Activate the submission button on AngularJS once a correctly formatted email is provided

Currently working on an AngularJS demo to better understand its functionalities. The next task on my list is to enable the submit button only when a valid email address is entered. I'm seeking guidance on how to approach this and what concepts I need to grasp to make it work. Examples or suggestions would be highly appreciated.

This is the current setup:

I have a ui-view:

<div ui-view></div>

Within this view, I load my main template:

app.config:

   $stateProvider
        .state('route1', {

            url: "/ID/:slug",
            templateUrl: "/static/sign_up.html",
            controller: "myData"
        })

The 'myData' function just handles some ajax calls.

Template sign_up.html:

<h1>{{ data.name }}</h1>
<form action="">
        <div class="row">
            <div class="col-lg-6">
                <div class="form-group">
                    <label class="col-lg-3 control-label" for="id_email">Email
                    *</label>

                    <div class="col-lg-9">
                        <input class="form-control" id="id_email" name="email"
                        type="text">
                    </div>
                </div><button class="btn btn-lg" type="submit">Submit</button>
            </div>
        </div>
    </form>

Answer №1

If you're looking for information on how to validate email in AngularJS, I recommend checking out this link. It provides helpful examples and detailed documentation:

http://docs.angularjs.org/api/ng.directive:input.email

The process is straightforward - simply name your form 'MyForm' (or any other desired name) and when an input field with type="email" within this form contains a valid email address, myForm.$error.email changes to false. You can then easily configure your submit button by utilizing ng-disabled as shown below:

<button class="btn btn-lg" type="submit" ng-disabled="myForm.$error.email">Submit</button>

By default, ng-disabled = true, and it will only switch to enabled status once a valid email address is present.

Make sure to explore the documentation and examples provided,

Hopefully, you find this information useful,
