What is the correct syntax for adding an external reference to a JavaScript file (.js) within another JavaScript file?
There isn't any.
You can add a <script> block to the document, but it will execute asynchronously.
Alternatively store all your .js files in a php file.
<script src="js.php" type="text/javascript"></script>
php:
<?php
require 'js/myjs1.js';
require 'js/myjs2.js';
?>
I suppose you could load content of file via ajax and use eval().

I have a PHP script that includes a .JS file. The PHP file makes a jquery call to an external functions.php file which requires the same .JS file, however, with it being a separate file, I have to include it again inside functions.php. If I do this, it breaks the first include, but the 2nd include works. If I remove the include from the external file, the script doesn't work, but everything in the original file does.
Is there a way to include a JS file in the external file without calling it again? Can it just call from the first include?
Included as:
<script type="text/javascript" src="js/scripts.min.js"></script>
Using php's include_once
should resolve your problem. This function ensures that the given file will only be included once.
I want to use jquery in my web application. Should I include it as a link in my external JavaScript file or inside my html file?
Thanks in advance
No. The way to include a javascript file is using <script src="file.js"></script>
The contents of file.js should not be surrounded with <script> tags as that is html code.
Yea sorry i was mistaken, didn't think external javascript counts but apperantly it does.
<script src="myScript.js"> code in here </script>
I have two JavaScript files in a web application project and want a function in one file to call a function from the other. How can that be done?
Refer to both files from the HTML page
<script src="js/file1.js"></script>
<script src="js/file2.js"></script>
functions in one file should be accessible from functions in another file.
When both JS files are parsed by a browser functions from one file will be visible to another and vice versa.
Please bear in mind that the JavaScript file which should be used in another JavaScript file usually needs to be declared before the other JavaScript file (using the HTML <script> tag).
I am making a website using PHP. I have various Javascript snippets in various pages and various Javascript files. I want to put them all in one .js file. How can I do that?
Copy them all into one file, in the order they were included within document.
If they were written correctly, there should be no problems. But there may be problems regarding some conflicts (like names of the variables) or cases, when the script was not meant to be executed on all pages (eg. assumes some container exists within HTML, but this container is only on some pages - thus on other pages the script may throw some errors or behave inappropriately).
With PHP you could just make a faux-javascript file, e.g. js.php and then include all the js files like:
<?php
include('foo.js');
include('bar.js');
Then reference this file from the main php page's html:
<script type="text/javascript" src="js.php"></script>
Another way is by inline js as
<script type="text/javascript">
<?php
include "one.js";
include "two.js";
?>
</script>
I also try to reduce js, css and use image sprite for background to reduce browser header requests.
I have a javascript file main.js and five html files 1.html,2.html,3.html,4.html,5.html
I want to access the javascript file main.as in all files .
I have used in all of the five but I'm not able to access it . Is it possible to share the .js file among the html files.
Plz reply,
Thanks in advance

Yes, it is entirely possible. That's the point of being able to have a JS file instead of having to embed all the code in the HTML.
yes this is well possible. You merely have to include
<script type="text/javascript" src="main.js"></script>
in your HTML files, preferably near the bottom (for faster rendering). What have you done so far?
Yes. Totally possible.
Just reference it in all of the files e.g. by
<script type="text/javascript" src="Scripts/main.js"></script>
Yes, it is possible.
Probably there is something wrong with the way you access the javascript from your html. Show us the <script ...>...</script> part of your html.
Yes. Are you using the correct path to the main.js file in your html files?
Create separate javascript file with .js extension with all your function in it and
just include this javascript file in the head tag of all the html scripts u wanna use that in.
Like::
<html>
<head>
<script type="text/javascript" src="JavaScriptFilePath.js"></script>
</head>
<body>
<!-- use javascript -->
It can happen both ways..
a single html file can use multiple javascript file
2.a javascript file can be used in several html files.
In first case javascript file load can be conditional based on location, user preferences, time, age group, content restriction.
You can see good example when facebook loads its page. I loads number of javascritps.
