How to override *only* left click on anchor?
I know I can use event.preventDefault() to stop a link from being followed. But I only want to prevent the default action on a plain left-click or touch-tap. shift-left-click, ctrl-left-click, right click, and middle click should all perform the default action.
How can I detect a plain left-click or touch tap?
Solution 1:
You can check MouseEvent properties like button, altKey, shiftKey & ctrlKey to do this
document.getElementById('test').addEventListener('click', function(event) {
snippet.log('button: ' + event.button);
snippet.log('ctrlKey: ' + event.ctrlKey);
snippet.log('shiftKey : ' + event.shiftKey);
snippet.log('altKey : ' + event.altKey);
if (event.button == 0 && !event.ctrlKey && !event.shiftKey && !event.altKey) {
event.preventDefault();
}
