How to detect when the focus is on a Div?


I'am working on a dynamic form that generates a number of Divs. I would like to detect if the focus was lost from the entire div not just from one input.

As the picture shows , I have multiple identical forms , the issue here is how to detect if the user is done editing one of the forms?

The forms are created dynamically using an ng-repeat.

<fieldset  data-ng-repeat="response in responces" ng-init="sectionIndex = $index" >
    <div id="customFrom">
    <input type="text" ng-model="response.code" name="" placeholder="Code">
    <input type="text" ng-model="response.rank" name="" placeholder="{{ 'app.forms.responses.rank' | translate }}" >
    <input type="text" ng-model="response.value" name="" placeholder="{{ 'app.forms.responses.value' | translate }}">
    <input type="text" ng-model="" name="" placeholder="{{ '' | translate }}" class="labelTextQuestionCreation">
    <button class="remove"  ng-click="removeResponse($index)" ng-show="deteteResponceOption">-</button>

What is the best way to add an action when the users jumps from one form to another? I need to detect when a form (Div) lost the focus in order to execute a function. Thank You.

Based on your problem, the best solution is to use ng-model-options.

Each element with ng-model will need the following attribute:

ng-model-options="{ updateOn: 'blur' }"

Then will look like:

<input type="text" ng-model="response.code" name="" ng-model-options="{ updateOn: 'blur' }" placeholder="Code">

With the ng-model-options, the model is only updated when the focus is lost on the form field. You can then have a $watch statement, which is only triggered when the model is updated.

In the $watch callback, when a change to any attributes of the main array if detected, you can run the models through validation to know if all the data is filled out and proceed with the execution of the desired function.

$scope.$watch('responces', function (newVal, oldVal) {
    // onBlur triggered an update to an attribute of **responces**
    // run your input validation here
}, true);
