I'm connected to my server via npm install -g http-server on Terminal, that's working fine. I just want to see if my h1 tag works so I can proceed to making a practice website. I feel like my mainPage.html may be a little off.
Here's my mainPage.html file:
<!DOCTYPE html>
<html>
<head>
<title>Testing</title>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.1/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>
</head>
<body>
</body>
<div id="website"></div>
<script type="text/babel" src="mainPage.js"></script>
</script>
</html>
Here's my mainPage.js file:
var Website = React.createClass({
render: function() {
return(
<h1>Why won't my h1 tag appear!</h1>
);
}
});
ReactDOM.render(<Website/>, document.getElementById('website'));
You need to import babel.js, react and reactDOM
<script src="https://cdnjs.cloudflare.com/ajax/libs/babel-standalone/6.23.1/babel.min.js"></script>
<script src="https://unpkg.com/react#15/dist/react.min.js"></script>
<script src="https://unpkg.com/react-dom#15/dist/react-dom.min.js"></script>
Include the reference of react, react-dom and babel, Check this working code:
<!DOCTYPE html>
<html>
<head>
<title>Testing</title>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.1.0/react-dom.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/babel-standalone/6.23.1/babel.min.js"></script>
</head>
<body>
</body>
<div id="website"></div>
<script type="text/babel" >
var Website = React.createClass({
render: function() {
return(
<h1>Why won't my h1 tag appear!</h1>
);
}
});
ReactDOM.render(<Website/>, document.getElementById('website'));
</script>

I have tried everything I could, searched a lot of answers, but none of them helped, I just can't understand why my code is not working, I have cross checked me code with instructor's code, still i am having a blank screen before me, kindly help.
You need bable.js CDN in head tag too.
ReactDOM not ReactDom

I recommended you to follow the create-react-app approach which is very simple and easy way to start with reactjs.

I am following the Redux tutorial and trying to include Provider. I am using JSbin

</html>
JS File:
const { Provider } = ReactRedux;
However I am getting the error:
"ReferenceError: ReactRedux is not defined
What am I doing wrong?
In your snippet you posted, you have scr and not src.
<script scr="https://cdnjs.cloudflare.com/ajax/libs/react-redux/5.0.5/react-redux.js"></script>
Should be
<script src="https://cdnjs.cloudflare.com/ajax/libs/react-redux/5.0.5/react-redux.js"></script>
Kotlin versions 1.0.x-1.1.0 support out of the box unit testing with QUnit but when I load tests it throws this exception:
ReferenceError: ok is not defined

This is my test class:
import org.junit.Test
import kotlin.test.assertEquals
class AppTest {
#Test fun myFirstTest() {
assertEquals(1, 1, "Test in test folder works")
}
}
This is the html code that loads the test:
<!doctype html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>Fibonacci Counter</title>
<link rel="stylesheet" href="css/app.css">
<meta name="viewport" content="width=device-width">
<link rel="stylesheet" href="https://code.jquery.com/qunit/qunit-2.1.1.css">

<script src="lib/kotlin-test-js.js"></script>
<script src="app_main.js"></script>
<script src="app_test.js"></script>

</html>
The problem is in the version of QUnit 2.1.1, by using version 1.23.1 the problem is solved.
This is the html code that loads the test with the fix:
<!doctype html>

I am new to qunit.I am running simple testcase in qunit.but nothing is getting displayed on screen.
This is HTML Runner:-
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>QUnit Demo</title>
<link rel="stylesheet" href="//code.jquery.com/qunit/qunit-1.14.0.css">
<script src="//code.jquery.com/qunit/qunit-1.14.0.js"></script>
<script src="MyJsUnitTests.js"></script>
<script src="MyJsSourceCode.js"></script>
</head>
<body>
<div id="qunit"></div>
<div id="qunit-fixture"></div>
</body>
</html>
This is MyJsSourceCode.js
var ArthimeticOperations = {
addTwoNumbers : function (number1, number2) {
return number1 + number2;
}
}
This is MyJsUnitTests.js
test('Addition Test', function () {
strictEqual(ArthimeticOperations.addTwoNumbers(3, 5), 8, "Tested the addition functionality");
});
Try swapping the source code and test code includes... my guess is that your tests start running before the source code is included in the page:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>QUnit Demo</title>
<link rel="stylesheet" href="//code.jquery.com/qunit/qunit-1.14.0.css">
<script src="//code.jquery.com/qunit/qunit-1.14.0.js"></script>
<!-- SWAP THESE TWO...
<script src="MyJsUnitTests.js"></script>
<script src="MyJsSourceCode.js"></script>
Like so:
-->
<script src="MyJsSourceCode.js"></script>
<script src="MyJsUnitTests.js"></script>
</head>
<body>
<div id="qunit"></div>
<div id="qunit-fixture"></div>
</body>
</html>
