Angular Directive: bind 'mouseover' event to an element

angularjs, bind, directive, events, javascript

Solution

The more "Angular" way of doing things would be to use `ng-mouseover`

You could put it in the "partial html" view

<my-customer 
    info="user"
    ng-mouseover="user.age = user.age + 1;"></my-customer>

`ng-mouseover` evals the expression within the Angular context. This ensures everything is within the Angular context and you never have to worry about triggering digests manually.

per @floriban

You could also put it within the directive template itself

<div ng-mouseover="customerInfo.age = customerInfo.age + 1;">
  <span>
    <label class="label-success">Username: {{customerInfo.username}}</label>
  </span>
  <span>
    <label class="label-default">{{customerInfo.address}}</label>
  </span>
  <span>
    <label class="label-danger">{{customerInfo.age}}</label>
  </span>
</div>

Problem

In my controller, I have the following array of users, which will be displayed by iteration in the partial html template in controller: ``` vm.users = [ {"username": "johnDoe", "address": "Saltlake City, UT", "age": 34}, {"username": "janeDoe", "address": "Denver, CO", "age": 33}, {"username": "patrickDoe", "address": "San Francisco, CA", "age": 35} ]; ``` partial html code: ``` <div ng-repeat="user in mapView.users"> <my-customer info="user"></my-customer></div> ``` myCustomer directive: I wish to increment the customer's age when the mouseover event happens on the customer. Is it possible to do this in the directive? ``` angular .module('angularApp') .directive('myCustomer', function() { return { restrict: 'E', link: function(scope, element) { element.bind('mouseover', function(e) { e.target.age++; // this is not working, need help here! console.log(e.target, 'mouseover'); }); }, scope: { customerInfo: '=info' }, templateUrl: 'views/directives/myCustomer.html' }; }); //myCustomer ``` myCustomer template: ``` <span> <label class="label-success">Username: {{customerInfo.username}}</label> </span> <span> <label class="label-default">{{customerInfo.address}}</label> </span> <span> <label class="label-danger">{{customerInfo.age}}</label> </span> ```
