How to use Javascript file as a resources file - javascript

I'm trying to make a Javascript a key value object and use it as my Resources for localization
I have made this Jascsript code in a javascript file:
var Values = {
lbl_CustomerName:"Customer name: "
}
now need to use this object in my HTML file:
<title>Title</title>
<script src="../content/JS/Resources/en-us/Resources.js"></script>
</head>
<body>
Values.lbl_CustomerName
</body>
</html>
but it's parsed as a plane text!
I need to call this Object and access the key to show it's value in my HTML file how to do this?

we can truly advice you to use a javascript framework like angular js that embed this kind of behavior inside the framework.
without javascript framework, you will need to modify the DOM by yourself to insert your expected value. If you want to do it in pure javascript function you can write a functio like :
function insertKey(elem,id) {
elem.innerHTML = Values[id];
}
In your case it will look like that :
<title>Title</title>
<script src="../content/JS/Resources/en-us/Resources.js"></script>
<script type="text/javascript">
function insertKey(elem,id) {
elem.innerHTML = Values[id];
}
</script>
</head>
<body>
<div onload="insertKey(this,'lbl_CustomerName')"></div>
</body>
</html>

Whenever you want to parse a JavaScript code, you should wrap it inside a script tag.
<title>Title</title>
<script src="../content/JS/Resources/en-us/Resources.js"></script>
</head>
<body>
<script> document.write(Values.lbl_CustomerName); </script>
</body>
</html>
Browsers have interpreters and virtual machines. Natively, they parse the codes as HTML. if you need to use other syntaxes like CSS and JavaScript, you should tell them hey browser, parse this section as a CSS, JavaScript.
That's why we need and tags

I got the answer, the Javascript file must return an object, so I can use it on my page as follows:
javascript:
function resourcesObject() {
return {
"customerName": "Customer name";
};
}
HTML
<script>
var resources=resourcesObject();
var customerName=resources["customerName"];
</script>

what is the correct HTL syntax for get the custom attribute in AEM global request object?

I want get the custom attribute in AEM HTL use the request object. this attribute already set to request through javascript use API. like this:
test.js
use(function () {
request.setAttribute('someKey', 'someValue');
});
test.html
<html data-sly-use.logic="test.js">
<!-- some code ... -->
<body>
<div>${request.attribute['someKey']}</div>
</body>
</html>
result:
<html data-sly-use.logic="test.js">
<!-- some code ... -->
<body>
<div></div> <!-- empty -->
</body>
</html>
We can get request attribute without Java? Many thanks.
Since HTL syntax is rather declarative than imperative, calling methods/functions with parameters is not supported. That means you cannot do something like ${request.getAttribute('someKey')}. Unfortunately, the Java HttpServletRequest API does not expose the attributes as a map (it does that for parameters) so you cannot do ${request.attributeMap['someKey']} either, you'll need to fetch the attribute and expose it from your use-object/model.
Though you cannot send request attribute the way you are trying to do right now , you can set that as a variable from your server side JS and access it in your code.
In your test.js
use(function () {
return {
someKey: someValue
};
});
In your test.html
<html data-sly-use.logic="test.js">
<!-- some code ... -->
<body>
<div>${logic.someKey}</div>
</body>
</html>
This should print the someValue as output for you.

Move javascript files into inline html

I have an application that allows the use of inline javascript, but not javascript from source files. I'm trying to modify a webpage to open on this browser, and need to know how to put the javascript files from the webpage inline.
Use <script> tags in your HTML. They can go anywhere - I prefer inside the <head> tag:
<head>
<script type="text/javascript">
// put anything here - any type of valid javascript works
// if you import jquery, you can use jquery here too!
</script>
</head>
You should place your imported code into the script tag in your HTML page (application in your case), look at the following example:
<html>
<head>
<script type="text/javascript">
//Import your JS script here, e.g.:
function doSomething(){
..
}
</script>
</head>
<body>...</body>
</html>

Best way to access external JavaScript file and place contents in div?

So, lets say you have a page that wants to load from a javascript file and it includes
temp.html file
<script src="example.js"></script>
<p class="one"></p>
Now in the example.js file you have a function that is
function getInfo() {
var place = "foo"
$(".one").html(place);
}
//Edit currently I call the function inside the JS file
getInfo();
My question is how would you connect the two files so that the external javascript file knows that it is pointed to the paragraph with the class one?
Normally when this is in a single page, you would call the function and the info will be set.
I have seen a getScript method and a load method for Jquery. Would that be applicable here?
Any ideas on how to approach this? If you provide some code that will be super helpful.
Thanks in advance.
Looks like you want to execute getInfo() as soon as it's defined (i.e.: example.js is loaded).
You can try this approach:
<script src="example.js" onload="getInfo();"></script>
In your example.js, change getInfo() to something like this:
function getInfo() {
$(document).ready(function() {
var place = "foo"
$(".one").html(place);
});
}
Your language is confusing, but you could use jQuery's $(document).ready function which would suffice. Generally speaking, an externally loaded file should execute where the tag is in the script.
A hack could be to place a tag before the end of your document body, give it an id, and then use $('#id').ready() there. In general though, you could just try coding the transclusion concept (I'm guessing you're used to this) from scratch using intervals and timeouts.
<div id="rdy">
</div>
</body>
Then in your file:
$('#rdy').ready(getInfo);
Just my added opinion, you should consider that Google is up to some not-so-nice things these days, they are long-gone from the "do no evil" mantra.
If we assume you have a JavaScript file that contains this content:
function getInfo() {
var place = "foo"
$(".one").html(place);
}
then your markup will look something like this:
<html>
<head>
<meta charset="utf-8" />
<title></title>
<script src="//code.jquery.com/jquery-1.11.0.min.js"></script>
<script src="example.js"></script>
<script>
$(function(){
getInfo();
});
</script>
</head>
<body>
<p class="one"></p>
</body>
</html>
$(function(){ ... }); is just the simplified version of $(document).ready(function(){ ... });. They both more or less handle the onload event, which fires when page has finished loading.

Access object from script tag

I'm writing java script code in script tag in head like:
<head>
<script language="javascript">
object o = new object({....});
</script>
</head>
and trying to use object a in body tag
<body>
<script>
alert(o.value);
</script>
</body>
how can i access object from body???
is their any alternatives?
<head>
<script language="javascript">
var o = new Object();
o.value="a"
</script>
</head>
<body>
<script>
$(document).ready(function()
{
alert(o.value)
});
</script>
</body>
In this case var a is accessible in complete application, but one thing you need to make sure if you are using external JS files then it must be loaded when you using the variable. try onload function to assure JS is loaded and ready to use in body:
window.onload = function ()
{
alert(a);
}
Since your variable is declared outside any functions it can be accessed from anywhere in your document from the same script block or from a seperate script block like in your example. it can even be accessed from html event-attributes like this (note that its better to attach events to html elements using using js):
<button onclick="alert(a);">Click this button to open an alert!</button>

Include another HTML file in a HTML file

I have 2 HTML files, suppose a.html and b.html. In a.html I want to include b.html.
In JSF I can do it like that:
<ui:include src="b.xhtml" />
It means that inside a.xhtml file, I can include b.xhtml.
How can we do it in *.html file?
In my opinion the best solution uses jQuery:
a.html:
<html>
<head>
<script src="jquery.js"></script>
<script>
$(function(){
$("#includedContent").load("b.html");
});
</script>
</head>
<body>
<div id="includedContent"></div>
</body>
</html>
b.html:
<p>This is my include file</p>
This method is a simple and clean solution to my problem.
The jQuery .load() documentation is here.
Expanding lolo's answer, here is a little more automation if you have to include a lot of files. Use this JS code:
$(function () {
var includes = $('[data-include]')
$.each(includes, function () {
var file = 'views/' + $(this).data('include') + '.html'
$(this).load(file)
})
})
And then to include something in the html:
<div data-include="header"></div>
<div data-include="footer"></div>
Which would include the file views/header.html and views/footer.html.
My solution is similar to the one of lolo above. However, I insert the HTML code via JavaScript's document.write instead of using jQuery:
a.html:
<html>
<body>
<h1>Put your HTML content before insertion of b.js.</h1>
...
<script src="b.js"></script>
...
<p>And whatever content you want afterwards.</p>
</body>
</html>
b.js:
document.write('\
\
<h1>Add your HTML code here</h1>\
\
<p>Notice however, that you have to escape LF's with a '\', just like\
demonstrated in this code listing.\
</p>\
\
');
The reason for me against using jQuery is that jQuery.js is ~90kb in size, and I want to keep the amount of data to load as small as possible.
In order to get the properly escaped JavaScript file without much work, you can use the following sed command:
sed 's/\\/\\\\/g;s/^.*$/&\\/g;s/'\''/\\'\''/g' b.html > escapedB.html
Or just use the following handy bash script published as a Gist on Github, that automates all necessary work, converting b.html to b.js:
https://gist.github.com/Tafkadasoh/334881e18cbb7fc2a5c033bfa03f6ee6
Credits to Greg Minshall for the improved sed command that also escapes back slashes and single quotes, which my original sed command did not consider.
Alternatively for browsers that support template literals the following also works:
b.js:
document.write(`
<h1>Add your HTML code here</h1>
<p>Notice, you do not have to escape LF's with a '\',
like demonstrated in the above code listing.
</p>
`);
Checkout HTML5 imports via Html5rocks tutorial
and at polymer-project
For example:
<head>
<link rel="import" href="/path/to/imports/stuff.html">
</head>
Shameless plug of a library that I wrote the solve this.
https://github.com/LexmarkWeb/csi.js
<div data-include="/path/to/include.html"></div>
The above will take the contents of /path/to/include.html and replace the div with it.
No need for scripts. No need to do any fancy stuff server-side (tho that would probably be a better option)
<iframe src="/path/to/file.html" seamless></iframe>
Since old browsers don't support seamless, you should add some css to fix it:
iframe[seamless] {
border: none;
}
Keep in mind that for browsers that don't support seamless, if you click a link in the iframe it will make the frame go to that url, not the whole window. A way to get around that is to have all links have target="_parent", tho the browser support is "good enough".
A simple server side include directive to include another file found in the same folder looks like this:
<!--#include virtual="a.html" -->
Also you can try:
<!--#include file="a.html" -->
A very old solution I did met my needs back then, but here's how to do it standards-compliant code:
<!--[if IE]>
<object classid="clsid:25336920-03F9-11CF-8FD0-00AA00686F13" data="some.html">
<p>backup content</p>
</object>
<![endif]-->
<!--[if !IE]> <-->
<object type="text/html" data="some.html">
<p>backup content</p>
</object>
<!--> <![endif]-->
Following works if html content from some file needs to be included:
For instance, the following line will include the contents of piece_to_include.html at the location where the OBJECT definition occurs.
...text before...
<OBJECT data="file_to_include.html">
Warning: file_to_include.html could not be included.
</OBJECT>
...text after...
Reference: http://www.w3.org/TR/WD-html40-970708/struct/includes.html#h-7.7.4
Here is my inline solution:
(() => {
const includes = document.getElementsByTagName('include');
[].forEach.call(includes, i => {
let filePath = i.getAttribute('src');
fetch(filePath).then(file => {
file.text().then(content => {
i.insertAdjacentHTML('afterend', content);
i.remove();
});
});
});
})();
<p>FOO</p>
<include src="a.html">Loading...</include>
<p>BAR</p>
<include src="b.html">Loading...</include>
<p>TEE</p>
In w3.js include works like this:
<body>
<div w3-include-HTML="h1.html"></div>
<div w3-include-HTML="content.html"></div>
<script>w3.includeHTML();</script>
</body>
For proper description look into this: https://www.w3schools.com/howto/howto_html_include.asp
As an alternative, if you have access to the .htaccess file on your server, you can add a simple directive that will allow php to be interpreted on files ending in .html extension.
RemoveHandler .html
AddType application/x-httpd-php .php .html
Now you can use a simple php script to include other files such as:
<?php include('b.html'); ?>
This is what helped me. For adding a block of html code from b.html to a.html, this should go into the head tag of a.html:
<script src="https://code.jquery.com/jquery-1.10.2.js"></script>
Then in the body tag, a container is made with an unique id and a javascript block to load the b.html into the container, as follows:
<div id="b-placeholder">
</div>
<script>
$(function(){
$("#b-placeholder").load("b.html");
});
</script>
I know this is a very old post, so some methods were not available back then.
But here is my very simple take on it (based on Lolo's answer).
It relies on the HTML5 data-* attributes and therefore is very generic in that is uses jQuery's for-each function to get every .class matching "load-html" and uses its respective 'data-source' attribute to load the content:
<div class="container-fluid">
<div class="load-html" id="NavigationMenu" data-source="header.html"></div>
<div class="load-html" id="MainBody" data-source="body.html"></div>
<div class="load-html" id="Footer" data-source="footer.html"></div>
</div>
<script src="js/jquery.min.js"></script>
<script>
$(function () {
$(".load-html").each(function () {
$(this).load(this.dataset.source);
});
});
</script>
Most of the solutions works but they have issue with jquery:
The issue is following code $(document).ready(function () { alert($("#includedContent").text()); } alerts nothing instead of alerting included content.
I write the below code, in my solution you can access to included content in $(document).ready function:
(The key is loading included content synchronously).
index.htm:
<html>
<head>
<script src="jquery.js"></script>
<script>
(function ($) {
$.include = function (url) {
$.ajax({
url: url,
async: false,
success: function (result) {
document.write(result);
}
});
};
}(jQuery));
</script>
<script>
$(document).ready(function () {
alert($("#test").text());
});
</script>
</head>
<body>
<script>$.include("include.inc");</script>
</body>
</html>
include.inc:
<div id="test">
There is no issue between this solution and jquery.
</div>

You can use a polyfill of HTML Imports (https://www.html5rocks.com/en/tutorials/webcomponents/imports/), or that simplified solution
https://github.com/dsheiko/html-import
For example, on the page you import HTML block like that:
<link rel="html-import" href="./some-path/block.html" >
The block may have imports of its own:
<link rel="html-import" href="./some-other-path/other-block.html" >
The importer replaces the directive with the loaded HTML pretty much like SSI
These directives will be served automatically as soon as you load this small JavaScript:
<script async src="./src/html-import.js"></script>
It will process the imports when DOM is ready automatically. Besides, it exposes an API that you can use to run manually, to get logs and so on. Enjoy :)
Here's my approach using Fetch API and async function
<div class="js-component" data-name="header" data-ext="html"></div>
<div class="js-component" data-name="footer" data-ext="html"></div>
<script>
const components = document.querySelectorAll('.js-component')
const loadComponent = async c => {
const { name, ext } = c.dataset
const response = await fetch(`${name}.${ext}`)
const html = await response.text()
c.innerHTML = html
}
[...components].forEach(loadComponent)
</script>
To insert contents of the named file:
<!--#include virtual="filename.htm"-->
Another approach using Fetch API with Promise
<html>
<body>
<div class="root" data-content="partial.html">
<script>
const root = document.querySelector('.root')
const link = root.dataset.content;
fetch(link)
.then(function (response) {
return response.text();
})
.then(function (html) {
root.innerHTML = html;
});
</script>
</body>
</html>
Did you try a iFrame injection?
It injects the iFrame in the document and deletes itself (it is supposed to be then in the HTML DOM)
<iframe src="header.html" onload="this.before((this.contentDocument.body||this.contentDocument).children[0]);this.remove()"></iframe>
Regards
The Athari´s answer (the first!) was too much conclusive! Very Good!
But if you would like to pass the name of the page to be included as URL parameter, this post has a very nice solution to be used combined with:
http://www.jquerybyexample.net/2012/06/get-url-parameters-using-jquery.html
So it becomes something like this:
Your URL:
www.yoursite.com/a.html?p=b.html
The a.html code now becomes:
<html>
<head>
<script src="jquery.js"></script>
<script>
function GetURLParameter(sParam)
{
var sPageURL = window.location.search.substring(1);
var sURLVariables = sPageURL.split('&');
for (var i = 0; i < sURLVariables.length; i++)
{
var sParameterName = sURLVariables[i].split('=');
if (sParameterName[0] == sParam)
{
return sParameterName[1];
}
}
}​
$(function(){
var pinc = GetURLParameter('p');
$("#includedContent").load(pinc);
});
</script>
</head>
<body>
<div id="includedContent"></div>
</body>
</html>
It worked very well for me!
I hope have helped :)
html5rocks.com has a very good tutorial on this stuff, and this might be a little late, but I myself didn't know this existed. w3schools also has a way to do this using their new library called w3.js. The thing is, this requires the use of a web server and and HTTPRequest object. You can't actually load these locally and test them on your machine. What you can do though, is use polyfills provided on the html5rocks link at the top, or follow their tutorial. With a little JS magic, you can do something like this:
var link = document.createElement('link');
if('import' in link){
//Run import code
link.setAttribute('rel','import');
link.setAttribute('href',importPath);
document.getElementsByTagName('head')[0].appendChild(link);
//Create a phantom element to append the import document text to
link = document.querySelector('link[rel="import"]');
var docText = document.createElement('div');
docText.innerHTML = link.import;
element.appendChild(docText.cloneNode(true));
} else {
//Imports aren't supported, so call polyfill
importPolyfill(importPath);
}
This will make the link (Can change to be the wanted link element if already set), set the import (unless you already have it), and then append it. It will then from there take that and parse the file in HTML, and then append it to the desired element under a div. This can all be changed to fit your needs from the appending element to the link you are using. I hope this helped, it may irrelevant now if newer, faster ways have come out without using libraries and frameworks such as jQuery or W3.js.
UPDATE: This will throw an error saying that the local import has been blocked by CORS policy. Might need access to the deep web to be able to use this because of the properties of the deep web. (Meaning no practical use)
Use includeHTML (smallest js-lib: ~150 lines)
Loading HTML parts via HTML tag (pure js)
Supported load: async/sync, any deep recursive includes
Supported protocols: http://, https://, file:///
Supported browsers: IE 9+, FF, Chrome (and may be other)
USAGE:
1.Insert includeHTML into head section (or before body close tag) in HTML file:
<script src="js/includeHTML.js"></script>
2.Anywhere use includeHTML as HTML tag:
<div data-src="header.html"></div>
There is no direct HTML solution for the task for now. Even HTML Imports (which is permanently in draft) will not do the thing, because Import != Include and some JS magic will be required anyway.
I recently wrote a VanillaJS script that is just for inclusion HTML into HTML, without any complications.
Just place in your a.html
<link data-wi-src="b.html" />
<!-- ... and somewhere below is ref to the script ... -->
<script src="wm-html-include.js"> </script>
It is open-source and may give an idea (I hope)
You can do that with JavaScript's library jQuery like this:
HTML:
<div class="banner" title="banner.html"></div>
JS:
$(".banner").each(function(){
var inc=$(this);
$.get(inc.attr("title"), function(data){
inc.replaceWith(data);
});
});
Please note that banner.html should be located under the same domain your other pages are in otherwise your webpages will refuse the banner.html file due to Cross-Origin Resource Sharing policies.
Also, please note that if you load your content with JavaScript, Google will not be able to index it so it's not exactly a good method for SEO reasons.
Web Components
I create following web-component similar to JSF
<ui-include src="b.xhtml"><ui-include>
You can use it as regular html tag inside your pages (after including snippet js code)
customElements.define('ui-include', class extends HTMLElement {
async connectedCallback() {
let src = this.getAttribute('src');
this.innerHTML = await (await fetch(src)).text();;
}
})
ui-include { margin: 20px } /* example CSS */
<ui-include src="https://cors-anywhere.herokuapp.com/https://example.com/index.html"></ui-include>
<div>My page data... - in this snippet styles overlaps...</div>
<ui-include src="https://cors-anywhere.herokuapp.com/https://www.w3.org/index.html"></ui-include>
None of these solutions suit my needs. I was looking for something more PHP-like. This solution is quite easy and efficient, in my opinion.
include.js ->
void function(script) {
const { searchParams } = new URL(script.src);
fetch(searchParams.get('src')).then(r => r.text()).then(content => {
script.outerHTML = content;
});
}(document.currentScript);
index.html ->
<script src="/include.js?src=/header.html">
<main>
Hello World!
</main>
<script src="/include.js?src=/footer.html">
Simple tweaks can be made to create include_once, require, and require_once, which may all be useful depending on what you're doing. Here's a brief example of what that might look like.
include_once ->
var includedCache = includedCache || new Set();
void function(script) {
const { searchParams } = new URL(script.src);
const filePath = searchParams.get('src');
if (!includedCache.has(filePath)) {
fetch(filePath).then(r => r.text()).then(content => {
includedCache.add(filePath);
script.outerHTML = content;
});
}
}(document.currentScript);
Hope it helps!
Here is a great article, You can implement common library and just use below code to import any HTML files in one line.
<head>
<link rel="import" href="warnings.html">
</head>
You can also try Google Polymer
To get Solution working you need to include the file csi.min.js, which you can locate here.
As per the example shown on GitHub, to use this library you must include the file csi.js in your page header, then you need to add the data-include attribute with its value set to the file you want to include, on the container element.
Hide Copy Code
<html>
<head>
<script src="csi.js"></script>
</head>
<body>
<div data-include="Test.html"></div>
</body>
</html>
... hope it helps.
There are several types of answers here, but I never found the oldest tool in the use here:
"And all the other answers didn't work for me."
