jquery - 如何在 Angular Material 中显示下拉列表

标签 jquery css angularjs drop-down-menu

我是 Angular Material 的新手。所以我正在尝试使用有 Angular Material 来制作表格。我能够显示输入字段。由于它没有值，字段名称将看起来像占位符，如果用户单击输入字段，字段名称将设置为标题并能够输入值。

我正在尝试显示与 Material 输入字段相同的下拉菜单。最初，如果没有选择任何值，字段名称将看起来像占位符，右上角有箭头。如果用户单击下拉字段，则需要将字段名称设置为标题并打开下拉列表。

我试过了，但我在下拉菜单中遇到了一些问题。

<form name="pForm" role="form">
<!--Personal Info Col-->    
<div class="row form-row1">
<div class="col-sm-4" ng-class="{ 'has-error': (pForm.fname.$dirty || pForm.$submitted) && pForm.fname.$invalid }" >

<input class="form-control" type="text" name="aname" ng-model="model.aname" required/>
<span class="highlight"></span>
<span class="bar"></span>
<label class="control-label l_font field-name" for="aname"> Name of Account *</label>

最佳答案

您的代码似乎没有使用 angular-material 标签，您混淆了 jquery 和 angular，

要使用带 Angular Material ，请为 Angular Material 添加必要的引用

 <link data-require="angular-material@0.11.0" data-semver="0.11.0" rel="stylesheet" href="https://ajax.googleapis.com/ajax/libs/angular_material/0.11.0/angular-material.min.css" />
  <script data-require="jquery@*" data-semver="2.1.4" src="http://code.jquery.com/jquery-2.1.4.min.js"></script>
  <script data-require="angular.js@*" data-semver="1.4.5" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.4.5/angular.min.js"></script>
  <script data-require="angular-material@0.11.0" data-semver="0.11.0" src="https://ajax.googleapis.com/ajax/libs/angular_material/0.11.0/angular-material.min.js"></script>
  <script data-require="angular-animate@1.4.1" data-semver="1.4.1" src="https://code.angularjs.org/1.4.1/angular-animate.js"></script>
  <script data-require="angular-aria@1.4.1" data-semver="1.4.1" src="https://code.angularjs.org/1.4.1/angular-aria.js"></script>

并将 ngMaterial 作为依赖项注入(inject)到您的模块中，

var app = angular.module('app', ["ngMaterial"]);

SELECT 演示

// Code goes here


var app = angular.module('app', ["ngMaterial"]);

app.controller('myCtrl', function($scope) {
      $scope.categories = [
            "test1 with 001" ,
            "test2 with 002" 
            ];
      $scope.Print = function(){
        alert($scope.model);
      }
      
  
});
