javascript - Confirm box cancel function does the same thing as OK -


i tell me why cancel button redirects me youtube instead of cancelling out operation.

function link(){     var r = confirm("are leaving?");     if (r = true) {         a.link("http://www.youtube.com");}     else {         return true;}     }

<a href="http://www.youtube.com" onclick="link()">youtube</a>

because omission of 1 equal sign, set r true here:

if (r = true) {

just change to:

if (r == true) {

or

if (r === true) {

or to

if (r) {
