How to set angular json model into css

Question

I have this code being generated somewhere else in the application

"PHcolour":"rgb(4, 31, 156)","Ctextcolour":"rgb(59, 214, 252)"

I'm getting the data fine (from the model), using the squiggly brackets {{CtextColour}}

I'm wanting to have a button on my page that could change the colour scheme of the site. I have this working for something else using ng-click

Now the issue i'm having is the css won't accept the {{}} So the method i was trying to do it was like this

<style media="screen">
.custom { background-color: #fff; }
.custom h1 { color: {{Ctextcolour}}; }
.custom h2 { color: {{Ctextcolour}}; }
.custom h3 { color: {{Ctextcolour}}; }
.custom h4 { color: {{Ctextcolour}}; }
.custom h5 { color: {{Ctextcolour}}; }
.custom h6 { color: {{Ctextcolour}}; }
.custom p { color: {{Ctextcolour}}; }
.custom th { background-color: #c3cced; color: {{Ctextcolour}};}
.custom.panel-heading { background-image:-webkit-linear-gradient(top, #c3cced, #c3cced ) !important; color: {{Ctextcolour}} !important;}
</style>

Which did not work (and also turned the rest of my html code pink in my IDE (Atom)

I tried switching it over to this which removed the pink, But still didn't work!

<ng-style media="screen">
.custom { background-color: #fff; }
.custom h1 { color: {{Ctextcolour}}; }
.custom h2 { color: {{Ctextcolour}}; }
.custom h3 { color: {{Ctextcolour}}; }
.custom h4 { color: {{Ctextcolour}}; }
.custom h5 { color: {{Ctextcolour}}; }
.custom h6 { color: {{Ctextcolour}}; }
.custom p { color: {{Ctextcolour}}; }
.custom th { background-color: #c3cced; color: {{Ctextcolour}};}
.custom.panel-heading { background-image:-webkit-linear-gradient(top, #c3cced, #c3cced ) !important; color: {{Ctextcolour}} !important;}
</ng-style>

The html for the button is this:

<button type="button" class="btn btn-info" ng-click="colorScheme = 'custom'" ng-model="eventData.theme">Custom Theme
    </button>

The inspect element shows nothing has been added to the button, There is also no javascript errors at all.

Thanks

Look at the documentation page for ngStyle. This is how you can use it:

HTML

<p ng-style="myStyle">Text</p>
<button ng-click="set()">set</button>
<button ng-click="clear()">clear</button>

Controller

$scope.data = {"PHcolour":"rgb(4, 31, 156)","Ctextcolour":"rgb(59, 214, 252)"};

$scope.set = function(){
    $scope.myStyle = { color: $scope.data.Ctextcolour } 
};

$scope.clear = function(){
    $scope.myStyle = undefined; 
};

See plunker.

Can you update your question with a link to a jsFiddle or plnker?

ng-style works as html style, you can add properties to an element. But you cant generate new css class.

You can check ngStyle official doc

I recommend you this post and i let you and example on this snippet

<!doctype html>
<html lang="en" ng-app="myApp">
<head>
  <meta charset="UTF-8">
  <title>Document</title>
  
  <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.8/angular.min.js"></script>

  <link rel="stylesheet" href="//netdna.bootstrapcdn.com/bootswatch/3.0.0/united/bootstrap.min.css">
  
  <style>
    .original {
      background-color: red;
    }
  </style>

  <script>

  var myApp = angular.module('myApp', []);


  myApp.controller("myAppCtrl", ["$scope", "$document", function($scope, $document) {

      $scope.colors = ['#C1D786', '#BF3978', '#15A0C6', '#9A2BC3'];

      $scope.style = function(value) {
          return { "background-color": value };
      }

  }]);


  </script>

</head>
<body>

<div ng-controller="myAppCtrl">
 <h4 class="original" > hi! i have the original class</h5>
    
  <h4 class="original" ng-style="style(colors[0])"> hi! i am the first color in array</h5>
  <h4 class="original" ng-style="style(colors[1])"> hi! i am the second color in array</h5>


</div>

</body>
</html>
