in JavaScript, how to wrap a promise in timeout?

Question

It\'s a common pattern to implement timeout of some asynchronous function, using deffered/promise:

// Create a Deferred and return its Promise
function timeout(f         


        

Answer 1

function timeout(funct, args, time) {
    var deferred = new jQuery.Deferred(),
        promise = funct.apply(null, args);

    if (promise) {
        $.when(promise)
            .done(deferred.resolve)
            .fail(deferred.reject)
            .progress(deferred.notify);
    }

    setTimeout(function() {
        deferred.reject();
    }, time);

    return deferred.promise();
}
