Jquery:如何在Angular strap datetimepicker值更改上放置侦听器

Jquery: How to put a listener on Angular strap datetimepicker value change?

本文关键字：侦听器 datetimepicker strap Angular Jquery      更新时间：2023-09-26

我必须倾听jquery 的角度带日期时间选择器值的变化

（无法在角度应用程序/控制器中添加代码或使用模糊代码）。

请提供一种只使用Jquery/JScript的方法。非常感谢

AngularStrap DatetimePicker文档

我尝试了什么

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

上述方法不起作用。另外，还有一件事是val()函数正在返回值，但当我试图从.attr('value')中获取值时，它就是undefined。

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

为什么不在日期更改时调用JavaScript函数呢。

  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())
      })
    })
  })

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);
};

每当值发生变化时，ng-change都会调用myChange。
