Transmitting information after a delay when using ng-keyup in AngularJS

In my Angular app, I am using ng-keyup to search data from my backend. However, the issue is that it sends a request to the server with every key press. Is there a way to configure it to send a post request only after the user has paused or stopped typing? Or should I avoid using ng-keyup for this purpose?

Here is my HTML code:

<input ng-keyup="search(data)" ng-model="data" type="text"/>

This is the function in my controller:

$scope.search=function($scope, $http){
   ....insert HTTP post codes here...
}

If you need to delay updating a model in AngularJS, you can use the debounce option with ng-model.

Simply include

ng-model-options="{ debounce: 1000 }"

in your input field.

To implement a delayed search functionality in AngularJS, you can utilize the ng-change directive along with $timeout.

Note: It is important to inject both $http and $timeout into your controller if you are using $http as a parameter in your search method.

<input ng-change="search(data)" ng-model="data" type="text"/>

JavaScript code snippet

var handle;
$scope.search = function(data){
   if(handle){
        $timeout.cancel(handle);
        handle  = null;
    }
    handle = $timeout(function(){
       // Perform the $http post request here
    }, 1000);
};
