deferred.catch()
Add handlers to be called when the Deferred object is rejected.
.deferred.catch(failFilter)🡢 Promise
failFilter
| Function | A function that is called when the Deferred is rejected. |
deferred.catch( fn ) is an alias to deferred.then( null, fn ). Read its page for more information.
Since the jQuery.get method returns a jqXHR object, which is derived from a Deferred object, we can add rejection handlers using the .catch method.
HTML
$.get("test.php")
.then(function () {
alert("$.get succeeded");
})
.catch(function () {
alert("$.get failed!");
});
