How to set body attribute in css using angularjs?

Tags: javascript,jquery,html,css,angularjs

Problem :

I'm setting the background image of a page using :

body {
    background: url( no-repeat center center fixed;
    -webkit-background-size: cover;
    -moz-background-size: cover;
    -o-background-size: cover;
    background-size: cover;
    text-align: center;

I would like to read a property from a scoped variable in my controller that looks like this:


How can I set this css body attribute from within my .html page ? In jQuery I could .css(). Can I do something similar using angulalJs? doesn't seem to detail this ?

I'm trying this fiddle but does not work :

fiddle code :

<body ng-style="getBodyStyle()">

$scope.getBodyStyle = function () {
    return {background: "url( no-repeat center center fixed;"};

Solution :

You need an app & controller before you can do anything- your JSFiddle is failing because you've got no controller, and you never define $scope.

You can create a $scope variable called $scope.bodyStyle in a controller, like this:

app.controller('MainCtrl', function($scope) {
 $scope.bodyStyle = {background: "url(    content/uploads/2013/06/space.jpg) no-repeat center center fixed"};

And then register the app & the controller in the mark-up like this:

<html ng-app="plunker">

<body ng-controller="MainCtrl" ng-style="bodyStyle">
 Demo text


I made a Plunkr showing the whole app, because JSFiddle is a pain with Angular.

Angular needs to start with a lot more pieces working together than regular JS or JQuery- it can be confusing when you get started, so I recommend starting out with the AngularJS seed app.

You mention that you want to get the background image from a $scope variable. You could do that like this:

app.controller('MainCtrl', function($scope) {
  $scope.bodyStyle = {background: "url(" + $scope.image + ") no-repeat center center fixed"};
