can we add check undefined value in ng-init.? if there is value in scope then print it else print foobar. Currently, it should print foobar
can we add a condition in ng-init ?
here is my code http://plnkr.co/edit/bFbAWXq6dKdkxWAxp7v8?p=preview
<body ng-controller="MainCtrl" ng-init="test|| 'foobar'">
<p>Hello {{test}}!</p>
</body>
It's that simple:
<body ng-controller="MainCtrl" ng-init="test = test|| 'aasasas'">
<p>Hello {{test}}!</p>
</body>
You can write almost everything as you write in a Javascript expression/line.
var app = angular.module('plunker', []);
app.controller('MainCtrl', function($scope) {
});<script data-require="[email protected]" src="http://code.angularjs.org/1.2.0rc1/angular.js" data-semver="1.0.7"></script>
<div ng-app="plunker" ng-controller="MainCtrl" ng-init="test = test|| 'aasasas'">
<p>Hello {{test}}!</p>
</div>Yes you can add conditions in ng-init
<body ng-controller="MainCtrl" ng-init="test = test ? test: 'aasasas'">
<p>Hello {{test}}!</p>
</body>
the value of test will be test itself if its defined, otherwise 'aasasas'
