Angularjs dynamically set attribute

Question

I\'m trying to dynamically add attribute to div in controller in angular js.

 var table = document.getElementById(\"div_id\").setAttribute(\"ng-click\", \"f         


        

Answer 1

Angular2 is providing [attr.<attribute name>] to bind attribute values.

<div id="divID" [attr.role]="roleVal">
  This text color can be changed
</div>

In component class:

  addAttr() {
    this.roleVal = 'admin';
  }

  removeAttr() {
    this.roleVal = '';
  }

  checkAttr() {
    alert(this.roleVal);
  }

Answer 2

get element by id and set new attribute and value

 var el =angular.element('#divId');
 el.attr('attr-name', 'attr-value');

Answer 3

To Set attribute dynamically use

var myEl = angular.element(document.querySelector('#divID'));
myEl.attr('myattr',"attr val");

To get attribute value use

var myEl = angular.element( document.querySelector('#divID'));
alert(myEl.attr('myattr'));

To remove attribute use

var myEl = angular.element( document.querySelector( '#divID' ) );
myEl.removeAttr('myattr');

Answer 4

You need to recompile your div

var el = angular.element("div_id");
$scope = el.scope();
$injector = el.injector();
$injector.invoke(function($compile){
   $compile(el)($scope)
})
