AngularJS按钮单击绑定值以输入

Question

我正在用AngularJS创建一个数字键盘，在其中输入字段可以通过按数字按钮或手动输入一个值来接收输入值。

我的控制器代码：

app.controller('LoginFormController', ['$scope', function($scope){
    $scope.numPass = [];

    $scope.num = function(number){
        $scope.numPass.push(number);
        $scope.input = $scope.numPass;
        console.log(number)
    };
}]);

我的HTML模板代码：

<form class="login-form" ng-controller="LoginFormController">
<div class="d-flex flex-row justify-content-center" >
    <div class="col-5">
        <input ng-model="input" type="password" class="form-control" placeholder="Login">
    </div>
</div>
<div class="row d-flex flex-row justify-content-center">
    <div class="btn-group-vertical numpad mx-4 my-3" role="group" aria-label="Basic example">
        <div class="row d-flex-flex-row justify-content-center">
            <div class="btn-group btn-group-lg">
                <button type="button" ng-click="num(1)" class="btn btn-outline-secondary border-bottom-0 num-blue">1</button>
                <button type="button" class="btn btn-outline-secondary border-bottom-0 num-blue">2</button>
                <button type="button" class="btn btn-outline-secondary border-bottom-0 num-blue">3</button>
            </div>
        </div>
        <div class="row d-flex-flex-row justify-content-center">
            <div class="btn-group btn-group-lg">
                <button type="button" class="btn btn-outline-secondary border-bottom-0 num-blue">4</button>
                <button type="button" class="btn btn-outline-secondary border-bottom-0 num-blue">5</button>
                <button type="button" class="btn btn-outline-secondary border-bottom-0 num-blue">6</button>
            </div>
        </div>
        <div class="row d-flex-flex-row justify-content-center">
            <div class="btn-group btn-group-lg">
                <button type="button" class="btn btn-outline-secondary num-blue">7</button>
                <button type="button" class="btn btn-outline-secondary num-blue">8</button>
                <button type="button" class="btn btn-outline-secondary num-blue">9</button>
            </div>
        </div>
        <div class="row d-flex-flex-row justify-content-center">
            <div class="btn-group btn-group-lg">
                <button type="button" class="btn btn-outline-secondary num-blue">0</button>
                <button type="button" class="btn btn-outline-secondary red-arrow"><img class="img-fluid" src="images/web_images/Arrow-Left-Icon.png" alt=""></button>
                <button type="button" class="btn btn-outline-secondary red-arrow"><img class="img-fluid" src="images/web_images/Arrow-Left-Double-Icon.png" alt=""></button>
            </div>
        </div>
    </div>
</div>
<div class="row d-flex flex-row">
        <div class="col-12 justify-content-center btn-group submit-buttons btn-group-lg">
            <button type="button" class="col-2 btn btn-cancel">Cancel</button>
            <button type="submit" class="col-3 btn-clock-in btn btn-primary">Clock In<img class="img-fluid" src="images/web_images/clock-in-icon.png" alt="Clock In"></button>
            <button type="submit" class="col-2 btn btn-force">Force</button>
        </div>
</div>

这有点奏效，但我相信有更好的方法来实现。 无需创建数组，然后将数组绑定到输入字段。

Answer 1

乍一看，可以改进的地方。

我将使用ngRepeate来显示键盘。 例如：

 function keypadNumber($scope) {
  $scope.keypad = [{number: 1}, {number: 2}, {number: 3}];
}



<div class="row d-flex-flex-row justify-content-center">
  <div class="btn-group btn-group-lg">
    <button ng-repeat="(key, value) in keypad" ng-click="keypadNumber({keypad.number})">{{keypad}}</button>
  </div>
</div>

Answer 2

导致我的onclick不能绑定到输入字段的问题是我将它们传递给数组，而不是传递给空字符串。

 $scope.numPass = [];

当我应该一直使用它时

 $scope.numPass = '';
