Changing the background color of a table cell with AngularJS

Looking for something equivalent to

this.style.backgroundColor = red;
in Angular. Tried $scope.style.backgroundColor but it didn't work. Any other options?

UPDATE:

To clarify, I want to change the color when a <td> element is clicked. It was straightforward with JS, but now I need to do it dynamically in Angular. Not sure how ng-style can assist me with this situation.

Answer №1

When it comes to making presentation changes, it's best practice to handle them within the view rather than the controller.

ng-style gives you the flexibility to assign AngularJS class objects that can be dynamically altered.

Take a look at this example snippet from the documentation:

<input type="button" value="set color" ng-click="myStyle={color:'red'}">
<input type="button" value="set background" ng-click="myStyle={'background-color':'blue'}">
<input type="button" value="clear" ng-click="myStyle={}">
<br/>
<span ng-style="myStyle">Sample Text</span>
<pre>myStyle={{myStyle}}</pre>

Edit:

If you need to conditionally apply ng-style based on function calls in your controller, here's how you can do it:

<td ng-style="{ background-color: clicked ? 'red' : 'black' }">

In your controller function:

var $scope.clicked = false;
var ChangeColor = function($index){ $scope.clicked = true; }

Remember, you can also conditionally apply pre-defined style classes using ng-class (check out this related question for examples).
