And*_*res 2 javascript select angularjs
我有一个选择显示对象列表和一个按钮来显示对象选定的数据.有用.
问题是我需要在选择框中显示超过对象名称,我试过这个但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>
我怎么才能得到它？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 ' + $scope.selected.value);
}
});<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<html ng-app="app">
<body>
<div ng-controller="Test">
<select data-ng-options="i.name for i in items" ng-model="selected">
</select>
<button ng-click="show()">press</button>
</div>
</body>
</html>您无法从ngOptionsAngularJS指令输出HTML .但您可以使用函数来自定义选项内容以标记元素,如下所示(请注意HTML已转义):
var app = angular.module('app', []);
app.controller('Test', function($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>';
};
});<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>
