AngularUI Bootstrap 使用 $compile 绑定 HTML 内容时轮播无法正常工作
AngularUI Bootstrap Carousel not working properly when binding HTML content with $compile
AngularUI Bootstrap version ^2.4.22
AngularJS version 1.6.4
Angular Sanitize version ^1.6.1
我在使用 AngularUI Bootstrap 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,并将它们中的每一个加载为幻灯片。请参见下面的示例:
index.html(调用指令的地方)
<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,在这个指令中,我有一个遵循 AngularUI Bootstrap's demo 结构的模板,我正在绑定响应数据到 $scope.slides
数组。当我推入 htmlContent
属性 结果 $compile(objResponseInner)($scope)
时,轮播行为正常,但它呈现 [[object HTMLDivElement]] 和类似的东西作为一个项目。
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++
});
});
}
});
}
});
}
}
}]);

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 HTML 而没有 $compile
时,它呈现正常。
怎么了?
问题是 ng-bind-html
需要 html 字符串,而您给它的结果是 $compile
实际上是一个元素对象。您 可以 从编译的元素中获取 HTML 字符串并传递它,但是您可能 运行 会因此遇到各种麻烦。
但是您实际上可以通过使用 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,与其请求和编译 strTemplatePath
,不如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:
<div uib-slide ng-repeat="slide in slides track by slide.id" index="slide.id">
<div ng-include="slide.htmlUrl"></div>
</div>
这里有点工作 fiddle:jsfiddle.net,虽然我不得不在这里和那里填写一些空白。
