Modifying button text dynamically during save operation with AngularJS

Question

Modifying button text dynamically during save operation with AngularJS

Is it possible to dynamically change the text on a submit button while data is being saved in a form?

Here's an example of the button:

<button ng-click="save()">Save data</button>

I have updated my save function based on some suggestions I received:

    $scope.ButtonText = "Save day";
    $scope.save=function(){
        $scope.ButtonText = "Saving day";
        for(var i=0;i<days.length;i++)
        {
           MyService.saveday()
            .success(function(data, status, headers, config) {
            })
            .error(function(data, status, headers, config) {
            });
        }
       $scope.ButtonText = "Save day";
    };

During the process of saving data, I would like the text on the button to switch from "Save data" to "Saving data" and then back to "Save data" once all data has been saved.

UPDATE

I initially added

 $scope.ButtonText = "Save day";

following some responses, but I realized that my situation is more complex as I make multiple asynchronous service calls. So my question now is how can I update the text while these async calls are being made, and only revert it back after they are all complete.

Thanks,

Answer №1

To dynamically change the button text and update it while saving, you can expose the button text in the scope like this:

<button ng-click="save()">{{button}}</button>

Then, in your function:

$scope.button = "Save data";

$scope.save=function(){
    $scope.button = "Saving day";
    for(var i=0;i<days.length;i++)
    {
       MyService.saveday()
        .success(function(data, status, headers, config) {
        })
        .error(function(data, status, headers, config) {
        }).then(function() {
            if (i===days.length) { // check if it's the last iteration
                $scope.button = "Save day";
            }
        });
    }

};

There are multiple approaches to achieve this.

One method involves adding a new property to the scope, which will store the text for the button.

$scope.buttonText = 'Save';
$scope.save = function() {
    $scope.buttonText = 'Saving...';
};

Subsequently, rather than hardcoding the button text in the HTML, it is advisable to bind it to the newly created scope property.

<button ng-click="save()">{{buttonText}}</button>
