我在使用AngularUI Bootstrap的Carousel插件时遇到了麻烦。在我的场景中,我需要读取包含一些模板路径的外部文件,并将它们作为幻灯片加载。见下面的例子:
index.html (正在调用指令)
<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,我将响应数据绑定到{{1数组。当我将$scope.slides
属性推入htmlContent
属性时,轮播行为可以正常工作,但它会将[[object HTMLDivElement]]和类似的东西呈现为项目。
$compile(objResponseInner)($scope)
横幅rotativo.conf
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 = $compile(objResponseInner)(scope);
scope.slides.push({
htmlContent: objContent,
id: intCurrentIndex++
});
});
}
});
}
});
}
}
}]);
加载的模板示例:
{
"slides": {
"banner-ex-one": {
"titulo": "exone",
"caminho-imagem": "assets/one.jpg",
"caminho": "/html/components/banner-rotativo/banner-ex-one.view.html"
},
"banner-ex-two" : {
"titulo": "extwo",
"caminho-imagem": "assets/two.jpg",
"caminho": "/html/components/banner-rotativo/banner-ex-two.view.html"
},
"banner-rav" : {
"title": "rav",
"caminho-imagem": "assets/rav.jpg",
"caminho": "/html/components/banner-rotativo/banner-rav.view.html"
},
"banner-aviso" : {
"title": "Quadro de comunicações 1",
"caminho-imagem": "assets/aviso.jpg",
"caminho": "/html/components/banner-rotativo/banner-aviso.view.html"
},
"banner-custom" : {
"title": "Quadro de comunicações 2",
"caminho-imagem": "assets/custom.jpg",
"caminho": "/html/components/banner-rotativo/banner-custom.view.html"
}
}
}
一些要点:
<div id="frameOne" ng-controller="slideOneController" class="varejo-clique-promocao-one" title="Conteúdo Varejo - Quadro One">
<div class="item">
<div id="dados">
<!-- Imagem banner one -->
<img id="one" ng-click="enviarFormOne()" class="one" alt="" ng-if="1==1" ng-src="caminhoImagem"
/>
<!-- End imagem banner -->
<span ng-if="hasText">{{bannerText}}</span>
</div>
<div id="excecao" class="excecao" ng-if="typeof(one.excecao) !== 'undefined'">
DEU EXCECAO
</div>
<div class="carousel-title" id="tituloOne" ng-if="1==1" title="{{bannerTitle}}">
{{bannerTitle}}
</div>
</div>
因为我注入的模板也有控制器。如果我不使用它,我的控制器不会被处理。当我只是插入没有$compile
的HTML时,它会渲染好。怎么了?
答案 0 :(得分:3)
问题是ng-bind-html
需要html字符串,而你从$compile
得到的结果实际上是一个元素对象。你可以从已编译的元素中获取HTML字符串并传递它,但你可能会遇到各种麻烦。
但实际上,您可以使用ngInclude而不是ng-bind-html跳过$compile
的麻烦。它将为您处理模板请求和编译。
因此,不是请求和编译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>
这是一个有点工作的小提琴:jsfiddle.net,虽然我不得不在这里和那里填补一些空白。
