How can I make angularjs ngChange handler be called only when user finishes typing

Use ng-model-options in Angular > 1.3

 <input type="text"         ng-model="vm.searchTerm"         ng-change="vm.search(vm.searchTerm)"         ng-model-options="{debounce: 750}" />

Without ng-model-options -- In markup:

<input ng-change="inputChanged()">

In your backing controller/scope

var inputChangedPromise;$scope.inputChanged = function(){    if(inputChangedPromise){        $timeout.cancel(inputChangedPromise);    }    inputChangedPromise = $timeout(taskToDo,1000);}

Then your taskToDo will only run after 1000ms of no changes.

As of Angular 1.3, you could use Angular ng-model-options directive

<input ng-change="inputChanged()" ng-model-options="{debounce:1000}">

Write your own directive- this will only run the commands on myText based on the conditions you set

<input my-change-directive type="text ng-model="myText" />.directive('myChangeDirective',function() {    return {        require : 'ngModel',        link : function($scope,$element,$attrs) {            var stringTest = function(_string) {                //test string here, return true                //if you want to process it            }            $element.bind('change',function(e) {                 if(stringTest($attrs.ngModel) === true) {                    //make ajax call here                    //run $scope.$apply() in ajax callback if scope is changed                }            });        }    }})
