Compiling an element with AngularJS and sharing its scope

Let me explain a straightforward directive:

<div my-directive>
    <span ng-click="reveal()">Click Me</span>
    <!-- More content goes here -->
</div>

Whenever I click on Click Me, it triggers a modal that displays a form for editing some information. All the details in this form are part of the scope.form data. Let's assume there is only one element named name within this object.

This is how I implemented it in my directive:

scope.reveal = function()
{
   var el = $compile('<input type="text" ng-model="scope.form.name" />')(scope);

   // Modal initialization code
}

The modal pops up successfully with the correct value of

scope.form.name</code. However, upon closing and reopening the modal, the value isn't retained (meaning, the <code>scope.form.name
remains unaltered within the directive).

What would be the most effective way to address this issue?

Answer №1

When working with angularjs, it is customary not to compile and append elements to the DOM directly. Instead, it is recommended to define your form within the template and use ng-show to bind a property on the scope for toggling the visibility of the form.

<div my-directive>
    <span ng-click="form.show = true">Click Me</span>
    <form ng-show="form.show">
        <input type="text" ng-model="form.name" />
    <form>
</div>
