我有一个选择显示对象列表,一个按钮显示对象选择的数据。有用。
问题是我需要在选择框中显示多个对象名称,我试过这个但是它返回一个字符串而不是一个json对象:
<select ng-model="selected">
<option ng-repeat="item in items" value="{{item}}">
{{item.name}} <span>Some nice data</span>
</option>
</select>
我怎样才能得到它?我必须为它创建一个指令吗?
这里我的代码在没有附加数据的情况下工作到选择框中
var app = angular.module('app', []);
app.controller('Test', function($scope) {
$scope.selected = null;
$scope.items = [{
name: 'a',
value: 1,
something: "xyz"
}, {
name: 'b',
value: 2,
something: "xyz"
}, {
name: 'c',
value: 3,
something: "xyz"
}]
$scope.show = function() {
alert("selectec " + $scope.selected.name + ' with value ' + $scope.selected.value);
}
});

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<html ng-app="app">
<body>
<div ng-controller="Test">
<select data-ng-options="i.name for i in items" ng-model="selected">
</select>
<button ng-click="show()">press</button>
</div>
</body>
</html>

您无法从ngOptions
AngularJS指令输出HTML。
但是你可以使用一个函数来自定义选项内容来标记元素,就像这样(注意HTML被转义):
var app = angular.module('app', []);
app.controller('Test', function($scope) {
$scope.selected = null;
$scope.items = [{
name: 'a',
value: 1,
something: "xyz"
}, {
name: 'b',
value: 2,
something: "xyz"
}, {
name: 'c',
value: 3,
something: "xyz"
}]
$scope.show = function() {
alert("selectec " + $scope.selected.name + ' with value ' + $scope.selected.value);
}
$scope.format = function(i) {
return i.name + '<span>Some nice data</span>';
};
});
&#13;
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<html ng-app="app">
<body>
<div ng-controller="Test">
<select data-ng-options="i as format(i) for i in items" ng-model="selected">
</select>
<button ng-click="show()">press</button>
</div>
</body>
</html>

将HTML放在选项的选项标记内无效。您只需要使用DIV标签或任何适合您需求的标签来创建您自己的标签。另外请注意,您可能需要重新考虑您的UI,因为下拉的目的不是浏览数据
