使用$compile绑定HTML内容时,AngularUI引导轮播无法正常工作

2019-11-11 07:37:54 作者：互联网

AngularUI Bootstrap version ^2.4.22

AngularJS version 1.6.4

Angular Sanitize version ^1.6.1

我在使用AngularUI引导程序的Carousel插件时遇到问题.在我的场景中,我需要读取一个包含一些模板路径的外部文件,并将每个文件作为幻灯片加载.请参见下面的示例：

index.html(正在调用指令的位置)

     <body id="body" ng-app="homePage">
        <div id="miolo">
            <div example-directive class="ng-hide"></div>
            <div banner-rotativo></div>
            <div id="menu-footer"></div>
        </div>
     </body>

banner-rotativo.directive.js-基本上,在此指令中,我有一个遵循AngularUI Bootstrap’s demo结构的模板,并且将响应数据绑定到$scope.slides数组.当我将$compile(objResponseInner)($scope)结果推入htmlContent属性时,轮播行为正常,但是将[[object HTMLDivElement]]和类似的东西呈现为一个项目.

angular.module('homePage')
.directive('bannerRotativo', ['$compile', '$http', 'moduleUrl', '$templateRequest', function ($compile, $http, moduleUrl, $templateRequest) {
    return {
        template:   '<div style="height: 305px" ng-controller="bannerHomeController" class="" >\
                        <div uib-carousel active="active" interval="myInterval" no-wrap="noWrapSlides">\
                            <div uib-slide ng-repeat="slide in slides track by slide.id" index="slide.id">\
                                <div ng-bind-html="slide.htmlContent">\
                                </div>\
                            </div>\
                        </div>\
                    </div>',

        link: function (scope, element, attributes, controller) {

            //Carousel
            scope.myInterval = 5000;
            scope.noWrapSlides = false;
            scope.active = 0;
            scope.slides = [];
            var intCurrentIndex = 0;

            $http({
                method: 'GET',
                url: moduleUrl.getUrl('homepage', '../config/banner-rotativo.conf')
            }).then(function success(objResponse, status, headers, config) {
                var objData = objResponse.data;
                if (objData.slides) {
                    angular.forEach(objData.slides, function (objItem, strObjectName) {
                        var strTemplatePath = moduleUrl.getUrl('homepage', '..' + objItem.caminho);
                        if (strTemplatePath) {
                            $templateRequest(strTemplatePath).then(function success(objResponseInner) {
                                var objContent = $compile(objResponseInner)(scope);
                                scope.slides.push({
                                    htmlContent: objContent,
                                    id: intCurrentIndex++
                                });
                            });
                        }
                    });
                }
            });
        }
    }


}]);

banner-rotativo.conf

{
"slides": {
    "banner-ex-one": {
        "titulo": "exone",
        "caminho-imagem": "assets/one.jpg",
        "caminho": "/html/components/banner-rotativo/banner-ex-one.view.html"
    },
    "banner-ex-two" : {
        "titulo": "extwo",
        "caminho-imagem": "assets/two.jpg",
        "caminho": "/html/components/banner-rotativo/banner-ex-two.view.html"
    },
    "banner-rav" : {
        "title": "rav",
        "caminho-imagem": "assets/rav.jpg",
        "caminho": "/html/components/banner-rotativo/banner-rav.view.html"
    },
    "banner-aviso" : {
        "title": "Quadro de comunicações 1",
        "caminho-imagem": "assets/aviso.jpg",
        "caminho": "/html/components/banner-rotativo/banner-aviso.view.html"
    },
    "banner-custom" : {
        "title": "Quadro de comunicações 2",
        "caminho-imagem": "assets/custom.jpg",
        "caminho": "/html/components/banner-rotativo/banner-custom.view.html"
    }
  }
}

加载的模板示例：

<div id="frameOne" ng-controller="slideOneController" class="varejo-clique-promocao-one" title="Conteúdo Varejo - Quadro One">
<div class="item">
    <div id="dados">

        <!-- Imagem banner one -->
        <img id="one" ng-click="enviarFormOne()" class="one" alt="" ng-if="1==1" ng-src="caminhoImagem"
        />
        <!-- End imagem banner -->
        <span ng-if="hasText">{{bannerText}}</span>
    </div>
    <div id="excecao" class="excecao" ng-if="typeof(one.excecao) !== 'undefined'">
        DEU EXCECAO
    </div>
    <div class="carousel-title" id="tituloOne" ng-if="1==1" title="{{bannerTitle}}">
        {{bannerTitle}}
    </div>
</div>

一些要点：

>我正在使用$compile,因为我注入的模板也具有控制器.如果我不使用它,则不会处理我的控制器.当我简单地插入没有$compile的HTML时,它就可以了.

怎么了？

解决方法:

问题是ng-bind-html需要html字符串,而您从$compile获得的结果实际上是元素对象.您可以从已编译的元素中获取HTML字符串,然后传递该字符串,但是这样做可能会遇到种种麻烦.

但是实际上您可以通过使用ngInclude而不是ng-bind-html来跳过$compile的麻烦.它将为您处理模板请求和编译.

因此,无需请求和编译strTemplatePath,而是将其存储到幻灯片列表中：

var strTemplatePath = moduleUrl.getUrl('homepage', '..' + objItem.caminho);
if (strTemplatePath) {
    scope.slides.push({
        htmlUrl: strTemplatePath,
        id: intCurrentIndex++
    });
}

然后在模板中使用它：

<div uib-slide ng-repeat="slide in slides track by slide.id" index="slide.id">
    <div ng-include="slide.htmlUrl"></div>
</div>

这是一个有点奏效的小提琴：jsfiddle.net,尽管我不得不在这里和那里填写一些空白.
