Calling angularjs scope function from href
I am using a library which appends a href element onto an tag. On this link I need to make a call to an angularjs function that is within scope. Something like...
<a href="{{someFunction()}}"></a>
Note: I am attaching this href via javascript from another library (nvd3.js) not actually writing this in because if I was I could easily use ng-click or ng-href.
Answer
So I was not pleased with the answer to this as it doesn't really utilize an elegant angular solution.
Here's my solution: http://jsfiddle.net/jjosef/XwZ93
HTML:
<body class="wrapper" ng-app="ExampleApp">
<a my-href="buildUrl('one', aVariable, 'three')">This is my a tag with a function that builds the url</a>
</body>
JS:
angular.module('ExampleApp', []);
angular.module('ExampleApp').run(function($rootScope) {
$rootScope.buildUrl = function() {
var link = [];
for(var i = 0; i < arguments.length; i++) {
link.push(arguments[i].toLowerCase());
}
return '/#!/' + link.join('/');
};
$rootScope.aVariable = 'two';
});
angular.module('ExampleApp').directive('myHref', function($parse) {
return {
restrict: 'A',
link: function(scope, element, attrs) {
var url = $parse(attrs.myHref)(scope);
element.attr('href', url);
}
}
});
