[React] React Fundamentals: Introduction to Properties

复制代码
    var React_app = React.createClass({
        render: function() {
            var age = this.props.age;
            var name = this.props.name;
            var isMan = this.props.isMan ? 'Man' : 'Woman';
            return (
                 <div>
                    <b>Should have (), if you have mutli tag in return, include them into a div</b>
                    <h1>Hello React World!</h1>
                         <h2>Show num: {age}, name: {name}, sex:{isMan}</h2>
                 </div>
            );
        }
    });
复制代码

 

You can set default properties:

复制代码
    var React_app = React.createClass({
        getDefaultProps: function() {
            return {
                age: 0,
                name: "Who?",
                isMan: true
            }
        },
        render: function() {
            var age = this.props.age;
            var name = this.props.name;
            var isMan = this.props.isMan ? 'Man' : 'Woman';
            return (
                 <div>
                    <b>Should have (), if you have mutli tag in return, include them into a div</b>
                    <h1>Hello React World!</h1>
                         <h2>Show num: {age}, name: {name}, sex:{isMan}</h2>
                 </div>
            );
        }
    });
复制代码

 

You can set the type of props:

复制代码
<!DOCTYPE html>
<html>
<head lang="en">
    <meta charset="UTF-8">
    <title>React Lesson 2: Prop</title>
</head>
<body>

<script src="https://cdnjs.cloudflare.com/ajax/libs/react/0.12.2/react.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/react/0.12.2/JSXTransformer.js"></script>
<script type="text/jsx">

    var React_app = React.createClass({
        getDefaultProps: function() {
            return {
                age: 0,
                name: "Who?",
                isMan: true
            }
        },
        propTypes: {
            name: React.PropTypes.string.isRequired,
            age: React.prototype.number,
            isMan: React.prototype.bool
        },
        render: function() {
            var age = this.props.age;
            var name = this.props.name;
            var isMan = this.props.isMan ? 'Man' : 'Woman';
            return (
                 <div>
                    <b>Should have (), if you have mutli tag in return, include them into a div</b>
                    <h1>Hello React World!</h1>
                         <h2>Show num: {age}, name: {name}, sex:{isMan}</h2>
                 </div>
            );
        }
    });

    React.render(<React_app name="John"/>, document.body);
</script>
</body>
</html>
