我想要console.log或者用angularjs来定位数组中对象的字符串，但是它不起作用。请帮帮我，我对angularjs还是个新手。
这就是我要做的。

<div class="container" ng-app="DetailApp">
<div ng-controller="PostController">
</div>
</div>
<script>
var app = angular.module('DetailApp', []);
app.controller('PostController', function($scope) {
$scope.details = [{firstname: "Dave", lastname: "Del Rio"}, {firstname: "Gerald", lastname: "Kingston"}, {firstname: "Larry", lastname: "Jackson"}];
if ($scope.details.firstname == "Dave Del Rio") {
console.log("Hello Dave!")
}
else {
console.log("sorry, You're not welcome!")
};
});
</script>
</body>
</html>我想在数组对象中指向名字“Dave”，但是它根本不起作用。

可以使用
Array#some检查数组中是否有任何元素与条件匹配。
