Looking to enhance my application with Google WebKit functionality. My goal is to create a feature similar to Gmail's where hovering over the "+" symbol expands to display options such as "insert photos" and "insert links". I'm just starting out with AngularJS, so any assistance would be highly valued.
If you want to create an expanding element on mouse hover and shrink on mouse leave, you can utilize the ng-mouseenter and ng-mouseleave directives with a custom directive like the one below:
myApp.directive('expando', function () {
return {
restrict: 'A',
scope: {
},
controller: ['$scope', function ($scope) {
$scope.open = false;
}],
link: function ($scope, elem, attrs, ctrl) {
$scope.toggleState = function () {
if ($scope.open) {
$scope.open = false;
} else {
$scope.open = true;
}
};
},
replace: true,
transclude: true,
template: '<div ng-mouseenter="toggleState()" ng-mouseleave="toggleState()"> <span ng-hide="open" class="sectionIndicator">+</span> <div ng-show="open" class="inline" ng-transclude></div> </div>'
};});
This directive should fulfill your requirements. You can see an example in action in this fiddle - http://jsfiddle.net/LukeMaso/LwFws/
Utilize ngMouseover, ngMouseleave and ngGlass for a basic effect:
