',
success: function(data) {
$(data).find('.itemListaSerie').each(function() {
console.log($(this).attr('title'));
});
}
});
The find function work correctly but after the result I have a lot of errors that say "File not found" on all images in the page that I'm doing the request.
The screen show my result:

You need to post process the relate links like immagini/serie/covers/33.png for each of the images, and convert them into something like
http://www.subspedia.tv/immagini/serie/covers/33.png
instead of using it as is
EDIT:
The images loaded are probably due to the $(data). If you need only the titles, then you should replace the src of all the tags before $(data)
success: function(data) {
var strippedData = data.replace(/src='(?:[^'\/]*\/)*([^']+)'/g, "");
$(strippedData).find('.itemListaSerie').each(function() {
console.log($(this).attr('title'));
});
Credit to #Gumbo for his answer on regex for matching src. Note, this will remove all src attributes in the page

After your success function, using $(data) you create an element that contain all the html from http://www.subspedia.tv/traduzioni.php so, the document is looking for all the script, css and the images included in that page.
try to replace all the img as words in data as string and then call $(data).find....
Hope this helps you! Anche se mi sarei spiegato meglio in Italiano ;)

Get HTML source code as a string

I want the source code of an HTML page (1.html) to be used in another page (2.html). Furthermore, I want to perform operations on it in 2.html.
Is there a way to do this?
EDIT: 1.html is a separate public webpage and I do not have access to make changes to its source code. I have to do whatever I need only by using 2.html.

To get the DOM converted to a string:
document.getElementsByTagName('html')[0].innerHTML
Question: what do you mean by "use it"? Do you need to include 1.html inside 2.html? Or do you just need to process it?

Its very simple
On 2.html use this jQuery snippet
$.get("1.html", function(response) {
alert(response)
//do you operations
});

jQuery:
$.get('ajax/test.html', function(data) {
$('.result').html(data);
alert('Load was performed.');
});

I don't understand whatyou mean that you must make modifications, but you could simply load the second page through AJAX
var url ="1.html";
$.ajax({
url: url,
dataType: 'html'
success: function(data){
//do something with data, which is the page 1.html
}
});

Use can use .html method alternatively to get the entire html data of the page.
$(function(){
var a = ($('html').html())
})​

A realy simple and modern way is the follow:
fetch('1.html').then(function(response) {
/* when the page is loaded convert it to plain text */
return response.text()
}).then(function(html) {
/* initialize the DOM parser */
var initParser = new DOMParser();
/* parse the text */
var parse = initParser.parseFromString(html, 'text/html');
/* you can now even select part of that html as you would in the regular DOM */
/* example */
var docOutput = parse.querySelector('html').outerHTML;
console.log(docOutput);
}).catch(function(error) {
console.log('Error fetch page: ', error);
});

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,
