用angularjs阅读更多选项

Question

我正在使用这指令在我的离子型应用程序中实现一个读-更多。我的HTML看起来如下：

<ion-list>
    <ion-item class="item item-thumbnail-left item-text-wrap" ng-repeat="sh in schedule_hosts" type="item-text-wrap">
        <img ng-src={{sh.imageURL}}>
        <h2>{{sh.firstName}} {{sh.lastName}}</h2>
        <p>{{sh.profession.EN}}</p>
        <p read-more ng-model="content" words="true" length="5"></p>
    </ion-item>
</ion-list>

在我的控制器里：

$scope.content = "Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Morbi commodo, ipsum sed pharetra gravida, orci magna rhoncus neque, id pulvinar odio lorem non turpis. Nullam sit amet enim. Suspendisse id velit vitae ligula volutpat condimentum. Aliquam erat volutpat. Sed quis velit. Nulla facilisi. Nulla libero. Vivamus pharetra posuere sapien. Nam consectetuer. Sed aliquam, nunc eget euismod ullamcorper, lectus nunc ullamcorper orci, fermentum bibendum enim nibh eget ipsum. Donec porttitor ligula eu dolor. Maecenas vitae nulla consequat libero cursus venenatis. Nam magna enim, accumsan eu, blandit sed, blandit a, eros." +
            "Quisque facilisis erat a dui. Nam malesuada ornare dolor. Cras gravida, diam sit amet rhoncus ornare, erat elit consectetuer erat, id egestas pede nibh eget odio. Proin tincidunt, velit vel porta elementum, magna diam molestie sapien, non aliquet massa pede eu diam. Aliquam iaculis. Fusce et ipsum et nulla tristique facilisis. Donec eget sem sit amet ligula viverra gravida. Etiam vehicula urna vel turpis. Suspendisse sagittis ante a urna. Morbi a est quis orci consequat rutrum. Nullam egestas feugiat felis. Integer adipiscing semper ligula. Nunc molestie, nisl sit amet cursus convallis, sapien lectus pretium metus, vitae pretium enim wisi id lectus." +
            "Proin at eros non eros adipiscing mollis. Donec semper turpis sed diam. Sed consequat ligula nec tortor. Integer eget sem. Ut vitae enim eu est vehicula gravida. Morbi ipsum ipsum, porta nec, tempor id, auctor vitae, purus. Pellentesque neque. Nulla luctus erat vitae libero. Integer nec enim. Phasellus aliquam enim et tortor. Quisque aliquet, quam elementum condimentum feugiat, tellus odio consectetuer wisi, vel nonummy sem neque in elit. Curabitur eleifend wisi iaculis ipsum. Pellentesque habitant morbi tristique senectus et netus et malesuada fames ac turpis egestas. In non velit non ligula laoreet ultrices. Praesent ultricies facilisis nisl. Vivamus luctus elit sit amet mi.";

这很好，但正如您所看到的，现在每个项目的内容都是相同的。我正在寻找一种创建读取更多功能的方法，它允许我在HTML中添加文本，如下所示：

<p read-more ng-model="content" words="true" length="5">{{sh.content}}</p>

我对安古拉杰和Ionic非常(非常)新，任何帮助都是非常感谢的！

看来你是在找指令。该指令是与web组件相同的特性。

你的问题可以这样解决。

read-more-content.html

<p ng-if="content" read-more ng-model="content" words="true" length="length">{{content}}</p>

read.more.content.js

angular.module('App')
    .directive('readMoreContent', function () {
        return {
            restrict: 'E',
            transclude: true,
            scope: {
                content: '=',
                length: '='
            },
            templateUrl: 'app/components/_read-more.html'
        };
    });

而且用法也可以类似于这样

<read-more-content content="content" length="5"></read-more-content>

我个人的建议是把你自己的代码分解成小部件/指令。这样你就可以在最近的重构中避免很多麻烦了。我期待着做一些类似于http://bradfrost.com/blog/post/atomic-web-design/的事情，但在角度上。
