Angular Material: md-button ~ hoot 根据 NodeRed 上的输入更改按钮的文本

Question

在 NodeRed 中，我使用新的 UI_Dashboard 模板节点，它对按钮等使用正常的 Angular Material 符号，我有以下工作按钮：

<md-button
ng-style="{background: msg.payload=='0' ?'green':'red'}"
ng-click="msg.payload = (msg.payload=='0' ? send({payload: 'event,allsprinkleroff'}) : send({payload: 'event,allsprinkleroff'})) "
> Button Name

但是，我希望 'Button Name' 根据传入的 msg.payload 值进行更改。现在有什么想法吗？我在这里的所有谷歌搜索和搜索都没有给我答案？（新手）

<div ng-controller="AppCtrl" ng-cloak="" ng-app="MyApp">
  <md-button ng-style="{background: msg.payload=='0' ?'green':'red'}" ng-click="msg.payload =(msg.payload=='0' ? send({payload: 'event,allsprinkleroff'}) : send({payload:'event,allsprinkleroff'})) ">Payload {{msg.payload}}</md-button>

  <br>
  <md-button ng-click="togglePayLoad()">Toggle Payload</md-button>
</div>

JS

angular.module('MyApp',['ngMaterial', 'ngMessages'])

.controller('AppCtrl', function($scope) {
  $scope.msg = {
    payload: 0
  }

  $scope.togglePayLoad = function () {
    $scope.msg.payload = ($scope.msg.payload === 0) ? 1 : 0;
  }
});
