如何在没有 Jquery-ui 且没有 Bootstrap 的情况下在 angularjs 中创建自定义进度条？

Question

我正在尝试在Angularjs 中创建进度条，但使用jquery-ui 创建进度条。现在我试图在没有jquery-ui 并且仅在angular 中实现相同的目标。

但它不起作用。下面是我的代码，你能帮我吗？

html

<div ng-app="app" ng-controller="main">
    <div progressbar="value"></div>
    <select ng-model="value" ng-options="item as item + '%' for item in items">
        <option value="">-- Select current progress --</option>
    </select>
</div>

脚本

angular.module("app", [])
.controller("main", ['$scope', function($scope) {
    $scope.value = 10
    $scope.items = [0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100]
}])
.directive('progressbar', [function() {
    return {
        restrict: 'A',
        scope: {
            'progress': '=progressbar'
        },
        controller: function($scope, $element, $attrs) {
            $element.progressbar({
                value: $scope.progress
            })

            $scope.$watch(function() {
                $element.progressbar({value: $scope.progress})
            })
        }
    }
}])

Answer 1

您只需要使用一些 CSS 和 HTML 来实现这一点。 $scope.value 将发挥所有作用。在我的回答中，我使用了链接而不是控制器，因为不习惯使用控制器进行 DOM 操作。我试过用两种方式回答这个问题。

1. HTML 5 <progress > 标签
2. 传统方式

我从在线资源中获取了这个例子，所以 CSS 可以是任何你的主题

angular.module("app", [])
.controller("main", ['$scope', function($scope) {
    $scope.value = 10
    $scope.items = [0, 10, 20, 30, 40, 50, 60, 70, 80, 90, 100]
}])
.directive('progressbar', [function() {
    return {
        restrict: 'A',
        scope: {
            'progress': '=progressbar'
        },
        link: function($scope, $element, $attrs) {
           
        }
    }
}])
