angularjs - 带有 ui-grid 问题的 ui-datepicker

Question

我正在尝试更新 ui-grid 中的 editableCellTemplate 以包含 ui-datepicker，因此我将允许用户有可能使用 firefox 或 IE 选择日期，但没有成功。这是我正在尝试做的事情，使用editableCellTemplate: '<div style="display:inline-block; min-height:290px; position:absolute;"><div uib-datepicker class="well well-sm" datepicker-options="dateOptions" ng-focus="open()" style="background-color: #f5f5f5; border: 1px solid #e3e3e3; border-radius: 0; padding: 8px;" >'

这是一个带有所有详细信息和选项的 ui-datepicker 指令的示例。您可以在此github 链接和此plunker示例中找到详细信息，其中 ui-datepicker 指令如下所示：

var app = angular.module('ui.grid.edit');

app.directive('uiGridEditDatepicker', ['$timeout', '$document', 'uiGridConstants', 'uiGridEditConstants', function($timeout, $document, uiGridConstants, uiGridEditConstants) {
return {
    template: function(element, attrs) {    
        var html = '<div class="datepicker-wrapper" ><input type="text" uib-datepicker-popup datepicker-options="datepickerOptions" datepicker-append-to-body="true" is-open="isOpen" ng-model="datePickerValue" ng-change="changeDate($event)" popup-placement="auto top"/></div>';
        return html;
    },
    require: ['?^uiGrid', '?^uiGridRenderContainer'],
    scope: true,
    compile: function() {
        return {
            pre: function($scope, $elm, $attrs) {
                if ($attrs.datepickerOptions){
                    if ($scope.col.grid.appScope[$attrs.datepickerOptions]){
                        $scope.datepickerOptions = $scope.col.grid.appScope[$attrs.datepickerOptions];

            },
