动态添加Angular UI Datepicker

Adding Angular UI Datepicker dynamically

本文关键字：Datepicker UI Angular 添加 动态      更新时间：2023-09-26

在我的项目中，我需要向页面添加动态数量的日期拾取器。我试过这样做(普朗克):

脚本:

var app = angular.module('plunker', ['ui.bootstrap']);    
app.controller('MainCtrl', function($scope) {
  $scope.openDatePicker = function($event) {
    $event.preventDefault();
    $event.stopPropagation();
    $scope.opened = true;
  };
  $scope.dateOptions = {
    formatYear: "yy",
    startingDay: 1,
    format: "shortDate"
  };
  $scope.details = [{
    "parameterValue": "2015-08-12"
  }, {
    "parameterValue": "2015-08-12"
  }, {
    "parameterValue": "2015-08-12"
  }, {
    "parameterValue": "2015-08-12"
  }];
});
HTML: 

<!DOCTYPE html>
<html ng-app="plunker">
<head>
  <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.4.3/angular.js"></script>
  <script src="//ajax.googleapis.com/ajax/libs/angularjs/1.4.3/angular-animate.js"></script>
  <script src="//angular-ui.github.io/bootstrap/ui-bootstrap-tpls-0.13.3.js"></script>
  <link href="//netdna.bootstrapcdn.com/bootstrap/3.1.1/css/bootstrap.min.css" rel="stylesheet">
  <script src="script.js"></script>
</head>
<body>
  <div ng-controller="MainCtrl">
    <form name="detailsForm" novalidate ng-submit="submitForm(detailsForm.$valid)">
      <div ng-repeat="item in details" class="input-group">
        <input ng-model="item.parameterValue" type="text" class="form-control" id="datePickerItem" datepicker-popup="shortDate" 
        is-open="opened" datepicker-options="dateOptions" current-text="Today" clear-text="Clear" close-text="Close" ng-readonly="false" />
        <span class="input-group-btn">
      <button type="button" class="btn btn-default" ng-click="openDatePicker($event)"><i class="glyphicon glyphicon-calendar"></i></button>
    </span>
      </div>
    </form>
  </div>
</body>
</html>

问题是，当我试图打开一个日期选择器时，所有它们都被打开(逻辑上，因为它们共享相同的$scope.opened变量)。另外，当我关闭它们并试图再次打开它们时，什么也没有发生。

是否有一种优雅的方式来实现这一点?

谢谢。

所有的日期选择器都有id="datePickerItem"。

id属性在html中必须唯一。试试这个:

id="datePickerItem_{{$index}}"

这将把ng-repeat的当前索引添加到id中，因此您可以相对确定您的id是唯一的。这也可以防止所有的日期选择器在同一时间打开。

此外，您正在使用一个和相同的opened变量为所有日期拾取器。

试试这个:

<div ng-repeat="item in details" class="input-group">
    <input ng-model="item.parameterValue" type="text" class="form-control" 
        id="datePickerItem_{{$index}}" datepicker-popup="shortDate" 
        is-open="opened[$index]" datepicker-options="dateOptions" current-text="Today"
        clear-text="Clear" close-text="Close" ng-readonly="false" />
    <span class="input-group-btn">
        <button type="button" class="btn btn-default" ng-click="openDatePicker($event, $index)">
            <i class="glyphicon glyphicon-calendar"></i>
        </button>
    </span>
</div>

: 

$scope.opened = [];
$scope.openDatePicker = function($event, index) {
    $event.preventDefault();
    $event.stopPropagation();
    $scope.opened[index] = true;
};

只要确保你设置$scope.opened[index]为false，以防你关闭日期选择器

try this:

$scope.open = function($event,opened) {
        $event.preventDefault();
        $event.stopPropagation();
        $scope[opened] = true;
    };

和html

ng-click="open($event, 'nameOfYourModel')"

为什么不在repeat object上绑定opened呢?

:

<div ng-repeat="item in details" class="input-group">
    <input ng-model="item.parameterValue" type="text" class="form-control" 
        id="datePickerItem_{{$index}}" datepicker-popup="shortDate" 
        is-open="item['opened']" datepicker-options="dateOptions" current-text="Today"
        clear-text="Clear" close-text="Close" ng-readonly="false" />
    <span class="input-group-btn">
    <button type="button" class="btn btn-default" ng-click="openDatePicker($event, item)">
        <i class="glyphicon glyphicon-calendar"></i>
    </button>
</span>

和in控制器:

$scope.openDatePicker = function($event, item) {
    $event.preventDefault();
    $event.stopPropagation();
    if(item.opened){
        item.opened = !item.opened;
    } else{
        item.opened = true;
    }
};
