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);
});

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
I want to use content(some div) on the page.
So I request the the page using AJAX. Since I want to use some div (by ID), I have written the following code but the problem is the HTML that gets returned from the delete1.aspx is faulty so I can not convert it to XML
$('#one').click(function () {
$.ajax({
url: 'http://localhost:51967/delete1.aspx',
success: function (data, status, xhr) {
var temp = $.parseXML(data);
$('#arjunvachhani').html($(temp).find('#id1').html());
}
});
});
I have tried to put it on some hidden div so that browser will correct it and then retrieve that div, but in that case, the browser will request css and js and some other images which is changing appearance of my page(where I put the retrieved HTML). It is also very slow
One more problem "I can't change the delete1.aspx file"
If it's valid HTML, but not valid XML, try:
var temp = $('<div/>', { html: data });
$('#arjunvachhani').html(temp.find('#id1').html());
I'm always having trouble with that,
i'm loading a file with AJAX :
$.ajax({
url: fullHref,
success : function(result) {
console.log(fullHref+" was loaded via AJAX");
saveImages(result);
}
});
and trying to iterate through all images in result :
function saveImages(file){
console.log("savesImages enterd");
$(file).find('img').each(function(){
console.log("The file has this image : "+$(this).attr('src'));
});
}
}
I've also tried :
$('img',file)
$('img',$(file))
$('img',$(file).html())
Yet it doesn't enter the loop.
Any suggestions?
I'm using Chrome, and i don't wanna use regex.
Tryfilter() instead of find:
$(file).filter('img').each(function() { /* ... */ });
find() looks down the DOM tree which is not what you want if the img elements in the string are all at the root level.
Just make a new node and set the innerHTML of it.
$('<span></span>').html(file).find('img').each(...
$.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.
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,
