我在Angular指令中使用bootstrap-daterangepicker时遇到了麻烦。它在最初加载页面时工作正常，但是当切换页面/状态（我使用ui-router）并返回带有daterangepicker的页面时，插件不再起作用。
它抛出了这个错误：
TypeError：$（...）。daterangepicker不是函数
似乎插件在更改状态时已自行删除。任何人都知道如何解决这个问题？
app.directive("daterangepicker", function() {
return {
restrict: "A",
scope: false,
link: function($scope, $element, $attr){
$($element).daterangepicker({
format: "DD.MM.YYYY",
startDate: moment().subtract('days', 1),
endDate: new Date(),
buttonClasses: ['btn-primary'],
}, function(from, to) {
$scope.date = {from: from, to: to};
$scope.$apply(); // I need apply() here to use the two-way-databinding
});
}
}
});

我会避免重新发明轮子，已经有几个项目提供了指令，使用https://angular-ui.github.io/bootstrap/
导入模块：
angular.module（＆＃39; myModule＆＃39;，[＆＃39; ui.bootstrap＆＃39;]）;
并使用它：
<!doctype html>
<html ng-app="ui.bootstrap.demo">
<head>
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.5.3/angular.js"></script>
<script src="//ajax.googleapis.com/ajax/libs/angularjs/1.5.3/angular-animate.js"></script>
<script src="//angular-ui.github.io/bootstrap/ui-bootstrap-tpls-1.3.2.js"></script>
<script src="example.js"></script>
<link href="//netdna.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css" rel="stylesheet">
</head>
<body>
<style>
.full button span {
background-color: limegreen;
border-radius: 32px;
color: black;
}
.partially button span {
background-color: orange;
border-radius: 32px;
color: black;
}
</style>
<div ng-controller="DatepickerPopupDemoCtrl">

<h4>Popup</h4>
<div class="row">

控制器：
angular.module('ui.bootstrap.demo', ['ngAnimate', 'ui.bootstrap']);
angular.module('ui.bootstrap.demo').controller('DatepickerPopupDemoCtrl', function($scope) {
$scope.today = function() {
$scope.dt = new Date();
};
$scope.today();
$scope.clear = function() {
$scope.dt = null;
};
$scope.inlineOptions = {

$scope.dateOptions = {
dateDisabled: disabled,
formatYear: 'yy',
maxDate: new Date(2020, 5, 22),

startingDay: 1
};
// Disable weekend selection
function disabled(data) {
var date = data.date,
mode = data.mode;
return mode === 'day' && (date.getDay() === 0 || date.getDay() === 6);
}
$scope.toggleMin = function() {
$scope.inlineOptions.minDate = $scope.inlineOptions.minDate ? null : new Date();
$scope.dateOptions.minDate = $scope.inlineOptions.minDate;
};
$scope.toggleMin();
$scope.open1 = function() {
$scope.popup1.opened = true;
};
$scope.open2 = function() {
$scope.popup2.opened = true;
};
$scope.setDate = function(year, month, day) {
$scope.dt = new Date(year, month, day);
};
$scope.formats = ['dd-MMMM-yyyy', 'yyyy/MM/dd', 'dd.MM.yyyy', 'shortDate'];
$scope.format = $scope.formats[0];
$scope.altInputFormats = ['M!/d!/yyyy'];
$scope.popup1 = {
opened: false
};
$scope.popup2 = {
opened: false
};
var tomorrow = new Date();
tomorrow.setDate(tomorrow.getDate() + 1);
var afterTomorrow = new Date();
afterTomorrow.setDate(tomorrow.getDate() + 1);
$scope.events = [{
date: tomorrow,
status: 'full'

function getDayClass(data) {
var date = data.date,

if (mode === 'day') {
var dayToCheck = new Date(date).setHours(0, 0, 0, 0);
for (var i = 0; i < $scope.events.length; i++) {
var currentDay = new Date($scope.events[i].date).setHours(0, 0, 0, 0);

}
}
}
return '';
}
});

我终于找到了解决问题的方法！
要明确：angular-daterangepicker插件发生了同样的错误。
实际上是因为某些其他依赖项加载了额外的jQuery。因为这个加载了多个jQuerys，这导致了bug。
答案 2 :(得分：3)
尝试在初始化daterangepicker中的directive之前添加此内容。
if (!jQuery().daterangepicker) {
return;
}
$($element).daterangepicker({...});
