struggling with this simple example of React for 3 hours :C . The "mainDiv" works fine as it should, but i see no HELLO WORLD there.
here is the code:
<html>
<head>
<title>REACT</title>
<link rel="stylesheet" href="style.css">
</head>
<body>
<div id="mainDiv" class="divstyle"></div>
<script type="text/babel">
let A = <div className="HW">HELLO WORLD!</div>;
let B = document.getElementById("mainDiv");
reactDOM.render(A,B);
</script>
<script src="https://unpkg.com/react#16.7.0/umd/react.production.min.js"></script>
<script src="https://unpkg.com/react-dom#16.7.0/umd/react-dom.production.min.js"></script>
<script src="https://unpkg.com/browse/babel-standalone#6.26.0/babel.min.js"></script>
</body>
======================= CSS =======================
.divstyle {
text-align: center;
background-color: #4285F4;
color: white;
height: 300px;
width: 100%;
font-size: 30px;
}
.HW {
text-align: center;
color: white;
}
Ok so here's some minor tweaks I made to get it working.
Put loading of Babel/React libs in the head tag
Use current, official Babel CDN, your one was giving me some issues in Chrome
Looks like you had a typo, you had reactDOM instead of ReactDOM
I tried this and it worked just fine:
<html>
<head>
<title>REACT</title>
<script src="https://unpkg.com/react#16.7.0/umd/react.production.min.js"></script>
<script src="https://unpkg.com/react-dom#16.7.0/umd/react-dom.production.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/babel-standalone/6.26.0/babel.min.js"></script>
</head>
<body>
<div id="mainDiv" class="divstyle"></div>
<script type="text/babel">
let A = <div className="HW">HELLO WORLD!</div>;
let B = document.getElementById("mainDiv");
ReactDOM.render(A,B);
</script>
</body>
in file public/index.html
<html>
<head>
<title>REACT</title>
<link rel="stylesheet" href="style.css">
</head>
<body>
<div id="root"></div>
<script src="https://unpkg.com/react#16.7.0/umd/react.production.min.js"></script>
<script src="https://unpkg.com/react-dom#16.7.0/umd/react-dom.production.min.js"></script>
<script src="https://unpkg.com/browse/babel-standalone#6.26.0/babel.min.js"></script>
</body>
in file index.js:
import React, { Component } from 'react';
import ReactDOM from 'react-dom';
class Index extends Component {
render() {
return (
<div className="HW">HELLO WORLD!</div>;
)
}
}
ReactDOM.render(<Index />, document.getElementById('root'));

Trying to render a hello world but nothing is displayed on the page. There are no messages displayed in the console. What am I missing here? Thank you.
<!DOCTYPE html>

var mount = document.querySelector('#app');
ReactDom.render(<App />, mount);
</script>

Your issue is that it is ReactDOM not ReactDom
class App extends React.Component {
render() {
return <h1>Hello from our app</h1>
}
}
var mount = document.querySelector('#app');
ReactDOM.render(<App />, mount);

I am trying to get a react JS app to render in IE 11 but it is not rendering. I believe I have tried all of the suggestions from https://github.com/facebook/react/issues/8379. This example renders fine in other browsers for me.
Here is my html file
<head>
<meta http-equiv="X-UA-Compatible" content="IE=EDGE" />
<script src="https://code.jquery.com/jquery-3.3.1.slim.min.js" integrity="sha384-q8i/X+965DzO0rT7abK41JStQIAqVgRVzpbzo5smXKp4YfRvH+8abtTE1Pi6jizo" crossorigin="anonymous"></script>

<script src="https://cdnjs.cloudflare.com/ajax/libs/react/0.13.3/JSXTransformer.js"> </script>
<script src="/static/js/test.jsx" type="text/jsx"></script>
</head>
<body>
<div id="root"></div>
<script type="text/jsx">
ReactDOM.render( < Test / > ,
document.getElementById('root')
);
</script>
</body>
</html>
and here is /static/js/test.jsx
class Test extends React.Component {
render() {
return ( < h1 > This is a test < /h1>);
}
One way to get it to work in IE11 is to import Babel to transpile ES6 to ES5 so it will work in IE11. Note that script type should be "text/babel" for both the inline script and the script import. Alternatively, you can transpile the javascript in the Babel repl and replace your code. Here's the html file
<!DOCTYPE html>
<html>
<head>
<title>First React App</title>
</head>
<body>
<div id="root"></div>
<script src="https://cdnjs.cloudflare.com/ajax/libs/babel-standalone/6.26.0/babel.min.js"></script>

<script

></script>
<script src="./Test.js" type="text/babel"></script>
<script type="text/babel">
"use strict";
ReactDOM.render(<Test />, document.getElementById("root"));
</script>
</body>
</html>
here's Test.js
"use strict";
class Test extends React.Component {
render() {
return <h1>Hello World</h1>;
}
}
I am trying to use some pre-builtin react component from a library called ant design. Also, I would like to call the react and the component library through a cdnjs(don't wish to use webpack or else). How could I accomplish it? My approaches are like below and it's not working for me.
<!DOCTYPE html>
<html>
<head>
<title></title>
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/antd/3.1.6/antd.min.css" />

<script src="https://cdnjs.cloudflare.com/ajax/libs/babel-standalone/6.21.1/babel.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/antd/3.1.6/antd.min.js"></script>
</head>
<body>
<div id="root"></div>
<script type="text/babel">
import Button from 'antd/lib/button';
class Greeting extends React.Component {
render() {
return (<p><Button type="primary">Primary</Button></p>);
}
}
ReactDOM.render(
<Greeting />,
document.getElementById('root')
)
</script>
</body>
</html>
You don't need to import, because when you use prebuilt version, it's already injected into a global variable call 'antd' (just like React)
I also updated a little bit your scripts because for React you need . the umd version and antd needs the with locale version.
However, using prebuilt version is strongly NOT RECOMMENDED be careful.

This is derived from my question here: Changing style on <body> element where the suggestion was to style a top level DIV. Having tried that I find that I get a different output using React compared to direct HTML. I am at a loss to understand why.
Consider a very simple react app consisting of a basic index.html file:
<!DOCTYPE HTML>
<html>
<head>
<style>
html { min-height: 100%; }
body { height: 100%; background-color: blue; margin: 0; }
</style>
</head>
<body>
<div id='root'></div>
<script src="https://fb . me / react-15.0.1.js"></script>
<script src="https://fb . me / react-dom-15.0.1.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/babel-core/5.8.23/browser.min.js"></script>
<script src="main.js" type="text/babel"></script>
</body>
</html>
and a corresponding main.js file
var TestDiv = React.createClass({
render: function () {
const style = {
divStyle: {
height: "100%",
background: "red"
}
}
return (
<div style={style.divStyle}>
<h1>Hello World</h1>
</div>
)
}
});
ReactDOM.render(<TestDiv/>, document.getElementById('root'));
Rendering this produces a blue screen with a red bar at the top with the text on. With the DIV set to a height of 100% I had expected the red background to fill the viewport.
Now, take the output from that React app (as given by Chrome Inspector) and create a simple html file from it.
<html>
<head>
<style>
html { min-height: 100%; }
body { height: 100%; background-color: blue; margin: 0; }
</style>
</head>
<body>
<div id="root">
<div data-reactroot="" style="height: 100%; background: red;">
<h1>Hello World</h1>
</div>
</div>
<script src="https://fb . me/react-15.0.1.js"></script>
<script src="https://fb . me/react-dom-15.0.1.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/babel-core/5.8.23/browser.min.js"></script>
<script src="main.js" type="text/babel"></script>
</body>
</html>
The code is essentially the same but this renders with the whole viewport in red and no blue at all.
Why?
I tried adding angular-carousel in my application and I am getting this error
Failed to instantiate module ngMaterial due to:

I got this error only after adding ngMaterial in my application with carousel. I am using latest stable version 1.5.8 of angularjs. This is my code I tried until now,

Am I wrong by someway?. Can someone please help me?
First Include All Dependencies
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.15/angular.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.15/angular-animate.js"></script>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.15/angular-aria.js"></script>
Than include Angular Material JS file
<script src="https://gitcdn.link/repo/angular/bower-material/master/angular-material.js"></script>
Looks like to don't include the ngMaterial js files
