阻止事件的默认行为、React阻止事件的默认行为

HTML中阻止事件的默认行为可以用return false

<a href="#" onclick="console.log('The link was clicked.'); return false">
 Click me
</a>

而React中只能显示调用e.preventDefault();

function ActionLink() {
 function handleClick(e) {
   e.preventDefault();
   console.log('The link was clicked.');
 }
 return (
   <a href="#" onClick={handleClick}>
     Click me
   </a>
 );
}
