Promise alternative

in Using jQuery • 5 years ago

Hi! I'm using promises but have to find a jQuery alternative to make it crossbrowser compatible.

How do I have to change that return new Promise(function(resolve)... ?

I'm at the very first time getting in contact with promises, no idea how to use a deferred object to get that running..

 return ABCREQUEST($.extend(config, {
  part: params.A
}), apiParameter)
.then(function (data) {
  return new Promise(function (resolve) {
    parseInfo(data, config, function (isOk, responseData) {
      resolve(itemBuild$(config, responseData)[0]);
    });
  });
});

I could tell you to learn jQuery’s version. But I would rather use a polyfill to make native promises work with older browsers

Thank you.

I'd be interested in a jQuery solution as this is my task.

How would it look like?

It was good talking to you.

function promise(f) {
var def = jQuery.Deferred()
f(def.resolve, def.reject);
return def;
}
promise(function(resolve,reject) {
setTimeout(function() {
resolve(1, 2, 4);
},5000)
}).then(console.log)

Now you can use jQuery deferred similar to how you would use native Promise.
