I'm building a small application in Play and have an 'outer' template which holds all my CSS and JS imports (jQuery and my main.js file). CSS at the top, JS at the bottom with a body tag in between... pretty basic stuff:
<html>
<head>
<title>test</title>
<link rel="stylesheet" href="#routes.Assets.at("stylesheets/foundation.css")">
<link rel="stylesheet" href="#routes.Assets.at("stylesheets/main.css")">
<link rel="shortcut icon" type="image/png" href="#routes.Assets.at("images/favicon.png")">
</head>
<body>
#content
</body>
<script src='#routes.Assets.at("javascripts/jquery-1.9.0.min.js")' type="text/javascript"></script>
<script src='#routes.Assets.at("javascripts/index.js")' type="text/javascript"> </script>
</html>
Which is fine.
However, I have page specific javascript functions that should run based on what the page is. So if I go to localhost:9000/test, I want a particular set of functions to run.
If I go to localhost:9000/chips, I want another set of functions to run.
I can't see a neat way of doing this, really, except checking the current page url in the script and executing functions based on that... but the routes file is already doing stuff based on the current page url - seems strange to have to do something so similar twice.
One solution is to put all my scripts at the top and then execute inline scripts in the HTML... but I hate doing things like that.
You have very nice and clear sample available in the... documentation.
Scroll to the bottom and check section: moreScripts and moreStyles equivalents, you have there ready to use samples.
I use a ViewModel approach to solve this issue.
The default ViewModel:
class DefaultPage(
implicit val request: RequestHeader,
implicit val lang: Lang) {
var title: String = null
val styles = mutable.LinkedHashMap.empty[String, Int]
val scripts = mutable.LinkedHashMap.empty[String, Int]
def title(title: String) {
this.title = title
}
def style(style: String)(implicit priority: Int = 500) {
styles.put(style, priority)
}
def script(script: String)(implicit priority: Int = 500) {
scripts.put(script.toString, priority)
}
def translate(message: String, objects: Any*) = Messages(message, objects: _*)
}
Then I have two template tags:
styles.scala.html
#(styles: scala.collection.mutable.Map[String, Int])
#for(style <- styles.toList.sortBy(_._2)) {
<link rel="stylesheet" href="#routes.Assets.at(style._1)" />
}
scripts.scala.html
#(scripts: scala.collection.mutable.Map[String, Int])
#for(script <- scripts.toList.sortBy(_._2)) {
<script async="true" src="#routes.Assets.at(script._1)"></script>
}
My main template:
main.scala.html
#(page: util.view.models.DefaultPage)(content: Html)
#import tags.scripts
#import tags.styles
#page.style("css/vendor/normalize.min.css")(1)
#page.style("css/vendor/formalize.min.css")(1)
#page.style("css/sprites.min.css")(1)
#page.style("css/main.min.css")(1)
#page.style("css/quirks.min.css")(1000)
#page.script("js/vendor/jquery-1.9.1.min.js")(1)
#page.script("js/vendor/jquery.formalize.min.js")(1)
#page.script("js/plugins.min.js")(1)
#page.script("js/main.min.js")(1)
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title>#page.title</title>
<meta name="description" content="" />
<meta name="viewport" content="width=device-width" />
#styles(page.styles)
<script src="#routes.Assets.at("js/vendor/modernizr-2.6.2.min.js")"></script>
</head>
<body class="#page.lang.code #page.lang.language #page.lang.country">
#content
#scripts(page.scripts)
</body>
And a sub template:
#(page: util.view.models.ContactUsPage)
#page.title(page.translate("contact.us.title"))
#page.style("css/contact-us.min.css")
#page.script("js/vendor/jquery.expandable-1.1.4.js")
#page.script("js/contact-us.min.js")
#main(page) {
}
You can pass your javascript which is specific to a page as template parameter link

I need my webite to display info in a certain language, based on a query in my webite's URL (e.g. www.website.com/index.php?country=FR). How can I do that with vanilla JS and not React/Angular?
My approach:
1) JS recognizes a query in the URL (in this case- 'country=FR') and then appends a js file, which has neccessary french words in it defined by variables.
2) JS in my script tag that's in the HTML file, appends the main page markup text with template literals in it.
3)
I don't know, whether the browser fails to either fetch the language file itself or its variables. At the moment it does not render anything.

markupAppend()

var domain = window.location.href;
var FRString = domain.includes("country=FR");
var ESString = domain.includes("country=ES");
if (FRString) {
$('head').append(`<script src="./Language_files/FRENCHwords.js" />`)
}
if (ESString) {
$('head').append(`<script src="./Language_files/SPANISHwords.js" />`)
}
=========================

const goodmorning = 'Bonjour';
const goodevening = 'Bonsoir';
const mynameis = 'Mon nom est';
=========================
SPANISHwords.js
const goodmorning = 'Buenos dias';
const goodevening = 'Buenas tardes';
const mynameis = 'Mi nombre es';
No errors displayed, the page is just not rendering...
In Your main.js file, you are using domain.includes, it only returns the domain name but not the entire URL. You can use window.location.href.includes for this.
Instead of: domain.includes("country=FR");
Try: window.location.href.includes("country=FR");
I am using modern Javascript MyClass.js
export default class MyClass {
constructor(x) {
this.val=x? x: "Hello!"
console.log("MyClass:",x)
}
}
at my http://localhost/myfolder/mypage.htm, with the source below,
<!DOCTYPE html>
<html>
<head>
<title>test</title>
<meta charset="utf-8" />
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<link rel='shortcut icon' type='image/x-icon' href='./favicon.ico' />
<script type="module" src="./MyClass.js"></script>
<script>
'use strict';
document.addEventListener('DOMContentLoaded', function(){
alert(123)
let x = new MyClass(11);
}, false); //ONLOAD
</script>
</head>
<body> <p>Hello1!</p> </body>
</html>
Why console say "Uncaught ReferenceError: MyClass is not defined"?
PS: this question is a complement for this other about using ES6+ with browser+NodeJs.
NOTE: using UBUNTU ith Apache's Localhost... Some problem with myfolder a symbolic link to real folder? at /var/www/html I used ln -s /home/user/myRealFolder/site myfolder
you need to import the module before using it
<!DOCTYPE html>
<html>
<head>
<title>test</title>
<meta charset="utf-8" />
<script type="module" src="./MyClass.js"></script>
<script type="module" id="m1">
// script module is an "island", not need onload.
'use strict';
import MyClass from './MyClass.js';
let x = new MyClass(11); // we can use here...
console.log("debug m1:", x) // working fine!
window.MyClassRef = MyClass; // "globalizing" class
window.xRef = x // "globalizing" instance
</script>
<script> // NON-module global script
document.addEventListener('DOMContentLoaded',function(){
// only works after all modules loaded:
console.log("debug:", window.xRef) // working fine!
let x = new window.MyClassRef(22); // using class also here,
console.log("debug:", x) // working fine!
}, false); //ONLOAD
</script>
</head>
<body> <p>Hello1!</p> </body>
</html>
There are two ways to use an imported class:
at module scope (script m1): you can use new MyClass(), and can "globalize" instances (e.g. xRef) or the costructor's class (MyClassRef).
at global scope: to work together other libraries or with main script, use a global reference, e.g. new window.MyClassRef().
All this solution relies upon "static import"...
Optional dynamic import
You can use also import with ordinary default <script> (no type="module"), and no "onload", using this solution, instead the last script:
<script>
'use strict';
import('./MyClass.js').then(({default: MyClass}) => {
alert(123) // async block
let x = new MyClass(11);
});
</script>
See dynamic import.
Sorry for the bad english :P
I'm using ASP.NET
I'm trying to use a JavaScript that I've found on the Internet to set masks to my telephone and cellphone text fields, but the JS code just work at the fields that are located at my MasterPage. I don't have much experience with JS (almost none) and I have no idea how to resolve this since there is no error at my Logcat.
I tried to reference it at my MasterPage's head, body and inside the ContentPlaceHolder.
Here is the JS code:
function mascara(o, f) {
v_obj = o
v_fun = f
setTimeout("execmascara()", 1)
}
function execmascara() {
v_obj.value = v_fun(v_obj.value)
}
function mtel(v) {
v = v.replace(/\D/g, "");
v = v.replace(/^(\d{2})(\d)/g, "($1)$2");
v = v.replace(/(\d)(\d{4})$/, "$1-$2");
return v;
}
function id(el) {
return document.getElementById(el);
}
window.onload = function () {
id('txtTelefone').onkeypress = function () { //Located at MasterPage - working
mascara(this, mtel);
}
id('txtCelular').onkeypress = function () { //Located at MasterPage - working
mascara(this, mtel);
}
id('telefoneContato').onkeypress = function () { //Located at Contact Page - not working
mascara(this, mtel);
}
id('txtCelularUser').onkeypress = function () { //Located at User Page - not working
mascara(this, mtel);
}
id('txtTelefoneUser').onkeypress = function () { //Located at User Page - not working
mascara(this, mtel);
}
}
As I said before I tried to reference my JS file in some places, the codes that I tried were:
<script src="<%# Page.ResolveClientUrl("../Componentes/js/mascaras.js") %>"></script>
<script src="../Componentes/js/mascaras.js"></script>
As you can see, the fields are located in diferent pages, I also tried to put the code directly at the pages but I had no luck.
I think that I don't need to post my entire MasterPage here, then I'll put just the head, but if exists a need I will edit the post.
<head runat="server">
<title></title>

EDIT 1
Tried this:
id('<%= txtTelefoneContato.ClientID %>').onkeypress = function () { //Located at Contact Page - Still not working
mascara(this, mtel);
}
id('<%= txtCelularUser.ClientID %>').onkeypress = function () { //Located at User Page - Still not working
mascara(this, mtel);
}
id('<%= txtTelefoneUser.ClientID %>').onkeypress = function () { //Located at User Page- Still not working
mascara(this, mtel);
}
The reference to the script is at MasterPage head. But the problem still the same
EDIT2
Im receiving this when I inspect my page:
Error image 1
Error image 2
Resolved
As VDWWD explained, I just put the JS code directly at the .aspx pages with this modification:
from:,
id('txtCelularUser').onkeypress = function () {
mascara(this, mtel);
}
to:
id('<%= txtCelularUser.ClientID %>').onkeypress = function () {
mascara(this, mtel);
}
Thank you in advance
You have to use it like this when accessing elements with JavaScript that have master pages. And it's also better to use it even without master pages. If you should change the ID in you don't have to change it also in your script.
id('<%= txtTelefoneUser.ClientID %>').onkeypress
If you look at the HTML source you will see that the ID of the element has been changed from txtTelefoneUser to something like this ContentPlaceHolder_txtTelefoneUser. Aspnet adds a prefix to ensure every element has a unique ID.
You will see the same usage of prefix in elements that repeat data like GridView/Repeater/DataList etc.
UPDATE
If you put the javascript in an external file you can put a reference to it on the master page like this (assuming Componentes is a folder in the root):
<script src="/Componentes/js/mascaras.js" type="text/javascript"></script>
However putting <%= txtTelefoneUser.ClientID %> in an external file will not work, only on an .aspx page. To make that work declare those elements as variables an assign them on the aspx page while using them in the external js file.
Below a demo:
In the external javascript file:
var myElement;
function myFunction() {
myElement.value = "Success!";
}
and then on the .aspx page:
<script type="text/javascript">
myElement = document.getElementById("<%= TextBox1.ClientID %>");
</script>
After a long time I found that the elements that area inside the Content to be found in javascript must have the name of the content ID in front more undeline and the name of the element ID, you are looking for.
example:
document.querySelector("#ContentPlaceHolder1_img1").setAttribute("src", 123);
I am creating an O365 app and I have 2 .aspx files, when the user clicks on the O365 mail app, I want each of these pages to be loaded based on the subject of the mail.
Scenario 1: Mail subject contains '#'
result: load page1
Scenario 2: Mail subject does not contain '#'
result: load page2
I have tried having an intermediate .js file where I have written the logic,
but when I do window.location = "path_to_aspx_file",
only the html is loaded but the js files do not run.
My current implementation:
I have LandingLogic.js
(function () {
"use strict";
//The Office initialize function must be run each time a new page is loaded
Office.initialize = function (reason) {
$(document).ready(function () {
var item = Office.cast.item.toItemRead(Office.context.mailbox.item);
var sub = item.subject;
if (sub.indexOf("some text") > -1) {
window.location = "http://localhost:51776/File1.aspx";
}
else {
window.location = "http://localhost:51776/File2.aspx";
}
});
};
})();
After a bit of fumbling around.
I am able to navigate to each of these files now, but I am not sure how to access the mail subject from File1.aspx and File2.aspx.
Did you initialize the Office context before you using Office JavaScript API to get the subject? To redirect the HTML page easily, we can include the JavaScript like below:
Home.js:
/// <reference path="../App.js" />
(function () {
"use strict";
// The Office initialize function must be run each time a new page is loaded
Office.initialize = function (reason) {
$(document).ready(function () {
app.initialize();
RedirectHTMLPage();
});
};
function RedirectHTMLPage() {
var subject = Office.context.mailbox.item.subject;
if (subject.indexOf("#") != -1) {
window.location.href = "https://localhost:44300/page1.aspx";
} else {
window.location.href = "https://localhost:44300/page2.aspx";
}
}
})();
The HTML page for redirecting:

Would you mind sharing the detail you using the “window.load”?
Fei Xue answer is correct . if you want to get subject from file2.aspx , add office.js reference and access subject same as file1.aspx inside the Office.initialize event
<script src="https://appsforoffice.microsoft.com/lib/1/hosted/office.js" type="text/javascript"></script>
I have two scripts and I need to use script1 function in script2. Whats the best way to do it and Is there any simplification using prototype to access function in more scripts. I am using jquery.
script1
$(function(){
function process(){
// some code
}
})
script2
$(function(){
// I would like to use the process function here
}

Hope this help you.
You can use javascript functions as variables. So just reread your question about the same stuff about variables - Unable to access variable
So just do so your function will be available from global scope.
Just move the function declaration outside the ready event handler, that will make it globally available.
Another idea: use objects:
var Ob = {
process: function(callback) {
callback();
}
}
script1
$(function(){
Ob.process(function(){
... // code
});
});
script 2 (do same)
$(function(){
Ob.process(function(){
... //another code
});
});
If you are using same process function (means same body content, make same thing in both script) then
var Ob = {
process: function() {
...//put code
}
}
script1
$(function(){
Ob.process();
});
script 2 (do same)
$(function(){
Ob.process();
});
