The Angular-ui typeahead feature is delivering accurate results when the backspace key is pressed

I've been using Angular-UI typeahead and it's been working fine, but I've noticed a strange behavior when I hit the backspace key - it gives the correct results.


For example, if I type

sector 4

The result is

Sector 1
Sector 2
Sector 4
Sector 5

However, when I press backspace, the correct result is shown as

Sector 4
Sector 42
Sector 42a
Sector 47

This is my HTML code:

<input class="location-input" ng-model="Constants.loc" typeahead="loc.title for loc in loc_getdat()" typeahead-min-length="1">

And here is my controller code:

$scope.loc_getdat = function() {
if ($scope.Constants.loc.length > 1) {
    return $http.get('/api/v2/location_auto_suggest?loc=' + $scope.Constants.loc)
        .then(function(response) {
            return response.data.location_search
        });
    } 
}

What am I doing wrong?

Answer №1

Resolved the issue. I identified that the delay in displaying results for typeahead was causing the problem. The server was taking some time to respond, so I made a modification in the library file where the typeahead was initialized with a delay of 0 milliseconds. I decided to adjust the typeaheadWaitMs setting from 0 to 50.

(k.typeaheadWaitMs)||50

After applying this change, everything is now functioning smoothly.
