Deactivate button after a set period of time

Question

Deactivate button after a set period of time

Using angularjs, I have a button to create tickets that works with an http request to call a PHP web service. The problem is that the http request has a delay of x seconds, allowing users to click multiple times during this delay resulting in multiple tickets being created but only one actually working. To solve this issue, I need to add a delay to the button itself. However, I am struggling to make this work. Please review the code and note that the solution should be implemented outside of the request. Here is the link to the jsfiddle for reference: jsfiddle

Angular offers a special $timeout service component specifically for this purpose:

$timeout(function() {
    $scope.betDelay=false;
}, 1000);

One key benefit of using the $timeout utility is that it automatically handles dirty model checking, a task that would not be executed when utilizing the standard window.setTimeout() function.

In essence, Angular does not continuously monitor if changes have been made to the $scope; instead, it only checks at critical stages in the lifecycle of a component, and $timeout facilitates your connection with this lifecycle.

Refer to the updated JSFiddle link: http://jsfiddle.net/Lt7aP/862/

Alternatively, you can explicitly instruct the $scope to perform dirty checking through $apply(). For example,

setTimeout(function() {
    $scope.betDelay=false;
    $scope.$apply();
}, 1000);

From what I gather from your message, it seems that the user has the capability to repeatedly click on the login button, resulting in multiple duplicate entries being made as the API does not have enough time to check for existing records due to the rapid succession of hits.

To tackle this issue, we can implement a mechanism to verify if the button has already been clicked. Establish a variable named $scope.isButtonClicked and initialize it as false. Upon each click event, check if it is currently set to false. If it is indeed false, then switch it to true before proceeding with the request.

function LoginController($scope) {
    $scope.isButtonClicked = false;
    $scope.login = function () {
        if ($scope.isButtonClicked === false) {
            $scope.isButtonClicked = true;
            var request = $http({
                dataType: 'json',
                method: "post",
                url: "/xxx.php",
                data: {
                    data1: $scope.data1,
                    data2: $scope.data2
                },
                headers: { 'Content-Type': 'application/json' }
            });
            request.success(function (data) {
                /* I attempted to introduce a delay at the top but encountered issues with its functionality */
            });
        }
    };
}
