angular.js - angular-daterangepicker cannot obtain model value

Question

I wrote a demo based on the documentation, put it into the production environment and tested it and found that the model value could not be obtained. Has anyone who also used this plug-in encountered similar problems? I would like to ask for advice.

github: https://github.com/fragaria/a...

HTML:

<p ng-controller="AppCtrl">
    <input date-range-picker class="form-control date-picker" type="text" ng-model="date" options="{
        timePicker: true,
        timePickerIncrement: true,
        timePicker24Hour: true,
        timePickerSeconds: true,
        locale: {
            applyLabel : '确定',  
            cancelLabel : '取消',  
            fromLabel : '起始时间',  
            toLabel : '结束时间',  
            customRangeLabel : '自定义',  
            daysOfWeek : [ '日', '一', '二', '三', '四', '五', '六' ],  
            monthNames : [ '一月', '二月', '三月', '四月', '五月', '六月', '七月', '八月', '九月', '十月', '十一月', '十二月' ],  
            format: 'YYYY-MM-DD HH:mm:ss'
        }
    }"/>
    <a href="javascript:;" ng-click="getDate()">save</a>
</p>

JS:

var app = angular.module('test',['daterangepicker']);

app.config(function($interpolateProvider,$httpProvider, $controllerProvider, $compileProvider, $filterProvider, $provide){
 
});

app.controller('AppCtrl',function($scope,$http){

    $scope.getDate = function(){
        console.log($scope.date);
    }

    $scope.$watch('date', function(newDate) {
        console.log('New date set: ', newDate);
    }, false);

});

angular.bootstrap(document,['test']);

Answer 1

This may be caused by the mechanism in js where objects are references and values ​​are copied

Try mounting the bound variables on an object

Like the code in github

exampleApp.controller('TestCtrl', function ($scope) {
    $scope.datePicker.date = {startDate: null, endDate: null};
}
