i write me jquery script in html page like this:
<script> function pofileEditable(){
var pFormEditable = $('#profi-form input');
$('#pBtnSave').removeAttr('disabled', '');
$('#pBtnEdit').attr('disabled', 'disabled');
$('#prof-form-anrede').removeAttr('disabled', '');
} </script>
How can I write it in separate file ex like that test.js
and import it?
<script type="text/javascript" src="js/test.js"></script>
I don't wont to use javascript method
var edit = document.getElementById("pBtnEdit");
Best practice is to include your js file at the end of the HTML body tag, like this.
<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<body>
<!-- your content here -->
<!-- If you want to use JQuery, load it before your js file here -->
<!-- your own js file -->
<script src = 'path/to-your-js-file/your-js-file.js'></script>
</body>
</html>
You just import jquery first and then import your own script:
<script src="jquery-1.6.1.js"></script>
<script src="my_jquery.js"></script>

How do you properly link a JavaScript file to a HTML document?
Secondly, how do you use jQuery within a JavaScript file?
First you need to download JQuery library from http://jquery.com/ then
load the jquery library the following way within your html head tags
then you can test whether the jquery is working by coding your jquery code after the jquery loading script
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<!--LINK JQUERY-->
<script type="text/javascript" src="jquery-3.3.1.js"></script>
<!--PERSONAL SCRIPT JavaScript-->
<script type="text/javascript">
$(function(){
alert("My First Jquery Test");
});
</script>
</head>
<body><!-- Your web--></body>
</html>
If you want to use your jquery scripts file seperately you must define the external .js file this way after the jquery library loading.
<script type="text/javascript" src="jquery-3.3.1.js"></script>
<script src="js/YourExternalJQueryScripts.js"></script>
Test in real time
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<!--LINK JQUERY-->
<script type="text/javascript" src="jquery-3.3.1.js"></script>
<!--PERSONAL SCRIPT JavaScript-->
<script type="text/javascript">
$(function(){
alert("My First Jquery Test");
});
</script>
</head>
<body><!-- Your web--></body>
</html>
This is how you link a JS file in HTML
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script> - tag is used to define a client-side script, such as a JavaScript.
type - specify the type of the script
src - script file name and path
To include an external Javascript file you use the <script> tag. The src attribute points to the location of your Javascript file within your web project.
<script src="some.js" type="text/javascript"></script>
JQuery is simply a Javascript file, so if you download a copy of the file you can include it within your page using a script tag. You can also include Jquery from a content distribution network such as the one hosted by Google.
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
You can add script tags in your HTML document, ideally inside the which points to your javascript files. Order of the script tags are important. Load the jQuery before your script files if you want to use jQuery from your script.
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
<script type="text/javascript" src="relative/path/to/your/javascript.js"></script>
Then in your javascript file you can refer to jQuery either using $ sign or jQuery.
Example:
jQuery.each(arr, function(i) { console.log(i); });
Below you have some VALID html5 example document. The type attribute in script tag is not mandatory in HTML5.
You use jquery by $ charater. Put libraries (like jquery) in <head> tag - but your script put allways at the bottom of document (<body> tag) - due this you will be sure that all libraries and html document will be loaded when your script execution starts. You can also use src attribute in bottom script tag to include you script file instead of putting direct js code like above.
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Example</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>
</head>
<body>
<div>Im the content</div>
<script>
alert( $('div').text() ); // show message with div content
</script>
</body>
</html>
this is demo code but it will help
<!DOCTYPE html>
<html>
<head>
<title>APITABLE 3</title>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>

$(document).ready(function(){
$.ajax({
type: "GET",
url: "https://reqres.in/api/users/",
data: '$format=json',
dataType: 'json',
success: function (data) {
$.each(data.data,function(d,results){
console.log(data);
$("#apiData").append(
"<tr>"

})
}
});
});
</script>

I'm trying to work with three.js and really just html and js in general for the first time. I'm playing around with the example code and I found that even if I import the three.js file from the script tag in my Main.js file, it doesn't work unless I uncomment the script tag currently commented out. Why is this the case? Is there anyway i can run it in just my Main.js file without the first script tag?
<!DOCTYPE html>
<html>
<head>
<!-- <meta charset="utf-8"> -->
<title>My first three.js app</title>
<style>
body { margin: 0; }
</style>
</head>
<body>
<!-- <script src="node_modules\three\build\three.js"></script> -->
<script src="js/Main.js"></script>
</body>
</html>
please try this option: in your main html page <script type="module" src="js/Main.js"></script> and in your main.js page import other js pages
Try replacing
<script src="node_module/three/build/three.js"></script>
with
<script type="module" src="node_module/three/build/three.module.js"></script>
If you are importing module functions, it should be declared as a module.
(Not sure why type="module" should be part of the tag
<script src="js/Main.js"></script>
unless Main.js is exporting functions to be used outside of it.)
I have one file, that is external from my index.html page, named code.js with this code on it:
function parse() {
if (a === 1)
alert("a equals 1");
}
(function() {
parse();
})();
As I said, that file is called code.js.
Now, I have an index.html file that is in the same folder/directory as the code.js file. Now, this is my index.html:
<!DOCTYPE html>
<html>
<head>
<title>Javascript</title>
<link rel="stylesheet" type="text/css" href="style.css" />
<script src="code.js"></script>
<script type="text/javascript">
var a = 1;
</script>
</head>
<body>
<h1>Javascript</h1>
</body>
</html>
So I want to be able for the code.js file to use the variable from my javascript that is in the index.html file. I am doing this because I am going to make my own javascript library, but I need to do learn this first. Any solutions?
Switch the order of your script tags:
<script type="text/javascript">
var a = 1;
</script>
<script src="code.js"></script>
This way, the global variable a will be initialized before the parse method in code.js is called.
To add on to what Robby said, browsers load a page in order from top to bottom, left to right, because that is how they are written (sort of). This means in your supplied code, code.js is loaded and run before you set a=1. As Robby mentioned, you can easily switch the order of your <script> tags and be fine.
This applies to other elements as well, so any other elements will not be accessible before their place in the HTML document. For example, a <div> in the body cannot be referenced by code run in the head, because the body has not been loaded yet. You can circumvent this by adding a <script> tag at the end of your HTML document, to be run after the main document has been loaded, but not necessarily all other external data like images (external scripts should be fine, however). The snippet below is what I have found works best:
<!DOCTYPE html>
<html>
<head>
<title>Javascript</title>
<link rel="stylesheet" type="text/css" href="style.css" />
<!-- Any script here could be anywhere (embedded/external) and in any order -->
<script>
function ready() {
document.getElementById('a').textContent = 'a = ' + a;
}
</script>
<script type="text/javascript">
var a = 1;
</script>
<!-- <script src="code.js"></script> - load external code here -->
</head>
<body>
<h1>Javascript</h1>
<div id="a">a = ?</div>
<script>ready(); // Runs code after document is initialized</script>
</body>
</html>
I know by include <script type="text/javascript" src="scripts/jquery-1.10.2.js"></script> in HTML file, I can write in jQuery in this file directly. However, I am not working on a single file, thus, too much js code in the html doesn't look good. Can there be some method to use jQuery in js file? So I can put some common function in a standalone js file.
You can put your code in your own js file :
$(function() {
// your own code using the DOM
});
and then include this file just after the jQuery one :
<script src="scripts/jquery-1.10.2.js"></script>
<script src="myownfile.js"></script>
create a folder with the name js and inside put your js file for example main.js
your js file should start like : main.js
$(document).ready(function(){
//code here
});
note that you can use $(document).load(function() too
In your index.html put this in the footer like this : index.html
<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Your Website</title>
</head>
<body>
<!--============MAIN-CONTAINER============ -->
<section>
</section>
<!--============SIDEBAR=================== -->
<aside>
</aside>
<!--============FOOTER==================== -->
<footer>
<script src="http://code.jquery.com/jquery-2.0.0.min.js"></script>
<script src="js/main.js"></script>
</footer>
</body>
</html>
for the best performance.
alfernative
if you want to use it as
<script src="scripts/jquery-2.0.0.min.js"></script>
download this:
http://code.jquery.com/jquery-2.0.0.min.js
and put it into a new folder with the name scripts and replace
<script src="http://code.jquery.com/jquery-2.0.0.min.js"></script>
with
<script src="scripts/jquery-2.0.0.min.js"></script>
in your footer like this:
<footer>
<script src="scripts/jquery-2.0.0.min.js"></script>
<script src="js/main.js"></script>
</footer>
Of course you can use an external .js file, just add the required scripts files and their references onto your page plus add the external .js reference along with them.
//references in mail file
<script src="../Scripts/jquery-1.7.js" type="text/javascript"></script>
<script src="../Scripts/jquery-1.7.min.js" type="text/javascript"></script>
<script src="../Scripts/text.js" type="text/javascript"></script>
//External test.js file
$(document).ready(function () {
//your functions here
}); // Document Ready Closed
Just keep that tag for jquery and go ahead and make your own JS file with jquery code in it and include that too in the html page, It will work
In the javascript assets file I have a jstester.js file like this:
function hehe()
{
alert("wedsdsd");
}
document.write("fdygsdfysdgf");
Then in the public index.html file I have this:
<!DOCTYPE html>
<html>
<head>
<title></title>
</head>
<body>
<script src="/assets/jstester.js">
hehe();
</script>
</body>
</html>
So I thought that is how I can call a method from my Javascript file but looks like it is not working, no message box shows up... So what is the correct way of doing this?
If a <script> has a src then the text content of the element will be ignored.
so you can't do:
<script type="text/javascript" src="assets/jstester.js">
hehe();
</script>
but:
<script type="text/javascript" src="assets/jstester.js"></script>
<script>hehe();</script>
This is what you looking for:
<body>
<script src="/assets/jstester.js"></script>
<script type="text/javascript">hehe();</script>
</body>
