How to get the content out of an editable div in angularjs

Question

I am trying to get the content out of an editable div. But i am stuck at implementing the angular template for it.

I am not sure how to map model data from html template to angular controller.

<div ng-repeat="todo in todos">                 
    <div class="todo.id" ng-model={{ ? }} contenteditable="true">
        <pre>{{ todo.text }}</pre>                          
    </div>
    <button type="button" class="btn btn-link"
        ng-click="editTodo(todo.id)">Edit</button>
</div>

I want to pass whatever text i have under

<div class="todo.id"></div>

Since my div is under ng-repeat, i cannot set ng-model to one scope variable.

What should i have within "ng-model={{ ? }}". Or is there a workaround for such a scenario.

Please guide me on this.

I have added more desc. Hope its clear now. I dont know what to write within 'ng-model' so that i can pass the value within a particular div, to angular controller. — jsbisht

To make a div content editable in angular, you need to create a contenteditable directive.

There is an example for this in the angular documentation here:

https://docs.angularjs.org/api/ng/type/ngModel.NgModelController#custom-control-example

and a great blog entry from Gabo Esquivel on the topic here: http://gaboesquivel.com/blog/2014/in-place-editing-with-contenteditable-and-angularjs/

As you can see in Gabriel's example, the code for such a directive would be like this (I've added some comments to better understand whats going on):

app.directive("contenteditable", function() {
  return {
    require: "ngModel",
    link: function(scope, element, attrs, ngModel) {

      //read the text typed in the div (syncing model with the view)
      function read() {
        ngModel.$setViewValue(element.html());
      }

      //render the data now in your model into your view
      //$render is invoked when the modelvalue differs from the viewvalue
      //see documentation: https://docs.angularjs.org/api/ng/type/ngModel.NgModelController#
      ngModel.$render = function() {
        element.html(ngModel.$viewValue || "");
      };

      //do this whenever someone starts typing
      element.bind("blur keyup change", function() {
        scope.$apply(read);
      });
    }
  };
});

Good luck!

Thanks for that. I am too new too understand all that. I will learn more and try that out :)

I highly recommend that you learn directives, services, and factories. They are the real powerhouses behind Angular. Dan Wahlin has great video tutorials on how to create directives. I highly recommend looking into them.

@user3527354 I got this working now. I guess that implementing a directive for a div type is mandatory to be editable(unlike input tag). Thanks alot.
