"```javascript element.addEventListener('click', function(event) { event.preventDefault(); });


```javascript
element.onclick = function(event) {
  event.preventDefault();
};

element.attachEvent('onclick', function(event) {
  event.returnValue = false;
});

document.querySelector('form').addEventListener('submit', function(event) {
  event.preventDefault();
});
```"
