Do I have to setup a javascript file like an html file so it can display the text i put in the
document.write("hello world!");
I have the <script> </script> inside the html but it still won't display the text i ask for
This is working for me.
<script>document.write("helloWorld")</script>
if you want to use javascript you have to put the actual js code into the script tag or link to an external script file.
It is recommended to set up the external file >like your html file< and to link to it inside of an <script> tag at the bottom of the html document. The filename could be App.js and you would have to link to it like this html <script src="./App.js"></script> (if the file is in the same folder).

Here is the code - https://www.w3schools.com/howto/howto_js_accordion.asp.
I can setup just fine in a single HTML file, but I want to move the JS code to an external file.
I make the JS code in the external file a function and an "onclick" attribute, it has to be double-clicked as an external file, don't know how to fix this? Thanks.
So I have a website, https://coolkids.gq. I want to be able to add a certain line of code to every single HTML file on the website using another HTML, JavaScript or PHP file, but I am not sure how to do this.
How would I be able to write a script to add a line of custom code to every HTML page on my website?
Edit: As pointed out by charlieftl, I should clarify that all files are saved in either the /htdocs folder or in a folder inside of that.
yes you can, just make some folder named include or whatever and create for example loginForm.html sth like
<div>
<form>
....
</form>
</div>
and in pages where you want to put it use
<?php require('./include/loginForm.html') ?>; in place where you need it
Of course it need to be PHP page.
Good thing is to have also included header and footer in external html and include it on every php page ;D
if you want some js script in every page you need to add it manualy:
<script src="js/main.js"></script>
but it can be included in footer.
<!-- Custom JavaScript file -->
<scrpit src="./js/main.js"></scrpit>
If I press control+click on this src name, i go successfully to javascript file that i want to activate (which should mean that I have wrote the file's name and place well enough), but when i open the html page the functions in the script do not work.
To check if the problem is within the js code, i went and copied the js code inside the the html file, which worked properly.
But why wouldnt it work when i put it in a separate js file and call the file in the manner above?
I think there is a typo in your code.
Your code:
<scrpit src="./js/main.js"></scrpit>
Try to use this:
<script src="./js/main.js"></script>
I have an HTML file, parent.html which has a link to a javascript file code.js with a whole lot of functionality in it.
The HTML file parent.html also loads another HTML page using the <object>tag.
This file is called child.html. It makes reference to the code which is in code.js. It calls a function when a button is clicked in the child.html file.
I keep getting an "Uncaught ReferenceError".
How can I fix this issue?
I thought that because my js file was added to the parent level file, that it would be accessible to the children files.
we can link a CSS file in HTML file. But how can I link JavaScript file in an html file?
Suppose if we link a CSS file we write
Like that how can I link a JavaScript file?
Use a <script> tag.
<script src="/some/server/resource.js"></script>
Note that the type attribute is no longer necessary. You used to write it as:
<script type="text/javascript" src="/a/b/c.js"></script>
Bear in mind that where you put the <script> tag can impact how the JavaScript behaves as it can block the DOM while loading if added to the <head>. The differences about what placement changes what is an entirely different question.
you can link a javascript file in a HTML document using the script tag.
Here is an example:
<script src="myscripts.js"></script>
Here is some more information about this: http://www.w3schools.com/tags/att_script_src.asp
You can also write javascript inside script tags like normal.
Add a <script src="url_to_your_script.js"></script> tag to your html file, preferably in the head tag.
For more information, visit https://developer.mozilla.org/en-US/docs/Web/HTML/Element/script
<script src="your_file_name.js"></script>
Add this code at the end of your body tag.
Happy Coding:)
