Angularjs。在datepicker中没有更新ng-model [英] Angularjs. ng-model is not being updated in datepicker

问题描述

我正在尝试编写jquery来使用隐藏的输入区域在文本点击上打开datepicker。这也是多个地方所必需的。

I was trying to write jquery to open datepicker on text click using hidden input area. Also this is required at multiple places.

以下是我的HTML。

<div class="date-format">
    <input class="hidden-date-picker" id="hidden-date1" type="hidden" ng-model="date1"/>
    <a href="" class="date-picker" id="date1">{{date1 | date: 'dd MMM yyyy a'}}</a>
</div>
<div class="date-format">
    <input class="hidden-date-picker" id="hidden-date2" type="hidden" ng-model="date2"/>
    <a href=""  class="date-picker" id="date2">{{date2 | date: 'dd MMM yyyy a'}}</a>
</div>

以下是javascript -

Following is javascript -

var app = angular.module('index-app', []);

app.controller('index-controller', function($scope) {
$scope.date1 = new Date(2016, 0, 1);
$scope.date2 = new Date();

$('.hidden-date-picker').each(function() {
    $(this).datepicker({
        changeYear: 'true',
        changeMonth: 'true',
        startDate: '07/16/1989',
        firstDay: 1,
        onSelect: function(dateText, inst) {
            console.log($scope.$eval($(this).attr('ng-model')));
            $scope.$eval($(this).attr('ng-model')).setTime(Date.parse(dateText));
            console.log($scope.date1);
        }
    });
});
$('.date-picker').each(function() {
    $(this).click(function (e) {
        $('#hidden-' + $(this).attr('id')).datepicker('show')
        e.preventDefault();
    });
});
});

从控制台输出中可以清楚地看到$ scope.date1在从日历中选择日期时被修改。但这种变化并未在html方面得到反映。

It is clear from the console output that $scope.date1 is being modified on selecting the date from calender. But the change is not being reflected in the html side.

推荐答案

使用指令可以解决ng-model未更新的问题

Using a directive can resolve your problem of ng-model not updated

您的HTML代码

<input class="hidden-date-picker" id="hidden-date1" type="hidden" ng-model="date1" customzdatetime />

在输入代码中添加指令 customzdatetime 。

Add a directive 'customzdatetime' to your input tag.

app.directive('customzdatetime', function () {
    return {
        restrict: 'A',
        require: 'ngModel',
        link: function (scope, element, attrs, ngModelCtrl) {
            element.datetimepicker({
                debug: false,
                format: 'DD-MM-YYYY',
                maxDate: moment()
            }).on('dp.change', function (e) {
                ngModelCtrl.$setViewValue(e.date);
                scope.$apply();
            });
        }
    };
});
