django-autocomplete-light和棱角:角度如何获得所选择的值。

Using django-automcomplete-light V3 and angular on a non admin page.
Using the widget autocomplete.ModelSelect2

在非管理页面上使用django-automcomplete-light V3和angle。使用小部件autocomplete.ModelSelect2

Where is the selected value stored? Using firebug, it's not in a new hidden html element and if i attempt to watch the original (now hidden) select element, it's value never changes if I change the selected value in the autocomplete widget.

选择的值存储在哪里?使用firebug，它不在一个新的隐藏的html元素中，如果我尝试查看原始的(现在隐藏的)select元素，如果我更改autocomplete小部件中所选的值，那么它的值不会改变。

How can angular watch/read this value?

角式手表如何读取这个值?

Update:
As @visegan below points out you can use jquery syntax to get the value but for some reason you can't watch it.

更新:正如下面的@visegan所指出的，您可以使用jquery语法来获取该值，但是由于某些原因，您不能观看它。

i.e. this watch never gets triggered:

也就是说，手表永远不会被触发:

$scope.$watch(function(){
    return $('#id_field').val();
    },
    function(newVal, oldVal){
        console.log('current %r', newVal);
        $scope.models.foo=parseInt(newVal);
});

Well I have just tried with my project and it was pretty straight forward:

我刚刚尝试了我的项目，非常直接:

$('#id_field').val()

To be honest, I am also not sure where exactly does the value come from.

老实说，我也不确定这些价值到底来自哪里。

As for the change watcher: autocomplete light now uses select2 component, which is apparently a bit problematic with angular. There are two approaches that works: first one is to add more jquery:

至于变化观察者:自动补全光现在使用select2组件，这显然有点问题。有两种方法是有效的:第一种是添加更多jquery:

$('#id_field').change(function() {alert('changed')});

This I have tested. The other approach is to do it somehow natively. Look at Select2 event handling with Angular js

我已经测试了。另一种方法是以某种天生的方式去做。看看带有角度js的Select2事件处理
