react.js怎么使用for in

Answer 1

　react.js这样使用FOR 语句的：
　　// These two are equivalent in JSX for disabling a button
<input type="button" disabled />;
<input type="button" disabled={true} />;
// And these two are equivalent in JSX for not disabling a button
<input type="button" />;
<input type="button" disabled={false} />;
