如何展示＆＃34;找不到匹配＆＃34;在角度ui？

标签： javascript angularjs angular-ui-bootstrap

我想要做的是：当用户开始输入打印头输入并且没有找到匹配时，它应该显示一条消息，说明＆＃34;找不到匹配＆＃34;。

下面是代码和一个plunker：

HTML 

<html ng-app="ui.bootstrap.demo">
  <head>
    <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.5.5/angular.js"></script>
    <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.5.5/angular-animate.js"></script>
    <script src="//angular-ui.github.io/bootstrap/ui-bootstrap-tpls-2.0.2.js"></script>
    <script src="example.js"></script>
    <link href="//netdna.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet">
  </head>
  <body>
<script type="text/ng-template" id="customTemplate.html">
  <a>
      <img ng-src="http://upload.wikimedia.org/wikipedia/commons/thumb/{{match.model.flag}}" width="16">
      <span ng-bind-html="match.label | uibTypeaheadHighlight:query"></span>
  </a>
</script>

<div class='container-fluid typeahead-demo' ng-controller="TypeaheadCtrl">

    <h4>Custom templates for results</h4>
    <pre>Model: {{customSelected | json}}</pre>
    <input type="text" ng-model="customSelected" placeholder="Custom template" uib-typeahead="state as state.name for state in statesWithFlags | filter:{name:$viewValue}" typeahead-template-url="customTemplate.html" class="form-control" typeahead-show-hint="true" typeahead-min-length="0">

</div>
  </body>
</html>

的JavaScript 

angular.module('ui.bootstrap.demo', ['ngAnimate', 'ui.bootstrap']);
angular.module('ui.bootstrap.demo').controller('TypeaheadCtrl', function($scope, $http) {

  var _selected;

  $scope.selected = undefined;
  $scope.states = ['Alabama', 'Alaska', 'Arizona', 'Arkansas', 'California', 'Colorado', 'Connecticut', 'Delaware', 'Florida', 'Georgia', 'Hawaii', 'Idaho', 'Illinois', 'Indiana', 'Iowa', 'Kansas', 'Kentucky', 'Louisiana', 'Maine', 'Maryland', 'Massachusetts', 'Michigan', 'Minnesota', 'Mississippi', 'Missouri', 'Montana', 'Nebraska', 'Nevada', 'New Hampshire', 'New Jersey', 'New Mexico', 'New York', 'North Dakota', 'North Carolina', 'Ohio', 'Oklahoma', 'Oregon', 'Pennsylvania', 'Rhode Island', 'South Carolina', 'South Dakota', 'Tennessee', 'Texas', 'Utah', 'Vermont', 'Virginia', 'Washington', 'West Virginia', 'Wisconsin', 'Wyoming'];
  // Any function returning a promise object can be used to load values asynchronously
  $scope.getLocation = function(val) {
    return $http.get('//maps.googleapis.com/maps/api/geocode/json', {
      params: {
        address: val,
        sensor: false
      }
    }).then(function(response){
      return response.data.results.map(function(item){
        return item.formatted_address;
      });
    });
  };

  $scope.ngModelOptionsSelected = function(value) {
    if (arguments.length) {
      _selected = value;
    } else {
      return _selected;
    }
  };

  $scope.modelOptions = {
    debounce: {
      default: 500,
      blur: 250
    },
    getterSetter: true
  };

  $scope.statesWithFlags = [{'name':'Alabama','flag':'5/5c/Flag_of_Alabama.svg/45px-Flag_of_Alabama.svg.png'},{'name':'Alaska','flag':'e/e6/Flag_of_Alaska.svg/43px-Flag_of_Alaska.svg.png'},{'name':'Arizona','flag':'9/9d/Flag_of_Arizona.svg/45px-Flag_of_Arizona.svg.png'},{'name':'Arkansas','flag':'9/9d/Flag_of_Arkansas.svg/45px-Flag_of_Arkansas.svg.png'},{'name':'California','flag':'0/01/Flag_of_California.svg/45px-Flag_of_California.svg.png'},{'name':'Colorado','flag':'4/46/Flag_of_Colorado.svg/45px-Flag_of_Colorado.svg.png'},{'name':'Connecticut','flag':'9/96/Flag_of_Connecticut.svg/39px-Flag_of_Connecticut.svg.png'},{'name':'Delaware','flag':'c/c6/Flag_of_Delaware.svg/45px-Flag_of_Delaware.svg.png'},{'name':'Florida','flag':'f/f7/Flag_of_Florida.svg/45px-Flag_of_Florida.svg.png'},{'name':'Georgia','flag':'5/54/Flag_of_Georgia_%28U.S._state%29.svg/46px-Flag_of_Georgia_%28U.S._state%29.svg.png'},{'name':'Hawaii','flag':'e/ef/Flag_of_Hawaii.svg/46px-Flag_of_Hawaii.svg.png'},{'name':'Idaho','flag':'a/a4/Flag_of_Idaho.svg/38px-Flag_of_Idaho.svg.png'},{'name':'Illinois','flag':'0/01/Flag_of_Illinois.svg/46px-Flag_of_Illinois.svg.png'},{'name':'Indiana','flag':'a/ac/Flag_of_Indiana.svg/45px-Flag_of_Indiana.svg.png'},{'name':'Iowa','flag':'a/aa/Flag_of_Iowa.svg/44px-Flag_of_Iowa.svg.png'},{'name':'Kansas','flag':'d/da/Flag_of_Kansas.svg/46px-Flag_of_Kansas.svg.png'},{'name':'Kentucky','flag':'8/8d/Flag_of_Kentucky.svg/46px-Flag_of_Kentucky.svg.png'},{'name':'Louisiana','flag':'e/e0/Flag_of_Louisiana.svg/46px-Flag_of_Louisiana.svg.png'},{'name':'Maine','flag':'3/35/Flag_of_Maine.svg/45px-Flag_of_Maine.svg.png'},{'name':'Maryland','flag':'a/a0/Flag_of_Maryland.svg/45px-Flag_of_Maryland.svg.png'},{'name':'Massachusetts','flag':'f/f2/Flag_of_Massachusetts.svg/46px-Flag_of_Massachusetts.svg.png'},{'name':'Michigan','flag':'b/b5/Flag_of_Michigan.svg/45px-Flag_of_Michigan.svg.png'},{'name':'Minnesota','flag':'b/b9/Flag_of_Minnesota.svg/46px-Flag_of_Minnesota.svg.png'},{'name':'Mississippi','flag':'4/42/Flag_of_Mississippi.svg/45px-Flag_of_Mississippi.svg.png'},{'name':'Missouri','flag':'5/5a/Flag_of_Missouri.svg/46px-Flag_of_Missouri.svg.png'},{'name':'Montana','flag':'c/cb/Flag_of_Montana.svg/45px-Flag_of_Montana.svg.png'},{'name':'Nebraska','flag':'4/4d/Flag_of_Nebraska.svg/46px-Flag_of_Nebraska.svg.png'},{'name':'Nevada','flag':'f/f1/Flag_of_Nevada.svg/45px-Flag_of_Nevada.svg.png'},{'name':'New Hampshire','flag':'2/28/Flag_of_New_Hampshire.svg/45px-Flag_of_New_Hampshire.svg.png'},{'name':'New Jersey','flag':'9/92/Flag_of_New_Jersey.svg/45px-Flag_of_New_Jersey.svg.png'},{'name':'New Mexico','flag':'c/c3/Flag_of_New_Mexico.svg/45px-Flag_of_New_Mexico.svg.png'},{'name':'New York','flag':'1/1a/Flag_of_New_York.svg/46px-Flag_of_New_York.svg.png'},{'name':'North Carolina','flag':'b/bb/Flag_of_North_Carolina.svg/45px-Flag_of_North_Carolina.svg.png'},{'name':'North Dakota','flag':'e/ee/Flag_of_North_Dakota.svg/38px-Flag_of_North_Dakota.svg.png'},{'name':'Ohio','flag':'4/4c/Flag_of_Ohio.svg/46px-Flag_of_Ohio.svg.png'},{'name':'Oklahoma','flag':'6/6e/Flag_of_Oklahoma.svg/45px-Flag_of_Oklahoma.svg.png'},{'name':'Oregon','flag':'b/b9/Flag_of_Oregon.svg/46px-Flag_of_Oregon.svg.png'},{'name':'Pennsylvania','flag':'f/f7/Flag_of_Pennsylvania.svg/45px-Flag_of_Pennsylvania.svg.png'},{'name':'Rhode Island','flag':'f/f3/Flag_of_Rhode_Island.svg/32px-Flag_of_Rhode_Island.svg.png'},{'name':'South Carolina','flag':'6/69/Flag_of_South_Carolina.svg/45px-Flag_of_South_Carolina.svg.png'},{'name':'South Dakota','flag':'1/1a/Flag_of_South_Dakota.svg/46px-Flag_of_South_Dakota.svg.png'},{'name':'Tennessee','flag':'9/9e/Flag_of_Tennessee.svg/46px-Flag_of_Tennessee.svg.png'},{'name':'Texas','flag':'f/f7/Flag_of_Texas.svg/45px-Flag_of_Texas.svg.png'},{'name':'Utah','flag':'f/f6/Flag_of_Utah.svg/45px-Flag_of_Utah.svg.png'},{'name':'Vermont','flag':'4/49/Flag_of_Vermont.svg/46px-Flag_of_Vermont.svg.png'},{'name':'Virginia','flag':'4/47/Flag_of_Virginia.svg/44px-Flag_of_Virginia.svg.png'},{'name':'Washington','flag':'5/54/Flag_of_Washington.svg/46px-Flag_of_Washington.svg.png'},{'name':'West Virginia','flag':'2/22/Flag_of_West_Virginia.svg/46px-Flag_of_West_Virginia.svg.png'},{'name':'Wisconsin','flag':'2/22/Flag_of_Wisconsin.svg/45px-Flag_of_Wisconsin.svg.png'},{'name':'Wyoming','flag':'b/bc/Flag_of_Wyoming.svg/43px-Flag_of_Wyoming.svg.png'}];

使用typeahead-no-results。将以下内容添加到您的输入

typeahead-no-results="noResults"

然后在下面添加以下内容。

<div ng-show="noResults">
   <i class="glyphicon glyphicon-remove"></i> No Match Found
</div>
