问题描述
我有这种对象格式
{
first_name : "Bob",
last_name : "Smith",
addresses : [
{address:"1 Baker Street",
city: "london"
},
{address:"2 Baker Street",
city: "london"
}
]
}
我想在选择下拉列表中设置地址位，即贝克街1号"，贝克街2号"
I want to set the address bits in the select dropdown i.e. "1 Baker Street", "2 Baker Street",
这是我的代码
<!DOCTYPE html>
<html>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.8/angular.min.js"></script>
<body>
<div ng-app="myApp" ng-controller="myCtrl">
<select ng-model="selectedAddress" ng-options="item for item in testObject">
</select>
</div>
<script>
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.testObject = {
first_name : "Bob",
last_name : "Smith",
addresses : [
{address:"1 Baker Street",
city: "london"
},
{address:"2 Baker Street",
city: "london"
}
]
}
});
</script>
</body>
</html>

I'm struggling to get my head around how to loop through the objects with AngularJS. Any help?
推荐答案
您必须调用array的子对象和属性.看一下这段代码.
You have to call the child object of array and the property. Take a look this code.
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope) {
$scope.testObject = {
first_name : "Bob",
last_name : "Smith",
addresses : [
{address:"1 Baker Street",
city: "london"
},
{address:"2 Baker Street",
city: "london"
}
]
}
});
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="myApp" ng-controller="myCtrl">
<select ng-model="selectedAddress" ng-options="item.address for item in testObject.addresses">
</select>
</div>
