enhancing angular directives with data binding while replacing HTML content inside the compile function

Question

enhancing angular directives with data binding while replacing HTML content inside the compile function

I am currently attempting to develop a directive that will substitute an input field with a custom-made input field. Unfortunately, I am encountering challenges with getting the data binding to function properly, as the model does not display in the directive input field.

To showcase my issue, I have set up a jsFiddle:

http://jsfiddle.net/6HcGS/392/

It seems like I am missing something essential for the data binding to operate correctly:

tElement.replaceWith('<input ng-model="ngModel" type="text" />');

If anyone can provide assistance, I would greatly appreciate it, as this problem has consumed my entire day.

Cheers!

Answer №1

tElement.replaceWith('<input ng-model="ngModel" type="text" />');

When working with AngularJS, it's important to remember that ngModel needs to be recognized as a binding and not just a string. To ensure this, you can refer to the updated jsfiddle example here: http://jsfiddle.net/6HcGS/393/

An even simpler approach is to remove the isolated scope in the directive as demonstrated in this revised jsfiddle: http://jsfiddle.net/6HcGS/394/.

As mentioned by lort, attributes are passed to the element during replacement, but only if isolated scope is not being used.

I'm not sure what your intentions are, but it appears that the code snippet below may be all you require:

angular.module('accordionModule', [])
.directive('accordion', function(){
    return {
      restrict: 'A',
      replace: true,
      template: '<div></div>',
    }
});

In this example, the initial div element is replaced with another div. The functionality of binding through ng-model remains intact as the other attributes on the element are preserved during replacement.
