I am trying to create a webpage including an iframe where the iframe has customizable content. Its an API project.
My main issue is not how to manage appending content to an iframe using jQuery, but in this case I have an empty iframe where I want to insert a full webpage into it. The code for the webpage going into the iframe is received using a .post function where I in return get the full webpage in the data variable.
I can't manage to insert the full code, which include local javascript with important javascript libraries. It is as if it doesn't execute the code inside the iframe. The code is inserted but all the main html/body etc tags are deleted from the code passed in data variable, which prevents various javascript code from working.
I have of course checked that the page received in data variable is ALL of the code. It is correct. The missing tags are missing when displayed in the iframe.
(parent page, domain unknown to me as a API provider)
<body>
<iframe id="EMSNLframe" srcdoc="" seamless></iframe>
<script>
$("#EMSNLframe").load(function(){
$.post("https://api.educationalmedia.se/API_displayNTNewsLetterMenu",
{
ResUID:"[secret code]",
MenuLanguage:"English",
PDFLanguage:"" // Blank for all languages, or state a language
},
function(data,status){
$("#EMSNLframe").contents().find("html").html(data); //<---- this is the line I need a solution for! If there is any.
});
$("#EMSNLframe").contents().find("head").append($("<style> #EMSNLmenu{font-family:'Arial',sans-serif;font-size:12px} </style>"));
});
</script>
</body>
Webpage received in data variable:
<!DOCTYPE html>
<html>
<head>

I'm trying to achieve the following:
A simple Java Spring application, after receiving a GET request, sends me an HTML page with a form. When the button is pressed in this form, there is a POST request with an XML content sent back to the Spring app, which, in turn, responds with an HTML page. I would like to be able to display this response as a proper page in a browser, including all the scripts being downloaded and fully functional.
The form HTML page:
<!DOCTYPE html>
<html lang="en">
<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>
<meta charset="UTF-8" />
<title>Request Report Form</title>
</head>
<body>
<form method="post" action="">
<script>
function sendXml()
{
event.preventDefault();
const request = '<?xml version="1.0" encoding="UTF-8"?>\n' +
<!-- skip -->
$.ajax({
type: 'POST',
url: url,
dataType: 'html',
data: request,
contentType: 'application/xml;'
}).done(function (data) {
$("html").html(data);
}).fail(function (data) {
$("html").html(data.responseText);
});
}
</script>
</form>
</body>
</html>
The $("html").html(data); part above is supposed to replace the current page's content with the content received from the server, as far as I understand. But the page is not being displayed. There is an error message in the browser's console: "TypeError: n.head is null", it seems to have to do with JQuery, see the image link.
My questions are, why does JQuery kicks in and what is it trying to do? And how do I fix this error?
I don't know much about frontend side of development, so please go easy on me ;-)
Edit
Just realised that my first question is moot, I am trying to display the response page using JQuery, so obviously, it kicks in at that point. But the call fails for some reason.
The content of the response from the server that I'd like to see rendered by the browser:
<!DOCTYPE html>

}

Found an answer here: stackoverflow.com/a/11984907/3182810. Replacing
$("html").html(data);
in the form with
document.open();
document.write(data);
document.close();
does the trick.
I think this might be the code I require, but how do I integrate it into my page code, should it be in Head/Body/ /etc.???
Your help would be appreciated!
Many Thanks
if($.cookie('popup') != 'seen'){
$.cookie('popup', 'seen', { expires: 365, path: '/' }); // Set it to last a year, for example.
$j("#popup").delay(2000).fadeIn();
$j('#popup-close').click(function(e) // You are clicking the close button
{
$j('#popup').fadeOut(); // Now the pop up is hiden.
});
$j('#popup').click(function(e)
{
$j('#popup').fadeOut();
});
};
Put it in a script block inside your head tag. Don't forget to include any libraries you need.
<html>
<head>
<script src="https://code.jquery.com/jquery-3.1.1.min.js"></script>
<script src = "any other library you need"></script>
<script>
if($.cookie('popup') != 'seen'){
$.cookie('popup', 'seen', { expires: 365, path: '/' }); // Set it to last a year, for example.
$j("#popup").delay(2000).fadeIn();
$j('#popup-close').click(function(e) // You are clicking the close button
{
$j('#popup').fadeOut(); // Now the pop up is hiden.
});
$j('#popup').click(function(e)
{
$j('#popup').fadeOut();
});
};
</script>
</head>
<body>
your html here
<some_element_with id="popup" />
</body>
</html>
Best practice for importing scripts in your html is at the end of your body, right before the closing </body> tag so they load after the content does. The main reasons behind this are:
Scripts block parallel downloads. The HTTP/1.1 specification suggests that browsers download no more than two components in parallel per hostname.
The content your user can see should be loaded first, then the utility you provide with scripts.
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width">
<title>JS Bin</title>
<!-- CSS should be imported here -->
</head>
<body>
<!-- JS scripts should go here (libraries first) -->
</body>
</html>
For more information you can visit this question:
Where is the best place to put script tags in HTML markup?
I know this shall be a very silly question but some years have passed since the last time I developed some javascript.
I'd like to brush on that and so I decided to learn some Dojo.
The problem is that I can't manage to get this simple Dijit example working
As far far as I understand it should produce a button with a Click Me label but the only thing I get is an empty button. It seems the script is not executed. What am I doing wrong?
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Test Dijit</title>
<!-- load Dojo -->
<link rel="stylesheet" href="//ajax.googleapis.com/ajax/libs/dojo/1.8.1/dijit/themes/claro/claro.css">
<script src="//ajax.googleapis.com/ajax/libs/dojo/1.8.1/dojo/dojo.js" data-dojo-config="isDebug: true, async: true, parseOnLoad: true"></script>
</head>
<body class="claro">
<button id="btn"></button>
<script>
require(["dijit/form/Button", "dojo/domReady!"], function(Button) {
var button = new Button({
label: "Click Me!",
onClick: function(){ console.log("First button was clicked!"); }
}, "btn");
button.startup();
});
</script>
</body>
</html>
If you're loading the page using a file:// URL (or double-clicking the file), it won't work due to the schema-less URI's you're using to load the stylesheet and dojo.
Try adding the protocol "http" before the leading pair of slashes in the respective link & script tags.
See also Can I change all my http:// links to just //?
I was wondering, how I get the content of a loaded script, stylesheet, ... bye an accessing an id set on the element.
Example:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Demo</title>
<script src="../jquery-1.8.3.min.js"></script>
<script id="test" src="test.txt" type="text/isis-template"></script>
<!-- File contains "Hello world" -->
<script>
$(function () {
$('#test').GET_CONTENT_OF_LOADED_FILE
});
</script>
</head>
<body>
</body>
</html>
Background: I want to load HTML templates (e.g. for mustach, knockout), but don't want to write them into the page, I'd rather have them in a seperate file. Now I saw that I can load any file with the script or link tag, so I was testing if I can load them like this....
Any comments why this might be a bad idea or how it can be done better are appreciated.
Try using load()
$(function () {
$('#test').load('yourfolder/test.html', function(resp){
alert(resp);
});
});
If you have already load the contents in some html element
contents = $('#test').html();
So you want the content of text/isis-template file when document is ready?
You are lucky because this file doesn't fall for CORS but mine(the answer i was looking for and came here today) do.
Well just do ajax!
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Demo</title>
<script src="../jquery-1.8.3.min.js"></script>
<!-- File contains "Hello world" -->
<script>
$(function () {
$.ajax({ url: "test.html"})
.done(function(cont) {
var GET_CONTENT_OF_LOADED_FILE=cont;
});
});
</script>
</head>
<body></body>
</html>
If you use debug tools and see the network activity, you will see that it does not load the external files (since it is not a text/javascript, and the browser does not know how to handle it)
(wrong test on my part, was testing local files)
So you only have a tag there with an id and an external resource in the src attribute. Treat it as just metadata.
You will have to manually load the resources
something like this
// load external template resources
$('script[type="text/isis-template"]').each(function(){
$(this).load(this.src);
});
For actual use you would need to make sure the templates are loaded before you try using them..
I am no web designer pro so please be gentle
Situation:
I am currently building a website to be able to share my DJ mixes and studio production work, a preview is available on http://davidloran.com/test-03/index.html .
The site is composed of:
index.html
-> contains:
1- A css3 menu (including list of mixes currently being correctly played in the player)
2- A jquery plugin audio player (http://codecanyon.net/item/fullwidth...-plugin/841563)
3- An IFRAME where the other pages are loaded into
tracks.html
-> contains a list of the production tracks to be selected by the user and then (eventually!) played into the player placed on the index page
facebook.html
-> contains FB comments box
background.html
Problem found:
As you probably noticed from my description text above, the production tracks cannot be played in the audio-player because they are placed in another page (track.html) called into the IFRAME.
Question:
Are there any ways the audio-player .js code (I'll post the code in next) can be modified so that it handles play requests initialised from pages within the iframe?
Any other suggestions come to minds? (remote window? other?)
Thank you!
this what I've got on the index.html page head:

//set here the swf folder
soundManager.url = 'swf/';
//need to be flash player 9
soundManager.flashVersion = 9;
//prefer HTML5 audio rather than flash
soundManager.useHTML5Audio = true;
$(document).ready(function(){
$('#fap').fullwidthAudioPlayer({autoPlay: 'true', wrapperPosition:'bottom', wrapperColor:'#3f3f3f'});
});
function changeContent() {
document.getElementById('tracks').innerHTML="";
}
</script>
</head>
where, from the same page, links like this one play correctly in the player:
<ul class="fap-my-playlist">
<li>Lounge session - Bar</li>
The question is: How do I get the same types of links work from a different page opening within an IFRAME?!?
You can indeed make something happen in one frame when something happens in another frame using JavaScript. Use the parent object from within the frame. Look here for some examples: http://www.pageresource.com/jscript/jframe1.htm
Also, you mentioned in passing that you might want to do it from another window, as well. This can be accomplished using window.opener.
