I have the following code:
<head>
<title></title>
<link rel="stylesheet" href="./styles/darkula.css">
<link rel="stylesheet" href="./styles/github.css">
</head>
<body>
<div class="container">
<pre>
<code class="html">
<button class="button is-primary">Primary</button>
</code>
</pre>
<!-- Change theme button -->
<button onclick="changeTheme()">Change theme</button>
</div>
<script src="highlight.pack.js"></script>
<script>
hljs.initHighlightingOnLoad();
document.querySelectorAll("code").forEach(function(element) {
element.innerHTML = element.innerHTML.replace(/&/g, "&").replace(/</g, "<").replace(/>/g, ">").replace(/"/g, """).replace(/'/g, "'");
});
function changeTheme() {
...
}
</script>
</body>
I am loading 2 themes in my file. Because the github theme is being loaded after the darkula theme, it gets applied to all the code elements automatically. This is fine, but I would like to allow users to dynamically change the theme to darkula with the click of the button. I could not find anything in the documentation. How can I do this?
If you are using sass/scss and handle your dependencies with npm, you can do the next thing:
#use "sass:meta";
html[data-theme="light"] {
#include meta.load-css("highlight.js/styles/a11y-light");
}
html[data-theme="dark"] {
#include meta.load-css("highlight.js/styles/a11y-dark");
}
To make it to work, you need to define the data-theme attribute in your html tag.
<html data-theme="light">
<!-- ensure to change it with javascript and define one with default -->
...
</html>
There's a github response to this same question here https://github.com/highlightjs/highlight.js/issues/2115
Basically you include all the themes you want, and then disable all the link tags except for the selected theme.
The highlight.js demo page does this https://highlightjs.org/static/demo/
The GitHub repository is for the code can be found here.

I have an angular.js app where the index.html looks something like with ng-app in the <html> tag
<html lang="en" ng-app="app">
<head></head>
<body>
<custom-navbar-directive></custom-navbar-directive> //angular js directive
<custom-loader></custom-loader>
<!-- To render components -->
<div ui-view ng-cloak></div>
</body>
</html>
I was following the steps in the single-spa angular.js guide. I removed the ng-app from <html> tag and added the following in my app.js
System.register([], function (_export) {
return {
execute: function () {
_export(
window.singleSpaAngularjs.default({
angular: angular,
mainAngularModule: "app",
uiRouter: true,
preserveGlobal: false,
})
);
},
};
});
Also I did the import map and singleSpa.registerApplication steps in the index.html
My issue is now the content is rendering but the <custom-navbar-directive> and <custom-loader> are missing. I added them inside the index.html since they are commonly used in each html template.
When I inspect and checked the rendered html I noticed that they are outside the loaded single spa angularjs app
<custom-navbar-directive></custom-navbar-directive>
<custom-loader></custom-loader>
<div id="single-spa-application:legacyAngularApp">
<div id="__single_spa_angular_1" class="ng-scope">
<!-- content -->
</div>
</div>
I guess since they are directives if those are inside the <div id="__single_spa_angular_1" class="ng-scope"> then it should render.
Any idea how to solve this?
I've tried every combination that was given in the answers throughout the different sites.
Here's my code.
<div class="circular" v-bind:style="{ 'background-image': 'url(' + require('../assets/kafa.jpg') + ')' }"></div>
The problem is (I think) that path is good, and image is found, it just won't show on the background (or anywhere for that matter).
And here is the image of the page and Inspect Elements
Thanks.
Okay, so I found the problem. I closed the tag in the same line, instead of wrapping whole template in that div.
According to vue documentation:
https://v2.vuejs.org/v2/guide/class-and-style.html
in the section of “Binding Inline Styles” and “Object Syntax” it describes that you could define peroperty-values of styles in the “data” part of “vue instance”. This is what I was doing for implementing that:
new Vue ({
el: "#app",
data: {
activeColor: "red",
backImg: 'url("galaxy.jpg")'
}
});
.circular {
min-height: 1080px;
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<link rel="stylesheet" href="style.css">
</head>
<body>
<div id="app">
<div class="circular" v-bind:style="{color: activeColor, backgroundImage: backImg}"> texts to show styles</div>
</div>
<script src="vue.js"></script>
<script src="myScript.js"></script>
</body>
</html>
I used the “camelCase” format and the image is something different, you can substitute your own “url” in the “data” part of “vue instance” in the script code. I could not upload my used image, but you could test your own image.
I am trying to inject some React code into an HTML document. I am following React's own documentation and feeding their starter code (a simple like button) into the page. Everything was working great. I changed it to use JSX, changed it to a functional component using hooks instead of a class component with state. No problems.
However, whenever I include an import call and try to bring in another component, the component breaks on the page and stops displaying, but doesn't throw any kind of error I can see.
How do I develop in a "react-y" way with components and modularity while injecting it into an html page?
Here is the code I'm working with at the moment:
HTML document
<body>
<div id="react-root"></div>
<!-- inject react, reactDOM and JSX engine -->
<script src="https://unpkg.com/react#16/umd/react.development.js" crossorigin></script>
<script src="https://unpkg.com/react-dom#16/umd/react-dom.development.js" crossorigin></script>
<script src="https://unpkg.com/babel-standalone#6/babel.min.js"></script>
<!-- point to component -->
<script src="transpiled/app.js"></script>
</body>
React Component
'use strict';
import {SecondComponent} from './components/SecondComponent';
const e = React.createElement;
const LikeButton = () => {
const [liked, setLiked] = React.useState(false);
if (liked) return 'You liked this functional component.'
const handleLikeClick = () => {
setLiked(true);
}
return (
<div>
<button onClick={handleLikeClick}>new like button with jsx</button>
{liked && <SecondComponent/>}
</div>
)
}
const domContainer = document.querySelector('#react-root');
ReactDOM.render(e(LikeButton), domContainer);
Like I said, any sort of import statement seems to be where it breaks. Can't find resources online about it. Thanks in advance for your help!
UPDATE: After a bit of research importing modules between several <script> tags is now possible.
This can be achieved adding the Babel Plugin attribute data-plugins and setting the value to "transform-es2015-modules-umd" which will enable the UMD pattern.
You'll also need to set type="text/babel" on each <script> tag.
This will allow you to use the import statements directly inside each file. Like this:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>React</title>
<script src="https://unpkg.com/react#16/umd/react.development.js"></script>
<script src="https://unpkg.com/react-dom#16/umd/react-dom.development.js"></script>
<script src="https://unpkg.com/babel-standalone#6/babel.min.js"></script>
</head>
<body>
<div id="root"></div>
<script data-plugins="transform-es2015-modules-umd" type="text/babel" src="./Header.js"></script>
<script data-plugins="transform-es2015-modules-umd" type="text/babel" src="./App.js"></script>
</body>
</html>
Working Gist Example
I'm stuck on something very simple and can't seem to figure out what I'm doing wrong. I've created a blank project in ionic and would like to set a default home screen as the first view loaded. I'm staring at a blank screen when I run this in the browser.
My code is as follows:
app.js
// Ionic Starter App
// angular.module is a global place for creating, registering and retrieving Angular modules
// 'starter' is the name of this angular module example (also set in a <body> attribute in index.html)
// the 2nd parameter is an array of 'requires'
var app = angular.module('starter', ['ionic'])
app.run(function($ionicPlatform) {
$ionicPlatform.ready(function() {
if(window.cordova && window.cordova.plugins.Keyboard) {
// Hide the accessory bar by default (remove this to show the accessory bar above the keyboard
// for form inputs)
cordova.plugins.Keyboard.hideKeyboardAccessoryBar(true);
// Don't remove this line unless you know what you are doing. It stops the viewport
// from snapping when text inputs are focused. Ionic handles this internally for
// a much nicer keyboard experience.
cordova.plugins.Keyboard.disableScroll(true);
}
if(window.StatusBar) {
StatusBar.styleDefault();
}
});
})
app.config(function ($stateProvider, $urlRouterProvider) {
$urlRouterProvider.otherwise('/')
$stateProvider.state('home_screen', {
url:'/',
templateUrl: 'home_screen.html'
})
})
home_screen.html
<ion-pane>
<ion-header-bar class="bar-stable">
<h1 class="title">Home Screen</h1>
</ion-header-bar>
<ion-content>
<div class="spacer" style="height: 100px;"></div>
<div class="col col-33 col-offset-33">
<button class="button button-block button-balanced">Play</button>
</div>
<div class="spacer" style="height: 100px;"></div>
<div class="col col-33 col-offset-33">
<a class="button button-outline button-block button-balanced" href="#/app/about">About</a>
</div>
</ion-content>
</ion-pane>
index.html
<!DOCTYPE html>

</head>
<body ng-app="starter">
<ion-nav-view></ion-nav-view>
</body>
</html>
home_screen.html will work just fine when I include it in the index.html but does not work when I try to set it as the default view. I tried following the tutorial from here:
http://learn.ionicframework.com/formulas/navigation-and-routing-part-1/
Any help would be appreciated.
Actually you have to uncomment the ion-nav-view in your index.html file. You don't have to give that a name even. Try to add this in your index.html file:
...
<body ng-app="starter">
<ion-nav-view></ion-nav-view>
</body>
...
To get started with ionic I also recommend to look at other starter projects like tabs or sidemenu which are described here.
Here is the code that should render a "raised" paper-button:
All the code is in a script tag and renders a paper-button that is not RAISED (see screen shot). I can click and see the RIPPLE effect, seems perfect except the appearance.
UPDATE :
for the moment the only way to get the correct rendering is by replacing
<paper-button raised>test</paper-button>
BY
<div dangerouslySetInnerHTML={{__html: '<paper-button raised>test</paper-button>'}} />
ANY WORKAROUND avoiding this 'dangerous' way?
<!DOCTYPE html>
<html>
<head>
<script src="bower_components/webcomponentsjs/webcomponents.min.js"></script>
<link rel="import" href="bower_components/polymer/polymer.html">
<link rel="import" href="bower_components/paper-button/paper-button.html">
<title>Hello React</title>
<script src="bower_components/react/react.min.js"></script>
<script src="bower_components/react/JSXTransformer.js"></script>
</head>
<body>
<div id="content">
</div>
<script type="text/jsx">
var ButtonT = React.createClass({
render: function() {
return (
<div>
<paper-button raised="true">test</paper-button>
</div>
);
}
});
React.render(
<ButtonT />,
document.getElementById('content')
);
</script>
</body>
</html>
Should the "raised" attribute be passed as a this.props...?
It won't work in the current version of React. Custom attribute support is an open issue, though. For now, I've found this patch works well.
In JSX if you want a custom HTML attribute, you should prefix it with data-, it then will be resolved to actual name without prefix. See docs;
