Jquery: 如何在 Angular 表带 datetimepicker 值更改时设置监听器？

Question

我必须聆听 angular 表带日期时间选择器值从 jquery

的变化

(不能在angular application/controllers中添加代码或使用anuglar代码).

请提供一种仅使用 Jquery/JScript 的方法。非常感谢

AngularStrap DatetimePicker Documentation

我试过的

$("#datepk").bind('input', function(){alert('value changed');})

$("#datepk").bind('change', function(){alert('value changed');})

$("#datepk").bind('DOMSubtreeModified', function(){alert('value changed');})

以上方法无效。此外，还有一件事是 val() 函数正在返回值，但是当我尝试从 .attr('value') 获取值时，它是 undefined.

$("#datepk").val(); /// nicely retruning the value
$("#datepk").attr('value'); /// returning undefined

Answer 1

我认为以下几点会对您有所帮助。

将 ng-change 添加到您的输入中。

<input id="datepk" type="text" class="form-control" ng-model="selectedDate" name="date" bs-datepicker ng-change="myChange()">

并在您的控制器中添加：

$scope.myChange= function(){
      console.log($scope.selectedDate);
};

ng-change 每次值改变时都会调用myChange。

Answer 2

为什么不在日期更改时调用 JavaScript 函数。

  var myapp = angular.module('myapp', ['ngAnimate', 'mgcrea.ngStrap']);
  myapp.config(function($datepickerProvider) {
    angular.extend($datepickerProvider.defaults, {
      dateFormat: 'dd/MM/yyyy',
      startWeek: 1
    })
  });

  myapp.controller('myctrl', ['$scope', '$datepicker',
    function($scope, $datepicker) {
      $scope.selectedDate = "2016-04-28T09:57:58.274Z"; // <- [object Date]
      $scope.selectedDateAsNumber = 509414400000; // <- [object Number]
      $scope.fromDate = "2016-04-08T18:30:00.000Z"; // <- [object Date]
      $scope.untilDate = ''; // <- [object Undefined]

    }
  ]);


  $(document).ready(function() {
    $("#datepk").on("click", function() {
      $(".datepicker table tr td").on("click tap", function(event) {
        alert($("#datepk").val())
      })
    })
  })
