I have an HTML page that calls a JS file. Within that JS file I need to know what the URL of the HTML page is.
So far I have this.
HTML -
<!doctype html>
<html>
<head>
<title>Untitled</title>
</head>
<body>
<script src="js/jquery.js"></script>
<script src="js/main.js"></script>
</body>
</html>
Within my main.js I have the following:
$(function() {
$ = jQuery;
window.remoteUser = "%globals_server_REMOTE_USER%";
window.targetURL = "%globals_asset_url%";
console.log(document.referrer);
});
I thought document.referrer would return the URL of the html page. However it returns a blank line in the console.
Any help would be great. Thanks
Try this,
console.log(document.URL);
OR
console.log(window.location.href);
since i read that it doesn't work in some versions of firefox
location.href used to get url the of page.
jQuery(document).ready(function(){
jQuery("#url1").html(location.href);
});

I am trying to make a very simple thing work:
<!DOCTYPE html>
<html lang="en">
<head>
</head>
<body>
<script src="js/test.js" type="text/js"></script>
<button onclick="test()" type="submit">Test</button>
</body>
</html>
With js/test.js being found by the browser and containing:
function test() {
alert("test");
}
When opening the page and clicking the button, nothing happens and I can see in the console:
Uncaught ReferenceError: test is not defined
at HTMLButtonElement.onclick (test:7)
I have tried to move the script import above or under the button, or in the header.
I have tried to use "window.setlocale = function" in my js file.
I have tried to put nothing in the test method.
I checked for errors with JSLint (there is no error).
When I check the source, I can see the js file and the browser opens it when I click on it.
The only way I can get the Javascript to work is to write it inline...
Maybe the issue is with my environment?
In order to run this, I use an Apache server, and it is configured to serve this on localhost:8077. I works fine so far.
I use Laravel 7.10, PHP 7.4... working fine. To run this I created a simple route, that shows the view (a simple index.blade.php) with the HTML content copy/pasted above. It displays fine on "http://localhost:8077/test", no problem.
I also tried to use the laravel notation
<script src="{{ asset('js/test.js') }}" type="text/js"></script>
but it gives the same result.
I also have the PHP debugbar (a Laravel plugin) active, and it does not show any error. The view is properly loaded and displayed.
Also, I use PHPStorm, and it does not detect any issue.
It's been 2 days and I cannot makes this seemingly extremely basic thing to work, please help me m(_ _)m
Your script type is wrong. Use application/javascript in your script element to make your javascript work - or better yet, remove the type attribute and let browsers auto-detect the type:
<!DOCTYPE html>
<html lang="en">
<head>
</head>
<body>
<script src="js/test.js" type="application/javascript"></script>
<button onclick="test()" type="submit">Test</button>
</body>
</html>
Without type attribute:
<!DOCTYPE html>
<html lang="en">
<head>
</head>
<body>
<script src="js/test.js"></script>
<button onclick="test()" type="submit">Test</button>
</body>
</html>
you can try to add script tag to header tag. like this
<head>
<script type="text/javascript" src="path/to/script.js"></script>
<!--other script and also external css included over here-->
</head>
Try removing the function name in js/test.js
function() {
alert("test");
}
Please add the js file as a reference in the header section of your core file. External referencing.
I'm trying to load a .txt file into my simple html page. I'm very noobish and all the code i got is stolen from stackoverflow.
The text file is in the same folder as the html file and contains some text that I'd like to have shown in a div and not just loaded in at the start but dynamically updated (in a 1 sec interval).
The Page that results from the code is just empty.
I am using Chrome 73.
I only use the html file and the txt file. No other files are in the folder.
<html>
<head>
<script type="text/javascript">
setInterval(read,1000);
function read(){
jQuery.get('file.txt',function(data){$('#container').html(data);});
}
read();
</script>
</head>
<body>
<div id="container"></div>
</body>
</html>
I don't know what's wrong with this code. Am I missing libraries? If you came up with a completely new code that would be appreciated as well.
Yes, you are missing the jQuery library. Try it like this and let me know:
<html>
<head>
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/2.2.4/jquery.min.js"></script>
<script type="text/javascript">
function read(){
jQuery.get('file.txt',function(data){$('#container').html(data);});
setTimeout(function(){read() },1000);
}
read();
</script>
</head>
<body>
<div id="container"></div>
</body>
</html>

See note in italics at very bottom of this article
what about a simple jQuery Load ?
$("#container").load("file.txt");
http://api.jquery.com/load/
I am creating a website, I am using a NodeJS server. In my public folder I have a script named website.js and it has the jQuery code to give a console.log when the h1 is clicked. (Code Below). But when I click on the h1 in the browser it does not work. The file is loaded properly, gives no 404 error and my CSS stylesheet works fine.
Further Testing: I did a simple test to see if it would give back the text when I called the variable (test code below) it responds with: "" (two quotation marks) so it must not be recognizing it.
//Test code
var xyz = $("#testh1").text();
//jQuery Code
$("#testh1").on("click", function(){
console.log("Clicked");
});
<!DOCTYPE html>
<html>
<head>
<script type="text/javascript" src="/javascripts/website.js"></script>
<link rel="stylesheet" type="text/css" href="/stylesheets/website.css">
<script src="https://code.jquery.com/jquery-2.2.4.js" integrity="sha256-iT6Q9iMJYuQiMWNd9lDyBUStIq/8PuOW33aOqmvFpqI=" crossorigin="anonymous"></script>
<title>test</title>
</head>
<body>
<h1 id="testh1">TEST</h1>
</body>
</html>
You need to load jQuery before your script.
<script src="https://path-to-jquery"></script>
<script src="/javascripts/website.js"></script>
You need to wait for the DOM to be ready before accessing any elements in it. You can either do it with the following code:
$(document).ready(function() {
$("#testh1").on("click", function(){
console.log("Clicked");
});
});
or by putting your <script>s at the bottom of the <body> instead of in the <head>.
<script src="https://path-to-jquery"></script>
<script src="/javascripts/website.js"></script>
</body>
You're getting an empty string in your test code because your #testh1 element hasn't been loaded yet.
Scenario: You have a script that users can place on their website and when they click on it, it redirects to my website then calls a function only after they have successfully been redirected to my website and the function is part of my website, so there shouldn't be any problem with the same origin security policy.
So is the scenario possible?
EDIT
Ok now that I know that it can be done, I run into a pickle doing this.
function main(){
$(document).ready(function($){
window.location.href = 'http://www.example.com/michael';
theclient.chat();
});
}
I want theclient.chat() to be called after example.com/michael is loaded but it's not working.
UPDATE 2
function main(){
window.location.href = 'http://www.reflap.com/michaelnana';
$(document).ready(function(){
theclient.chat();
});
}
So will this work?
You have to call that function on your own site in the following block:
Source page:
function main(){
window.location.href = 'http://www.example.com/michael';
}
Target page (http://www.example.com/michael):
$(document).ready(function(){
theclient.chat();
});
To be clear: this will be called, if you type the URL of the page too and not only after a redirect.
You should add a URL parameter when you do the redirect, if you want to call it only after a redirect.
UPDATE:
You cannot call a function on the original page, after the redirect has been done.
On your target page, if you include the jQuery library, use this code:
$(document).ready(function(){
theclient.chat();
});
The ready() method makes sure the page (http://www.reflap.com/michaelnana) is rendered before running your JavaScript.
I've included 3 sample files that should serve as a skeleton for what you're trying to do.
www.external-site.com/index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8"/>
<title>3rd Party Page</title>
</head>
<body>
<script type="text/javascript"
src="http://www.example.com/michael/embed.js">
</script>
</body>
</html>
www.example.com/michael/embed.js
// load jQuery, keep it in our scope
// I'll not explain how this works but if you're making an embed
// script for other sites, you must make sure to encapsulate all
// your dependencies such as jQuery.
loadDependencies(function($) {
// document onload
$(function() {
// create a button that redirects to example.com/michael
var button = $('<a>').text('click me').click(function() {
window.location.href = 'http://www.example.com/micahel';
});
// insert that button after this script tag
var src = 'http://www.example.com/michael/embjed.js';
$('script[src="' + src + '"]').after(button);
});
});
www.example.com/michael/index.html
<!DOCTYPE html>
<html lang="en">

<title>Landing Page</title>

<script type="text/javascript" src="theClient.js"></script>
<script type="text/javascript">
$(function() {
// all visitors to this page will trigger this call, not just
// the ones who came from the script embed. If you want to
// differentiate I'd recommened adding a query paremeter to
// the redirect and reading it there.
theClient.chat();
});
</script>

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..
