JavaScript重定向仅刷新页面

Question

I have a javascript function that looks like:

function logout() {

alert('logging out 2');
window.location.replace("http://stackoverflow.com");

}

The alert pops up but the page refreshes when I want it to go to stackoverflow.com (for testing purposes). Why would this be?

Answer 1

My guess is you are not cancelling the click event of the element that is calling the function so the page is refreshing. Cancel the click event.

onclick="logout(); return false;"

or use preventDefault

From the comments

$('#logout').click(function(e) {e.preventDefault(); logout(); });
