Loop over a generated form with fields using ng-repeat

I am facing an issue where I have an ng-repeat loop and I need to submit the values of input fields within it to a generated form. Using ng-model did not work for me. Is there a way to access the input names inside the form tag?

<li ng-repeat="group in tournament.groups">
    <form novalidate ng-submit="tournament.submit(group.team1, group.team2)">
        <span>
            {{ group.team1.name }}
            <input type="number" name="team1" placeholder="x">
        </span> - <span>
            <input type="number" name="team2" placeholder="x">
            {{ group.team2.name }}
        </span>

        <button type="submit">Save</button>
    </form>
</li>

Answer №1

It is important to bind the input using ng-model and ensuring that the name attribute of the form is included. Without the name attribute, your ng-submit will not be triggered.

By adding the name attribute to your form, such as name="team", Angular creates a new variable within scope containing all form-related information including validity status and field data.

HTML Markup Example:

<li ng-repeat="group in tournament.groups">
    <form name="team" novalidate ng-submit="tournament.submit(group.team1, group.team2)">
        <span>
            {{ group.team1.name }}
            <input type="number" name="team1" placeholder="x" ng-model="group.team1"/>
        </span> - <span>
            <input type="number" name="team2" placeholder="x" ng-model="group.team2"/>
            {{ group.team2.name }}
        </span>

        <button type="submit">Save</button>
    </form>
</li>

Implement ng-model for Two-way Data Binding:

In View:

<li ng-repeat="group in tournament.groups">
    <form novalidate ng-submit="submit()">
        <span>
            {{ group.team1.name }}
            <input type="number" name="team1" placeholder="x" ng-model="group.team1.name">
        </span> - <span>
            <input type="number" name="team2" placeholder="x" ng-model="group.team2.name">
            {{ group.team2.name }}
        </span>

        <button type="submit">Save</button>
    </form>
</li>

In Controller:

$scope.submit = function(){
   console.log($scope.group.team1.name);
   console.log($scope.group.team2.name);
};

Test out my code to retrieve the values effectively.

If you want to streamline your approach, I recommend consolidating multiple forms into one. You can achieve this by iterating within the form, like so:

<form name="team" novalidate ng-submit="tournament.submit(group.team1, group.team2)">
    <li ng-repeat="group in tournament.groups">

        <span>
            {{ group.team1.name }}
            <input type="number" name="team1" placeholder="x" ng-model="team1"/>
        </span> - <span>
            <input type="number" name="team2" placeholder="x" ng-model="team2"/>
            {{ group.team2.name }}
        </span>

        <button type="submit">Save</button>
   </li>
</form>

Make sure to update the ng-model for each group using '$index' (e.g., ng-model="team{{$index}}")

This adjustment should help optimize your process.
