I have a background image on a div that I want to have switch on hover. I can't change the class because I'm using a bound property to fill in the information. As far as I know I don't see any way to add hover with styles inside of the html and I found a way to do it in jquery but it just doesn't seem like the angular way.

Method #1: No controller, everything in template.
<div ng-init="bg = ''"
ng-mouseenter="bg = 'http://www.gravatar.com/avatar/b76f6e92d9fc0690e6886f7b9d4f32da?s=100'"
ng-mouseleave="bg = ''"
style="background-image: url({{bg}});">
</div>
Method #2: Using vars to store the values (uses a controller)
<div ng-mouseenter="bg = imageOn"
ng-mouseleave="bg = imageOff"
style="background-image: url({{bg1}});">
</div>
Controller:
function myCtrl($scope){
$scope.bg1 = "" // this is the default image.
$scope.imageOn = "http://www.gravatar.com/avatar/b76f6e92d9fc0690e6886f7b9d4f32da?s=100";
$scope.imageOff = ""; // image that would after after the mouse off.
}
Method #3: Saved the best for last! Using a directive!!
<div hover-bg-image="{{image}}"></div>
Directive (could be improved to revert back to original image if there is one... its basic to show example):
.directive('hoverBgImage',function(){
return {
link: function(scope, elm, attrs){
elm.bind('mouseenter',function(){
this.style.backgroundImage = 'url('+attrs.hoverBgImage+')';
});
elm.bind('mouseleave',function(){
this.style.backgroundImage = '';
})
}
};
});
Controller:
function withDirective($scope){
$scope.image = "http://www.gravatar.com/avatar/b76f6e92d9fc0690e6886f7b9d4f32da?s=100";
}
Note: The items in the controllers could/should/would be set dynamically.
