Angular ng-options发送数组值

Angular ng-options sending array values

本文关键字：数组 ng-options Angular      更新时间：2023-09-26

我试图在我写的简单表单上使用AngularJS。对my使用ng-options，但是在验证表单时，我从select中收到的值是我在数组中选择的范围，而不是我在

表单中选择的实际字符串。
<section id="signin" ng-controller="Sign_in">
    <form method="post" action="xxxx.php">
      <div id="contact"> 
    <div class="input_label user"> 
      <label for="country">Pays</label>
    </div> 
    <select ng-options="country for country in countries" name="country" ng-model="Country"></select>
      </div> 
      <br>
      <input type="submit">
    </form>
</section>

下面是Angular代码

angular.module('commande',[]).controller('Sign_in',function Sign_in($scope, $element) {
$scope.countries = [
    "Afghanistan","Afrique du Sud","Albanie","Algérie","Allemagne","Andorre","Angola","Antigua et Barbuda","Arabie saoudite","Argentine","Arménie",

由于某些原因，你不能使用数组的值作为使用ngOptions进行选择的值。你必须这样做:

<select name="country" ng-model="Country" >
    <option ng-repeat="country in countries" value="{{country}}">
       {{country}}
    </option>
</select>

如果您还想设置Country的值，则将ng-selected添加到选项标签中，例如

<option ng-repeat="country in countries" value="{{country}}" ng-selected="country == Country">
   {{country}}
</option>

我认为你需要应用一个过滤器来获取值。

如果我是你，我会使用优秀的angular-ui typeahead指令，它与Boostrap 3一起工作。你的代码应该是:

  <input type="text" ng-model="selected" typeahead="country for country in countries | filter:$viewValue | limitTo:8" class="form-control">
