I'm just starting to playing around on a Mac for the first time and I have created a very simple HTML page that uses jQuery to do a simple text swap when an h1 tag is clicked.
When I don't view the page through the webserver and just open it directly in Safari (file:///Applications/xampp/xamppfiles/htdocs/test/mypage.html) it works as expected. However, when I try to view through Apache (http://localhost/test/mypage.html) it doesn't work.
Here's the code:
<html>
<head>
<title>My Awesome Page</title>
<script type="text/javascript" src="jquery.js"></script>
<script type="text/javascript" charset="utf-8">
function sayHello()
{ $('#foo').text('Hi there!');
}
</script>
</head>
<body>
<h1 id="foo" onclick="sayHello()">Click me!</h1>
</body>
</html>
Am I missing something on the Mac? Wouldn't be an Apache setting since its client-side code.. right?
I should probably also mention that I loaded XAMPP to run Apache and MySQL. I have tested Apache to ensure its working using a simple PHP file.

Use Firebug and access the page. One things that might be a culprit is that the web server cannot open jquery.js file because of file permission. Firebug will show if the jquery loaded in page, even you can add the jQuery code on-the-fly in the Console tab.
If you access it using Safari, use Web Inspector and see the if any error showed in Console tab.
One last thing, make a habit to avoid onclick, do this instead:
<script type="text/javascript" charset="utf-8">
function sayHello()
{
$('#foo').text('Hi there!');
}
//wait DOM loaded
jQuery(function($){
$('#foo').click(function(){
sayHello();
});
});
</script>
Also, it's better to put the js code near the page end, before </body>, so it would not block concurrent page element's loading.

I swear I've copied and pasted 100 different things that should work, but nothing is working.
I have my main html document, test.html:
<html>
<head>
</head>
<body>
<header></header>
<div class='content'>some content</div>
<script src='https://cdnjs.cloudflare.com/ajax/libs/jquery/3.5.1/jquery.min.js' type='text/javascript'></script>
<script src="script.js"></script>
</body>
</html>
Another html document, test2.html:
<p>this should show up if it works</p>
And a javascript document, script.js:
$(function() {
$("header").load("test2.html");
});
My end goal is to get a navbar.html document that can be referenced via jquery by multiple different html documents. Here, I'm trying to do a verrrrrrry simple test to get the .load() function to work.
When I load test.html, I expect to see the text from both test.html and test2.html, but I'm not seeing the text from test2.html. What am I doing wrong here?
For this kind of request, you need to be running on a server as you will get an CORS (Cross Origin Ressource Sharing) if running the file directly from your html file. You could use Live Server on Visual Studio code or directly on an apache server to run your perticular code.
You can also see this link if my first answer doesn't work https://medium.com/#dtkatz/3-ways-to-fix-the-cors-error-and-how-access-control-allow-origin-works-d97d55946d9
I am at the start of learning Javascript, but within the first 10min I hit on a Chrome issue. I'm attempting to display the code I wrote with Visual Studio in the Chrome console, but rather than showing the code in the section below the menus 'Element', 'Console', 'Source' etc, the code displays exactly as I wrote it, but in the view panel including all html tags below the menu section 'Apps', 'Bookmarks', 'Customize Links' etc. How do I resolve this, any answers?
I tried to use ctrl-o to open the .js file whilst in Visual Studio and also whilst on Chrome, but only the file path to the .js file opened, and when subsequently clicking on the file it looked like the image below.
chrome not displaying JavaScript code in the location I want it to be
To clarify - you are loading a .js file in the browser which is what is displaying in chrome (the content of that file).
What you want to do is run that js file and have Chrome's JavaScript interpreter (V8) parse that information. To do that, you must add your script to an index.html page and then in index.html, load that e.g something like <script type="text/javascript" src="script.js"></script>
Alternatively, you can just run the JavaScript directly in index.html via
<script type="text/javascript">
// your JavaScript
</script>
You are opening the javascript file directly in the browser, not opening an .html file with a javascript tag. That's why Chrome is showing you the file content.
If you want to execute your javascript code in the Chrome console, paste it directly in the "console" tab of the developer tools.
If you want to execute your javascript code in a web page, you have to create an html file with a script tag loading your javascript code, something like:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<script src="main.js"></script>
</head>
<body>
</body>
</html>
In order to see your html content on browser you should load .html file instead of loading .js file
you can include your javascript code in two ways
Add your Javascript code inside the script tagcreate a new javascript file with extension .js and add it in your html file
Example1 (Adding Javascript inside script tag)
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<script>
console.log("good morning");
alert("good morning");
</script>
</body>
</html>
Example2 (Adding Javascript from external file)
<!DOCTYPE html>
<html>
<head>
</head>
<body>
<script src="nameOfFile.js"></script>
</body>
</html>
I am using a local HTML file with link to an external script (located in the same directory) that worked when in the file, but externally doesn't. Neither Firefox nor Chrome. Code:
<html>
<head>
<script type="text/javascript" src="docket.js"> </script>
</head>
<body onload="doFunction()"> ...
The script is in a .js file, which has (simplified):
function doFunction() ....
For one, you shouldn't include the script tags in your external js file.
Also try to move the script line at the bottom before the closing body tag.
If after removing, it still doesn't work, you should open the developer tools to get clue of what is going on.
index.html:
<!DOCTYPE html>
<head>
...
</head>
<body onload="doFunction()">
...
<script type="text/javascript" src="docket.js"></script>
</body>
</html>
docket.js:
function doFunction() {
alert("hello...");
}
Note: no script tags
As per w3school - https://www.w3schools.com/tags/tag_script.asp
The external script file cannot contain the tag.
The syntax for script tag is -
<script src="URL">
Where your URL is -
1. An absolute URL - points to another web site (like src="http://www.example.com/example.js") OR
2. A relative URL - points to a file within a web site (like src="/scripts/example.js")
Note: with HTML5, type attribute for script tag is optional.
I'd suggest to add a noscript tag just to make sure you have JS enabled in your browser.
<noscript>Your browser does not support JavaScript!</noscript>
I'm very new to html and trying to make a website. So far, I've got an html file that has the header for my site and I would like to use it in all the pages I create for the site using jQuery's load function.
So basically what I want to do is load Header.html into Page.html.
This is the code in Page.html:
<html lang="en" xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta charset="utf-8" />
<title>Hello</title>
<script type="text/javascript" src="jQuery.js"></script>
<script type="text/javascript">
$(document).ready(function () {
$("#Header").load("Header.html");
});
</script>
</head>
<body>
Hi
<div id="Header"></div>
</body>
</html>
Header.html looks something like this:
<div id="Header_Name">Adabelle Combrink</div>
<div id="Header_GameProgrammer">Game Programmer</div>
The only thing that comes up on the screen is "Hi" at the moment.
Looks good, apart from the backslashes in the src attributes should be forward slashes.
Is there any particular error you are getting?
Also, as has been pointed out, PHP would be better suited to this job.
<?php include 'header.php'; ?>
Aside from the accessibility question, there might also be a negative SEO impact.
Edit:
Assuming your path to jQuery is correct, then the code you posted should work (it does for me).
Things to try / be sure of:
You are running this on a server (i.e. not just opening the file in your browser, as this will fall foul of the same origin policy). Check that the address in your address bar doesn't start with file://
Make sure that the path to the jQuery library is correct
Make sure that Page.html and Header.html are in the same folder
Check your broswer's error console. Instructions.
you can use iframe for including html file into the div.
Otherwise you have to follow some server side include method.
like, in php <?php include("includes/header.php"); ?>
your code looks fine.
are you running the site on a web server, such as out of visual studio (iis express) ?
You can't run it locally. Ajax wont work that way.
Open your page in chrome, and press f12 to open up dev tools.
go to the network tab.
do you see the ajax request being fired on the load function?
by the way, regarding the header div,
a div is not a self-closing tag. Its a container. Its best that you close it using a closing tag.
Otherwise you might get unpredictable results in some browsers. ( I have not checked in a while, but it was that way a few years ago, probably in explorer 8)
jQuery(document).ready(function(){
jQuery.ajax({
url: 'header.html',
type: 'get',
success:function(data){
jQuery('#header_container').html(data);
}
});
});
<div id="header_container">....</div>
The content returned by the request will go inside the header_container div
Div elements require a closing div tag like so <div></div>.
there is no need to call small pieces of code from another js file, just write your code in the head element like so:
<!doctype html>
<html>
<head>
<meta charset="utf-8" />
<title>Hello</title>
<script type="text/javascript" src="../Scripts/jQuery.js"></script>
<script>
$(document).ready(function() {
$("#Header").load("../Templates/Header.html");
});
</script>
</head>
<body>
<div id="Header"></div>
</body>
</html>
Don't be afraid to ask for more info.
$.load() http://api.jquery.com/load/
I am trying to create a small, simple JS framework for education purposes, but now I've got a problem I'm unable to solve.
Directory structure
/
/framework
jquery.js
init.js
/content
home.html
style.css
index.html
The problem
I'm obviously not pasting the jQuery file and stylesheet here, but here are index.html and init.js:
index.html
<!DOCTYPE html>
<head>
<script src="framework/jquery-1.5.min.js"></script>
<script src="framework/init.js"></script>
<title>My website</title>
</head>
<body>
<div id="content">
</div>
</body>
</html>
init.js
$(document).ready(function(){
if(!window.location.hash) {
$("#content").load("../content/home.html", function() {
alert("Load was performed.");
});
}
});
The home.html file contains some sample text, nothing special. I expect jQuery to load the contents of home.html into the content div, but nothing happens when I load the page. The alert with the message "Load was performed" is fired, however.
This task seems quite trivial to me so the mistake I made is probably quite silly, but any help is nevertheless very much appreciated.
Thank you!
Update:
It works when I use this on my server, but in localhost it fails. I can't use the Firebug trick now, because it shows nothing when I use it locally.. Any ideas?
The load function is broken in jquery 1.5 release. You can find the bug ticket at http://bugs.jquery.com/ticket/8125. This is fixed in version 1.5.1 which is not yet released to google and microsoft cdn. You can find the very latest jquery release with all the latest fixes including load() at http://code.jquery.com/jquery-git.js
I tested and confirmed that your code works in 1.5.1
If you're using Firebug, open the NET tab. It allows you to see the ajax response.
Chances are you should be using: /content/home.html, not ../content/home.html
The path is in context to the page, not where the JS file resides.
The base location for the executing script is the location of index.html, so the relative path to home.html is "content/home.html", and not "../content/home.html".
just try it with ./
$(document).ready(function(){
if(!window.location.hash) {
$("#content").load("./content/home.html", function() {
alert("Load was performed.");
});
}
});
that is working for me at least.
