selectMatch 上的 angular ui-bootstrap typeahead 回调? [英] angular ui-bootstrap typeahead callback on selectMatch?

问题描述

我正在使用 angular ui-bootstrap typeahead，我想用它作为选择许多选项的一种方式，所以我需要在 selectMatch 方法启动时获取选定的值，但我找不到如何在我的控制器中做到这一点

<预>型号:{{selected|json}}</pre><input type="text" ng-model="selected" typeahead="state for state in states | filter:$viewValue">

如果我查看选定的值，每次按下一个键时我都会得到更改...

scope.$watch('selected', function(newValue, oldValue) {... });

我知道 selectMatch 方法是在用户按 Enter 键或单击列表时调用的方法，但我不知道如何对此进行回调...

谢谢！

解决方案

现在有更好的方法来做到这一点.添加了新的回调方法

在控制器文件中添加以下内容:

 $scope.onSelect = function ($item, $model, $label) {$scope.$item = $item;$scope.$model = $model;$scope.$label = $label;};

在视图中添加以下内容:

请参阅typeahead 规范更多信息(搜索 onSelect).

I'm using the angular ui-bootstrap typeahead and I would want to use it as a way to pick up many choices, so I'd need to get the selected value when selectMatch method is launched but I can't find how to do that in my controller

<div class='container-fluid' ng-controller="TypeaheadCtrl">
<pre>Model: {{selected| json}}</pre>
<input type="text" ng-model="selected" typeahead="state for state in states | filter:$viewValue">

If I watch the selected value, I got the change every time a key is pressed...

scope.$watch('selected', function(newValue, oldValue) {... });

I got that the method selectMatch is the one which is called when the user press enter or click on the list but I don't know how to have a callback on that...

Thanks !

解决方案

There is better way of doing this now. A new callback method has been added

In controller file add the following:

 $scope.onSelect = function ($item, $model, $label) {
    $scope.$item = $item;
    $scope.$model = $model;
    $scope.$label = $label;
};

In view add the following:

 <input type="text"
        ng-model="selected"
        typeahead="state for state in states | filter:$viewValue"
        typeahead-editable="false"
        typeahead-on-select="onSelect($item, $model, $label)"/>

See the typeahead spec for more information (search for onSelect).
