JavaScript承诺句柄404

Question

I have this code:

promise.success(function (data) {

            //do something

}).fail(function() {
    //handle 404, don't let the browser log it
});

The url is fine, but if the user doesn't exist, the api is returning a 404 error (on purpose).

Browser logs the error... is it possible to avoid it and display different message?

Answer 1

The browser's dev tools will always display the failed request, however you can recover from a rejected promise by returning a value in the "fail" callback.

See here .

UPDATE

promise.success(function (data) {
    //do something
}).fail(function() {
    return true; // or return { error: true, reason: "some reason" };
});
