If a React Class name starts with a lowercase letter then no methods inside the class get called, i.e. nothing Renders, and you don't get any error message in the Browser console,
because small letters are treated as HTML elements, its a rule that all React components must start with a upper case letter, so always use Upper Case.
Instead of reactTest use this: ReactTest it will work.
As per DOC:
User-Defined Components Must Be Capitalized.
When an element type starts with a lowercase letter, it refers to a built-in component like
<div>or<span>and results in a string 'div' or 'span' passed toReact.createElement. Types that start with a capital letter like<Foo />compile toReact.createElement(Foo)and correspond to a component defined or imported in your JavaScript file.We recommend naming components with a capital letter. If you do have a component that starts with a lowercase letter, assign it to a capitalized variable before using it in JSX.
Check the working code:
<!DOCTYPE html>
<html>
<head>
<title>React without npm</title>
<script src="https://unpkg.com/react@15/dist/react.js"></script>
<script src="https://unpkg.com/react-dom@15/dist/react-dom.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/babel-core/5.8.24/browser.js"></script>
</head>
<body>
<div id="test"></div>
<script type="text/babel">
var ReactTest = React.createClass({
render: function(){
return(
<h1>React Without NPM</h1>
);
}
});
ReactDOM.render(<ReactTest />,document.getElementById('test'));
</script>
</body>
</html>The following works fine, try it :
var ReactTest = React.createClass({
render: function(){
return(
<h1>React Without NPM</h1>
);
}
});
ReactDOM.render(<ReactTest />,document.getElementById('test'));<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>
<div id="test" ></div>If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
