javascript - 我怎样才能用angularJS获得数据的东西属性

Question

我想访问 {{ test.data('something') }} 但它不起作用。

<select ng-model="test">
    <option data-something="mySomething" value="blahblah">blahblah</option>
</select>

有什么方法可以访问它吗？

我正在使用 angular 1.3.14(当前最新版本)

如果你只是把变量赋值给属性，你总是可以访问变量。这也是 angular 的用法:

Controller :

// Reference to mySomething
$scope.mySomething = "Some value";

查看:

<select ng-model="test">
    <option data-something="mySomething" value="blahblah">blahblah</option>
</select>

当您有多个选项(例如 ng-options)时，您可以执行以下操作:

Controller :

$scope.myOptions = [
    { mySomething: "Something", value: "1", text: "Value 1" },
    { mySomething: "Something else", value: "2", text: "Value 2"}
];

$scope.doSomething = function() {
    console.log($scope.test.mySomething);
}

查看:

<select ng-options="opt.value as opt.text for opt in myOptions"
        ng-model="test"
        ng-change="doSomething()">
</select>
